ServiceUtils

The ServiceUtils library is a collection of Java classes to assist with interacting directly with Android System Services using the SystemServiceConnector class. This class exposes a simple API to connect and invoke methods of services without the need to import private classes (such as the "android.os.ServiceManager" class) or generate stub classes to tell the IDE about API details. To achieve this, ServiceUtils makes use of the Reflection API.

Installing

dependencies {
    ...
    compile 'com.github.jakev:android-service-utils:0.0.1'
}

Examples

Using the SystemServiceConnector class is easy: create a new object SystemServiceConnector, passing the service name and Java class name (both of which can be found using the adb shell service list command):

    SystemServiceConnector ssc = new SystemServiceConnector("phone",
            "com.android.internal.telephony.ITelephony");

Next,use the callMethod(...) or callMethod() class to invoke the desired method:

    ssc.callMethod("dial", "123456789");

A ConnectorException will be thrown in error conditions. You can view the system logs to extract additional details.

For a working example of how to use the API, see the included app/ Android application.
