我有这个描述服务的代码:

public class navigation_web extends Service {

    Context context;

    public void navigation() {
        Cursor mCur = getContentResolver().query(Browser.BOOKMARKS_URI,
            Browser.HISTORY_PROJECTION, null, null, null);
        mCur.moveToFirst();
        if (mCur.moveToFirst() && mCur.getCount() > 0) {
            while (mCur.isAfterLast() == false) {
                Log.v("titleIdx",
                    mCur.getString(Browser.HISTORY_PROJECTION_TITLE_INDEX));
                Log.v("urlIdx",
                    mCur.getString(Browser.HISTORY_PROJECTION_URL_INDEX));
                mCur.moveToNext();
            }
        }
        // Browser.clearSearches(getContentResolver());
    }

    public void onCreate() {
        // Browser.clearHistory(getContentResolver());
        // Browser.clearSearches(getContentResolver());
        navigation();
        // super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    @Override
    public …

表现：

 <service android:name="com.example.MainService" android:process=":main_service"/>

尝试在活动中绑定服务：

public class MainActivity extends Activity {
    MainService mMainService;

    private boolean mBound;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        bindService(intentForMainService, mConnection, Context.BIND_AUTO_CREATE)
    }

    private ServiceConnection mConnection = new ServiceConnection() {
        public void onServiceConnected(ComponentName className,
                                       IBinder service) {
            MainService.MainServiceBinder binder = (MainService.MainServiceBinder) service;//HERE IS EXCEPTION
            mMainService = (MainService) binder.getService();
            mBound = true;
        }

        public void onServiceDisconnected(ComponentName className) {
            mMainService = null;
            mBound = false;
        }
    };

    @Override
    protected void onStop() {
        doUnbindService();
        super.onStop();
    }

    void doUnbindService() {
        if …
