            <receiver android:name=".receiver.BootBroadcastReceiver">

    启动 app核心服务

    package com.boai.base.receiver;
    
    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    
    import com.boai.base.service.CoreService;
    
    
    public class BootBroadcastReceiver extends BroadcastReceiver {
    
        @Override
        public void onReceive(Context context, Intent intent) {
    
            // 启动App核心Service
            Intent startCoreServiceIntent = new Intent(context, CoreService.class);
            context.startService(startCoreServiceIntent);
        }
    
    }
    

      服务类

    public class CoreService extends Service
    

      在服务类中 注册广播

       @Override
        public void onCreate() {
            super.onCreate();
    
            // 注册广播
            regBroadcastReceiver();
        }
    

      生成需要的广播

    private void regBroadcastReceiver() {
            IntentFilter mPushMsgBrFileter = new IntentFilter();
            mPushMsgBrFileter.addAction(Constants.BR_ACTION_UMENG_PUSH_MSG);
            mPushMsgBrFileter.addAction(Constants.BR_ACTION_USER_LOGIN);
            mPushMsgBrFileter.addAction(Constants.BR_ACTION_USER_LOGOUT);
            registerReceiver(mBroadcastReceiver, mPushMsgBrFileter);
        }
    

      广播接收处理

       //创建一个可根据需要创建新线程的线程池

    mThreadPool = Executors.newCachedThreadPool();
        // 广播接收
        private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                String action = intent.getAction();

                    if (null == tempObj) {
