Description
I'm trying to execute this Java code:
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
wl.acquire();
using Qt QAndroidJniObject (I'm deploying a Qt app on Android).
I did that:
QAndroidJniObject activity = QAndroidJniObject::callStaticObjectMethod("org/qtproject/qt5/android/QtNative", "activity", "()Landroid/app/Activity;");
if ( activity.isValid() )
{
QAndroidJniObject serviceName = QAndroidJniObject::getStaticObjectField<jstring>("android/content/Context","POWER_SERVICE");
if ( serviceName.isValid() )
{
QAndroidJniObject powerMgr = activity.callObjectMethod("getSystemService", "(Ljava/lang/String;)Ljava/lang/Object;",serviceName.object<jobject>());
if ( powerMgr.isValid() )
{
QAndroidJniObject wakeLock = powerMgr.callObjectMethod("newWakeLock", "(ILjava/lang/String;)Landroid/os/PowerManager/WakeLock;", levelAndFlags,tag.object<jstring>());
if ( wakeLock.isValid() )
wakeLock.callMethod<void>("acquire", "()V");
else
assert( false );
}
}
}
Checked from the debugger: `levelAndFlags` is correct (6), `tag` is correct ("My Tag"), but `wakeLock.isValid()` returns false.
