+# How to build from source
+
+This script has only been tested on Ubuntu 24.04 LTS. **READ ALL THE STEPS BEFORE LAUNCHING THE SCRIPT**.
+
+1. The script will checkout a specific commit hash. If you want a different one, Edit [build.bash](./build.bash) and change `SPECIFIC_REVISION` variable.
+2. You **must** set environment variables `ANDROID_SDK` to point to Android SDK and `JAVA_HOME` to point to the Java installation (for best results, use the one bundled with Android Studio), and `ANDROID_NDK` to a specific NDK version (see Common Errors section).
+   - gradle dropped support for `ANDROID_NDK` environment variable a long time ago, *however* the Gradle scripts in gamesdk check for this variable and re-added the functionality.
+3. You **must edit** [local.properties](./local.properties) to have `sdk.dir` point to your Android SDK (i.e. same as `ANDROID_SDK`), and have `cmake.dir` point to where the CMake included in your Android SDK lives.
+
+This script assumes you already have installed necessary dependencies such as repo, git, the Android SDK and Android Studio.
+
+**Example:**
+
+```bash
+sudo apt install repo ninja-build git
+
+export ANDROID_HOME=/home/matias/Android/Sdk
+export JAVA_HOME=/home/matias/apps/android-studio/jbr
+export ANDROID_NDK=/home/matias/Android/Sdk/ndk/21.4.7075529
+
+./build.bash
+```
+
+## Extracting the files
+
+The files will be generated at `build/package/local/gamesdk.zip`. Decompress it and extract `games-frame-pacing-release.aar`.
+
+The files will be at `games-frame-pacing-release.aar_FILES/prefab/modules/swappy_static`.
+
+Note that the library paths say: `android.arm64-v8a`, `android.x86_64`, etc. **Remove** the `android.` prefix.
+
+# Common Errors
+
+## "NDK not configured"
+
+If you get the following error message:
+
+```
+org.gradle.api.InvalidUserDataException: NDK not configured. Download it with SDK manager. Preferred NDK version is '21.4.7075529'. 
+```
+
+You **must** install NDK version `21.4.7075529` (or whatever number it asks you). It says "preferred" but it's mandatory.
+You may have others NDK versions installed, but the error won't go away until you install the exact version it is asking you.
+
+Use the SDK Manager -> **SDK Tools**:

+
+## Failed to find target with hash string 'android-31'
+
+If you get the error:
+
+```
+Failed to find target with hash string 'android-31' in: /home/matias/Android/Sdk
+```
+
+Then you must install Android API 31 SDK.
+
+Use the SDK Manager -> **SDK Platforms**:
+
+![](Docs/sdk_install.png)
+
+## Failed to find Build Tools revision 30.0.3
+
+Install Build Tools version 30.0.3
+
+Use the SDK Manager -> **SDK Tools**:
+
+![](Docs/build_tools.png)
+
+## Other errors
+
+Pay a lot of attention to the errors, it's very easy to get lost.
+
+**For example all the following errors are completely misleading:**
+
+```
+> Task :buildSrc:compileKotlin
+'compileJava' task (current target is 17) and 'compileKotlin' task (current target is 1.8) jvm target compatibility should be set to the same Java version.
+w: /home/matias/SlowProjects/godot-swappy/build/gamesdk/buildSrc/src/main/java/com/google/androidgamesdk/AarPrefabPatcher.kt: (48, 13): 'createTempDir(String = ..., String? = ..., File? = ...): File' is deprecated. Avoid creating temporary directories in the default temp location with this function due to too wide permissions on the newly created directory. Use kotlin.io.path.createTempDirectory instead.
+w: /home/matias/SlowProjects/godot-swappy/build/gamesdk/buildSrc/src/main/java/com/google/androidgamesdk/BuildInfoFile.kt: (52, 9): Parameter 'nativeLibraries' is never used
+
+> Task :buildSrc:jar
+:jar: No valid plugin descriptors were found in META-INF/gradle-plugins
+
+> Task :buildSrc:compileTestKotlin
+'compileTestJava' task (current target is 17) and 'compileTestKotlin' task (current target is 1.8) jvm target compatibility should be set to the same Java version.
+
+FAILURE: Build failed with an exception.
+```
+
+This could get you completely side-tracked, because if you keep reading, it will tell you the following:
+
+```
+* What went wrong:
+Could not determine the dependencies of task ':games-frame-pacing:verifyReleaseResources'.
+> Failed to find target with hash string 'android-31' in: /home/matias/Android/Sdk
+
+* Try:
+> Run with --stacktrace option to get the stack trace.
+> Run with --info or --debug option to get more log output.
+> Run with --scan to get full insights.
+
+* Get more help at https://help.gradle.org
+
+Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.
+```
+
+AHA! **Failed to find target with hash string 'android-31' in: /home/matias/Android/Sdk**. This is the root of the problem.
+
+In rare cases, the root of the problem may be the first problem to appear, instead of the last one; and in that case you may have to scroll quite a bit.
+
+For example if you force it to build with a newer NDK version than the recommended one, you will get errors C++ about function redeclarations with a different function signature, but at the bottom you will see Java errors that mislead you.
