目标：在PackageManagerService加入方法public String getHello();
第一步：在IPackageManager.aidl增加getHello()方法声明
interface IPackageManager {
PackageInfo getPackageInfo(String packageName, int flags);
int getPackageUid(String packageName);
int[] getPackageGids(String packageName);
String[] currentToCanonicalPackageNames(in String[] names);
String[] canonicalToCurrentPackageNames(in String[] names);
PermissionInfo getPermissionInfo(String name, int flags);
List<PermissionInfo> queryPermissionsByGroup(String group, int flags);
PermissionGroupInfo getPermissionGroupInfo(String name, int flags);
List<PermissionGroupInfo> getAllPermissionGroups(int flags);
ApplicationInfo getApplicationInfo(String packageName, int flags);
ActivityInfo getActivityInfo(in ComponentName className, int flags);
ActivityInfo getReceiverInfo(in ComponentName className, int flags);
.
.
.
.
.
.
String getHello();
}
public abstract class PackageManager {
/**
* This exception is thrown when a given package, application, or component
* name can not be found.
*/
public static class NameNotFoundException extends AndroidException {
public NameNotFoundException() {

public NameNotFoundException(String name) {
super(name);
}
}
