最近开发的时候，测试小伙伴经常来找我，“为什么咱家程序放到后台，聊了会qq就得重启了呢？”我脑门一亮，“稍等，一会给你”。然后我就进入了程序流氓（进程保活）之旅。
对于进程保活，其实吧，现在对于MIUI、EMUI等等许多高度定制的系统并没有100%的保活方案，该死还是死掉，但是做了一定的操作，还是可以适当的提高存活的。如下就是我用到的保活方案。

1、启动软件的时候激活本地服务和远程服务

        startService (new Intent (this, MainService.class));
        startService (new Intent (this, RemoteService.class));

2、本地服务代码

/**
 * content:后台运行的服务
 * Actor:韩小呆
 * Time:2018/5/3
 */
public class MainService extends Service {
    MyBinder binder;
    MyConn conn;

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

    @Override
    public void onCreate() {
        super.onCreate();
        binder = new MyBinder();
        conn = new MyConn();
    }

    class MyBinder extends IMyAidlInterface.Stub {

        @Override
        public String getServiceName() throws RemoteException {
            return MainService.class.getSimpleName();
        }
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        this.bindService(new Intent(MainService.this, RemoteService.class), conn, Context.BIND_IMPORTANT);
        return START_STICKY;
    }

    class MyConn implements ServiceConnection {

        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {

        }

        @Override
        public void onServiceDisconnected(ComponentName name) {

            Intent intent = new Intent(MainService.this, RemoteService.class);
            if (Build.VERSION.SDK_INT >= 26) {
                  \\适配8.0机制
                MainService.this.startForegroundService(intent);
            } else {
                MainService.this.startService(intent);
            }
            //绑定远程服务
            MainService.this.bindService(new Intent(MainService.this, RemoteService.class), conn, Context.BIND_IMPORTANT);

        }
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Intent intent = new Intent(MainService.this, RemoteService.class);
        \\适配8.0机制
        if (Build.VERSION.SDK_INT >= 26) {
            MainService.this.startForegroundService(intent);
         
        } else {
            MainService.this.startService(intent);
        }
        MainService.this.bindService(new Intent(MainService.this, RemoteService.class), conn, Context.BIND_IMPORTANT);
    }
}

3、远程服务代码

/**
 * content:后台运行的服务
 * Actor:韩小呆
 * Time:2018/5/3
 */
public class RemoteService extends Service {
    MyConn conn;
    MyBinder binder;

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

    @Override
    public void onCreate() {
        super.onCreate();
        conn = new MyConn();
        binder = new MyBinder();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {


        this.bindService(new Intent(this, MainService.class), conn, Context.BIND_IMPORTANT);

        return START_STICKY;
    }

    class MyBinder extends IMyAidlInterface.Stub {
        @Override
        public String getServiceName() throws RemoteException {
            return RemoteService.class.getSimpleName();
        }
    }

    class MyConn implements ServiceConnection {

        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {

        }

        @Override
        public void onServiceDisconnected(ComponentName name) {

            Intent intent = new Intent(RemoteService.this, MainService.class);
            //开启本地服务
            if (Build.VERSION.SDK_INT >= 26) {
               \\适配8.0机制
                RemoteService.this.startForegroundService(intent);
            } else {
                RemoteService.this.startService(intent);
            }
            //绑定本地服务
            RemoteService.this.bindService(new Intent(RemoteService.this, MainService.class), conn, Context.BIND_IMPORTANT);
        }

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Intent intent = new Intent(RemoteService.this, MainService.class);
        //开启本地服务
        if (Build.VERSION.SDK_INT >= 26) {
           \\适配8.0机制
            RemoteService.this.startForegroundService(intent);
        } else {
            RemoteService.this.startService(intent);
        }
        //绑定本地服务
        RemoteService.this.bindService(new Intent(RemoteService.this, MainService.class), conn, Context.BIND_IMPORTANT);

    }
}

4、创建AIDL实现远近程服务通信

// Declare any non-default types here with import statements

interface IMyAidlInterface {
    String getServiceName();
}

AIDL文件
