Hi. So at first it WAS working on android but it was skipping the menu level (I had default game map set correctly, I don’t know why it was happening, on windows everything was correct)
Then it suddenly after a few build it stopped to launch at all. Wtf? It sill launches on windows
Hey, you posted this question like 5 times, thats kind of not cool.’
I’m not an expert but I’ve had many issues with UE4 too so maybe I can help. Can I start by asking, is the launch to device successful or is it failing? If failing then you should upload the log so that someone who understands all that gibberish take a look at it.
Hi, the thing is that I am not having issues with launching to device. I have issues launching on device. Thanks I will lok into it
Yeah, I asked 5 times because no was going to answer. Can’t make a launch to device since my phone won’t allow usb debugging. Launch on windows is ok. Which logs should I look for? Build? Thanks
I’m a bit confused, your main question says that you are having issues with launching to your device, but now you are saying that the device isn’t working properly? Wouldn’t that be the issue then or am I missing something?
Also, when you launch your project, it creates a log, which you can see by opening up the outputlog while in engine. A copy of it can be found in unreal projects/[your project]/saved/logs
Oh, ok. The way you worded that was very confusing.
So to clarify, you’re packaging your game, moving it over to your phone, installing it and then trying to play it. And your issue is that the game doesn’t load anymore when on your device, right?
Alternatively, while in engine, go to windows → project launcher and use that to launch your game to windows instead. Gives you real time feedback like PIE
Hi, sorry for not being clear and sorry for the late reply - just came home now.
So, yes. I package game, move it to my phone. Installation goes well. I launch it, it shows the splash screen and minimizes(it’s still in the processes). At first it was just skipping the meni and now it won’t let me play at all 
Then definitely try using the project launch, like I mentioned above, and launch to Windows. It’ll simulate what your phone does and it’ll give you instant feedback about what your issue is.
Hi. I tried but I don’t understand what you mean by getting live feedback. I looked at blueprints and nothing is firing, nothing showing. I launched it Windows and is fine. Then I packaged the game again, moved to my phone and it won;t launch again. Please halp
When you launch to windows, there no output log that runs while your game is running in the same fashion as play in editor? Because that’s what I mean by live feedback.
Just want to clarify, are you launching to windows from the main editor toolbar or are you going to the windows tab on the top left, clicking on Project Launcher and then launching to windows from there.
Also, when you are there, make sure that the cook settings says ‘By the book’. If it says ‘On the fly’ then change it to ‘by the book’.
