Bevy in App

Integrate the Bevy engine into existing iOS | Android apps.

If you want to add a mini-game to an existing app, or implement some dynamic UI components, charts ..., or just want to take advantage of the Motion Sensors on your phone for some cool gameplay, you can't use WinitPlugin. Because winit will take over the entire app initialization process and windowing, but we need to create bevy::App in an existing app instance, and we may also want bevy::App to run in an iOS UIView or Android SurfaceView of any size.

This repository implements such a scenario and uses the phone's motion sensor to play breakout mini-games.

Screenshot

iOS

# Add iOS target
rustup target add aarch64-apple-ios

# Build for iOS target
sh ./ios_build.sh --release

Then, Open iOS/bevy_in_iOS.xcodeproj with Xcode，connect an iOS device and run.

Android

Set up Android environment

Assuming your computer already has Android Studio installed, go to Android Studio > Tools > SDK Manager > Android SDK > SDK Tools. Check the following options for installation and click OK.

Android SDK Build-Tools
Android SDK Command-line Tools
NDK(Side by side)

Then, set two following environment variables:

export ANDROID_SDK_ROOT=$HOME/Library/Android/sdk
# Replace the NDK version number with the version you installed
export NDK_HOME=$ANDROID_SDK_ROOT/ndk/23.1.7779620

Add build targets

# Since simulator and virtual devices only support GLES,
# `x86_64-linux-android` and `i686-linux-android` targets are not necessary
rustup target add aarch64-linux-android

Build

# Install cargo-so subcommand
cargo install cargo-so

# Build
sh ./android_build.sh --release

This is great work!

You've put a ton of effort into this repo and it looks really great. Many thanks for making it public!

Running multiple instances in different activities

Hi there! Thankyou for making such an amazing interface for integrating bevy inside an Android/iOS app.

I was trying to run two different games in different Activities and wanted to switch between them on click of an button.
The first game runs fine however while switching to another activity I get some error related to init_ndk_context method.

I have confirmed that both the generated .so files of the games are valid and they do run when added individually.

here are the error logs:

Any idea why it is happening?

安卓后台之后会导致panic

老师你好
我在运行项目时发现这样的问题
在将app切至后台之后再切出来会崩，问题在于多次初始化context，在将初始化移至init块之后避免了这个问题，但是仍然会多次实例化bevy
ps. 我并不懂安卓，因为想把bevy塞进app才开始研究

根据描述，本案例是作为开屏小游戏
我这边是想把bevy作为主要内容，所以出现了此问题
请老师指点
