相关疑难解决方法(0)

我正在使用Nexus 5开发一个使用蓝牙低功耗的应用程序.它在Lollipop上工作,现在它不能用于Marshmallow.我在清单和活动中的runTime上设置了ACCESS_COARSE_LOCATION和ACCESS_FINE_LOCATION权限.

这是ScanFilters列表:

mScanFilterTest = new ScanFilter.Builder().build();
mScanFilter = new ArrayList<ScanFilter>();
mScanFilter.add(mScanFilterTest);

这些是设置:

mScanSettings = new ScanSettings.Builder().setScanMode(ScanSettings.SCAN_MODE_LOW_POWER).setReportDelay(0)
                .setCallbackType(ScanSettings.CALLBACK_TYPE_ALL_MATCHES).build();

这些是我的回调:

 mBLEScan = new ScanCallback() {
     @Override
     public void onScanResult(int callbackType, ScanResult result) {
         super.onScanResult(callbackType, result);
         Log.i(TAG, "******************************************");
         Log.i(TAG, "The scan result " + result);
         Log.i(TAG, "------------------------------------------");
         }
     };

这是我的电话:

mBluetoothLeScanner.startScan(mScanFilter, mScanSettings, mBLEScan);

它开始扫描但没有找到任何设备.请帮我!!!!
