I would like my Android app to launch another app on a dedicated area of the screen, i.e. set the screen bounds within which the other app will be displayed. Below is a screenshot with an example of how this could look, where I have launched Google Maps overlaid on my app:
This is achieved by the following code:
final String packageName = "advanced.scientific.calculator.calc991.plus";
new Handler().postDelayed(() -> {
final int[] location = new int[2];
containerLayout.getLocationOnScreen(location);
final Rect appBounds = new Rect(location[0], location[1],
location[0] + containerLayout.getWidth(),
location[1] + containerLayout.getHeight());
final ActivityOptions launchOpts = ActivityOptions.makeBasic();
launchOpts.setLaunchBounds(appBounds);
final Intent intent = getPackageManager().getLaunchIntentForPackage(packageName);
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
intent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
startActivity(intent, launchOpts.toBundle());
}, 5000);
The above result would be satisfactory, however this is run on a Samsung Galaxy S10 device running Android 10. Now, I need to be able to achieve a similar result using Android 9. I have looked into the picture-in-picture and freeform modes, but I have not managed to use the former for this purpose, and the latter unfortunately only seems to be available from Android 10 and up. I am open to any solution for this, including creating a launcher app, etc. I am also looking to maximize compatibility with third-party apps.
What are the possible ways to achieve this on Android 9?
