Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Cuoxia,

How did you create your patch file for your project? Are you able to reproduce this in a sample project, or is it only happening in your original project?

Thanks! :)

Hi Samantha, I use the ThirdPerson C++ sample project, the profiles of shipping release&patch are exactly same as official document. When I copy the Pak file to sdcard\UE4Game\PakTest\PakTest\Content\Paks and reopen the app, same popup message shows:"Failed to open descriptor file ''../../../PakTest/PakTest.uproject" BTW, my phone is XiaoMi Mi 2s.

I have successfully packaged a project for Android and installed it onto our Xiaomi Mi 2S. When you're installing on the device, you should either install the APK or the BAT file, depending on which way you are trying to install onto the device. Since you said you've added the PAK file to the device, you should instead add the APK files to the device and install.

Is this the documentation you're using?

Thanks!

Hey Samantha, I mean PAK file went wrong. I installed APK file and it works file. But after I added a box into level, package a PAK file and copy it to sdcard, the error message popped up. Yes, I used that documentation. Thank you.

@Cuoxia

Our Developers are investigating this issue further but we need some additional information from you:

  • Are you installing 2 pak files?

  • Could you provide more detailed reproduction steps?

  • Do you still have your logs files? If so, upload them.

Thanks!

Hey Samantha, I installed just 1 pak file. I reproduced it using third person c++ template and normal patch steps. Can't find log files, sorry :( I'm not working on patch now since my game have't finished yet.

Thank you, I have relayed the information onward.

Cuoxia,

Thank you for your patience.

I've been looking over this issue for a couple of days and I'm running into an error where no matter what platform I build my patch for, it results in an error. I have entered a bug UE-35200 for this and hope to have more information soon.

In the meantime, I have found a few posts that I believe may be helpful with resolving the issue you've ran in to:

Let me know if you've already gotten over this issue. If you did, please let me know what helped.

Thanks!
