    try{
      ScreenRecord.startRecord(
        {isAudio: true},
        "file:///storage/emulated/0/Android/data/io.ionic.starter/files/test.mp4",
        (success)=> {
          this.recording=true;
          alert(success);
        }, (error)=>{
          alert(error);
        }
      );
    }catch{e=>{

    }}
  }
stop(){
    try{
      ScreenRecord.stopRecord(
        (success)=>{
          this.recording=false;
          alert(success + " : " + "file:///storage/emulated/0/Android/data/io.ionic.starter/files/test.mp4");
        },
        (error)=>{
          alert(error);
        }
      );
    }catch{e=>{

    }}
  }
