Android圆形头像，拍照后“无法加载此图片”的问题解决（适配Android7.0）

Feature: 点击选择拍照或者打开相册，选取图片进行裁剪最后设置为圆形头像。
Problem: 拍好照片，点击裁剪，弹Toast“无法加载此图片”。
Solution: 在裁剪的class里加两行代码

intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

主要代码如下：

    public static final String PHOTO_IMAGE_FILE_NAME = "fileImg.jpg";
    public static final int CAMERA_REQUEST_CODE = 100;
    public static final int IMAGE_REQUEST_CODE = 101;
    public static final int RESULT_REQUEST_CODE = 102;
    private File tempFile = null;
    private Uri imageUri;

    //跳转相机
    private void toCamera() {

        File outputImage = new File(getActivity().getExternalCacheDir(),
                PHOTO_IMAGE_FILE_NAME);
        try {
            if (outputImage.exists()) {
                outputImage.delete();
            }
            outputImage.createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
        }

        if (Build.VERSION.SDK_INT >= 24) {
            imageUri = FileProvider.getUriForFile(getActivity(),
                    "com.liushengjie.smartbutler.fileprovider", outputImage);
        } else {
            imageUri = Uri.fromFile(outputImage);
        }
        //启动相机程序
        Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
        intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
        startActivityForResult(intent, CAMERA_REQUEST_CODE);
        dialog.dismiss();

    }

    //跳转相册
    private void toPicture() {
        Intent intent = new Intent(Intent.ACTION_PICK);
        intent.setType("image/*");
        startActivityForResult(intent, IMAGE_REQUEST_CODE);
        dialog.dismiss();
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode != getActivity().RESULT_CANCELED) {
            switch (requestCode) {
                //相机数据
                case CAMERA_REQUEST_CODE:
                    //tempFile = new File(Environment.getExternalStorageDirectory(), PHOTO_IMAGE_FILE_NAME);
                    //startPhotoZoom(Uri.fromFile(tempFile));
                    startPhotoZoom(imageUri);
                    break;
                //相册数据
                case IMAGE_REQUEST_CODE:
                    startPhotoZoom(data.getData());
                    break;
                case RESULT_REQUEST_CODE:
                    //有可能点击舍弃
                    if (data != null) {
                        //拿到图片设置
                        setImageToView(data);
                        //删除原来的图片
                        if (tempFile != null) {
                            tempFile.delete();
                        }
                    }
                    break;
            }
        }
    }

    //裁剪
    private void startPhotoZoom(Uri uri) {
        if (uri == null) {
            L.e("uri == null");
            return;
        }

        Intent intent = new Intent("com.android.camera.action.CROP");
        intent.setDataAndType(uri, "image/*");
        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        intent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
        //裁剪
        intent.putExtra("crop", true);
        //宽高比例
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
        //图片质量
        intent.putExtra("outputX", 320);
        intent.putExtra("outputY", 320);
        //发送数据
        intent.putExtra("return-data", true);
        startActivityForResult(intent, RESULT_REQUEST_CODE);
    }

    //设置图片
    private void setImageToView(Intent data) {
        Bundle bundle = data.getExtras();
        if (bundle != null) {
            Bitmap bitmap = bundle.getParcelable("data");
            profile_image.setImageBitmap(bitmap);
        }
    }
