说明:
ibeacon设备会主动发射蓝牙信号,当手机打开蓝牙靠近ibeacon设备时,就会收到设备发送的蓝牙信号,这时只需要根据ibeacon设备的uuid、major、minor、mac这四个值,就可以确认是哪一台ibeacon设备,然后调用服务端考勤接口(ibeacon设备只为了确认手机在考勤机边上,不需要发送考勤数据到ibeacon设备上),即可实现蓝牙考勤。
一、添加静态权限(在AndroidManifest.xml文件中添加,需要蓝牙和定位权限)
二、检测与开启蓝牙、GPS
1.是否支持蓝牙:
if (!context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)) { ToastUtils.show("本机不支持蓝牙功能, 无法蓝牙打卡"); ((Activity) context).finish(); return false; } final BluetoothManager bm = (BluetoothManager) context.getSystemService(Context.BLUETOOTH_SERVICE); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) { mBleAdapter = bm.getAdapter(); //mBleAdapter为全局变量,为BluetoothAdapter对象 } if (bleAdapter == null) { ToastUtils.show("本机不支持低功耗蓝牙功能, 无法蓝牙打卡"); ((Activity) context).finish(); return false; } return true;
2.是否开启GPS:
LocationManager lm = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE); boolean gps = lm.isProviderEnabled(LocationManager.GPS_PROVIDER); boolean network = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER); if (gps || network) { return true; } return false;
3.开启GPS:
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); context.startActivityForResult(intent, ActivityCode.ACTIVITY_CODE_GPS);
4.开启蓝牙:
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE); ((Activity) mContext).startActivityForResult(enableBtIntent, ActivityCode.ACTIVITY_CODE_OPEN_BLE);
三、动态申请蓝牙权限
private boolean check(Context context, String permission) { return ContextCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED; } /** * 权限申请 */ private void searchBle(){ if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (!check(mContext, Manifest.permission.ACCESS_FINE_LOCATION) || !check(mContext, Manifest.permission.ACCESS_COARSE_LOCATION)) { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, ACCESS_LOCATION); } else { //执行蓝牙搜索 } } else { //执行蓝牙搜索 } } @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { switch (requestCode) { case ACCESS_LOCATION: if (hasAllPermissionsGranted(grantResults)) { //执行蓝牙搜索 } else { ToastUtils.show("请开启权限"); } break; } }
四.搜索蓝牙
/** * 搜索蓝牙 */ public void searchBle() { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) { mBleAdapter.startLeScan(mLeScanCallback); } } /** * 搜索结果回调 */ private BluetoothAdapter.LeScanCallback mLeScanCallback = new BluetoothAdapter.LeScanCallback() { @Override public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) { //fromScanData方法将ibeacon数据转换为实体对象,内部包括了uuid、major、minor、mac、distance等信息 final BleUtil.DeviceInfo info = BleUtil.fromScanData(device, rssi, scanRecord); if (info == null || TextUtils.isEmpty(info.uuid) || info.major <= 0 || info.minor <= 0 || TextUtils.isEmpty(info.mac)) { return; } if (mUuids == null || mUuids.isEmpty()) { //此处关闭蓝牙搜索 mBleAdapter.stopLeScan(mLeScanCallback); return; } for (MachineInfo machineInfo : mUuids) { if (info.uuid.equalsIgnoreCase(machineInfo.uuid) && (!TextUtils.isEmpty(machineInfo.major) && info.major == Integer.parseInt(machineInfo.major)) && (!TextUtils.isEmpty(machineInfo.minor) && info.minor == Integer.parseInt(machineInfo.minor)) && info.mac.equalsIgnoreCase(machineInfo.mac) && info.distance <= MAX_DISTANCE) { mCOnnected= true; //回调通知外部,界面更新可考勤状态 if (mListener != null) { mListener.onConnected(); } //此处是延时调用stopLeScan关闭蓝牙搜索 beginTimer(); break; } } } };
五、考勤
此步调用服务端提供的API增加考勤记录
