Android BLE扫描失败\u仅在某些设备上已启动（错误代码1）

我正在写一个BLE扫描器，它可以经常扫描外设、连接和断开连接

我正在“循环”扫描-关闭2秒，然后再打开10秒-因为我在某个地方（将尝试查找参考）读到，否则（Android 7.0之后）操作系统将在30分钟左右后停止后台扫描。我也经历过类似的事情

问题是，在某些设备上（例如，摩托罗拉Moto Z和谷歌Pixel），我收到一个错误，表明该应用程序已经开始使用这些参数进行扫描

但是，在我的扫描算法中，我强制在尝试开始扫描之前调用

stopScan

。下面是一个相关的代码示例，它在提到的设备上产生错误。这只是代码的扫描部分

private final int SCANNER_DOWN_TIME = 2000;
private final int SCANNER_LIFETIME_MS = 10000;

private Runnable runnable = new Runnable() {
        private BluetoothLeScanner scanner;

        final ScanSettings.Builder builder = new ScanSettings.Builder();
        final ScanSettings settings = builder.setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY)
                .build();

        public void run() {
            try {
                bootScanner();
            } catch (Exception e) {
                Sentry.capture(e);
            }
        }

        class StartScannerAndScheduleReboot implements Runnable {
            @Override
            public void run() {
                if (bluetoothAdapter.isEnabled()) {
                    scanner = bluetoothAdapter.getBluetoothLeScanner();
                    if (scanner != null) {
                        scanner.startScan(null, settings, sensorReadingHandler);
                    }
                } else {
                    bluetoothAdapter.enable();
                }

                bootScanHandler = new Handler(Looper.getMainLooper());
                bootScan = new RebootScanner();
                bootScanHandler.postDelayed(bootScan, SCANNER_LIFETIME_MS);
            }
        }

        class RebootScanner implements Runnable {
            @Override
            public void run() {
                bootScanner();
            }
        }

        private void bootScanner() {
            try {
                scanner.stopScan(sensorReadingHandler);
            } catch (Exception e) {
                /* We can ignore this - there are cases that this will happen & it's ok */
            }

            startScanHandler = new Handler(Looper.getMainLooper());
            startScan = new StartScannerAndScheduleReboot();
            startScanHandler.postDelayed(startScan, SCANNER_DOWN_TIME);
        }

        private ScanCallback sensorReadingHandler = new ScanCallback() 

{ /* I don't believe the scanCallback code is relevant, as this happens before any connections are even attempted. */ }

        };

不足为奇的是，该应用程序仍然能够读取可传输的数据，但有些数据被删除了。这让我相信我不应该忽略这个错误。

你找到解决方案了吗？
