在我的项目中，我试图通过使用将我当前的位置发布到服务器LocationManager。为此，我通过使用OnLocationChanged位置管理器中的方法获得了纬度和经度值。同样在按钮单击事件中，我尝试使用地理编码器功能将经纬度值转换为地址。但它使我的应用程序崩溃。
按钮点击代码：

if(providergps.contains("gps"))

// isNetworkAvailable(h, 2000);

Boolean conn = check.checkNow(getApplicationContext());
Boolean conn1=AsyncClass.result;
if(conn==true && conn1==true){
Criteria criteria = new Criteria();
provider = locationManager.getBestProvider(criteria, false);
location = locationManager.getLastKnownLocation(provider);
locationManager.requestLocationUpdates(provider,0,0,Disclaimer.this);
Toast.makeText(getApplicationContext(), latlan, Toast.LENGTH_LONG).show();

笔记：
它专门用于某些类型的设备，例如 Galaxy S4、Galaxy Note 2
此外，当我检查经纬度值时，它会显示类似 (13.1270,803.2701) 的值
