android - 当我没有注册任何接收者时，Activity 泄露了 IntentReceiver

Question

在 list 中，我只有 Activity ，接收器上没有任何服务。当我完成 Activity 时，我在 logcat 中看到了这个:

E/ActivityThread: Activity com.example.some.activity has leaked IntentReceiver com.android.internal.policy.impl.PhoneWindow$1@41bbe958 that was originally registered here. Are you missing a call to unregisterReceiver()?

很遗憾我还没有注册任何接收器所以我不知道要注销什么

Answer 1

您需要在停止 Activity 时注销接收器:

@Override
protected void onStop()
{
    unregisterReceiver(yourReceiver);
    super.onStop();
}

希望这能解决您的问题。
