Android Build for SDK 26 failed with 'processReleaseResources FAILED' aapt.exe error

PowerNow

Hi,
after changing the Android target SDK from 21 to 26 (because of dynamic permissions) on Qt5.11.1/Win10 I get the following error during the build process.

...
Successfully started process 'command 'D:\PROGRAMS\Android\sdk-24.4.1\build-tools\24.0.1\aapt.exe''
:processReleaseResources FAILED
:processReleaseResources (Thread[main,5,main]) completed. Took 8.011 secs.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':processReleaseResources'.
> com.android.ide.common.process.ProcessException: Failed to execute aapt

* Try:
Run with --stacktrace option to get the stack trace. Run with --debug option to get more log output.

BUILD FAILED

Building the android package failed!
16:58:04: The process "D:\PROGRAMS\Qt\Qt5.11.1\5.11.1\android_armv7\bin\androiddeployqt.exe" exited with code 14.
Error while building/deploying project geoeye (kit: Android for armeabi-v7a (GCC 4.9, Qt 5.11.1 for Android armv7))
When executing step "Build Android APK"
16:58:05: Elapsed time: 04:30.

1.) Tools/options/devices/android/SDK Manager everthing seems ok:
"Android settings are OK. (SDK Version 25.2.5, NDK Version: 10.4.0)"

2.) I installed all SDK Tool versions with the SDK Manager sdk-24.4.1

Why does Android Settings show SDK 25.2.5 and Build failure 24.0.1?

Does maybe anyone know whats going wrong here?

For others you have the same problem. I solved this issue by completely replaced all android files of the project.

Delete your Build
Delete the Android folder of your project
Projects/Build Android APK/Create Templates
