Encountering an error when opening a project with Gradle on Android Studio

[lizbzlx]

I just reinstalled Axmol and today I'm having trouble syncing Gradle.

Normally, I don't encounter this problem, but after adding __1K_CMAKE_VERSION=3.31.5 to the gradle.properties file, the syncing was complete.

Does anyone know why it's no longer working as before and why I had to add this to the gradle.properties file?

Which version of Android Studio?

Using Android Studio 2025.2.3, and a new Axmol project created with Axmol 2.11.2, results in a successful build. The CMake version installed is 4.2.0, and no files were edited at all after creating the new project.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 10.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/9.2.1/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

The axmol -p android -a arm64 builds it in the console. You don't need to run it if you're planning on building in Android Studio.

Try this test to verify that it works:

1. Download the latest version of CMake from here and install it: https://cmake.org/download/ (if you're on Windows, download the "Windows x64 Installer" version)
2. Create a new project via: axmol new -p com.axmol.test -d . -l cpp test
3. Open Android Studio, then inside it open the project folder test/proj.android/
4. Build it

Usually, I wouldn't download cMake from the website but install it directly from the SDK Manager in Android Studio. Then I would simply copy the NDK from 'axmol-2.11.2/tools/external/adt/sdk/ndk' to '/Users/xxx/Library/Android/sdk/ndk/'. After that, I would open proj.android directly from Android Studio, and it would build successfully. But now, after trying your method, I'm forced to install CMake manually.

I've installed it this way a long time ago, many times with various Axmol versions over the past year, and haven't encountered any problems until today.

Here are the steps I used to follow:

1. Install PowerShell, then access the axmol-2.11.2 folder and use the command "pwsh setup.ps1".
2. After that, I create a new Axmol project with the command "axmol new test -l cpp -p com.axmol.test".
3. Access the "test" project just created from Axmol.
4. Use the command "axmol -p android -a arm64" to get the ndk folder.
5. Copy the ndk folder from "axmol-2.11.2/tools/external/adt/sdk/ndk" to "/Users/xxx/Library/Android/sdk/ndk/" (Android SDK Location).
6. Install. CMake 3.31.5 from Android Studio SDK Manager
7. Open proj.android from Android Studio and wait for the build

Installing CMake from within the Android Studio SDK Manager is just a convenience, and it really does not matter how it is installed. What matters is having the version required by Axmol.

Now, regarding the NDK, you do not necessarily need to use the NDK that is downloaded by Axmol. In your project, you will see a file named .axproj, and in there you can set whichever NDK version you want to use, such as any of the NDKs you can download via the SDK manager.

For example, if you want to use NDK r27c, then add this line to the .axproj file in your project:
ndk=r27c+

NDK r27c can be downloaded in the SDK manager. It is version number 27.2.12479018:

As an example of the full version to release version mappings, you can check these websites:
https://github.com/android/ndk/releases
https://github.com/android/ndk/wiki/Unsupported-Downloads

The default used in Axmol is r23d, which if I remember correctly is an unreleased version, and the lowest version that has 16KB page size support.

5. Copy the ndk folder from "axmol-2.11.2/tools/external/adt/sdk/ndk" to "/Users/xxx/Library/Android/sdk/ndk/" (Android SDK Location).

I just did a quick test, and if you run axmol build -p android -f -u -c in the root of your project directory, it will download NDK r23d, and extract it into the correct directory, so you shouldn't need to manually copy it across. This is on Windows, with the environment variables set to point to the Android SDK folder. I'm not sure if it also does this automatically on other platforms (such as MacOS or Linux). If it should be doing it automatically, but it is not, then check to see if you're missing the relevant environment variables (ANDROID_HOME and ANDROID_SDK_ROOT) that point to the root of the Android SDK directory.

For Android Studio, a preinstalled cmake-4.2.0+ should in system env var: PATH
