Android从摄像头上传图像导致应用程序崩溃

我正在尝试从gallery和camera上传图像。上传gallery图像非常有效，但在尝试从具有http 400状态的camera上传图像时崩溃 //打开意图的方法

private void openImageIntent() {

    // Determine Uri of camera image to save.
    final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "MyDir" + File.separator);
    root.mkdirs();
    final String fname = "thisFile";
    final File sdImageMainDirectory = new File(root, fname);
    outputFileUri = Uri.fromFile(sdImageMainDirectory);

    // Camera.
    final List<Intent> cameraIntents = new ArrayList<Intent>();
    final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    final PackageManager packageManager = getPackageManager();
    final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
    for(ResolveInfo res : listCam) {
        final String packageName = res.activityInfo.packageName;
        final Intent intent = new Intent(captureIntent);
        intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
        intent.setPackage(packageName);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
        cameraIntents.add(intent);
    }

    // Filesystem.
    final Intent galleryIntent = new Intent();
    galleryIntent.setType("image/* video/*");
    galleryIntent.setAction(Intent.ACTION_PICK);

    final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");

    // Add the camera options.
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));

    startActivityForResult(chooserIntent, 1);
}

//上载文件的方法

 public void uploadFile(){
    SharedPreferences sf = LiveChatActivity.this.getSharedPreferences("all", 0);

    String reqUrl = ApiUrls.getEventDetails + "/comments";     
    HashMap<String, String> formValues = new HashMap<>();
    formValues.put("comment_post_ID", event_id);
    formValues.put("comment_author", "ves");//sf.getString("display_name", "comment_author")
    formValues.put("comment_author_email", sf.getString("user_email", "user_email"));
    formValues.put("comment_content", comment_content);

    wUtil.execute();
}

我添加了文件扩展名，效果很好

在第一个函数中，我替换了==>最后一个字符串fname=“thisFile”；

---

最后一个字符串为fname=“thisFile.jpg”

@theUturn还应确保您已定义了所有使用权限。
