We do have a bug in where DLC and patches are causing errors due to their folder locations or names of their folders, but that doesn’t seem to be affecting your project in this instance, so I do not believe that bug is relevant. But I did want to mention it, just in case.
I’m using the Enabler version 4.14.2.
I created a first-person template and rotated one of the boxes to test the patch functionality of the mobile device.
I did not find any documentation on the mobile patch feature. I just ran the update according to version 4.14 and automatically generated the Android + DLC configuration file for packaging APK and DLC using a custom startup profile.
I do not know how to test my patch in the local, because the document only windows platform.

If you’ve created your patch correctly, there should be a [ProjectName]\Releases[VersionNumber][PlatformName] folder, next to the original content pak file. If you add the patch pak file from [ProjectName]\Saved\StagedBuilds[PlatformName][ProjectName]\Content\Paks into the folder above, it should update for you. Are you getting that Releases folder?
I found the folder you said,
But I do not know how to update it to Android.
Whether it can provide me with the Android remote patch function of the relevant documents.
The update documentation for 4.14 provides too little information.
My native language is not English, and your conversations have been translated by . I apologize for the inconvenience.
If you add the new patch .pak file that’s located in [ProjectName]\Saved\StagedBuilds[PlatformName][ProjectName]\Content\Paks and add it to the [ProjectName]\Releases[VersionNumber][PlatformName] folder, then your project should update for you on the Android device.
So move the .pak file from the second picture into where the file is for the first picture and that should override the file and the updates should be made.
I hope this helps. 
I did as you suggested, but it did not change.
What I want to know is how to update my game remotely. Your hints seem to refer to actions taken in the path of my local project. I do not know how this will affect the game I installed on Android. Because the screenshot of the two folders and I did not update the folder with any relationship. And the two .pak files look the same size, I guess they are the same thing. I do not know if you see the above four screenshots. I packaged out APK and DLC are in a folder I created the startup configuration file specified inside. I found a small .pak file in the path "HTTPchunks \ DLC1.0 \ Android_ETC2 \ DLC1.0 \ MyThirdPerson ". It seems to be the patch file.
I hope you can re-view my reply with 4 screenshots, including the settings of my startup profile and the generated DLC files, and I would also like you to provide a copy of the documentation on the use of remote patching for mobile devices Thank you very much for your patience.
Since you’ve already packaged your DLC, you’ll need to follow the Play Services documentation:

4.14 Is the update mentioned in the documentation not an autonomous remote update? Also need to pass GooglePlay? That 4.14 update documentation mentioned in the patch function refers to what is it?
We have documentation coming out for this. I can’t provide the exact date yet but it should be quite soon. It’ll go over how to exactly get your blueprint set up properly for this all to work.
Thank you!
Okay I see, I’ll keep watching. thank you very much!
You’re very welcome. Let me know if you have any further questions. I’m hoping the documentation will come out within the next few weeks but keep in mind that delays can happen.
I hop The Documentations come out soon! I’m really stuck in this. I get -1 install progress and -0 download speed , The Blueprint Setup seems to be set up correctly. actually I had a wired problem from the beginning of this process , When I used minimal apk + dlc settings and chose my downloader map again it packaged everything in apk and I had 300 mg apk and 4 mg .pak file , I have checked project settings to insure nothing effecting the launcher cook settings , After working around this , I managed to move all my contents and keep my downloader files , package apk using minimal settings and bring back everything and do the patching , I have uploaded everything to my website host and when I try to download I got -1 progress and -0 speed.
你好，请问这个问题解决了吗？
我在StartInstall的时候报了“ErrorMessage=Could not download patch data. Please check your internet connection, and try again.”。
CloudUrl是“CloudUrl”文件夹的路径吗，最终从这个文件夹下载的文件，是会根据文件自动补全文件下载url是吗？
