[Android-development] using getwindow.setFlags from a JNI activity object

[BogDan]

1- You can't set window flags from Qt thread. Those flags must be set from Android thread.
2- WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON[1] is an integer not a string!


Cheers,
BogDan.

My app is not qml-based, but widget-based, so I am trying to do that using QAndroidJniObject...
My best guess so far is something like that:
QAndroidJniObjectqtActivity=QtAndroid::androidActivity();
QAndroidJniObjectintent("android/content/Intent","()V");
QAndroidJniOject param=QAndroidJniObject::fromString("WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON");
intent.callObjectMethod("addFlags","(I)Landroid/content/Intent;",param.object<jobject>());
qtActivity.callObjectMethod("startActivity","(Landroid/content/Intent;)V",intent.object<jobject>());
 
but of course it does work because it's not the right way to set param. I suppose I need to retrieve the jint value for FLAG_KEEP_SCREEN_ON so I can use it in the intent, but I don't know how to achieve that.
