Quad bluetooth

Code from "How to write Java with miniquad" tutorial. Showcases miniquad<->java interop. More of a Java native plugin example than a real usable crate!

How to use

• Add a "quad-bt" crate as a dependency to Cargo.toml:

[dependencies]
quad-bt = { path = "../quad-bt" } # functionality of example-android-bluetooth would probably be not sufficient, so local copy for local hacks is preferable!

• Add a required bluetooth metadata to Cargo.toml:

[[package.metadata.android.permission]]
name = "android.permission.BLUETOOTH"
max_sdk_version = 30

[[package.metadata.android.permission]]
name = "android.permission.BLUETOOTH_ADMIN"

[[package.metadata.android.permission]]
name = "android.permission.ACCESS_FINE_LOCATION"

[[package.metadata.android.permission]]
name = "android.permission.BLUETOOTH_SCAN"

[[package.metadata.android.permission]]
name = "android.permission.BLUETOOTH_CONNECT"

• Init a BluetoothAdapter in the rust code:

    let mut adapter = bt::Adapter::new().unwrap();

    ...
