Android圆形头像拍照后“无法加载此图片”的问题解决方法（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);    }  }
