ya im trying to download a simple m6.004 editor with the android apk jdk and sdk packs so i can use the 3d rendering function to create an app. ive never done theis and its been almost a week nothing will load concurrently and i still cant see my device . it keeps taking me in circles im really starting to get frustrated
Well, we can only help if you describe the problem precisely. We can’t tell whether installing the Android module fails, or making a build fails, or if you can’t deploy to the device (seems most likely), or whether there is a runtime failure.
If the Android device doesn’t show up ensure it has Developer Mode enabled. You’ll find Android specific setup, build and debug workflows here.
If there are errors, refer to the log files (Hub, Editor, or Player - based on where the issue occurs) and post them here.
How to troubleshoot build failures:
Obviously, if there is actionable data, clues or information within any of the errors, fix those problems. Each error entry may have more information than can fit in the console log so select each error and read the expanded view below it.
If that gives you nothing worthwhile (look to Google! You’re never the first one!), then…
First, make a blank project with a single blank scene and prove that it builds successfully.
If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.
Until you can build a blank project to the target platform, don’t fiddle with anything else.
Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.
Most often things that prevent building are misconfigured or incorrectly-installed or incompatible third-party libraries such as Firebase or AdMob or IronSource.
Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.
It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.
Android build not building:
Circa July 2022 here have been reports of Unity’s installer failing to install the Android Tools.
Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022 (edited on August 23, 2023 to include Android SDK 33…) (and again for SDK34):
And for Android SDK35, my own experiences and success:
After the Unity-CVE incident I installed Unity2022.3.62f2 and also Android SDK36 and … IT JUST WORKED! I did remove all previous Android SDKs before doing that though.
Android Gradle errors and other related stuff:
