android - java.lang.RuntimeException: 传递结果失败 ResultInfo{who=null, request=65637, result=-1, data=Intent

Question

我有一个图库照片选择工具，但每次选择它时，我的程序都会出错。我无法纠正错误，我尝试了许多不同的方法，但我没有工作。我在等待帮助。

下面是我用来从图库中选择照片的功能。

private void openPickImageIntent() {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Bir Görsel Seçin"), PICK_IMAGE);
}

这是我的 onResult 函数。

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == PICK_IMAGE && resultCode == Activity.RESULT_OK) {

        Uri selectedImage = data.getData();
        String[] filePathColumn = {MediaStore.Images.Media.DATA};
        Cursor cursor = getActivity().getContentResolver().query(selectedImage, filePathColumn, null, null, null);
        if (cursor == null)
            return;

        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String filePath = cursor.getString(columnIndex);
        cursor.close();

        String token = SatekApplication.getInstance().getLoginResponseDto().getToken();
        File file = new File(filePath);

        RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), file);
        MultipartBody.Part body = MultipartBody.Part.create(reqFile);
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        RequestBody name = RequestBody.create(MediaType.parse("text/plain"), photoFileName + ".jpg");//todo test

        Call<ResponseBody> req = service.uploadImage(token, asset.getUploadUrl(), reqFile);
        EventBus.getDefault().post(new ShowLoadingDialogEvent());
        photoUploadingProgressBar.setVisibility(View.VISIBLE);
        buttonUploadImage.setEnabled(false);
        imageViewTick.setVisibility(View.GONE);
        req.enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                EventBus.getDefault().post(new HideLoadingDialogEvent());
                createAsset();
            }

            @Override
            public void onFailure(Call<ResponseBody> call, Throwable t) {
                EventBus.getDefault().post(new HideLoadingDialogEvent());
                photoUploadingProgressBar.setVisibility(View.GONE);
                buttonUploadImage.setEnabled(true);
                t.printStackTrace();
            }
        });
    }
}

这是我收到的错误：
