capture image from camera and crop not working

问题

here is my camera intent.

            File file = getExternalFilesDir(Environment.DIRECTORY_DCIM);
            file.mkdirs();
            File output = new File(file, "profile_image");
            if (output.exists()) {
                output.delete();
            }
            Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

            captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, output);
            startActivityForResult(captureIntent, PublicValues.IMAGE_FROM_CAMERA);

in onActivityresult

if (requestCode == PublicValues.IMAGE_FROM_CAMERA) { 

                if (mPhotoUri != null) {
                    performCrop(mPhotoUri);
                } else {
                    pictureUri = data.getData();
                    performCrop(pictureUri);
                }

and crop intent

            Intent cropIntent = new Intent("com.android.camera.action.CROP");
            cropIntent.setDataAndType(picUri, "image/*");
            cropIntent.putExtra("crop", "true"); // set crop properties
            cropIntent.putExtra("aspectX", 1);  // indicate aspect of desired crop(ratio)
            cropIntent.putExtra("aspectY", 1);
            cropIntent.putExtra("return-data", true); // retrieve data on return
            cropIntent.putExtra("outputX", profileImage.getWidth());   // indicate output X and Y
            cropIntent.putExtra("outputY", profileImage.getHeight());

            startActivityForResult(cropIntent, PublicValues.IMAGE_CROP);

it works fine with API 19 device but crashes in Marshmallow device.

crash report is like this:-

Caused by android.os.FileUriExposedException: file:///storage/emulated/0/WhatsApp/Media/WhatsApp Images/IMG-20170721-WA0014.jpg exposed beyond app through Intent.getData()

回答1:

use Gradle :

compile 'com.theartofdev.edmodo:android-image-cropper:2.3.+'

and try this:

private void performCrop(Uri imageUri) {
    CropImage.activity(imageUri)
            .setGuidelines(CropImageView.Guidelines.ON)
            .setCropShape(CropImageView.CropShape.RECTANGLE)
            .setAspectRatio(1, 1)
            .setMultiTouchEnabled(true)
            .start(this);
}
