什么似乎是在我运行我的应用程序的每个SGS3设备上粉碎的原因？ 这是唯一无法运行的设备（4.1.2 OS版本）。 我试过：LG optimus one + black，N4，HTC HD2，SGS 1 + 2 ..等等...

在Manifest文件中，我做了：

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="10" />

那些是最相关的行注册。 Manifest.xml（针对我的问题）。

onCreate方法：

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Getting reference to MapView
        mapView = (MapView) findViewById(R.id.map_view);
        tvLocation = (TextView)findViewById(R.id.tv_location);
        mapView.setKeepScreenOn(true);

        // Setting Zoom Controls on MapView
        mapView.setBuiltInZoomControls(true);
        mapView.setTraffic(true);
        mapView.setSatellite(false);

        ImageButton settings = (ImageButton)findViewById(R.id.settingsButton);
        settings.setOnClickListener(this);

        Button helpme = (Button)findViewById(R.id.helpMeButton);    //find Button and gives a name: 'help'
        ToggleButton mapExchangeToggleButton = (ToggleButton)findViewById(R.id.mapExchangeToggleButton);    
        helpme.setOnClickListener(this);    //register Button as an OnClicklistener
        mapExchangeToggleButton.setOnClickListener(this);

        // Getting LocationManager object from System Service LOCATION_SERVICE
        LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

        // Creating a criteria object to retrieve provider
        Criteria criteria = new Criteria();

        // Getting the name of the best provider
        String provider = locationManager.getBestProvider(criteria, true);

        // Getting Current Location
        Location location = locationManager.getLastKnownLocation(provider);

        if(location!=null){
            onLocationChanged(location);
        }

onResume方法：

public void onResume(){
        super.onResume();

        SharedPreferences pre = getSharedPreferences(PREFS_NAME,MODE_PRIVATE);
        phoneNumber = pre.getString("phone","" );
    }

LogCat是：

onLocationChanged（）：

public void onLocationChanged(Location location) {

        double latitude = location.getLatitude();

        double longitude = location.getLongitude();


         );

        Geocoder geocoder;
        List<Address> addresses = null;

        geocoder = new Geocoder(this, Locale.getDefault());
        try {
            addresses = geocoder.getFromLocation(latitude, longitude, 1);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        address = addresses.get(0).getAddressLine(0);
        city = addresses.get(0).getAddressLine(1);
        country = addresses.get(0).getAddressLine(2);

        tvLocation.setText("Street Address: " +  address+ "\nCity: "+city +"\nCountry: " +country);

        GeoPoint point = new GeoPoint((int)(latitude * 1E6), (int)(longitude*1E6));

        MapController mapController = mapView.getController();

        mapController.animateTo(point);

        mapController.setZoom(15);

        mapView.invalidate();

        List<Overlay> mapOverlays = mapView.getOverlays();

        Drawable drawable = this.getResources().getDrawable(R.drawable.cur_position);

        CurrentLocationOverlay currentLocationOverlay = new CurrentLocationOverlay(drawable);

        OverlayItem currentLocation = new OverlayItem(point, "Current Location", "Latitude : " + latitude + ", Longitude:" + longitude);

        currentLocationOverlay.addOverlay(currentLocation);

        mapOverlays.clear();

        mapOverlays.add(currentLocationOverlay);        

    }

答案 0 :(得分：0)

你正在捕捉并打印：

java.io.IOException: Service not Available

表示地址永远不会被设置为null：

List<Address> addresses = null;

因此当您尝试访问该列表中的项目时，您可能会收到NullPointerException：

address = addresses.get(0).getAddressLine(0);

看起来android.location.Geocoder在该特定设备上不可用。我会检查权限等内容，并启用/启用GPS。
