Error with Android build

xiameishicang · April 23, 2024, 8:25am

Hi, I’m having some problems with cesium-for-unity 1.9.0. I compiled and installed com.cesium.unity according to the developer’s documentation when I packaged the Android APK, and then I got the following error:

An error occurred while building CesiumForUnityNative. See E:\UnityProject\cesium-unity-samples-1.9.0\Packages\com.cesium.unity\native~\build-Android-arm64\build.log for details. The command-line was:
cmake --build “E:\UnityProject\cesium-unity-samples-1.9.0\Packages\com.cesium.unity\native~\build-Android-arm64” --config Debug --parallel 21 --target install
UnityEngine.Debug:LogError (object)

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

CommandInvokationFailure: Gradle build failed.
C:\Program Files\Unity\Hub\Editor\2023.2.17f1c1\Editor\Data\PlaybackEngines\AndroidPlayer\OpenJDK\bin\java.exe -classpath “C:\Program Files\Unity\Hub\Editor\2023.2.17f1c1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-7.6.jar” org.gradle.launcher.GradleMain “-Dorg.gradle.jvmargs=-Xmx4096m” “assembleDebug”

And when I rolled back to 1.8.0, I can package the APK normally.
I would like to ask what is the reason for this? Is there any solution for this? Will it be fixed in subsequent releases?

Hi @xiameishicang,

Thanks for alerting us to this issue! This certainly wasn’t intentional, and in fact we haven’t seen this before. To keep track of this, I’ve written up an issue on Github so we can give updates on our progress.

I see that you’re using Unity 2023.2.17f and packaging from cesium-unity-samples. Just to get more information, did you modify the sample levels in any way? Are there specific scenes that you’re including with the build?

Unity: 2023.2.17f1c1
Installing Android components with unity hub.
I wrote my own script that loads my own graphic source, and partially changed the source code to fit the script.
Here is the log message mentioned in the error:

Thanks @xiameishicang for posting more information. It looks like this is the real error in that log:

make[2]: *** No rule to make target ‘extern/cesium-native/extern/draco/CMakeFiles/draco_compression_attributes_pred_schemes_enc.dir/4903a2f1d67bacb7cbad22462a10a95f/prediction_scheme_encoder_factory.cc.o’, needed by ‘extern/cesium-native/extern/draco/libdracod.a’. Stop.

We recently updated the version of Draco that we use in Cesium Native, so this may be related to those changes. I’ve made a note of it in the issue I opened. We’ll investigate and post updates as soon as we are able

Hi @xiameishicang,

One of my teammates looked over your log and saw this error:

CMake Warning in extern/cesium-native/extern/draco/CMakeLists.txt:
The object file directory

E:/UnityProject/cesium-unity-samples-1.9.0/Packages/com.cesium.unity/native~/build-Android-arm64/extern/cesium-native/extern/draco/CMakeFiles/draco_compression_attributes_pred_schemes_enc.dir/
has 192 characters. The maximum full path to an object file is 250
characters (see CMAKE_OBJECT_PATH_MAX). Object file

4903a2f1d67bacb7cbad22462a10a95f/prediction_scheme_encoder_factory.cc.o
cannot be safely placed under this directory. The build may not work
correctly.

This can happen when you don’t have long paths enabled on your machine. Can you verify that this setting is enabled?

You may also want to shorten the URL of your project itself. So for example, placing it at E:/a/cesium-unity-samples, or something similar.

Let us know if that helps your build to succeed!
