Android Moto Droid相機每次掛在相機上圖片

全部，我一遍又一遍地搜索，找到一個解決方案，同時我發現了一個關於相機發布等問題，我不能爲我的生活似乎得到凸輪代碼上班。每次執行takePicture時，系統都會掛起，有時會調用PictureCallback，但大多數情況下它只是掛起。Android Moto Droid相機每次掛在相機上圖片

有關無法讀取/data/ap_gain.bin文件，奇怪的問題等

下面是代碼：

public class CameraActivity extends Activity implements Camera.PictureCallback, RequestConstants { 

private static final String TAG = "Camera"; 

private Preview preview; 

private boolean previewRunning; 

private int addressNotificationId; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 

    super.onCreate(savedInstanceState); 

    addressNotificationId = getIntent().getIntExtra(REQ_RA_ID, 0); 

    getWindow().setFormat(PixelFormat.TRANSLUCENT); 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

    preview = new Preview(this); 
    } 
    setContentView(preview); 
}

    if (isFinishing()) { 
    preview.cleanup(); 
    } 

    super.onDestroy();

我與Nexus One有同樣的問題。我聽到快門聲，然後什麼都沒有。在調試日誌中，我看到「AudoHardware pcm播放將進入待機狀態」。你有什麼進展？ – 2010-02-08 06:48:54
