OpenCV和Android Studio：「不幸的應用程序已停止」

我試圖通過使用OpenCV訪問Android相機。我在創建項目方面取得了成功，並且運行沒有任何問題。我試圖使用來自互聯網的代碼，並在我的項目中檢查它。但是，應用程序停滯了。這似乎是一個RuntimeException問題，但我不知道如何解決它。這是我的代碼，我從這個網站http://people.oregonstate.edu/~robinsti/CS_496/Tutorial/複製：OpenCV和Android Studio：「不幸的應用程序已停止」

mainActivity.java

public class MainActivity extends AppCompatActivity implements View.OnTouchListener, CameraBridgeViewBase.CvCameraViewListener2{ 

private CameraBridgeViewBase mOpenCvCameraView;

    super.onCreate(savedInstanceState, persistentState); 
    setContentView(R.layout.activity_main); 

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); 
    mOpenCvCameraView = (CameraBridgeViewBase) findViewById(R.id.Surface); 
    mOpenCvCameraView.setVisibility(SurfaceView.VISIBLE); 
    //mOpenCvCameraView.setMaxFrameSize(176, 152); 
    mOpenCvCameraView.setCvCameraViewListener(this); 
} 

private BaseLoaderCallback mLoaderCallBack = new BaseLoaderCallback(this) { 
    @Override 
    public void onManagerConnected(int status) { 
     super.onManagerConnected(status); 
     switch (status) { 
      case LoaderCallbackInterface.SUCCESS: { 
       mOpenCvCameraView.enableView(); 
       mOpenCvCameraView.setOnTouchListener(MainActivity.this);

      default: {

'無法開始活動ComponentInfo {com.tech.te.app/com.tech.te.app.MainActivity}：java.lang.IllegalStateException：您需要使用Theme.AppCompat主題（或後代）機智h此活動。' –

謝謝。現在應用程序不會崩潰，但我沒有看到相機。我應該如何解決這個問題？ – Leonid

你正在OnDestroy上加載OpenCV，你不應該那樣做。

@Override 
public void onDestroy() { 
    super.onDestroy(); 

    if(!OpenCVLoader.initDebug()) { 
     OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_3_1_0,this, mLoaderCallBack); 
    } 
    else { 
     mLoaderCallBack.onManagerConnected(LoaderCallbackInterface.SUCCESS); 
    } 
}

此外，您不應該同時使用initDebug和initAsync。

initDebug是用於靜態初始化的，你需要在你的apk裏面有庫。

initAsync用於安裝OpenCV管理器。

靜態初始化，有一個很好的答案Here

的onResume，在onPause和的onDestroy應該是這樣的：

@Override 
protected void onResume() 
{ 
    super.onResume(); 
    _javaCameraView.enableView(); 
} 

@Override 
protected void onPause() { 
    if (_javaCameraView != null) { 
     _javaCameraView.disableView(); 
    } 
    super.onPause(); 
} 

@Override 
public void onDestroy() { 
    if (_javaCameraView != null) { 
     _javaCameraView.disableView(); 
    } 
    super.onDestroy(); 
}

有關靜態初始化一些信息：

public class MainActivity extends Activity implements CameraBridgeViewBase.CvCameraViewListener2 { 

private static boolean openCVStarted = false; 
JavaCameraView _javaCameraView; 

    static{ 
     System.loadLibrary("opencv_java3"); 


     if(!OpenCVLoader.initDebug()) { 
      Log.d("ERROR", "Unable to load OpenCV"); 
      openCVStarted = false; 
     } else { 
      Log.d("SUCCESS", "OpenCV loaded"); 
      openCVStarted = true; 
     } 
    } 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     _javaCameraView = (JavaCameraView)findViewById(R.id.cameraView); 
     //_javaCameraView.setMaxFrameSize(size.width, size.height); 
     _javaCameraView.setVisibility(SurfaceView.VISIBLE); 
     _javaCameraView.setCvCameraViewListener(this); 
     _javaCameraView.enableView(); 
     _javaCameraView.enableFpsMeter(); 
    } 

    @Override 
    public Mat onCameraFrame(CameraBridgeViewBase.CvCameraViewFrame inputFrame) 
    { 
     _imgBgrTemp = inputFrame.rgba(); 
     // Work with the frame here 
     return _imgBgrTemp; 
    }

我更改了有關主題和應用程序的代碼。然後我改變onResume，onPause和onDestroy函數和應用程序崩潰。有什麼問題？ – Leonid

在對其功能進行任何調用之前，您必須初始化OpenCV。你想在Android上進行靜態初始化或使用OpenCV管理器？ –

我將該項目設置爲「靜態初始化」。函數應該如何？ – Leonid
