has leaked IntentReceiver ...that was originally registerd here.Are you missing a call to unregister

今天碰到了这个错误：has leaked IntentReceiver ...that was originally registerd here.Are you missing a call to unregisterReceiver

如图所示：

这个错误的中文意思是，已经溢出了IntentReceiver，你是忘记了调用注销广播的方法吗？

原因所在：

之所以是溢出IntentReceiver，原因是有receiver 被register后没有被unregister,反复几次后造成 intentReceiver 泄漏

但我其实是有调用unregisterReceiver(batteryReceiver)，那为什么还会出现这个问题

解决方法：

为了避免这个问题的出现，注册广播和注销广播要成对出现，但同时又为了避免空指针的问题，我们最好加一个标志位flag

/*** 标志位，是否broadcaseReceiver开启，默认为false*/boolean flag=false;

在注册广播的时候，将flag变为true

/*** 注册广播*/private void registerReceiver() {flag=true;IntentFilter filter = new IntentFilter();filter.addAction(Intent.ACTION_BATTERY_CHANGED);batteryReceiver=new BatteryReceiver();registerReceiver(batteryReceiver, filter);}

在注销广播的之前，先判断flag是否为真，（即是否广播已经被注册了），如果为真，则注销广播

@Overridepublic void onPause() {if(flag){flag=false;unregisterReceiver(batteryReceiver);}super.onPause();}

之所以加flag，就是避免没有注册广播，但却注销广播，这样会有空指针
