Android SQLite Check If Record Exists Doesn't Work

I'm checking if a sqlLite table record is available or not , it's giving me that the record is available even if it's not

public void checkIfExcist(Context mCtx, String recordName, String ValueCheck) {

    DatabaseHelper mDbHelper = new DatabaseHelper(mCtx);
    SQLiteDatabase mDb = mDbHelper.getWritableDatabase();

    Cursor mCursor = mDb.rawQuery("SELECT * FROM " + SQLITE_TABLE
            + " WHERE " + recordName + " ='" + ValueCheck + "'", null);

    if (mCursor != null) {

        Toast.makeText(mCtx, "Available", 3000).show();
        /* record exist */
    } else {
        Toast.makeText(mCtx, "Not Available", 3000).show();
        /* record not exist */
    }

}
