Android KitKat image Crop

Question

I pass the image url to the following method

private void performCrop(Uri imageUri){ try { Intent intent = new Intent("com.android.camera.action.CROP"); // intent.setType("image/*"); intent.setDataAndType(imageUri, "image/*"); List<ResolveInfo> list = getActivity().getPackageManager().queryIntentActivities( intent, 0 ); int size = list.size(); if (size >= 0) { intent.setData(imageUri); intent.putExtra("crop", "true"); intent.putExtra("aspectX", 0); intent.putExtra("aspectY", 0); intent.putExtra("outputX", 150); intent.putExtra("outputY", 150); intent.putExtra("scale", true); intent.putExtra("scaleUpIfNeeded", true); intent.putExtra("return-data", true); Intent i = new Intent(intent); ResolveInfo res = list.get(0); i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name)); System.out.println("before startActivityForResult"); try{ startActivityForResult(i, 2); }catch(Exception e){ e.printStackTrace(); } } } catch(ActivityNotFoundException anfe){ String errorMessage = "Whoops - your device doesn't support the crop action!"; //Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT); //toast.show(); } } 

some images are cropped, but some images are missing. When I crop the image, my application activity is closed and the application starts its previous or start activity, what is the problem?

The main problem is that I do not receive any warnings or errors in the log cat, and when I debug it to "System.out.println (" before startActivityForResult "); the program excutes, this means that it does not enter or calls onActivityResult ().

the onActivityResult method is used here.

  @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub super.onActivityResult(requestCode, resultCode, data); if(requestCode ==2 && resultCode == getActivity().RESULT_OK){ System.out.println("inside logic..."); try{ if (data != null) { // get the returned data Bundle extras = data.getExtras(); // get the cropped bitmap Bitmap bmp = extras.getParcelable("data"); imageView.setImageBitmap(bmp); } }catch(Exception e){ e.printStackTrace(); } } }

Android all devices do not have circumcision intentions according to @CommonsWare http://commonsware.com/blog/2013/01/23/no-android-does-not-have-crop-intent.html

it's better to use libraries

Answer 2

this code works successfully for me.try it

 private static final int CAMERA_REQUEST = 1; public static final int MEDIA_TYPE_IMAGE = 1; final int PIC_CROP = 12; Button btnCamera; ImageView iv; Uri picUri; static File mediaFile, sendFile; btnCamera.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub onImgProfile(); } }); void onImgProfile() { Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); picUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, picUri); startActivityForResult(captureIntent, CAMERA_REQUEST); } private Uri getOutputMediaFileUri(int type) { return Uri.fromFile(getOutputMediaFile(type)); } private File getOutputMediaFile(int type) { File mediaStorageDir = new File( Environment.getExternalStorageDirectory(), "MyCameraApp"); if (!mediaStorageDir.exists()) { if (!mediaStorageDir.mkdirs()) { Log.d("MyCameraApp", "failed to create directory"); return null; } } // Create a media file name String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss") .format(new Date()); if (type == MEDIA_TYPE_IMAGE) { mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".jpg"); } else { return null; } return mediaFile; } @SuppressWarnings("unchecked") @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub super.onActivityResult(requestCode, resultCode, data); if (requestCode == CAMERA_REQUEST) { // if (Build.VERSION.SDK_INT < 19) { try { if (mediaFile.exists()) { performCrop(); // new SavePhotoData().execute(); } } catch (Exception e) { // TODO: handle exception } // } } else if (requestCode == 11) { try { picUri = data.getData(); Log.i("uri", "" + picUri); performCrop(); } catch (Exception e) { // TODO: handle exception } } else if (requestCode == PIC_CROP) { // get the returned data try { Bundle extras = data.getExtras(); // get the cropped bitmap Bitmap thePic = extras.getParcelable("data"); // retrieve a reference to the ImageView // display the returned cropped image iv.setImageBitmap(thePic); File mediaStorageDir = new File( Environment.getExternalStorageDirectory(), "MyCameraApp"); if (!mediaStorageDir.exists()) { if (!mediaStorageDir.mkdirs()) { Log.d("MyCameraApp", "failed to create directory"); } } // Create a media file name String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss") .format(new Date()); sendFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".png"); FileOutputStream fOut = new FileOutputStream(sendFile); thePic.compress(Bitmap.CompressFormat.PNG, 85, fOut); fOut.flush(); fOut.close(); } catch (Exception e) { e.printStackTrace(); } } if (resultCode == 3) { Bundle b = data.getExtras(); b.getString("msg"); } }; private void performCrop() { // take care of exceptions try { // call the standard crop action intent (the user device may not // support it) try { Intent cropIntent = new Intent("com.android.camera.action.CROP"); // indicate image type and Uri cropIntent.setDataAndType(picUri, "image/*"); // set crop properties cropIntent.putExtra("crop", "true"); // indicate aspect of desired crop cropIntent.putExtra("aspectX", 1); cropIntent.putExtra("aspectY", 1); // indicate output X and Y cropIntent.putExtra("outputX", 256); cropIntent.putExtra("outputY", 256); // retrieve data on return cropIntent.putExtra("return-data", true); // start the activity - we handle returning in onActivityResult startActivityForResult(cropIntent, PIC_CROP); } catch (Exception e) { // TODO: handle exception } } // respond to users whose devices do not support the crop action catch (ActivityNotFoundException anfe) { // display an error message String errorMessage = "Whoops - your device doesn't support the crop action!"; Toast toast = Toast.makeText(getApplicationContext(), errorMessage, Toast.LENGTH_SHORT); toast.show(); } } 

This code works not only for kitkat, but for all kinds of android
