两个服务的方式实现双进程守护

其实双进程守护，保证我们的应用不会被安全软件杀死，的关键在于我们使用了两个进程，并且是他们是相互绑定的，但是测试发现这种做法，对于小米手机来说，并不起作用。我听说有人使用同步数据的方式来唤醒死掉的进程，或者是使用NDK方式来保护我们的应用，这两种方式，下次再分享。

远程服务

package com.example.mypc.doubleprocess;

import android.app.Service;

import android.content.ComponentName;

import android.content.Context;

import android.content.Intent;

import android.content.ServiceConnection;

import android.os.Binder;

import android.os.IBinder;

import android.support.annotation.Nullable;

import android.util.Log;

import android.widget.Toast;

/**

* Created by MyPC on 2016/10/9.

*/

public class RemoteService extends Service {

private Binder mBinder;
private MyConn mConn;
@Nullable
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}

@Override
public void onCreate() {
mBinder=new MyBinder();
if(mConn==null){
mConn=new MyConn();
}
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
//第一次绑定对方。
RemoteService.this.bindService(new Intent(this,LocalService.class),mConn,BIND_IMPORTANT);

return super.onStartCommand(intent, flags, startId);
}

class  MyBinder extends IProcessService.Stub{

public String getServiceName(){
return  "RemoteService";
}
}

class  MyConn implements ServiceConnection{

@Override
public void onServiceConnected(ComponentName name, IBinder service) {
Log.i("TAG","远程链接本地服务成功");
Toast.makeText(RemoteService.this,"链接本地服务成功",Toast.LENGTH_LONG).show();

}

@Override
public void onServiceDisconnected(ComponentName name) {
//对方（localService）被干掉了
Log.i("TAG","localService服务被杀");
Toast.makeText(RemoteService.this,"localService服务被杀",Toast.LENGTH_LONG).show();
//启动对方（对方会走onStart绑定我）
RemoteService.this.startService(new Intent(RemoteService.this,LocalService.class));
//绑定对方（我再绑定对方）
RemoteService.this.bindService(new Intent(RemoteService.this,LocalService.class),mConn, Context.BIND_IMPORTANT);
}
}

}

本地服务

package com.example.mypc.doubleprocess;

import android.app.Service;

import android.content.ServiceConnection;

impor

t android.os.IBinder;

import android.support.annotation.Nullable;

import android.util.Log;

import android.widget.Toast;

/**

* Created by MyPC on 2016/10/9.

*/

public class LocalService extends Service {

private Binder mBinder;

private MyConn mConn;

@Nullable
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}

@Override
public void onCreate() {
mBinder=new MyBinder();
if(mConn==null){
mConn=new MyConn();
}
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
//第一次绑定对方。
//再第二次还会绑定一次
LocalService.this.bindService(new Intent(this,RemoteService.class),mConn,BIND_IMPORTANT);
return super.onStartCommand(intent, flags, startId);
}

class  MyBinder extends IProcessService.Stub{

public String getServiceName(){
return  "LocalService";
}
}
class MyConn implements ServiceConnection{

@Override
public void onServiceConnected(ComponentName name, IBinder service) {
Log.i("TAG","本地链接远程服务成功");
Toast.makeText(LocalService.this,"链接远程服务成功",Toast.LENGTH_LONG).show();

}

@Override
public void onServiceDisconnected(ComponentName name) {
//对方（remoteService）被干掉了
Log.i("TAG","remoteService服务被杀");
Toast.makeText(LocalService.this,"remoteService服务被杀",Toast.LENGTH_LONG).show();
//第二次启动对方（对方会走onStart再绑定我）
LocalService.this.startService(new Intent(LocalService.this,RemoteService.class));
//第二次绑定对方（我可以再次绑定对方）
LocalService.this.bindService(new Intent(LocalService.this,RemoteService.class),mConn, Context.BIND_IMPORTANT);
}
}

}
