Activity did not call finish? (API 23)

问题:

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.

回答1:

This is a bug in Android M developer preview. More details

回答2:

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

while the normal styles.xml has

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.

回答3:

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

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

回答4:

My invisible Activity shows a confirmation dialog. This did lose the material design look when I used android:Theme.Translucent.NoTitleBar.

So, based on answers above and CommonWare's blog and the Android themes definitions I use this style, which extends a normal AppCompat.Light theme:

where android 23> https://www.youtube.com/watch?v=NAcUGwCkrcs

Manifest:

android:theme="@android:style/Theme.Translucent.NoTitleBar" Activity extends from Activity. Not AppCompatActivity.

and for version >= 23

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){          getWindow().setStatusBarColor(getResources().getColor(android.R.color.transparent))}

回答6:

Try changing targetSdkVersion to 22 in build.gradle. Theme.NoDisplay shows error in api level 23.
