WHY build failed?

anonymous_user_2635691e1 · November 8, 2015, 7:24am

I tried to package the 3rd-person-example android project (https://docs.unrealengine.com/latest/INT/Platforms/Android/GettingStarted/3/index.html) but I kept getting build-failed which is frustrating. I hope somebody might know what is the issue here… Thanks in advance!

1 I am using windows7-64version, UE4.9.2. I installed jdk1.7+sdk+apache ant+ndk with androidWorks1R1(that comes with UE 4.9.2). For no reason at all androidWorks could not download Nsight Tegra Package and I happened to learn that Nsight is not mandatory for non-C++ project, so I just skipped Nsight. Is it due to missing Nsight? IF yes, do I need visual studio?

2 I use android studio and had jdk1.8 and android sdk previously installed on my machine. i checked the system enviroment variables after androidWorks1R1 installation that all enviroment variables are pointing to the stuff installed by androidWorks1R1. So i guess the previous jdk and sdk should not be an issue here??—is it?

3 I tried to play with the minimum/target sdk version, 9/16/19, but it doesn’t help.

4 below is how the look like.

I do not remember where it is, you need to find that other log yourself.
RunUAT runs some commandline tool that creates log, in that log you have more information.

This RunUAT error usually happens when you have unfinished installation of android sdk, sometimes, name of project matters, you need to name apk in properties in certain way. But I would first check that other log, and check android SDK installation.

Hey ,

If you haven’t already, please upload a full .txt version of your output to an AnswerHub post. We’ll be able to figure out what’s going on with your packaging process. Include a screenshot of your Android SDK as well.

Thank you!

Dear all: Thanks for your suggestions.

It seems the previously installed android enviroment(JDK+SDK+android studio) had some impact .

I deleted all JDK and SDK and reinstalled UE and androidWorks1R1(full installation). It is working fine now.
