App Crashes When Loading Image From Gallery

In my app ,i have two buttons ,one for loading the image from gallery(from device )and another one for taking pictures by accesing the camera of the device,My code is working prope

Solution 1:

I'm not sure but... maybe on some device this "EXTERNAL_CONTENT_URI" doesn't work because there's no external storage?

Solution 2:

This is issue in Lollypop+ devices so we have to write 2 logic to process LoolyPop below & above android versions to process the gallery Image.

Starting Gallery Image Picker Intent,

Intentintent=newIntent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        mContext.startActivityForResult(
                Intent.createChooser(intent, "Complete action using"),
                DigitalCareContants.IMAGE_PICK);

Process the Image,
