Android app playStore failure Vulnerability

问题

App uploaded in playstore. Its not searchable in playstore also if i use link getting error

1. "App is not compatible with this device" (already set to available in all countries)
2. In playStore production upload,getting App vulnerability issues in notification

By mentioning my Content provider file of my framework ---> delete while delete method is here:

public class ContentProviderClass extends ContentProvider {

    public static final int OUTBOX = 90;
    public static final int OUTBOX_WITH_STATUS = 150;
    public static final int OUTBOX_WITH_ID = 156;

    private static final UriMatcher sUriMatcher = buildUriMatcher();
    private FrameworkDBHelper mOpenHelper;

    @Override
    public boolean onCreate() {
        mOpenHelper = new FrameworkDBHelper(getContext());
        return true;
    }


    @Override
    public int delete(Uri uri, String selection, String[] selectionArgs) {
        final SQLiteDatabase db = mOpenHelper.getReadableDatabase();
        final int match = sUriMatcher.match(uri);
        int rowsDeleted=0;
        switch(match)
        {
            case OUTBOX:{
                rowsDeleted = db.delete(OutboxContract.OutboxEntry.TABLE_NAME,
                selection,
                selectionArgs);
                break;
        }
        default:
            throw new UnsupportedOperationException("Unknown URI: " + uri);
        }

        if(selection == null || rowsDeleted != 0)
            getContext().getContentResolver().notifyChange(uri,null);

        return rowsDeleted;
    }
}

What's the solution to overcome this problem?
