I am developing a project which should work as an Android sdk, the project includes:
the mainSdkModule imports moduleA and moduleB this way:
implementation project(':moduleA')
implementation project(':moduleB')
I am publishing the whole project as an SDK that I want to use in another app project. To test the integration of this SDK I am temporarily publishing it to my local maven folder. What happens is that when I import the sdk into the app project, the build fails with the following error:
Could not find sdk-main-package:moduleA:unspecified.
Required by:
project :mainSdkModule > sdk-main-package:core:1.0.0
I could avoid this error by publishing each module as an indipendent library but I need to keep them internal without exposing them.
Is it normal that the app project asks for a dependency that isn't even supposed to be visible by other projects besides the sdk one?
How can I include moduleA and moduleB inside the core and grant access to them for those who import the SDK without exposing these internal modules on maven?
Modules A and B are declared as external dependencies and will be referenced as such in the pom.xml file. Something like this:
<dependency>
<groupId>sdk-main-package</groupId>
<artifactId>moduleA</artifactId>
<version>unspecified</version>
<scope>compile</scope>
</dependency>
What you want is to create a fat jar or a fat aar. A fat jar/aar is a jar/aar file that also includes the dependencies (instead of referencing them as external dependencies). I don't know if your SDK needs to be a jar file or an aar file and if you don't know either then you can find out the difference e.g. here: Android Archive Library (aar) vs standard jar.
If you need a fat jar then you can use the Shadow plugin: https://imperceptiblethoughts.com/shadow/introduction.
If you need a fat aar then you can e.g. use this: https://medium.com/android-news/android-fat-aar-from-gradle-892038facc87. There are other solutions but I haven't personally tested any of them so don't know which ones really work. If you google fat aar you'll get plenty of hits and I hope one of them solves your problem.

I have recently implement paypal mobile payment tutorial using following tutorial: http://androiddevelopmentanddiscussion.blogspot.com/2014/05/paypal-integration-in-android.html
and in response i get following information:
{
"response": {
"state": "approved",
"id": "PAY-1GM934738N157023RKR7OWYI",
"create_time": "2014-12-03T10:52:17Z",

},
"response_type": "payment"
}
{
"short_description": "Painting 1",
"amount": "8",
"intent": "sale",
"currency_code": "USD"
}
any one guide me how can i obtain transaction id and other information in mobile sdk? as i see payment from paypal mobile sdk id is different then the actual transaction id.
any help would be appreciated.
You can retrieve a payment resource using the payment ID returned by the SDK: https://developer.paypal.com/webapps/developer/docs/api/#look-up-a-payment-resource
Typically, this would be done from your server and not from the mobile device. The GET operation will require an access token generated using both your client_id and client_secret.

I'm using code from here: https://github.com/TwilioDevEd/video-quickstart-php to develop a webRTC web app.
The example application, when running successfully on 2 browsers, creates the following HTML:
<div id="remote-media">
<audio src="blob:https%3A//myAddress.com/8a537e34-9ab2-4bea-a85d-61e5f80b585c"></audio>
<video src="blob:https%3A//myAddress.com/22b23b46-9021-4f15-9ab5-ffb78fec2d48"></video>
</div>
<div id="local-media">
<audio src="blob:https%3A//myAddress.com/740c8e33-cc60-4d1e-b1fe-2c23742e618d"></audio>
<video src="blob:https%3A//myAddress.com/3105d4a2-cd71-4408-8b7c-771cba677829"></video>
</div>
It works on Chrome and Firefox on a PC, and works on Firefox on Android.
Chrome on Android connects, there is video and audio input which is visible and audible on the remote browser, and there is video output - the video streamed from the remote browser. THE PROBLEM: there is no audio output.
I have tried $("audio").autoplay="true"; in the javascript that creates the <audio> element.
I have opened other web pages from the same Chrome installation on the same device (eg. YouTube) and I have audio and video.
What am I missing?
"On iOS, and Chrome for Android, autoplay doesn’t work; users must tap the screen to play the video." source: https://developers.google.com/web/fundamentals/design-and-ui/media/video/quick-reference?hl=en#autoplay
My solution:
<button id="audioOn" onclick="$('#remote-media > audio')[0].play()">Cant hear? Click me!</button>
I am using Twilio for SMS verification to my android app using Android Studio, and I found this Dependency from Twilio official documentation(compile 'com.twilio: verification:+'), here is the link: https://www.twilio.com/docs/guides/twilio-verification-sdk-integration-guide/integrating-twilio-verification-sdk-using-sample-backend#step-3-add-twilio-verification-sdk-for-android
but as add this dependency, the Gradle shows error and can not be built, here I have already asked my answer: Error:Failed to resolve: com.google.android.gms:play-services-auth-api-phone:10.2.5
Is there anyone who knows what is the exact dependency of Twilio Verification to add in my Android Studio to use Twilio SMS verification.
another Twilio developer evangelist here.
The issue with that document is that it fails to mention that you will need to use a local Google Play services SDK for the time being until Google releases it out in the wild.
To get that, all you need to do is fill up the form in this page to get the SDK, and the in your code you will do the following:
~/.gradle/gradle.propertiesPARTNER_SDK_DIR=/Users/{USER_NAME}/workspace/partner-sdkSo you should end up with somthing that looks like this:
allprojects {
repositories {
maven {
url PARTNER_SDK_DIR
}
jcenter()
}
}
We have a sample application on our github repository which you can download and test. You will find it here
Hope this helps you!
I have several different item view types in an Android ListView, each with its own LinearLayout. I am trying to center all of their widgets vertically in addition to their being placed horizontally relative to each other. See the the very first item in the ListView in the attached pic. It looks fine except that the widgets are pushed up near the top of the ListView item.
The light blue and light green backgrounds for the TextView and ImageViews are intended to help view the effects of the xml on placement. Immediately below the image is my layout for that topmost item in the ListView. How can I make the TextView as well as the circular images (ImageView) to be centered vertically?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:paddingBottom="5dp">
<TextView
android:id="@+id/ques_num"
android:layout_width="30dp"
android:layout_height="wrap_content"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:layout_marginTop="2dp"
android:layout_marginBottom="2dp"
android:background="@color/LightBlue"
android:text="0."
android:textSize="22sp" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center_vertical"
android:background="@color/LightGreen"
android:adjustViewBounds="true"
android:id="@+id/question_id_0" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center_vertical"
android:background="@color/LightGreen"
android:adjustViewBounds="true"
android:id="@+id/question_id_1" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center_vertical"
android:background="@color/LightGreen"
android:adjustViewBounds="true"
android:id="@+id/question_id_2" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center_vertical"
android:background="@color/LightGreen"
android:adjustViewBounds="true"
android:id="@+id/question_id_3" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center_vertical"
android:background="@color/LightGreen"
android:adjustViewBounds="true"
android:id="@+id/question_id_4" />
</LinearLayout>
UPDATE:
I tried simply adding to the LinearLayout:
android:gravity="center_horizontal"
and afterwards tried changing it to:
android:gravity="center_horizontal|center_vertical"
In both cases it resulted in moving the widgets into the horizontal center of the ListView item, but had no effect on the vertical positioning. See the results here in the image:
The entire problem was a combination of this line in the LinearLayout:
android:paddingBottom="5dp"
and the fact that, given the size of the content in the TextView and ImageView objects, the upper and lower boundaries of the ListView items were already pressing in as much as they could. There was no room for centering adjustments to take place even though it looked like there was, because of the paddingBottom attribute.
My .xml file has the following code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:id="@+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:orientation="vertical"
android:id="@+id/image_list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
However, the phone renders images as follows:
Why?
Are you setting a LayoutManager for the RecyclerView? See this documentation.
setLayoutManager
void setLayoutManager (RecyclerView.LayoutManager layout)
Set the RecyclerView.LayoutManager that this RecyclerView will use.
In contrast to other adapter-backed views such as ListView or GridView, RecyclerView allows client code to provide custom layout arrangements for child views. These arrangements are controlled by the RecyclerView.LayoutManager. A LayoutManager must be provided for RecyclerView to function.
I have a ProgressBar in a ScrollView, and I'd like it to stay centered vertically despite the user scrolling down or up. However, I'm not sure how to accomplish this.
Here's the code that I have, simple as it is. I have an indeterminate ProgressBar:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ocr_scroll_view"
android:layout_width="match_parent"
android:layout_height="fill_parent">
<RelativeLayout android:id="@+id/image_holder"
android:layout_gravity="end"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ImageView android:id="@+id/image"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<ProgressBar android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleLarge"
android:visibility="gone"
android:layout_centerInParent="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
And I call it as such:
spinningProgressBar = (ProgressBar)findViewById(R.id.progressBar1);
spinningProgressBar.setIndeterminate(true);
spinningProgressBar.setVisibility(View.GONE);
Setting its visibility at the appropriate times.
All suggestions very much appreciated.
Put it outside of the ScrollView. Just have the ScrollView and the ProgressBar overlap.
You can read about how to overlap views here: Overlapping Views in Android
There's a couple of ways to do it, ranging from GridLayouts to RelativeLayouts and then programatic ways to do it.

I am working on my first app fully designed by Compose.
I need to centralize vertically text with the Text() compose component. In traditional Android dev practice I did this over alignment property. Text() compose also has alignment property, but at this moment it has limited capacity (Alignment.Horizontal() is only allowed), despite on I noticed different alignment values within Text() when made a research in web. Similar case for Column() - it also has alignment property .wrapContentSize() and also has limitation on values that could be used here, despite on quick research in web shows it may receive CenterVertically too.
What is your way to achieve this visual effect? The full code piece is below
@ExperimentalUnitApi
@Composable
fun TripBookingContent(state: PassengerTripUiState.TripBookUiState) {
Log.d(App.TAG, "[screen] TripBookingContent")
val baselineGrid = dimensionResource(id = R.dimen.baseline_grid)
val mainPadding = dimensionResource(id = R.dimen.main_margin_compact)
var componentSpace = dimensionResource(id = R.dimen.component_space)
Column(
modifier = Modifier
.wrapContentHeight()
.fillMaxWidth()
.padding(
paddingValues = PaddingValues(
horizontal = mainPadding,
vertical = baselineGrid
)
)
) {
TripViewItem(
data = state.trip,
{},
modifier = Modifier.padding(vertical = baselineGrid)
)
Text(
text = stringResource(id = R.string.booking_screen_driver),
color = colorResource(id = R.color.white),
style = TextStyle(textIndent = TextIndent(firstLine = TextUnit(16F, TextUnitType.Sp))),
modifier = Modifier
.height(componentSpace)
.padding(start = baselineGrid)
.fillMaxWidth()
.background(color = colorResource(id = R.color.design_default_color_secondary_variant))
)
Log.d(App.TAG, "[state] state.driver - ${state}")
Log.d(App.TAG, "[state] state.driver.toDriver() - ${state.driver}")
DriverCardContent(data = state.driver)
Text(
text = stringResource(id = R.string.booking_screen_msg),
color = colorResource(id = R.color.white),
style = TextStyle(textIndent = TextIndent(firstLine = TextUnit(16F, TextUnitType.Sp))),
textAlign = TextAlign.Center,
modifier = Modifier
// .height(componentSpace)
.height(32.dp)
.padding(start = baselineGrid)
.fillMaxWidth()
.background(color = colorResource(id = R.color.colorPrimaryDark))
)
/**
* Disable book button at current (alfa version), for more details
* */
Button(
onClick = { /* no op */ },
modifier = Modifier
.alpha(0F)
.fillMaxWidth()
.padding(baselineGrid)
.height(dimensionResource(id = R.dimen.button_height)),
colors = ButtonDefaults.buttonColors(
backgroundColor = Color.Blue,
contentColor = Color.White
),
) {
Text(
text = stringResource(id = R.string.booking_screen_confirm_button),
modifier = Modifier.align(Alignment.CenterVertically),
fontWeight = FontWeight.Bold
)
}
}
}
UPDATE My final solution become this one below. I have to move padding and background to the Box() layer to achieve text in center both vertically and horizontally.
Box(
contentAlignment = Alignment.Center,
modifier = Modifier
.height(32.dp)
.padding(start = baselineGrid)
.fillMaxWidth()
.background(color = colorResource(id = R.color.colorPrimaryDark))
) {
Text(
text = stringResource(id = R.string.booking_screen_msg),
color = colorResource(id = R.color.white),
style = TextStyle(textIndent = TextIndent(firstLine = TextUnit(16F, TextUnitType.Sp))),
textAlign = TextAlign.Center,
/* modifier = Modifier
// .height(componentSpace)
.height(32.dp)
.padding(start = baselineGrid)
.fillMaxWidth()
.background(color = colorResource(id = R.color.colorPrimaryDark))*/
)
}
It's not possible to center vertically only using Text(). I asked similar question here, you need to use Box() with contentAlignment = Alignment.Center. There are also CenterStart and CenterEnd options for alignment either.
Box(
contentAlignment = Alignment.Center,
) {
Text(
text = "Text",
textAlign = TextAlign.Center
)
}
If I spawn a thread in activity and throw an exception like this
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
Thread {
throw java.lang.RuntimeException()
}.start()
}
This will crash the app with FATAL ERROR
If I do equivalent in a pure Java program, the main thread will continue to run. For example:
public class ThreadTest {
public static void main(String args[]) {
System.out.println("Start ");
new Thread(){
public void run() {
System.out.println("Inner Start");
throw new RuntimeException();
}
}.start();
try{
Thread.sleep(3000);
System.out.println("End");
}catch(Exception ignored){ }
}
}
The output will be
Start
Inner Start
Exception in thread "Thread-0" java.lang.RuntimeException
at ThreadTest$1.run(ThreadTest.java:17)
End
What causes this difference in behaviour?
Because the Android Runtime is what actually kills your Android app. Both the behavior of the Java and the Android code are perfectly compliant with the Java Language Specification, which states:
If no catch clause that can handle an exception can be found,
then the **current thread** (the thread that encountered the exception) is terminated
however, in the section about program termination it also states this:
A program terminates all its activity and exits when one of two things happens:
* All the threads that are not daemon threads terminate.
* Some thread invokes the exit method of class Runtime or class System, and the exit operation is not forbidden by the security manager.
While this may make it feel like the Android implementation is non-compliant, that is isn't the case. The JLS says that it must terminate if all threads are terminated, but it doesn't say "an different process can't terminate the program if it detects that one thread is terminated", and the Android Runtime, which is not a JVM and is a different process can terminate the process when it detects an exception. Note that this behavior is similar in native Android code as Android documentation states:
* An app that is written using Java or Kotlin crashes
if it throws an unhandled exception, represented by the Throwable class.
* An app that is written using native-code languages crashes
if there’s an unhandled signal, such as SIGSEGV, during its execution.
I have an app, it uses Rxjava and Retrofit to retrieve data from backend.
after login, I will get a JSON file which includes User information (name, email, id, stripeId....). I will need to use User information when retrieving data from backend in other activities. Since there are many times I need to use the User information, saving it in Database or SharePreference may spend a lot of time.
Is there any way that I can save the data in the memory when the App is alive (not killed in the background)? Thanks first.
You can extend Application Class which is initiated on application startup. Check it here:

I have developed an android app using flutter and I like to use stripe as my payment gateway.
I need to add refer and earn feature in my app. How do I need to setup this with my bank account for providing money one who refers.
I need to provide money like below example.
Example: If A refers B I need to give some referal money for A and If B refers C i need to give money for B and also some referal money for A(referral money for A nd B vary).
If this is not possible in stripe. which payment gateway provides this future ? or How to i do like this?
You need to setup your account as a platform and your users as connected account and you will be able to deduct from their accont and add to the other (receiver) user account.
Any charges goes to your account, and then you can distribute the money to users as you set it up in your platform account. That is one option, the second one is to do everything in your app admin section (calculate the amount to be paid) and create a charge according to your needs.
Read up on that in their doc https://stripe.com/docs/connect/best-practices
I want to set the Razorpay key dynamically.
Can anyone help me with this ?
I have tried with
implementation 'com.razorpay:checkout:1.5.13'
Checkout checkout = new Checkout();
checkout.setKeyID(MY_KEY_HERE);
Still it gives me error to set RazorPay API key in manifest.
Later i tried with custom by setting .aar in libs folder also and tried with
implementation project(name: "razorpay-android-3.8.8", ext: 'aar')
Then it gave me error while building gradle as:
ERROR: Required keys [path] are missing from map {name=razorpay-android-3.8.8, ext=aar}.
Issue resolved with this.
Steps followed:
Checkout.preload(PaymentActivity.this);
Checkout checkout = new Checkout();
checkout.setKeyID(MY_KEY_HERE);
final Activity activity = this;
checkout.open(activity, options);

I am implementing one application.
Based on my application i am created class named "RepeatingAlarm.java"
My RepeatingAlarm class extends broadcastrecevers.
I am calling the above class in every one hour.
My requirement is,when this class is called
I want to get a file from sdcard and send this file through email.
How to do this?
Add these inside onReceive method in your BroadcastReceiver.
File file= new File(Environment.getExternalStorageDirectory()
+ "/filefolder/"+"filename");
Uri u1 = null;
u1 = Uri.fromFile(file);
Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);
sendIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Sending a file");
sendIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]
{"me@gmail.com"});
sendIntent.putExtra(Intent.EXTRA_STREAM, u1);
sendIntent.setType("text/html");
context.startActivity(Intent.createChooser(sendIntent , "Send mail..."));
I have added items to the toolbar menu programmatically. Now I want to access the item's title attribute. I know you can use item.getTitle() to get the title in Java, but how do would you get the title associated to that item in C#?
if you look at the docs for IMenuItem you will see that it has a TitleFormatted property that maps to the Android getTitle method.
Generally Android getPropertyName methods are mapped to C# PropertyName properties in Xamarin.
In some methods of my Activity I want to check the title of menu or know if it is checked or not. How can I get Activity's menu. I need something like this.getMenu()
Be wary of invalidateOptionsMenu(). It recreates the entire menu. This has a lot of overhead and will reset embedded components like the SearchView. It took me quite a while to track down why my SearchView would "randomly" close.
I ended up capturing the menu as posted by Dark and then call onPrepareOptionsMenu(Menu) as necessary. This met my requirement without an nasty side effects. Gotcha: Make sure to do a null check in case you call onPrepareOptionsMenu() before the menu is created. I did this as below:
private Menu mOptionsMenu;
@Override
public boolean onCreateOptionsMenu(final Menu menu) {
mOptionsMenu = menu
...
}
private void updateOptionsMenu() {
if (mOptionsMenu != null) {
onPrepareOptionsMenu(mOptionsMenu);
}
}
