How to use an In-app update API




In this post, we use In-App Update API of the Android app. By using this API, when an update is available then it will show you a notification about update your app and by clicking on update, it installs an update inside your app without interacting with the play store.

To use In-app update API, in the android app we use a Play core library in our Gradle file.

Use In-app Update API code anywhere in your MainActivity or after your Sign-in Activity where you want to tell users about the new updates.

build.gradle
 implementation 'com.google.android.play:core:1.7.3'  
Then in your Java file add this code
 import androidx.appcompat.app.AppCompatActivity;  
 import android.content.IntentSender;  
 import android.os.Bundle;  
 import com.google.android.play.core.appupdate.AppUpdateInfo;  
 import com.google.android.play.core.appupdate.AppUpdateManager;  
 import com.google.android.play.core.appupdate.AppUpdateManagerFactory;  
 import com.google.android.play.core.install.model.AppUpdateType;  
 import com.google.android.play.core.install.model.UpdateAvailability;  
 import com.google.android.play.core.tasks.OnSuccessListener;  
 public class Sample extends AppCompatActivity {  
   AppUpdateManager appUpdateManager;  
   int RequestUpdate = 1;  
   @Override  
   protected void onCreate(Bundle savedInstanceState) {  
     super.onCreate(savedInstanceState);  
     setContentView(R.layout.activity_sample);  
     //use this anywhere in your start screen activity, like after sign in activity  
     appUpdateManager = AppUpdateManagerFactory.create(this);  
     appUpdateManager.getAppUpdateInfo().addOnSuccessListener(new OnSuccessListener<AppUpdateInfo>() {  
       @Override  
       public void onSuccess(AppUpdateInfo result) {  
         if((result.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE)  
           && result.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE))  
         {  
           try {  
             appUpdateManager.startUpdateFlowForResult(  
                 result,  
                 AppUpdateType.IMMEDIATE,  
                 Sample.this,  
                 RequestUpdate);  
             }  
           catch (IntentSender.SendIntentException e)  
           {  
             e.printStackTrace();  
           }  
         }  
       }  
     });  
   }  
   @Override  
   protected void onResume() {  
     super.onResume();  
     appUpdateManager.getAppUpdateInfo().addOnSuccessListener(new OnSuccessListener<AppUpdateInfo>() {  
       @Override  
       public void onSuccess(AppUpdateInfo result) {  
         if(result.updateAvailability() == UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS)  
         {  
           try {  
             appUpdateManager.startUpdateFlowForResult(  
                 result,  
                 AppUpdateType.IMMEDIATE,  
                 Sample.this,  
                 RequestUpdate);  
           }  
           catch (IntentSender.SendIntentException e)  
           {  
             e.printStackTrace();  
           }  
         }  
       }  
     });  
   }  
 }  
 // After this code, you have successfully implement update API  
 // To Test this code goto play console, Open your App  
 // Under Development tools, under Internal app sharing upload your apk and then again generate signed bundle with higher  
 // version name and check your app update status from installed apk.  
 // Thanks//  

If you want to test an app update then here is the solution for that.

Open your app on Google Play Console. Then Under Development Tools -> Open Internal App Sharing

In App Update Api Test

Then Under Manage Uploaders -> Create new List -> Enter List name and Email id (only with this Email id you can update your app)

Then Update your app here or link given in manage uploaders 

  • In this link upload your signed APK.
  • Copy link after uploading an app
  • Transfer that link to your android mobile.
  • Open it by logging into Email id you filled in test list
  • Install an App from here.
  • Then again generate a signed APK with higher version code
  • Upload it to internal app sharing again.
  • Again Copy new Link from there
  • Transfer that link to your android mobile.
  • Do not update that app from here.
  • Open the app and your Update Window shown.
  • Update your app within the app itself.
