问题描述
service中总是获取不到context,sendBroadcast报空指针异常
`public class HandleMessage extends Service{
private String qrcontent = null;private Context context = this;@Overridepublic void onCreate() { super.onCreate(); context = this;}
public void doSomething(final String content){
qrcontent = content; new Thread(new Runnable() {@Overridepublic void run() {//发送广播Intent intent=new Intent();intent.putExtra('qrcontent', qrcontent);intent.setAction('com.HandleMessage');if(intent != null){ LocalBroadcastManager.getInstance(context).sendBroadcast(intent);}else{ Log.e('---','null intent');} } }).start();}
}`
问题解答
回答1：服务在哪启动的
回答2：为什么开个线程去发广播？
