注意：-platform.ready((是诀窍，将代码放入platform.ready((函数中

constructor(private platform: Platform,private backgroundMode: BackgroundMode){
platform.ready().then(() => {
console.log("background mode off")
this.backgroundMode.enable();
console.log("background mode check",this.backgroundMode.isActive(), this.backgroundMode.isEnabled(),this.backgroundMode.isScreenOff);

// this.backgroundMode.enable();

console.log("-------------------->", this.backgroundMode.isEnabled());
console.log("-------------------->", this.backgroundMode.isActive());

this.backgroundMode.on("activate").subscribe(()=>{

console.log("background mode on");

});
});
}
