Question

In my application when I call camera intent by:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_REQUEST);

it not call onActivityResult() method.

Problem in my application is that some time it calls this method, but some time after capturing photo it again come to photo capture screen.

Before capturing photo I am saving a lot of data in onSaveInstanceState() after that I am collecting this data by onRestoreInstanceState().

Here I don’t know why some time onActivityResult() method calls but some time this method does not call after entering into the photo capture mode.

onActivityResult() code:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
    String fileName = null;
    try {
        if (requestCode == CAMERA_REQUEST) {
            roughBitmap = (Bitmap) data.getExtras().get("data");
            final ContentResolver cr = getContentResolver();
            final String[] p1 = new String[] {
                MediaStore.Images.ImageColumns._ID,
                    MediaStore.Images.ImageColumns.DATE_TAKEN };
            Cursor c1 = cr.query(
                MediaStore.Images.Media.EXTERNAL_CONTENT_URI, p1, null,
                        null, p1[1] + " DESC");
                if (c1.moveToFirst()) {
                    String uristringpic = "content://media/external/images/media/"
                            + c1.getInt(0);
                    newuri = Uri.parse(uristringpic);
                    // Log.i("TAG", "newuri "+newuri);
                    snapName = getRealPathFromURI(newuri);
                    Uri u = Uri.parse(snapName);

                    File f = new File("" + u);
                    fileName = f.getName();
                }
                c1.close();

                  setImageParameter();

            }
        } catch (NullPointerException e) {

        }
        System.out.println("*** End of onActivityResult() ***");
    }

public void setImageParameter() {
    // decode full image
    roughBitmap = BitmapFactory.decodeFile(snapName);
    // calc exact destination size
    Matrix matrix = new Matrix();
    RectF inRect = new RectF(0, 0, roughBitmap.getWidth(),
            roughBitmap.getHeight());
    // RectF outRect = new RectF(0, 0, dstWidth, dstHeight);
    RectF outRect = new RectF(0, 0, 640, 480);
    matrix.setRectToRect(inRect, outRect, Matrix.ScaleToFit.CENTER);
    float[] values = new float[9];
    matrix.getValues(values);
    // resize bitmap
    resizedBitmap = Bitmap.createScaledBitmap(roughBitmap,
            (int) (roughBitmap.getWidth() * values[0]),
            (int) (roughBitmap.getHeight() * values[4]), true);

    paint = new Paint();
    paint.setColor(Color.GREEN);
    paint.setTextSize(16);
    paint.setTextAlign(Paint.Align.LEFT);

    Canvas canvas = new Canvas(resizedBitmap);

    canvas.drawText(String.valueOf(lat), resizedBitmap.getWidth() - 290, resizedBitmap.getHeight() - 50, paint);
    canvas.drawText(String.valueOf(lng), resizedBitmap.getWidth() - 140, resizedBitmap.getHeight() - 50, paint);
    if (!editTextRoadName.getText().toString().equalsIgnoreCase("")) {
        canvas.drawText(editTextRoadName.getText().toString(), resizedBitmap.getWidth() - 290, resizedBitmap.getHeight() - 30, paint);
    }
    canvas.drawText(new DateClass().getSysDateTimeForPhoto(), resizedBitmap.getWidth() - 290, resizedBitmap.getHeight() - 10, paint);



    if (nFinalOrientation == 1) {
        matrix.postRotate(90);
    } else {
        matrix.postRotate(0);
    }


    rotatedBitmap = Bitmap.createScaledBitmap(resizedBitmap,
            (int) (resizedBitmap.getWidth() * values[0]),
            (int) (resizedBitmap.getHeight() * values[4]), true);

    if (booleanPhotoFlag) {
        booleanPhotoFlag = false;
        photoBitmap = rotatedBitmap.copy(Bitmap.Config.ARGB_8888, true);
        imageViewPhoto.setImageBitmap(photoBitmap);

    } else {
        landmarkBitmap = rotatedBitmap.copy(rotatedBitmap.getConfig(), rotatedBitmap.isMutable() ? true : false);
        imageViewLocationPhoto.setImageBitmap(landmarkBitmap);
    }

}

Answer 1

I have created a Camera Library Project you can use this to take picture. I would suggest you to use this library to take picture

EDIT 2:

Look try placing a log between protected void onActivityResult(int requestCode, int resultCode, Intent data) and super.onActivityResult(requestCode, resultCode, data); to see if even that method is being called or not, If its called then check the value that is returned. AND The onActivityResult is not called by your activity but by the calling activity in this case the intent of MediaStore.ACTION_IMAGE_CAPTURE so your onActivityResult has to be called by the setResult() of the calling activity. But I hope your not trying to pass the bitmap via intent like here
