双守护进程保护程序运行

涉及到服务通信，使用AIDL。

MyProcess.aidl：

package com.study.dn_process.inter;
interface MyProcess{String getProcessName();
}

LocalService：

package com.study.dn_process.service;import android.annotation.SuppressLint;
import android.annotation.TargetApi;
import android.app.Notification;
import android.app.PendingIntent;
import android.app.Service;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Build;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;import com.study.dn_process.R;
import com.study.dn_process.inter.MyProcess;@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public class LocalService extends Service {private MyBinder binder;private MyServiceConnection conn;private PendingIntent pendingIntent;@Overridepublic IBinder onBind(Intent intent) {return binder;}@Overridepublic void onCreate() {super.onCreate();if (binder == null) {binder = new MyBinder();}conn = new MyServiceConnection();}@SuppressWarnings("deprecation")@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {// LocalService.this.startService(new Intent(LocalService.this,// RemoteService.class));// 绑定远程服务this.bindService(new Intent(LocalService.this, RemoteService.class),conn, Context.BIND_IMPORTANT);Notification notification = new Notification(R.drawable.ic_launcher,"服务启动中", System.currentTimeMillis());pendingIntent = PendingIntent.getService(this, 0, intent, 0);notification.setLatestEventInfo(this, "服务", "---", pendingIntent);return START_STICKY;}class MyServiceConnection implements ServiceConnection {@Overridepublic void onServiceConnected(ComponentName name, IBinder service) {Log.e("info", "ServiceConnected");}@SuppressLint("InlinedApi")@Overridepublic void onServiceDisconnected(ComponentName name) {// 重新连接远程服务LocalService.this.startService(new Intent(LocalService.this,RemoteService.class));LocalService.this.bindService(new Intent(LocalService.this,RemoteService.class), conn, Context.BIND_IMPORTANT);}}class MyBinder extends MyProcess.Stub {@Overridepublic String getProcessName() throws RemoteException {return "LocalService";}}
}

RemoteService：

package com.study.dn_process.service;import android.annotation.SuppressLint;
import android.annotation.TargetApi;
import android.app.Notification;
import android.app.PendingIntent;
import android.app.Service;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Build;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;import com.study.dn_process.R;
import com.study.dn_process.inter.MyProcess;@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
public class RemoteService extends Service {private MyBinder binder;private MyServiceConnection conn;private PendingIntent pendingIntent;@Overridepublic IBinder onBind(Intent intent) {return binder;}@Overridepublic void onCreate() {super.onCreate();if (binder == null) {binder = new MyBinder();}conn = new MyServiceConnection();}@SuppressWarnings("deprecation")@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {// RemoteService.this.startService(new Intent(RemoteService.this,// LocalService.class));this.bindService(new Intent(RemoteService.this, LocalService.class),conn, Context.BIND_IMPORTANT);Notification notification = new Notification(R.drawable.ic_launcher,"服务启动中", System.currentTimeMillis());pendingIntent = PendingIntent.getService(this, 0, intent, 0);notification.setLatestEventInfo(this, "服务", "---", pendingIntent);return START_STICKY;}class MyServiceConnection implements ServiceConnection {@Overridepublic void onServiceConnected(ComponentName name, IBinder service) {Log.e("info", "ServiceConnected");}@SuppressLint("InlinedApi")@Overridepublic void onServiceDisconnected(ComponentName name) {RemoteService.this.startService(new Intent(RemoteService.this,LocalService.class));RemoteService.this.bindService(new Intent(RemoteService.this,LocalService.class), conn, Context.BIND_IMPORTANT);}}class MyBinder extends MyProcess.Stub {@Overridepublic String getProcessName() throws RemoteException {return "RemoteService";}}
}

MainActivity：

package com.study.dn_process;import com.study.dn_process.service.LocalService;
import com.study.dn_process.service.RemoteService;import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);this.startService(new Intent(this, LocalService.class));this.startService(new Intent(this, RemoteService.class));}}

tip：清单文件需要注册！
