Answer 1

I found the solution:

• Activity A starts activity B with extra parameter (intent.putExtra("something", true))
• Activity B:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getIntent().hasExtra("something") && getIntent().getBooleanExtra("something", false) {
            //show activity B
        setContentView(R.layout.activity_B);
    } else {
            //don't show activity B, start activity C
        startActivityForResult(activity_C, ACTIVITY_NOT_INITIALIZED); //start activity C
    }
}

//when came back from activity C, check if activity B was already initialized

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == ACTIVITY_NOT_INITIALIZED) {
        //show activity B
        setContentView(R.layout.activity_B);
  }
}

Answer 2

You can call startActivity, without calling setContentView for a layout. Hope this helps!

Answer 3

In your manifest set

android:theme="@android:style/Theme.NoDisplay"

for your activity.

Answer 4

do not set setContentView() for activity B

Answer 5

just call startActivity() in onCreate() method of activity B. It will not be shown, but it will be in activity stack.
