两个Service之间相互监视的实现，两个service监视

在实际开发中可能需要用到两个Service相互监视的情况，本示例就是实现此功能以作参考。

服务A：

 1 public class ServiceA extends Service {
 2 
 3 
 4     private static final String TAG = ServiceA.class.getSimpleName();
 5     MyBinder mBinder;
 6     MyServiceConnection mServiceConnection;
 7     PendingIntent mPendingIntent;
 8 
 9     @Override
10     public void onCreate() {
11         super.onCreate();
12 
13         if(mBinder==null)
14         {
15             mBinder=new MyBinder();
16         }
17         mServiceConnection=new MyServiceConnection();
18     }
19 
20     @Override
21     public int onStartCommand(Intent intent, int flags, int startId) {
22         ServiceA.this.bindService(new Intent(ServiceA.this,ServiceB.class),mServiceConnection, Context.BIND_IMPORTANT);
23         mPendingIntent=PendingIntent.getService(this,0,intent,0);
24         Notification.Builder builder=new Notification.Builder(this);
25         builder.setTicker("守护服务A启动中")
26                 .setContentText("我是来守护服务B的")
27                 .setContentTitle("守护服务A")
28                 .setSmallIcon(R.mipmap.ic_launcher)
29                 .setContentIntent(mPendingIntent)
30                 .setWhen(System.currentTimeMillis());
31         Notification notification=builder.build();
32 
33         startForeground(startId,notification);
34 
35 
36         return START_STICKY;
37     }
38 
39     @Override
40     public IBinder onBind(Intent intent) {
41         return mBinder;
42     }
43 
44     public class MyBinder extends IBridgeInterface.Stub {
45 
46         @Override
47         public String getName() throws RemoteException {
48             return "name:"+TAG;
49         }
50     }
51 
52     class MyServiceConnection implements ServiceConnection {
53 
54         @Override
55         public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
56             String name=null;
57             try {
58                 name= IBridgeInterface.Stub.asInterface(iBinder).getName();
59             } catch (RemoteException e) {
60                 e.printStackTrace();
61             }
62 
63 
64             Toast.makeText(ServiceA.this,name+"连接成功",Toast.LENGTH_SHORT).show();
65         }
66 
67         @Override
68         public void onServiceDisconnected(ComponentName componentName) {
69             Toast.makeText(ServiceA.this,TAG+"断开连接",Toast.LENGTH_SHORT).show();
70 
71             ServiceA.this.startService(new Intent(ServiceA.this,ServiceB.class));
72 
73             ServiceA.this.bindService(new Intent(ServiceA.this,ServiceB.class),mServiceConnection, Context.BIND_IMPORTANT);
74 
75         }
76     }
77 
78 
79 }

服务B：

 1 public class ServiceB extends Service {
 2 
 3     private static final String TAG = ServiceB.class.getSimpleName();
 4     private PendingIntent mPendingIntent;
 5     private MyBinder mBinder;
 6     private MyServiceConnection mServiceConnection;
 7 
 8     @Override
 9     public IBinder onBind(Intent intent) {
10         return mBinder;
11     }
12 
13     @Override
14     public void onCreate() {
15         super.onCreate();
16         if (mBinder == null) {
17             mBinder = new MyBinder();
18         }
19 
20         mServiceConnection = new MyServiceConnection();
21     }
22 
23     @Override
24     public int onStartCommand(Intent intent, int flags, int startId) {
25         this.bindService(new Intent(ServiceB.this, ServiceA.class), mServiceConnection, Context.BIND_IMPORTANT);
26         mPendingIntent = PendingIntent.getService(this, 0, intent, 0);
27         Notification.Builder builder = new Notification.Builder(this);
28 
29         builder.setTicker("守护服务B启动中")
30                 .setContentText("我是来守护服务A的")
31                 .setContentTitle("守护服务B")
32                 .setSmallIcon(R.mipmap.ic_launcher)
33                 .setContentIntent(mPendingIntent)
34                 .setWhen(System.currentTimeMillis());
35         Notification notification = builder.build();
36         startForeground(startId, notification);
37 
38         retur
