接收蓝牙广播onReceive中getStringExtra()出现错误

Posted 2020-07-23 goodpan

原因：getStringExtra()为空导致

解决：用以下判断接收

Bundle bundle = intent.getExtras();
                if (bundle != null) {
                    String data = bundle.getString(BluetoothLeService.EXTRA_DATA);
                   
                    if (data != null) {
                       
                    }
                }

 

Bundle bundle = intent.getExtras();
if (bundle != null) {
    String data = bundle.getString(BluetoothLeService.EXTRA_DATA);
    Log.e("mainData1",data);
    //显示到界面
if (data != null) {
        Log.e("mainData2",data);
        //初始化圆形进度条
initArcProgressBar(100,Integer.parseInt(data),"优");
    }
}
