I upgraded Android Studio to 2.3.3
and then I installed Android SDK Build-Tools 26
and Android 8.0 (O)
and set compileSdkVersion and targetSdkVersion on 26
and buildToolsVersion on "26.0.0"
and then I changed all the libraries version from 25.3.1 to 26.0.0-alpha1
Now I have the below RunTime Exception:

the (MainActivity.java:65) and (FragmentDrawer.java:83) are displayed as link.
MainActivity.java:65 content:
setContentView(R.layout.activity_main);
FragmentDrawer.java:83 content:
setTargetFragment(FragmentDrawer.this, 100);
before MainActivity there is a SplashActivity and it runs without any problem!
I've just downgraded SDK Build-Tools, compileSdkVersion, targetSdkVersion, buildToolsVersion and libraries version to run again and test. there is no problem using previews versions.
Can anyone help me? How can I run my App using new SDK Version?
The problem is here:
java.lang.IllegalArgumentException:
Setting FragmentDrawer{28990c1 #0 id=0x7f0f0095} as the target of
FragmentDrawer{28990c1 #0 id=0x7f0f0095} would create a target cycle
at android.support.v4.app.Fragment.setTargetFragment(Fragment.java:636)
setTargetFragment has changed in 26.0.0. Before, it simply set the target fragment plus request code. From 26.0.0 onwards, it contains two checks before doing that:
- it checks whether the current fragment and the target fragment belong to the same fragment manager
- it checks whether setting the target fragment would create a loop, by scanning the list of target fragments in this fragment and see if the target fragment is already there.
So somehow you are setting a target fragment that you set before. That is no longer allowed.
