Specify that Vulkan 1.1.0 is used if supported.
Remove explicit requirement of OpenGL ES 3.0 as OpenGL ES 1.0 is also supported as fallback and the client should pick the highest supported version.
Restarting the client previously did not work, as the `shell_execute` function on Android uses `fork` which is not supported.
Now, the client is restarted by using an Android intent to restart the main activity. This is triggered by sending a user-defined message from the native code to the SDL main activity thread.
Split the user storage location and the data folder in the app specific external storage in the folders `data` and `user` instead of writing the user setting directly to the external storage.
Remove unnecessary storage permissions. The client only accesses files in its own external storage location, hence these permissions are not necessary for Android API 19 and higher, which is always given as we only target API 19 and higher.
Only unpack changed assets when their hash in the integrity index is different instead of unpacking all assets again, so the app starts faster after updates. Avoid unpacking the entire integrity index file unless it changed, by initially reading only the first hash directly from the asset, so the app starts faster when the data is up-to-date.
Add error handling for external storage not being accessible and other I/O errors during unpacking of assets.
Add `android_main.h` header to export the `InitAndroid` function and potentially other functions in the future. The `extern "C"` and `__attribute__((visibility("default")))` attributes seem to be unnecessary, as this function is only called directly from the native code like many other functions without these attributes.
Initialize the Android storage after the loggers, so the log message are printed properly.
Add documentation for the use of `std::exit` on Android, which is used to forcefully terminate the entire process, to ensure that static variables will be initialized correctly when the app is started again after quitting. Returning from the main function is not enough, as this only results in the native thread terminating, but the Java thread will continue. Java does not support unloading libraries once they have been loaded, so all static variables will not have their expected initial values anymore when the app is started again after quitting.
Use `fs_chdir` and `fs_makedir` instead of `chdir` and `mkdir`.
SDK 19 is the lowest API level support by SDL2 because it is the lowest API level supported by the latest NDK toolchain. According to https://www.composables.com/tools/distribution-chart this should cover virtually all Android devices.
The dependencies on Kotlin and various `androidx`-Packages were entirely unnecessary and can be removed.
Abort the Android CMake build immediately if any of the command line arguments is not specified, instead of assuming default values.
Add more log messages for different build steps to improve progress reporting and improve the existing log messages.
Improve and fix colors of log messages. Previously, some log message colors were not terminated properly, causing the output color of subsequent commands to change.
Avoid some error messages when the build script is executed for the first time, i.e. when cleanup of the previous build is not necessary because the files do not exist yet.
Make some related variable names more readable by removing the unnecessary underscore and `DEFAULT` prefixes.
Abort the build script when the CMake build fails for any of the selected architectures. Previously, the build may have continued and caused an APK without the respective library files to be built.
SDL automatically loads the libraries specified in the array returned by the `getLibraries` method, so loading it manually is unnecessary. SDL also has additional error handling to quit the app with an appropriate error message popup if the library could not be loaded, which was not handled previously.
Ensure that the main game library is copied successfully. Remove unnecessary copies of library files that do not exist and are unused, which were causing error messages during the build.
Extract `build_gradle` function to reduce duplicate code for running the Gradle build. Remove the initial invocation of Gradle without a build target, which has no effect and was causing an error message during the build.
Parse `GAME_RELEASE_VERSION` and `DDNET_VERSION_NUMBER` definitions from `src/game/version.h` by default, so specifying a version manually is usually not necessary.
Upgrade to Gradle 8.5 and Gradle Plugin 8.3.0 for compatibility with Java 21. Explicity set Java version 21 in `build.gradle`. Increment compile and target SDK version to 34 accordingly.
Remove the explicitly defined, obsolete `buildToolsVersion` property in `build.gradle`, as it is now automatically derived by Gradle.
Replace the deprecated property `android:extractNativeLibs` in `AndroidMainfest.xml` with `useLegacyPackaging` in `build.gradle`.
Replace the deprecated package definition `package="tw.DDNet"` in `AndroidMainfest.xml` with `namespace("tw.DDNet")` in `build.gradle`.
Add the required property `android:exported="true"` to the main activity in `AndroidMainfest.xml`.
Use [cargo-ndk](https://github.com/bbqsrc/cargo-ndk) to configure cargo for building with the Android NDK. The output of `cargo ndk` is written to a subfolder for the target triplet, which cannot be changed by parameter. Therefore, the `CARGO_BUILD_DIR` is changed to this subfolder for the Android build, so the build process can find the output.
Use `$HOME` instead of `~` because cargo-ndk cannot correctly access the folder otherwise (will fail with error message indicating it could not determine the NDK version).
Add `DDNET_TEST_NO_LINK=ON` CMake argument, to fix Rust linking errors with tests.
Add additional CMake arguments to specify system name, API version and NDK location. Upgrade to Android API 34.
Use `nproc` instead of `32` threads for building.
Always force landscape orientation to be used for the game on Android.
Hide the title bar so it is not shown when starting the game. There is also a bug with SDL currently that leads to the title bar and status bar being shown permanently after minimizing and reopening the app, which is alleviated by hiding the title bar.
