why Build failed on UE4.9.2

nanyi545 · November 8, 2015, 7:00am

I tried to package the 3rd-person-example project (https://docs.unrealengine.com/latest/INT/Platforms/Android/GettingStarted/3/index.html) but I kep getting below error logs. I hope I could get some hint in the forum and I would like to thank you guys in advance.

I installed jdk1.7/sdk/apache ant/ndk using AndroidWorks-1R1 (that comes with UE4.9.2). For no reasone at all, the Nsight Tegra Package just could not be downloaded, so I skipped it. And I happend to learn from this thread(https://forums.unrealengine.com/showthread.php?90391-Dev-for-Android-Step-by-Step) that Nsight Tegra Package is not mandatory for non-C++project.
I had android studio previously on my machine(windows 7, 64version), so I already have jdk1.8 and sdk. But I checked the system enviroment variables after the installation of AndroidWorks, all enviroment variables are pointing to the stuff installed by AndroidWorks. So I believe the older JDK and sdk should not be an issue???–is this correct or not?
I tried to play with the minimum/target sdk version 9/16/19… doesn’t work.

Hi nanyi545,

javac is used to compile the java code by Ant. It looks like you have a mismatch of the jdk for the tools runtime. Check you are using java 1.7 as JAVA_HOME, ANT_HOME points to the apache-ant-1.8.2 and ANDROID_HOME points to the android-sdk-windows. All three should be in the NVPACK installed with AndroidWorks.

Hi Chris, you are probably right.

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