    <p>I am working in one android application. In my application I am capturing images with the use of opencv native camera. When I open camera to capture image, the application crashed. The log file showing "Fatal signal 11 (SIGSEGV) at 0x00000020 (code=1)". I don't know why it is crashed. Can anyone tell me what may the problem? This code is working in emulator. But When I am using in device it crashed. Iam using opencv face detection sample. Code snippet is given below,</p> <pre><code> /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { Log.i(TAG, "onCreate"); super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); Log.i(TAG, "Trying to load OpenCV library"); if (!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_2, this, mOpenCVCallBack)) { Log.e(TAG, "Cannot connect to OpenCV Manager"); } } private BaseLoaderCallback mOpenCVCallBack = new BaseLoaderCallback(this) { @Override public void onManagerConnected(int status) { switch (status) { case LoaderCallbackInterface.SUCCESS: { Log.i(TAG, "OpenCV loaded successfully"); // Load native libs after OpenCV initialization System.loadLibrary("detection_based_tracker"); // Create and set View mView = new FdView(mAppContext); mView.setDetectorType(mDetectorType); mView.setMinFaceSize(0.2f); setContentView(mView); // Check native OpenCV camera if( !mView.openCamera() ) { AlertDialog ad = new AlertDialog.Builder(mAppContext).create(); ad.setCancelable(false); // This blocks the 'BACK' button ad.setMessage("Fatal error: can't open camera!"); ad.setButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { dialog.dismiss(); finish(); } }); ad.show(); } } break; default: { super.onManagerConnected(status); } break; } } }; public FdView(Context context) { super(context); try { InputStream is = context.getResources().openRawResource(R.raw.lbpcascade_frontalface); File cascadeDir = context.getDir("cascade", Context.MODE_PRIVATE); mCascadeFile = new File(cascadeDir, "lbpcascade_frontalface.xml"); FileOutputStream os = new FileOutputStream(mCascadeFile); byte[] buffer = new byte[4096]; int bytesRead; while ((bytesRead = is.read(buffer)) != -1) { os.write(buffer, 0, bytesRead); } is.close(); os.close(); mJavaDetector = new CascadeClassifier(mCascadeFile.getAbsolutePath()); if (mJavaDetector.empty()) { Log.e(TAG, "Failed to load cascade classifier"); mJavaDetector = null; } else Log.i(TAG, "Loaded cascade classifier from " + mCascadeFile.getAbsolutePath()); mNativeDetector = new DetectionBasedTracker(mCascadeFile.getAbsolutePath(), 0); cascadeDir.delete(); } catch (IOException e) { e.printStackTrace(); Log.e(TAG, "Failed to load cascade.

    1. COYou should give a code snippet of how you called opencv. In lieu of that information, I'm leaning towards thinking that this is a bug in the android opencv bindings.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
