Android PhoneStateListener将不会发布,并且之前发布的答案均无效
这个问题以前被问过多次,但没有一个答案能为我解决这个问题。我已经尝试了我能找到的每一种方法,通过按下按钮、进入onPause和onDestroy来注销我的听众;但即使在应用程序关闭时,侦听器仍然存在。更重要的是,我正在祝酒我的侦听器正在填充的数组的大小,即使当应用程序关闭时,祝酒仍然会保持并继续增加。我尝试过使用null和LISTEN_NONE以及我在网上能找到的所有东西Android PhoneStateListener将不会发布,并且之前发布的答案均无效,android,telephonymanager,phone-state-listener,Android,Telephonymanager,Phone State Listener,这个问题以前被问过多次,但没有一个答案能为我解决这个问题。我已经尝试了我能找到的每一种方法,通过按下按钮、进入onPause和onDestroy来注销我的听众;但即使在应用程序关闭时,侦听器仍然存在。更重要的是,我正在祝酒我的侦听器正在填充的数组的大小,即使当应用程序关闭时,祝酒仍然会保持并继续增加。我尝试过使用null和LISTEN_NONE以及我在网上能找到的所有东西 // Name of this file is Second.class public class Second exten
