不知道改了什么，没有提示上面的错误了。

修改前

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);

Uri fileUri = FileProvider.getUriForFile(getContext(), getString(R.string.org_easydarwin_update_authorities), mSubFiles[holder.getAdapterPosition()]);
intent.setDataAndType(fileUri, "video/*");
startActivity(intent);

修改后

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri uri = Uri.parse(path);
Log.i(TAG, uri.toString());
intent.setDataAndType(uri, "video/mp4");
startActivity(intent);

Mate9可以播放，但4X不行，点了没反应。

因为有效的地址是这样path=content://media/external/video/media/8292

实际上path=/storage/emulated/0/EasyRTMP/2019_08_20_19_04_38-0.mp4

但神奇的是Mate9可以播放。

解：加授权

intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

完整代码

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);

File file = new File(path);
Uri fileUri;
fileUri = FileProvider.getUriForFile(getContext(), getString(R.string.org_easydarwin_update_authorities), file);
Log.i(TAG, fileUri.toString());
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
intent.setDataAndType(fileUri, "video/mp4");
