How to make intent chooser for camera or gallery application in android like whatsapp editprofile?

Question

I am developing an application where i need to have a dialog choose for uploading image from gallery or camera. I have found kind of solution here Dialog to pick image from gallery or from camera but the problem is here there is clash in comparing which action is chosen by user.

I would like to know if i can modify in this code and get some result to differentiate either gallery or camera is chosen and then apply action.

Create new method into Main Activity File called “selectImage()”..for choose option

private void selectImage() {
    final CharSequence[] items = { "Take Photo", "Choose from Library",
            "Cancel" };

    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    builder.setTitle("Add Photo!");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int item) {
            if (items[item].equals("Take Photo")) {
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                File f = new File(android.os.Environment
                        .getExternalStorageDirectory(), "temp.jpg");
                intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
                startActivityForResult(intent, REQUEST_CAMERA);
            } else if (items[item].equals("Choose from Library")) {
                Intent intent = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                intent.setType("image/*");
                startActivityForResult(
                        Intent.createChooser(intent, "Select File"),
                        SELECT_FILE);
            } else if (items[item].equals("Cancel")) {
                dialog.dismiss();
            }
        }
    });
    builder.show();
}

Now we need return back to our activity with proper Result.

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if (requestCode == REQUEST_CAMERA) {
            File f = new File(Environment.getExternalStorageDirectory()
                    .toString());
            for (File temp : f.listFiles()) {
                if (temp.getName().equals("temp.jpg")) {
                    f = temp;
                    break;
                }
            }
            try {
                Bitmap bm;
                BitmapFactory.Options btmapOptions = new BitmapFactory.Options();

                bm = BitmapFactory.decodeFile(f.getAbsolutePath(),
                        btmapOptions);

                // bm = Bitmap.createScaledBitmap(bm, 70, 70, true);
                ivImage.setImageBitmap(bm);

                String path = android.os.Environment
                        .getExternalStorageDirectory()
                        + File.separator
                        + "Phoenix" + File.separator + "default";
                f.delete();
                OutputStream fOut = null;
                File file = new File(path, String.valueOf(System
                        .currentTimeMillis()) + ".jpg");
                try {
                    fOut = new FileOutputStream(file);
                    bm.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
                    fOut.flush();
                    fOut.close();
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        } else if (requestCode == SELECT_FILE) {
            Uri selectedImageUri = data.getData();

            String tempPath = getPath(selectedImageUri, MainActivity.this);
            Bitmap bm;
            BitmapFactory.Options btmapOptions = new BitmapFactory.Options();
            bm = BitmapFactory.decodeFile(tempPath, btmapOptions);
            ivImage.setImageBitmap(bm);
        }
    }
}

Add this method in onactivity()

 public String getPath(Uri uri, Activity activity) {
    String[] projection = { MediaColumns.DATA };
    Cursor cursor = activity
            .managedQuery(uri, projection, null, null, null);
    int column_index = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}

Answer 2

Just an advice when you call startActivityForResult() to take a photo with camera:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(cameraIntent, REQUEST_CAMERA);
}

Notice that the startActivityForResult() method is protected by a condition that calls resolveActivity(), which returns the first activity component that can handle the intent. Performing this check is important because if you call startActivityForResult() using an intent that no app can handle, your app will crash. So as long as the result is not null, it's safe to use the intent.
