Unsolved AndroidIntent and QAndroidJniObject

[SeDi]

Hi,
still trying to solve this Android problem, I am trying to add an "extra" to an Intent that is going to be raised via the ALARM_SERVICE.

The problem is: to call the putExtra(...) method, I need a QAndroidIntent. The pendingIntent I have, is but a QAndroidJniObject.

Following the docs,

QAndroidIntent realIntent(pendingIntent);

wraps(!) my pendingIntent, so I try to add the "extra" that way:

realIntent.putExtra(QString("SCREEN"),QString("Camera"));

Then I set the AlarmManager with pendingIntent:

alarmManager.callMethod<void>("set",
                                          "(IJLandroid/app/PendingIntent;)V",
                                          QAndroidJniObject::getStaticField<jint>("android/app/AlarmManager", "RTC"),
                                          jlong(QDateTime::currentMSecsSinceEpoch() + 500), pendingIntent.object());

But, apparently, the "extra" is NOT being set in the original pendingIntent (so it is obviously a different object), as this Q_ASSERT fails:

            QAndroidIntent realIntent(pendingIntent);
            realIntent.putExtra(QString("SCREEN"),QString("Camera"));

            QAndroidIntent realIntent2(pendingIntent);
            Q_ASSERT(realIntent2.extraVariant("SCREEN").toString()=="Camera");

I've tried to call the method via ->callOptionMethod() and ->callStaticOptionMethod(), but I have trouble, probably my type specificatios are wrong. Trying out many combinations yielded the following error messages...

W System.err: java.lang.ClassNotFoundException: Didn't find class "Intent" on path: DexPathList[[],nativeLibraryDirectories=[/system/lib, /system/vendor/lib]]

W System.err: java.lang.NoSuchMethodError: no static method "Landroid/content/Intent;.putExtra(Ljava/lang/String;Ljava/lang/String;)Landroid/content/Intent;"

How can I "cast back" the proper AndroidIntent, equipped with an "extra", back to a QAndroidJniObject, suitable for the set(...) method?
Alternatively: how can I add the "extra" to a QAndroidJniObject intent?

Any help welcome.

Maybe instead of passing pendingIntent to "set" method try to pass realIntent.handle().object()?

[SeDi]

Thank you, @IntruderExcluder!
I can do that (and it gave me more insight!), but it doesn't solve the problem, I'm afraid.

Interestingly,

QAndroidIntent realIntent(pendingIntent);
realIntent.putExtra(QString("SCREEN"), QString("Camera"));
debugLog.write(QString("realIntent: "+realIntent.extraVariant("SCREEN").toString()+"\n").toLocal8Bit());

results in

realIntent: 

It apparently didn't work to put the extra into the Intent in the first place - so my problem might be even more basic.

Furthermore, this code on starting the app

QAndroidJniObject intent = activity.callObjectMethod("getIntent", "()Landroid/content/Intent;");
if (intent.isValid()) {
    debugLog.write("intent: " + intent.toString().toLocal8Bit()+"\n");
}

shows extras (in its string description) only when it's not a restart. The output for normal starts:

intent: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=de.herrdiel.punktlandung/org.qtproject.qt5.android.bindings.QtActivity bnds=[859,1339][1137,1748] (has extras) }

The output for restarts:

intent: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 pkg=de.herrdiel.punktlandung cmp=de.herrdiel.punktlandung/org.qtproject.qt5.android.bindings.QtActivity }

So, at least, I can detect, if it is a restart or not (different Strings), but I still can't submit more specific information - and I am not sure if all Android versions implement these Strings identically.

The problem seems to be, how to properly put the Extra into the intent.

@SeDi said in AndroidIntent and QAndroidJniObject:

realIntent.putExtra(QString("SCREEN"), QString("Camera"));
debugLog.write(QString("realIntent: "+realIntent.extraVariant("SCREEN").toString()+"\n").toLocal8Bit());
~
results in
realIntent:

It should be "realIntent: Camera", shouldn't it?

Can that possibly be a bug in Qt?
Or is it just me misunderstanding a concept?
