Do you support this feature?

TrayContentProvider.java

like this ?

onCreate() >>

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            storageContext = getContext().createDeviceProtectedStorageContext();

            if (storageContext.moveDatabaseFrom(getContext(), TrayDBHelper.DATABASE_NAME)) {
                Log.d("TrayContentProvider", "[TrayDBHelper] TrayDBHelper.DATABASE_NAME.moveDatabaseFrom : true");
            } else {
                Log.d("TrayContentProvider", "[TrayDBHelper] TrayDBHelper.DATABASE_NAME.moveDatabaseFrom : false");
            }

            if (storageContext.moveDatabaseFrom(getContext(), TrayDBHelper.DATABASE_NAME_NO_BACKUP)) {
                Log.d("TrayContentProvider", "[TrayDBHelper] TrayDBHelper.DATABASE_NAME_NO_BACKUP.moveDatabaseFrom : true");
            } else {
                Log.d("TrayContentProvider", "[TrayDBHelper] TrayDBHelper.DATABASE_NAME_NO_BACKUP.moveDatabaseFrom : false");
            }

        } else {
            storageContext = getContext();
        }

        mUserDbHelper = new TrayDBHelper(storageContext, true);
        mDeviceDbHelper = new TrayDBHelper(storageContext, false);

My project using Tray needs this feature too. But I recommend not to modify TrayContentProvider.java to use Context#createDeviceProtectedStorageContext() like @malangstudio 's #133 (comment) . Users should decide if using device protected storage context or a normal context by themselves.

For example:

final Context storageContext;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    storageContext = context.createDeviceProtectedStorageContext();
} else {
    storageContext = context;
}
mPreferences = new TrayPreferences(storageContext, PREF_NAME, 1);

However, I found Tray didn't work well with device protected storage context. I got stack trace logs:

I can guarantee that data can be read and written with device protected storage context. But logs told me the database is readonly. Do you have any idea?
