Can't start game for android

Made a new project for “Mobile/Phone”, scalable 2d/3d and no starting assets. The template was the blank one. When trying to launch the game on my phone, it fails. This is the log:

Hello ,

Could you post the full log file? It doesn’t seem like the main error message is here. The messages stated here are mainly saying that it failed and aren’t really giving any details as to why.

Here it is: http:///tCkFXkm5

Sorry, it was too large for this textbox so I had to use pastebin.

It seems like another user who was having this issue fixed it by running the editor (UE4Editor.exe) as an Administrator prior to packaging. You can see his post here:

Could you try this and see if it is able to solve the issue?

Hello, sorry for late reply. I tried to launch the UE3editor.exe as administrator and it still doesn’t work.

So that we can see if this is related only to the android/mobile parts of the building process, can you try packaging for Windows to see if that will complete correctly? If so, at least we know what kind of errors to look for. If not, please upload the new logs. Pastebin is fine if it’s too large.

Hello, it worked for Windows, but I have reinstalled my whole windows now (mainly because the reinstall I did a few days ago was bugged…)

I reinstalled everything for the android development and now it works. I think it was something wrong with the Android SDK.

Anyway, thanks for the help!
