Question

i使用ionic4

i导入离子科尔多瓦插件添加科尔多瓦插件背景模式 npm安装@ ionic-native / background-mode

在我的项目中

我使用代码

Command: Launch Microsoft Word
The file /Applications/ microsoft word.app does not exist.

我的手机关闭时屏幕不起作用入侵并解锁

或通过

进行测试

   ....
   import { BackgroundMode } from '@ionic-native/background-mode/ngx';
   ....
   private backgroundMode: BackgroundMode,
   ....
   this.backgroundMode.enable();
   this.backgroundMode.isScreenOff( () => {
    alert('screen off');
    this.backgroundMode.unlock();
   });

或

   ....
   import { BackgroundMode } from '@ionic-native/background-mode/ngx';
   ....
   private backgroundMode: BackgroundMode,
   ....
   this.backgroundMode.enable();
   this.backgroundMode.isScreenOff( () => {
    alert('screen off');
    this.backgroundMode.wakeUp();
    this.backgroundMode.unlock();
   });

或

....
   import { BackgroundMode } from '@ionic-native/background-mode/ngx';
   ....
   private backgroundMode: BackgroundMode,
   ....
   this.backgroundMode.enable();
   this.backgroundMode.isScreenOff( function(bool) {
    if (bool) {
     alert('screen off');
     this.backgroundMode.wakeUp();
     this.backgroundMode.unlock();
    }else{
     alert('screen on');
    }
   });

或

....
   import { BackgroundMode } from '@ionic-native/background-mode/ngx';
   ....
   private backgroundMode: BackgroundMode,
   ....
   this.backgroundMode.enable();
   this.backgroundMode.isScreenOff( function(bool) {
     this.backgroundMode.wakeUp();
     this.backgroundMode.unlock();
   });

和BackgroundMode在app.moudel.ts中添加提供程序

但不能完全正常工作但有效的代码

   ....
   import { BackgroundMode } from '@ionic-native/background-mode/ngx';
   ....
   private backgroundMode: BackgroundMode,
   ....
   this.backgroundMode.enable();
   this.backgroundMode.wakeUp();
   this.backgroundMode.unlock();

如何解决使用this.backgroundMode.wakeUp（）;的问题和this.backgroundMode.unlock（）;何时关闭我的设备或手机的屏幕？

谢谢
