Question

在我的应用程序中，我有一个Service，其中包含一个Thread，可以启动和停止BLE广告：

public class BeaconSearchService extends Service {

     private void startAdvertisingThread() {
         (advertisingThread = new Thread("Advertising Thread") {
             @Override
             public void run() {
                //Ensure that advertising is off
                try {
                   BeaconSearchService.this.bluetoothLeAdvertiser.stopAdvertising(BeaconSearchService.this.advertiseCallback);
                } catch (Exception e) {
                }
                while(!isInterrputed()) {
                   AdvertiseSettings advertiseSettings = new AdvertiseSettings.Builder()
                      .setAdvertiseMode(AdvertiseSettings.ADVERTISE_MODE_LOW_LATENCY)
                      .setTxPowerLevel(AdvertiseSettings.ADVERTISE_TX_POWER_MEDIUM)
                      .setConnectable(true)
                      .build();
                   BeaconSearchService.this.advertiseData.getServiceUuids().clear();
                   BeaconSearchService.this.advertiseData.getServiceUuids().add(BeaconSearchService.this.getUuid());
                   long uptime = 5000;
                   long downTime = 7000;
                   //START ADVERTISING
                   try {
                       BeaconSearchService.this.bluetoothLeAdvertiser.startAdvertising(advertiseSettings, BeaconSearchService.this.advertiseData, BeaconSearchService.this.advertiseCallback);
                    } catch (Exception e) {
                        Log.e(LOG_TAG, e.getMessage(), e);
                    }
                    //SLEEP FOR 5 SEC
                    try {
                        sleep(upTime);
                    } catch (InterruptedException e) {
                        interrupt();
                        break;
                    }
                    //AFTER WAKE FROM SLEEP, STOP ADVERTISING
                    try {
                       BeaconSearchService.this.bluetoothLeAdvertiser.stopAdvertising(BeaconSearchService.this.advertiseCallback);
                    } catch (Exception e) {
                        Log.e(LOG_TAG, e.getMessage(), e);
                    }
                    //SLEEP FOR 7 SEC
                    try {
                        sleep(downTime);
                    } catch (InterruptedException e) {
                        interrupt();
                        break;
                    }
                    //RESTART THE CIRCLE IF NOT INTERRUPTED
             }
             //Ensure stop advertising while exiting
             try {
               BeaconSearchService.this.bluetoothLeAdvertiser.stopAdvertising(BeaconSearchService.this.advertiseCallback);
            } catch (Exception e) {
            }
         }).start();
     }

     @Override
     public void onDestroy() {
         try {
            advertisingThread.interrupt();
         } catch(Exception e) {
         }
     }
}

问题是当广告开启且Service和Thread关闭而没有调用onDestroy()方法（例如应用崩溃，应用程序进程被本地Android ROM自定义行为杀死或者在使用Android Studio进行开发时，从Playstore等新版本下载后重新启动应用程序，Android系统会保持BLE广告开启。因此，当我重新打开应用程序并嗅探BLE数据包时，我会看到我的应用程序的两个或更多广告“会话”。当我重新启动手机并且“孤儿”广告会话消失时，问题就解决了。

有没有办法在不强迫用户重启手机的情况下杀死所有“僵尸”广告会话？
