   here is the code i've used:</p>
  
  <p>my Onchange method is calling Correctly and i'm requesting for sync by requestSync but onPerformChange never called, </p>
  
  <pre><code>private class ContentObserverCLS extends ContentObserver {
  
      @Override
      public void onChange(boolean selfChange) {
          super.onChange(selfChange);
  
          final SessionManagement management = new SessionManagement(
                  getApplicationContext());
  
  
              final Account account = new Account(management.getUserDetail()
                      .getUserName().toString(),
                      "com.myapp.account");
  
              final Bundle bundle = new Bundle();
              bundle.putBoolean(ContentResolver.SYNC_EXTRAS_MANUAL, true);
              ContentResolver.requestSync(account,
                      ContactsContract.AUTHORITY, bundle);
          }
      }
  
  }
  
  public static class SyncAdapterImpl extends AbstractThreadedSyncAdapter {
      private final Context mContext;
  
      public SyncAdapterImpl(Context context) {
          super(context, true);
          mContext = context;
      }
  
      @Override
      public void onPerformSync(Account account, Bundle extras,
              String authority, ContentProviderClient provider,
              SyncResult syncResult) {
          //TODO
  
      }
  }

  private static ArrayList&lt;MobileContactInfo&gt; phoneContacts;
  
  public static void run(Context context, ServiceConnection connection) {
  
      Intent i = new Intent(context, ContactsSyncAdapterService.class);
      // Set the general action.
      i.setAction("ACTION_START");
      // Request to start.
      context.startService(i);
  }

      IBinder ret = null;
      ret = sSyncAdapter.getSyncAdapterBinder();
  
      final Handler handler = new Handler();

      getContentResolver().registerContentObserver(

      return ret;
  }
