Activity did not call finish? (API 23)

Question

I am getting the following error and i have no clue as to why its happening.

Error:

Code:

protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
    System.out.println("Started");
}

I am trying to run the code on an AVD running android 6.0 (API 23), works on API 22.

Answer 1

I'm having the same problem, the same crash with the

did not call finish() prior to onResume() completing

error message. So I created the v23\styles.xml

<style name="AppTheme" parent="android:Theme.Translucent">
...
</style>

while the normal styles.xml has

<style name="AppTheme" parent="android:Theme.NoDisplay">
...
</style>

It works fine, no longer crashes. However, I don't know how good is this solution, to use Theme.Translucent in API 23, especially as it is defined as

Theme for translucent activities (on API level 10 and lower).

I really hope they fix this bug.

I found a workaround. Call setVisible(true) in onStart():

@Override
protected void onStart() {
    super.onStart();
    setVisible(true);
}
