I am not sure it will solve your problem, but in many cases there is a permission request problem in API 23 or above.

I also faced the same problem in my project, which I resolved by using bellow procedure.

To avoid No DRP key due to exception:java.lang.ClassNotFoundException request permission in Splash screen in above API 23

Eg:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    permission = Settings.System.canWrite(this);
} else {
    permission = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_SETTINGS) == PackageManager.PERMISSION_GRANTED;
}
if (!permission) {
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
        intent.setData(Uri.parse("package:" + getPackageName()));
        startActivityForResult(intent, CODE_WRITE_SETTINGS_PERMISSION);

    }
}

after checking the above permission, check the remaining permissions in onActivityResult, one by one.

e.g,

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {

    Log.v("Permission", Manifest.permission.WRITE_EXTERNAL_STORAGE+"  Permission is revoked");
    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, CODE_WRITE_SETTINGS_PERMISSION);

    return;
}
