Android App Does Not Open

Hello everyone!

I am trying to use my Huawei Acsend G750-U10 for development with Unreal, but when I launch and package a game (FPS Template & Tappy Chicken) it does not open.

I have used this guide: Setting Up Unreal Engine Projects for Android Development | Unreal Engine 5.1 Documentation.

I set-up TADP, and put my device in developer mode and windows reconises it in adb services.
Then I opened UE4 with for example Tappy Chicken, and launched it to my phone. It build successful, and after that I packaged my project and launched the .bat That also worked fine, but when I try to open the app on my phone, the screen goes black and then goes back to my home menu.

I am using windows 8.1 Pro with engine version 4.6.

I hope you guys can help me out with this :slight_smile:

Nope. This does not work for me. Which is a shame :confused:

I would love an official response to this as well. check out my post to see if it helps you at all. Android for distribution fails to load on device - Mobile - Unreal Engine Forums Rather disappointed with epic on this one. I have yet to get a response and I luckily figured out a work around other wise my game would be unplayable! Hopefully they respond to you, if not check out my work around.

Can you upload log? you can got log in your device . You also can get more detail message while launch app on your device by eclipse or vs-ide. Generally, this situation may come from jni or your package name is not the jni needed.so please check your log file for showing more details message.

What? I do not understand what logs you want.

When your app crashed in starting, the engine may not hook any issues. In this situation you need use the eclipse or US-IDE tools gets more detail information when you launch your app. If your environment is ok, you can see your android device in VS after your device was connected to PC platform. So you can see any log of your android output. This log is very helpful for us to solve game crash problem.

I am sorry, but I do not know how to connect my phone to eclipse. I do know what eclipse is, and I do have it downloaded but what does it have to do with unreal engine? Could you maybe explain the process of linking my phone with eclipse, so that it checks for errors on launch?

you open the eclipse on PC platform, and connect your android device to pc. In the eclipse, you can see your device. This is not associate with unreal engine. If you done this, you selected your device on eclipse, and then clear all logs which has been outputted to log panel . Then you launch your app and you can see the all log in log panel. you can filter logs for only read error. So you can see the result from what. Clearly? of course , you also can realize it with VS IDE.
In here , i upload the image which shows you how do i get detail message of launching app from VS-IDE.

This is visual studio, and I am just testing the Tappy Chicken project from Epic Games. I also tried to run the app on a Huawei G700-U10 that my dad has, and that works. But on mine it doesn’t. I suspect that it has something to do with the APK not being compiled correctly for my Phone.

Maybe. But i think you had better get more message from VS.

Hi NeusAap,

Are you still seeing this issue? What do you suspect is wrong with the compile and your phone?

Hello, I do not know what is wrong with it. I do not use the phone I used for this project anymore. Because it simply just did not want to run it. I think the GPU in that phone was just not supported. I now use the Huawei G700 instead of the G750. This one works perfectly. Although, I do not use Unreal anymore at the moment because my DevTeam prefers Unity. So I do not really have this problem anymore.

i also use the huawei ascend g700-u10 and i fix the problem by turning off PhysX related things
phones older than 2014 don’t have support for the unreal engine PhysX
