I\'m looking for a way to open the Android gallery application from an intent.

I do not want to return a picture, but rather just open the gallery to al

1. Following can be used in Activity or Fragment.

    private File mCurrentPhoto;
   

2. Add permissions

3. Add Intents to open "image-selector" and "photo-capture"

   //A system-based view to select photos.
   private void dispatchPhotoSelectionIntent() {
   Intent galleryIntent = new Intent(Intent.ACTION_PICK,
           android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
   this.startActivityForResult(galleryIntent, REQUEST_IMAGE_SELECTOR);
   }
   
   
   
       //Open system camera application to capture a photo.
       private void dispatchTakePictureIntent() {
   Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
   // Ensure that there's a camera activity to handle the intent
   if (takePictureIntent.resolveActivity(App.Instance.getPackageManager()) != null) {
       try {
           createImageFile();
       } catch (IOException ex) {
           // Error occurred while creating the File
       }
       // Continue only if the File was successfully created
       if (mCurrentPhoto != null) {
           takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mCurrentPhoto));
           startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
       }
   }
   }
   

4. Add handling when getting photo.

   @Override
   public void onActivityResult(int requestCode, int resultCode, Intent data) {
   switch (requestCode) {
   case REQUEST_IMAGE_SELECTOR:
       if (resultCode == Activity.RESULT_OK && data != null && data.getData() != null) {
           String[] filePathColumn = { MediaStore.Images.Media.DATA };
           Cursor cursor = App.Instance.getContentResolver().query(data.getData(), filePathColumn, null, null, null);
           if (cursor == null || cursor.getCount() < 1) {
               mCurrentPhoto = null;
               break;
           }
           cursor.moveToFirst();
           int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
           if(columnIndex < 0) { // no column index
               mCurrentPhoto = null;
               break;
           }
           mCurrentPhoto = new File(cursor.getString(columnIndex));
           cursor.close();
       } else {
           mCurrentPhoto = null;
       }
       break;
   case REQUEST_IMAGE_CAPTURE:
       if (resultCode != Activity.RESULT_OK) {
           mCurrentPhoto = null;
       }
       break;
   }
   if (mCurrentPhoto != null) {
       ImageView imageView = (ImageView) [parent].findViewById(R.id.loaded_iv);
       Picasso.with(App.Instance).load(mCurrentPhoto).into(imageView);
   }
   super.onActivityResult(requestCode, resultCode, data);
   }
