我已經創建了一個簡單的服務，它將增加一個計數器並記錄它。服務啓動多次後會發生什麼
public class AudioService extends Service {
int i=0;
private final IAudioInterface.Stub mBinder = new IAudioInterface.Stub() {
public int getI()
{
return i;
}
};
@Override
public IBinder onBind(Intent intent) {
Log.d("onBind from service","****");
return mBinder;
}
@Override
public void onCreate() {
super.onCreate();
Log.d("onCreate from service","***");
Log.d("i=","="+i);
i=i+1;
}
@Override
public void onDestroy() {
super.onDestroy();
Log.d("OnDestroy Called from service","***");
}
public void onStartCommand(Intent intent, int startId) {
super.onStart(intent, startId);
Log.d("onStartCommand from service","***");
}
@Override
public boolean onUnbind(Intent intent) {
Log.d("onUnbind from service","***");
return super.onUnbind(intent);
}
我正在遞增他服務oncreate方法中的i值。
客戶端活動被如下所示
public class AidlInterfaceServiceActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
private static final String TAG = "Audio:Service";
IAudioInterface mService = null;
boolean connected = false;
ServiceConnection mConnection = new ServiceConnection(){
public void onServiceConnected(ComponentName arg0, IBinder service) {
// TODO Auto-generated method stub
connected = true;
Log.d("Service connected","**");
mService = IAudioInterface.Stub.asInterface(service);
try {
Log.d("i from client","="+mService.getI());
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void onServiceDisconnected(ComponentName arg0) {
// TODO Auto-generated method stub
Log.i(TAG, "Service disConnected");
connected = false;
mService= null;
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.d("on created ","**********");
Intent music = new Intent();
music.setClass(this,AudioService.class);
startService(music);
bindService(music, mConnection, Context.BIND_AUTO_CREATE);
}
的AIDL文件是如下
interface IAudioInterface
{
int getI();
}
的問題是當我每次運行客戶端的活動i的值是「0」 。 我的價值沒有增加。
我有這些疑問。
1.服務多次啓動時會發生什麼情況。
2.當服務被限制多次時會發生什麼。
3.多次啓動時，服務類中的數據成員會發生什麼情況？這些數據成員是否被重新初始化？
我真的很困惑..任何一個請幫忙。
