Has leaked intentreceiver ... that is originally registerd here. Is you missing a call to unregister

Today I encountered this error: has leaked intentreceiver ... that is originally registerd here. Is you missing a call to Unregisterreceiver

：

The Chinese meaning of this error is that it has overflowed the intentreceiver, did you forget to call the method of canceling the broadcast?

Reason for the problem:

The reason is overflow intentreceiver, because there is receiver has not been unregister after the register, repeated several times after causing intentreceiver leakage

But I actually have to call Unregisterreceiver (Batteryreceiver), then why this problem still occurs

Workaround:

In order to avoid this problem, register the broadcast and write off the broadcast to appear in pairs , but at the same time in order to avoid the problem of NULL pointers, we'd better add a flag-bit flag

/** * Flag bit, whether Broadcasereceiver open, default to False */boolean Flag=false;

Change flag to True when registering a broadcast

/** * Register broadcast */private void Registerreceiver () {flag=true;intentfilter filter = new Intentfilter (); Filter.addaction (Intent . action_battery_changed); batteryreceiver=new batteryreceiver (); Registerreceiver (batteryreceiver, filter);}

Before cancelling the broadcast, first determine if flag is true (that is, whether the broadcast has been registered), or if true, to unregister the broadcast

@Overridepublic void OnPause () {if (flag) {flag=false;unregisterreceiver (batteryreceiver);} Super.onpause ();}

The reason to add flag is to avoid not registering the broadcast, but to cancel the broadcast, so there will be a null pointer
