[android help] How to know which jar file of android sdk contains the class I need

How to know which jar file of android sdk contains the class I need

I want to recreate android uiautomator.jar (not the whole android framework) in eclipse from its source code, and need to:

import android.accessibilityservice.UiTestAutomationBridge; 
import android.os.SystemService;

but saw the following errors:

package android.accessibilityservice does not exist
package android.os does not exist

I am using android sdk-17. From the source code coming with the sdk, I can see that the packages do exist, they are under sources/android-17/android, and I can see the java source files are there.

My build path contains only android.jar, obviously it does not includes these packages. Is there a way to know which jar I should include? I understand the whole android framework needs to be compiled in Linux environment. Is it possible to compile uiautomator using Eclipse. It is only a jar file used for UI tetsing. Thanks.
