我的问题是如何加密字符串:

String AndroidId;

@Override
public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.download_movie_activity);

  cancel = (Button)findViewById(R.id.img_cancle);

  linear= (LinearLayout)findViewById(R.id.progress);
  linear.setVisibility(View.GONE);

  String encrypted = "MzIyNTE2" + "OTQNzM4NTQ=";

  Log.e("Encrypt", encrypted);

  WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
  WifiInfo wInfo = wifiManager.getConnectionInfo();
  AndroidId = wInfo.getMacAddress();

  AndroidId=encrypted;

    database.execSQL("DELETE FROM " + TABLE_Languages + " WHERE " + KEY_SID + "= '" + title + "'" + "and" + "" + KEY + "= '" + titles + "'" );

    //Close the database
    database.close();
}

KEY_SID和KEY是我的列名.

DatabaseHandler.class

public class DataBaseHandlers extends SQLiteOpenHelper {
