要解决“BluetoothLeScanner的startScan()在没有日志的情况下无法工作”的问题,可以按以下步骤操作:
BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
BluetoothAdapter bluetoothAdapter = bluetoothManager.getAdapter();
BluetoothLeScanner bluetoothLeScanner = bluetoothAdapter.getBluetoothLeScanner();
if (!bluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
private BluetoothAdapter.LeScanCallback leScanCallback = new BluetoothAdapter.LeScanCallback() {
@Override
public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) {
// 处理扫描结果
}
};
bluetoothLeScanner.startScan(leScanCallback);
这些步骤将确保BluetoothLeScanner的startScan()在没有日志的情况下工作。请根据您的实际需求进行适当的调整和修改。
