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"

[Help] App force closes and says it has Stopped when implementing "Show external login UI" node?

I packedged the project and uploaded the apk in the google play store in alpha testing. I updated my app on my phone and when i opened it it gives me, "Unfortunately, has stopped.'' And also it says in the notifications that my app is, 'looking for resources to download''. Like i don't what that means and i don't know whats the problem?

Hey Spookey0188,

I was unsuccessful in replicating this in a First Person Blueprint project on the Nexus 5. Could you please give me more information about your project, your device and whether or not you've been able to replicate this error? Do you have any logs from your device that I could review?

If you're not sure how to obtain logs on your Android device, please go to: C:\NVPACK\android-sdk-windows\tools and open up 'Monitor.bat' and obtain logs from there. You will have to select the logs you want to save otherwise a blank log will be saved.

The app works fine when I package it and install it through the bat file. Everything works even google services. Howevr whenI install it through play store in alpha testing it gives me this error debug log

Did you try as Chris Babcock suggested and change the LicenseChecker.java within the Engine directory and not your project? Are these the errors that show up after you've done as suggested?

If so, could you please provide us with a full output log from the device? You should be able to get the logs by going to: C:\NVPACK\android-sdk-windows\tools and running Monitor.bat

Hey i did what chris asked and i packaged the app and uploaded to the play store In alpha testing. So when i download it i don't get the force closing error or such, but instead now i get an XAPK validation failed error? I posted this response more detailed in the other thread where i asked this question which i linked above. If you know how to fix this XAPK validation failed error that would be awsome. Thanks!

Please turn on the package data in APK. It's under Android Settings in Project Settings. Once it's packaged if it's equal or less than 100 mb then you can upload it onto GooglePlay without the OBB.

Hey! I finally got it to work. The reason it said XAPK file validation failed is because when I package the app with an .OBB file. I forgot to upload the .OBB as an expansion file after I uploaded the APK. Which is my fault my fault in my case.
