Android setup documentation

[Gibbz]

I'm working on adding this to my android project. The project is using xbuild and slint, which uses and android activity crate ( https://github.com/slint-ui/slint/tree/master/internal/backends/android-activity ).

Ive completed the steps below:

<cd to Projects folder>
git clone https://github.com/deviceplug/jni-utils-rs.git
cd jni-utils-rs
cargo build --features=build-java-support
jar files located in /target/debug/java/libs

cd ..
git clone https://github.com/deviceplug/btleplug.git
cd btleplug/src/droidplug/java
edit build.gradle, comment and replace:
dependencies {
    implementation files('/home/bronson/Projects/jni-utils-rs/target/debug/java/libs/jni-utils-0.1.1-SNAPSHOT.jar')
}
./gradlew build 
btleplug/src/droidplug/java/build/outputs/aar/

This gets step 1 complete, and most of step 2...

A quick overview of the build process:

1  For java, you will need the java portion of [jni-utils-rs](https://github.com/deviceplug/jni-utils-rs) available either in a Maven repository or locally (if locally, you'll need to check out btleplug and change the gradle file).
2.  Either build the java portion of btleplug, in the src/droidplug/java directory, using the included gradle files, and them to a Maven repo, or have the Java portion of your android app point to that as a local implementation.
3.  For Rust, the build should go as normal, though we recommend using cargo-ndk to build. Output the jniLibs and make sure they end up in the right place in your app.

But how do i do step 2? have the Java portion of your android app point to that as a local implementation when slint takes care of this all for me?

Do I need to modify the slint source code to add the btleplug stuff? Or load that through rust?

They have no gradle files, no mainactivity... do I modify the java?
