# Split Install Service

The Split Install Service is a service run as system uid and responsible

for installing a split apk with the hidden `PackageManager.INSTALL_DONT_KILL_APP`

flag. 

## Build

To use the service, add into your project the jar built with the `mm splitinstall-lib` AOSP 

build system command.

## Usage

Then, a client can bind to it with the following:

```kotlin

val intent = Intent().apply {

    component = SplitInstall.SPLIT_INSTALL_SYSTEM_SERVICE

}

bindService(intent, serviceConnection, BIND_AUTO_CREATE)

```

Then, install a split apk:

```kotlin

service.installSplitModule("fake.package.name", "pathToSplitApk")

```

    name: "splitinstall-lib",

    sdk_version: "current",

    srcs: [

    "java/**/*.java",

	"aidl/**/*.aidl",

    ],

    aidl: {

	local_include_dirs: [

	    "aidl/",

    },

}
