Geocoder 屏蔽了我的 android 应用

Question

这是我的代码：

private void getGeocoderForCheckout(int section) {
    Log.i("","current address getGeocoderForCheckout");
    setViewOver();
    loader.setVisibility(View.VISIBLE);
    sect = section;
    selectedSD = currentPlace;
    PSLocationCenter.getInstance().pref.setCheckoutType(context, "Current address");
    Geocoder geocoder = new Geocoder(context, Locale.getDefault());
    Log.i("","current address getGeocoderForCheckout");
    try {
        Log.i("","current address getGeocoderForCheckout1" + currentPlace);
        double lng = currentPlace.getLon();
        Log.i("","current address getGeocoderForCheckout1 lat lng: " + currentPlace.getLat() + "..." + lng);
        List<Address> address = geocoder.getFromLocation(currentPlace.getLat(), lng, 1);
        Log.i("","current address getGeocoderForCheckout1");
        if (address.size() > 0) {
            String title = address.get(0).getMaxAddressLineIndex() > 0 ? address.get(0).getAddressLine(0) : "";
            new PlacesAPI(context, currentAddressListener).execute(PlacesAPI.TYPE_AUTOCOMPLETE, "&input=" + URLEncoder.encode(title, "utf8"));
        }
    } catch (Exception e) {
        Log.i("","current address errorr: "+ e.getMessage());
        removeViewOver();
        Toast.makeText(context, context.getString(R.string.geocoder_error), Toast.LENGTH_SHORT).show();
        loader.setVisibility(View.GONE);
        Utils.appendLog("onmap long click errror : " + e.getMessage());
        e.printStackTrace();
    }
}

我的问题是它总是在这一行阻止应用程序：

List<Address> address = geocoder.getFromLocation(currentPlace.getLat(), lng, 1);

这是我得到的日志：

 09-11 12:22:59.725 25648-25648/nl.hgrams.passenger I/: current address getGeocoderForCheckout

我尝试调试该应用程序，但在进入 geocoder.getFromLocation 行后，它在 Looper 处停了下来。从那一刻起，应用程序就没有响应了。

编辑：如果我按下 "getFromLocation" 功能将我带到它。它带我进入 Geocoder.java 这个功能：

 public List<Address> getFromLocation(double latitude, double longitude, int maxResults)
    throws IOException {
    if (latitude < -90.0 || latitude > 90.0) {
        throw new IllegalArgumentException("latitude == " + latitude);
    }
    if (longitude < -180.0 || longitude > 180.0) {
        throw new IllegalArgumentException("longitude == " + longitude);
    }
    try {
        List<Address> results = new ArrayList<Address>();
        String ex =  mService.getFromLocation(latitude, longitude, maxResults,
            mParams, results);
        if (ex != null) {
            throw new IOException(ex);
        } else {
            return results;
        }
    } catch (RemoteException e) {
        Log.e(TAG, "getFromLocation: got RemoteException", e);
        return null;
    }
}

其中：

 mService.getFromLocation(latitude, longitude, maxResults,
            mParams, results);

为红色并表示："cannot resolve method".....

PS：我在其他地方也用过这个功能，还可以。所以我不知道这里可能出了什么问题。

尝试在后台线程中调用 getFromLocation()。来自 documentation :

It may be useful to call this method from a thread separate from your primary UI thread.
