android - 进度对话框导致 "window leak"

Question

我有一个名为 requestLocation 的方法，它启动一个进度对话框。我从 onResume() 调用此方法；

我的方法:

public void requestLocation() {
    try { 
        progressDialog = ProgressDialog.show(this, "", "Obtaining Location Service", true);
    }
    catch(Exception e) {

    }

    updates=0;
    startingLocal = null;
    latestLocal = null;
    gps = null;
    gps = new KNLocationService(this);
    gps.setParent(this);
    // check if GPS enabled
    if (gps.canGetLocation()) {

        double latitude = gps.getLatitude();
        double longitude = gps.getLongitude();

        //progressDialog.dismiss();
        //locationServiceText.setText("Aquiring location");

    } else {
        try { 
            progressDialog.dismiss();
        } catch (Exception e) {

        }

        locationServiceText.setText("No LocationService Provided");
    }

}

但是我收到以下错误，我假设是由于进度对话框造成的，但我似乎无法找出到底是什么导致了它..

我似乎没有使应用程序崩溃，但我仍然想纠正这个问题。

您必须关闭对话框:

@Override
protected void onDestroy() {
    super.onDestroy();
    progressDialog.dismiss();
}
