android - 不能使用 MediaStore.Images.Media.insertImage

Question

我有一个项目正在商店中运行，突然客户开始提示无法使用我的应用程序捕获图像，尽管我没有在这部分进行任何更改我只是更新了 android 并为问题制作了一个新版本与捕获图像无关

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();
                    }
                });
            }
        }

后台报错如下

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

当然，我已经在我的 list 中的应用程序以及运行时许可和用户接受中请求了READ_EXTERNAL_STORAGE、WRITE_EXTERNAL_STORAGE、CAMERA对话框，但仍然报错

谁能帮忙吗？

当用户拒绝权限或点击不再显示时，您是否处理过发生的情况？您应该在权限被禁用时禁用该功能，或者反复提示直到授予权限。

编辑:

Android 现在使用 maxSdkVersion 过滤器限制 WRITE_EXTERNAL_STORAGE 权限。在某些用例中，例如如果应用程序包含需要此权限的依赖项，maxSdkVersion 会使这些依赖项无法授予或请求权限。这些情况的解决方案是稍后在依赖树中声明 tools:node="replace" list 合并策略:

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