我使用开放源代码加入,为我的应用程序添加了新的可能性。用于编辑声音。 现在,我无法将文件发送到活动且遇到错误的

编辑语音的新活动:

// Result codes
private static final int REQUEST_CODE_CHOOSE_CONTACT = 1;

/**
 * This is a special intent action that means "edit a sound file".
 */
public static final String EDIT = "com.example.soundrecorder.action.EDIT";

//
// Public methods and protected overrides
//

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
    Log.v("Ringdroid", "EditActivity OnCreate");
    super.onCreate(icicle);

    mPlayer = null;
    mIsPlaying = false;

    mAlertDialog = null;
    mProgressDialog = null;

    mLoadSoundFileThread = null;
    mRecordAudioThread = null;
    mSaveSoundFileThread = null;

    Intent intent = getIntent();

    // If the Ringdroid media select activity was launched via a
    // GET_CONTENT intent, then we shouldn't display a "saved"
    // message when the user saves, we should just return whatever
    // they create.
    mWasGetContentIntent = intent.getBooleanExtra("was_get_content_intent", false);

    mFilename = intent.getData().toString().replaceFirst("file://", "").replaceAll("%20", " ");
    mSoundFile = null;
    mKeyDown = false;

    mHandler = new Handler();

    loadGui();

    mHandler.postDelayed(mTimerRunnable, 100);

    if (!mFilename.equals("record")) {
        loadFromFile();
    } else {
        recordAudio();
    }
}

private void closeThread(Thread thread) {
    if (thread != null && thread.isAlive()) {
        try {
            thread.join();
        } catch (InterruptedException e) {
        }
    }
}

/** Called when the activity is finally destroyed. */
@Override
protected void onDestroy() {
    Log.v("Ringdroid", "EditActivity OnDestroy");

    mLoadingKeepGoing = false;
    mRecordingKeepGoing = false;
    closeThread(mLoadSoundFileThread);
    closeThread(mRecordAudioThread);
    closeThread(mSaveSoundFileThread);
    mLoadSoundFileThread = null;
    mRecordAudioThread = null;
    mSaveSoundFileThread = null;
    if(mProgressDialog != null) {
        mProgressDialog.dismiss();
        mProgressDialog = null;
    }
    if(mAlertDialog != null) {
        mAlertDialog.dismiss();
        mAlertDialog = null;
    }

    if (mPlayer != null) {
        if (mPlayer.isPlaying() || mPlayer.isPaused()) {
            mPlayer.stop();
        }
        mPlayer.release();
        mPlayer = null;
    }...

我选择和发送声音进行编辑的活动:

}

我不知道如何发送正确的信息。

发送方法: 公共无效editFileActivity
