Question

Android新手，目前正在使用锁屏应用程序。在我的应用程序中，当我在我的Xperia手机中运行时，异常发生..我在函数newKeyguardLock（）中发现了删除线。我认为这是问题..任何人都可以帮我解决这个问题。我的代码： -

KeyguardManager keyguardManager = (KeyguardManager) getSystemService(Activity.KEYGUARD_SERVICE);
    KeyguardManager.KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);
    lock.disableKeyguard();

我的日志是： -
