Mobile app crash on Android 13

Creatorczyk

Hi,
I raised the API of my mobile application written in Qt5.15 to 33. From now on, after uploading the application to the phone, the application turns on for 1 second and then turns off if it is Android 13. There is no such problem on Android 11. What may be the problem?

I don't get much information in the console. How could I identify the problem?

Did you run through debugger?

@jsulm Hi, I found the cause of the error. It turns out that Android 13 withdrew the "WRITE_EXTERNAL_STORAGE" permissions.
https://medium.com/@muhammadbilal4074/storage-permission-in-android-13-89372e543864

auto result = QtAndroid::checkPermission(QString("android.permission.WRITE_EXTERNAL_STORAGE"));
if(result == QtAndroid::PermissionResult::Denied){
        QtAndroid::PermissionResultMap resultHash = QtAndroid::requestPermissionsSync(QStringList({"android.permission.WRITE_EXTERNAL_STORAGE"}));
        if(resultHash["android.permission.WRITE_EXTERNAL_STORAGE"] == QtAndroid::PermissionResult::Denied){
            return 0;
}
}

I removed these permissions, but I think I need them to read the SQLite database. Because the application closes when you try to perform an operation on it. I also tried replacing it with "READ_MEDIA_IMAGES" but it didn't help.

auto result = QtAndroid::checkPermission(QString("android.permission.READ_MEDIA_IMAGES"));
if(result == QtAndroid::PermissionResult::Denied){
       QtAndroid::PermissionResultMap resultHash = QtAndroid::requestPermissionsSync(QStringList({"android.permission.READ_MEDIA_IMAGES"}));
       if(resultHash["android.permission.READ_MEDIA_IMAGES"] == QtAndroid::PermissionResult::Denied){
               return 0;
       }

How could I fix this error?

So, did you investigate why? Run through debugger to see what happens.

@Creatorczyk which version of 5.15 are you using ?
