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
