無法連接到G1上的相機服務

我爲這篇較長的文章提前道歉，但有必要說明發生了什麼。無法連接到G1上的相機服務

我一直在研究一個適用於1.6模擬器的應用程序，但在我的G1上使用炸彈。

這裏是攝影師的活動：

public class Photographer extends Activity { 

private SurfaceView preview = null; 
private SurfaceHolder previewHolder = null; 
private Camera camera = null; 
public static final int IMAGE_HEIGHT = 320; 
public static final int IMAGE_WIDTH = 480; 

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

    preview = (SurfaceView)findViewById(R.id.preview); 
    previewHolder = preview.getHolder(); 
    previewHolder.addCallback(surfaceCallback); 
    previewHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); 
} 

private void takePicture() { 
    camera.stopPreview(); 
    camera.takePicture(null, null, photoCallback); 
} 

SurfaceHolder.Callback surfaceCallback = new SurfaceHolder.Callback() { 
    public void surfaceCreated(SurfaceHolder holder) { 
    camera = Camera.open(); 

    try { 
    camera.setPreviewDisplay(previewHolder); 
    } 
    catch (Throwable t) { 
    Log.e("Photographer", "Exception in setPreviewDisplay()", t); 
    } 
    try { 
    takePicture(); 
    } catch (Throwable t) { 
    Log.e("Photographer", "Exception in takePicture()", t); 
    } 
    } 

    public void surfaceChanged(SurfaceHolder holder, 
     int format, int width, int height) { 
    Camera.Parameters parameters=camera.getParameters(); 
    parameters.setPreviewSize(IMAGE_WIDTH, IMAGE_HEIGHT); 
    parameters.setPictureFormat(PixelFormat.JPEG); 
    camera.setParameters(parameters); 
    camera.startPreview(); 
    } 

    public void surfaceDestroyed(SurfaceHolder holder) { 
    camera.stopPreview(); 
    camera.release(); 
    camera = null; 
    } 
}; 

Camera.PictureCallback photoCallback = new Camera.PictureCallback() { 
    public void onPictureTaken(byte[] data, Camera camera) { 
    new SavePhotoTask().execute(data); 
    camera.startPreview(); 
    } 
}; 

class SavePhotoTask extends AsyncTask<byte[], String, String> { 
    @Override 
    protected String doInBackground(byte[]... jpeg) { 
    File photo = new File(Environment.getExternalStorageDirectory(), "WIIA-new.jpg"); 
    if (photo.exists()) 
    photo.renameTo(new File(Environment.getExternalStorageDirectory(), "WIIA-old.jpg")); 

    try { 
    FileOutputStream fos = new FileOutputStream(photo.getPath()); 

    fos.write(jpeg[0]); 
    fos.close(); 
    Log.e("Photographer", "Picture taken"); 
    // returning result 
     Intent returnIntent = new Intent(); 
     setResult(RESULT_OK, returnIntent);  
     finish(); 
    } 
    catch (java.io.IOException e) { 
    Log.e("Photographer", "Exception in photoCallback", e); 

    // returning result 
     Intent returnIntent = new Intent(); 
    setResult(RESULT_CANCELED, returnIntent); 
    finish(); 
    } 

    return(null); 
    } 
} 

}

和這裏是本次活動得到來自名爲：

public class WIIA extends Activity { 

public class CountDown extends CountDownTimer { 
    private TextView tvCountDown = (TextView) findViewById(R.id.progress); 
    private TextView tvSystemState = (TextView) findViewById(R.id.system_state); 

    public CountDown(long millisInFuture, long countDownInterval) { 
    super(millisInFuture, countDownInterval); 
    } 

    @Override 
    public void onFinish() { 
    tvSystemState.setText(R.string.system_state_armed); 
    tvCountDown.setText(R.string.armed); 
    snapshotInterval = Long.parseLong(settings.getString("snapshot_interval_list", "5")); 
    imgCaptureTimer = new Timer("imageCapture"); 
    imgCaptureTimer.scheduleAtFixedRate(doRefresh, 0, snapshotInterval*1000); 
    } 

    @Override 
    public void onTick(long millisUntilFinished) { 
    tvCountDown.setText(millisUntilFinished/1000 + " seconds until Armed"); 
    } 

} 

private TimerTask doRefresh = new TimerTask() { 
    public void run() { 
    if (armed) { 
    refreshImage(); 
    } else { 
    imgCaptureTimer.cancel(); 
    } 
    } 
}; 

private void refreshImage() { 
    Thread updateThread = new Thread(null, backgroundCaptureImage, "capture_image"); 
    updateThread.start();   
} 

private Runnable backgroundCaptureImage = new Runnable() { 
    public void run() { 
    doRefreshImage(); 
    }   
}; 

private void doRefreshImage() { 
    Intent photographer = new Intent(this, Photographer.class); 
    startActivityForResult(photographer, GET_PHOTO); 
} 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    switch(requestCode) { 
    case (GET_PHOTO) : { 
    if(resultCode == RESULT_OK) { 
    // go on to compare images 
    new ProcessImageTask().execute(); 
    } 
    break; 
    } 
    } 
}

順利粘貼AndroidManifest.xml中的相關部分，但是我有權限照相機：

<uses-permission android:name="android.permission.CAMERA" />

這裏是攝影師部分：

 <activity android:name=".Photographer" 
    android:configChanges="keyboardHidden|orientation" 
    android:screenOrientation="landscape" 
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen"> 
    </activity>

還爲測試在G1：

android:debuggable="true"

和關閉的1.6工作：

<uses-sdk android:minSdkVersion="4" />

所有這些工作在一個1.6模擬器，但是當我在G1上運行此，LogCat顯示：

這聽起來像問題是超時問題，但我不知所措的地方，我應該尋找....沒有任何人有線索？

謝謝！

我認爲這是夢幻般的，我現在還在2015年 – 2015-03-05 22:42:39

嘗試定義應用程序標記外的許可標記，像下面，我希望這有助於：

<manifest ......> <uses-permission android:name="android.permission.CAMERA" /> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity ... .....> </application> </manifest>

救了我一個真正的痛苦THX很多 – TheFuquan 2014-10-10 11:50:31

最有可能的cameraService這是媒體過程的一部分在後臺崩潰。如果您只是嘗試在Android中運行默認相機應用程序，並且不顯示，那麼只需重新引導設備即可解決此問題。

有無論如何，要解決這個問題的代碼，我捕捉異常，但不能準確告訴用戶重新啓動他們的設備。 – sgarman 2011-09-14 18:22:09

這也適用於我，但斯曼說我不能告訴用戶重新啓動他的手機。 – 2013-09-17 14:31:19

您不應該在takePicture之前調用stopPreview。

http://developer.android.com/reference/android/hardware/Camera.html

6.Important：呼叫startPreview（）開始更新預覽表面。必須先開始預覽，然後才能拍攝照片。

private void takePicture() { 
    // WRONG: camera.stopPreview(); 
    camera.takePicture(null, null, photoCallback); 
}
