I am quite new to the android platform. I want to export my service to be publicly used. I find something on developer doc
android:exported
Whether or not
You can will find that the sample applications SampleSyncAdapter, CubeLiveWallpaper, and VoiceRecognitionService (new in level 8) all export services for public use. You can look through your sdk's samples/ directory. Eclipse can create a new project using the existing samples (from the File/New/Android Project dialog).
