[Android]context.startActvity(intent) throwing ActivityNotFoundException

Question

My use case is to switch from App1 to App2 . In App1, I use the packageManager.getPackageInfo() API to check whether the App2 is present or not. When it returns true, I set the intent with intent.setPackage(App2) and trigger the context.startActivity(intent) API. But there are times when context.startActivity(intent) API throws ActivityNotFoundException: App2 is present in the device. The intent has been set in App2 and android:exported is also set to true.

This issue is happening from Android 12. Any inputs be would be highly appreciated!

There is an official documentation on how to prepare an Activity to be launched from outside of the app: https://developer.android.com/training/basics/intents/filters

Furthermore there are multiple examples on how to launch an external activity, maybe check out these two examples (Source for the examples):

1.

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("com.package.address","com.package.address.MainActivity"));
startActivity(intent);

2.

Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address");
if (launchIntent != null) { 
    startActivity(launchIntent);//null pointer check in case package name was not found
}
