Retrieve value from appA to appB using intents

Question

I have two apps (appA and appB). I want to retrieve a single value stored in appA sharedPreferences and use it in appB. Can I do that using intents?. I just need to do this once (on first install of appB).

Answer 1

You should be able to do that adding .putextras() to your intent and then getting them with getExtras() on appB (after checking if they are present at all).

Answer 2

Use Intent to launch appB in appA

// Launch appB in appA
Intent intent = context.getPackageManager().getLaunchIntentForPackage(appB_PackageName);
intent.putExtra("key","value");
startActivity(intent);

Or read sharedPreferences in appB Android: Retrieving shared preferences of other application
