要解决Android 10上蓝牙低功耗扫描问题,可以尝试以下方法和代码示例:
// 检查位置权限
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
// 申请位置权限
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_LOCATION_PERMISSION);
} else {
// 已有位置权限,开始蓝牙扫描
startBluetoothScan();
}
private BluetoothAdapter.LeScanCallback mLeScanCallback = new BluetoothAdapter.LeScanCallback() {
@Override
public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) {
// 处理扫描结果
}
};
// 注册广播接收器
IntentFilter filter = new IntentFilter(BluetoothAdapter.ACTION_STATE_CHANGED);
registerReceiver(mBluetoothReceiver, filter);
BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
bluetoothAdapter.startLeScan(mLeScanCallback);
BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
bluetoothAdapter.stopLeScan(mLeScanCallback);
这些方法和代码示例可以帮助解决Android 10上蓝牙低功耗扫描问题。请根据您的具体情况进行适当的修改和调整。
