App runs with QtCreator but fails to start in standalone mode
-
Hi all,
I'm having a problem with an Android app that I do not know how to explain.
I have an application based on shared libraries that use shared libraries themselves. When I launch the application via QtCreator, the application starts normally. If, after disconnecting the tablet from the development pc, I launch the application directly on the tablet, it does not start (the application stops at launch as if it was missing a dependency). I specify that I use ANDROID_EXTRA_LIBS to embed specific libraries in the APK.
I tried to get the logs through logcat, but I do not understand what component is missing.
Below, the last logcat lines from my app (01-player).I tried to launch the application through adb via "adb shell
am start -a org.qtproject.example.a01_player / .ActivityName "but the return status is always the same: Starting: Intent {act = org.qtproject.example.a01_player / .ActivityName}
Error: Activity not started, unable to resolve Intent {act = org.qtproject.example.a01_player / .ActivityName flg = 0x10000000}.Context : Win10/ndk-r10e/Qt5.11/g++/device with Android 8/ API21
Is there a tool like 'ldd' to list dependencies ? Gradle dependencies ?
Thanks for any idea or suggestion?Sincerely,
David.LOGCAT :

Do you bundle Qt libraries inside the .apk? (it's a checkbox in project build settings)
-
Thanks for you answer.
I thought about it but I can not find this option anymore in the settings. It was in Projects> Build> Android Build APK> Qt Deployment but on the QtCreator 4.6.1 version (Qt5.11) the settings of Projects> Build> Build Android APK> Advanced Actions no longer give access to this choice.
I will try to force all qt libs in the apk (explicitly).
