How to include C++ static libraries into the android apk of a QtApp, when building with Gradle
-
@Nelson_Piquet
a static lib is already included into your binary at link time, otherwise you would already have an error there.
So you should debug your crash using the debugger.@raven-worx Good point. I will be glad if I don't have to do anything special for the static libs. I am looking through the logcat of my android device to analyze.
Btw, following is the apk creation step in my build-script with --gradle, Is there anything wrong you see ?
androiddeployqt --sign mykeystore myKeyalias --storepass myPassword --gradle clean build --output android --verbose --input android-libMyQtApp.so-deployment-settings.json
Can I add something more to correct my build ? Is there anything wrong you see ?

check the catlog. Ther should be more info what exactly caused the crash and where. -

@Nelson_Piquet
did you create the Android tempaltes (as described here) so that the android classes are also deployed? -
I have the Androidmanifest file & the res folder inside MyAppfolder/android with ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android in MyApp.pro set. However, I have to move the manifest file 6 res folder inside MyAppfolder/android/src/main for gradle to build without issues.
-
by the way, I am doing this build command line using the following install step
androiddeployqt --sign mykeystore.keystore myAlias --storepass myPassword --gradle clean build --output android --verbose --input android-libMyApp.so-deployment-settings.json

@Nelson_Piquet
so you are not using QtCreator? -
@Nelson_Piquet
so you are not using QtCreator?@raven-worx In my team all use QtCreator including me as well. But, we need to make a build-script for jenkins & Continious Integration.
The build-script builds successfully when built with ant that comes by default with androiddeployqt We need the android part to build using gradle. Hence, I have appended this --gradle to androiddeployqt command & trying to build this with gradle.
Again, the reason of trying to use gradle here is for versioning. If you google how to auto-increment version number of android app, then everybody suggests to do it with gradle. I dont know why ? Everybody suggest to move on to gradle in the android community specially. May be there are other reasons as well. At the moment I am just trying to build our QtApp using gradle

IIRC Qtcreator shows the build command in the console during the build -
@Nelson_Piquet
IIRC Qtcreator shows the build command in the console during the build@raven-worx Yeah. I got that from the compile log of qtCreator. Thats really good about Qt. The command is correctly set now otherwise the build would not succeed. I think I am missing some dependency/plugin or something in build.gradle which is causing the following error & crashing the app on launch
"Didn't find class "org.qtproject.qt5.android.bindings.QtApplication" on path: DexPathList[[zip file "/data/app/com.mycompany.myapp-2/base.apk"],nativeLibraryDirectories=[/data/app/com.mycompany.myapp-2/lib/arm, /data/app/com.mycompany.myapp-2/base.apk!/lib/armeabi-v7a, /vendor/lib, /system/lib]]"
