java - 无法停止前台服务 stopSelf() 和 stopForeground(true) 不起作用

Question

我正在尝试停止我的前台服务，但我的代码似乎无法正常工作

Intent intent = new Intent(SplashScreenActivity.this, DNSService.class);
stopService(intent);

这是我的服务来源:

public class DNSService extends VpnService {
public final static String DNS_MODEL = "DNSModelIntent";

private VpnService.Builder builder = new VpnService.Builder();
private ParcelFileDescriptor fileDescriptor;
private Thread mThread;
private boolean shouldRun = true;
private DatagramChannel tunnel;
private DNSModel dnsModel;

public static final String ACTION_CONNECT       = DNSService.class.getName() + ".START";
public static final String ACTION_DISCONNECT    = DNSService.class.getName() + ".STOP";

@Override
public void onDestroy() {
    stopSelf();
    stopForeground(true);
    super.onDestroy();
}

@Override
public void onCreate() {
    super.onCreate();
}

private void setTunnel(DatagramChannel tunnel) {
    this.tunnel = tunnel;
}

private void setFileDescriptor(ParcelFileDescriptor fileDescriptor) {
    this.fileDescriptor = fileDescriptor;
}

@Override
public int onStartCommand(final Intent intent, int p1, int p2) {
    mThread = new Thread(() -> {
        try {
            dnsModel = intent.getParcelableExtra(DNS_MODEL);

            setFileDescriptor(builder.setSession(DNSService.this.getText(R.string.app_name).toString()).
                    addAddress("192.168.0.1", 24).addDnsServer(dnsModel.getFirstDns()).addDnsServer(dnsModel.getSecondDns()).establish());
            setTunnel(DatagramChannel.open());
            tunnel.connect(new InetSocketAddress("127.0.0.1", 8087));
            protect(tunnel.socket());
            while (shouldRun)
                Thread.sleep(100L);
        } catch (Exception exception) {
            exception.printStackTrace();
        } finally {
            if (fileDescriptor != null) {
                try {
                    fileDescriptor.close();
                    setFileDescriptor(null);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    });

    mThread.start();

    return Service.START_STICKY;
}
}

您必须关闭 onDestroy() 内所有正在运行的进程才能停止工作。原因是启动的线程正在其他进程上运行。因此，在您终止后，您的服务线程仍在运行。
