Question

我有一个正在商店中运行的项目，突然间客户开始抱怨无法使用我的应用程序捕获图像，尽管我在这部分没有做任何更改，但我只是更新了android并进行了新的发行与捕获图像无关

这是我的代码

@Override
        public void saveImage(PictureTransaction xact, Bitmap bitmap) {
            String path = MediaStore.Images.Media.insertImage(getActivity().getContentResolver(), bitmap, getPhotoFilename(), null);

            if(path == null) {
                final Activity activity = getActivity();

                activity.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(activity, getString(R.string.photo_save_error_toast), Toast.LENGTH_SHORT).show();
                        mTakePictureBtn.setEnabled(true);
                        mProgressDialog.dismiss();
                    }
                });
            } else {
                Uri contentUri = Uri.parse(path);
                final Image image = getImageFromContentUri(contentUri);

                // run the media scanner service
                // MediaScannerConnection.scanFile(getActivity(), new String[]{path}, new String[]{"image/jpeg"}, null);
                getActivity().sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, contentUri));

                // the current method is an async. call.
                // so make changes to the UI on the main thread.
                getActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        ((ImagePickerActivity) getActivity()).addImage(image);
                        mTakePictureBtn.setEnabled(true);
                        mProgressDialog.dismiss();
                    }
                });
            }
        }

后台发生的错误如下

Failed to insert image
    java.lang.SecurityException: Permission Denial: writing com.android.providers.media.MediaProvider uri content://media/external/images/media from pid=5494, uid=10570 requires android.permission.WRITE_EXTERNAL_STORAGE, or grantUriPermission()
        at android.os.Parcel.readException(Parcel.java:1693)

        at nl.changer.polypicker.camera.ImageCleanupTask.run(ImageCleanupTask.java:136)

当然，我已在清单中的应用程序中以及在运行时权限中请求了 READ_EXTERNAL_STORAGE ， WRITE_EXTERNAL_STORAGE ， CAMERA ，并且用户接受了对话框，但仍给出该错误

任何人都可以帮忙吗？

您是否处理了用户拒绝权限或单击“不再显示”时发生的情况？您应该在禁用权限时禁用该功能，或者一次又一次提示直到获得权限为止。

编辑：

Android现在使用maxSdkVersion过滤器来限制WRITE_EXTERNAL_STORAGE权限。在某些情况下，例如如果应用程序包含需要此权限的依赖项，则maxSdkVersion使得这些依赖项无法授予或请求该权限。这些情况的解决方案是稍后在依赖关系树中声明tools：node =“ replace”清单合并策略：

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="replace"/>

不能使用MediaStore.Images.Media.insertImage
