私は自分の場所を取得しようとしています.以下は、エラーが発生しているコードです. Log Cat を以下に示します。助けてください。また、緯度と経度が格納されている変数を知りたいです。

MyLocation.java

public class MyLocation extends Activity{ 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
  super.onCreate(savedInstanceState); 
  setContentView(R.layout.main); 

  /* Use the LocationManager class to obtain GPS locations */ 
  LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); 

  LocationListener mlocListener = new MyLocationListener(); 
  mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener); 
} 

/* Class My Location Listener */ 
public class MyLocationListener implements LocationListener 
{ 

  public void onLocationChanged(Location loc) 
  { 

    loc.getLatitude(); 
    loc.getLongitude(); 

    String Text = "My current location is: " + 
    "Latitud = " + loc.getLatitude() + 
    "Longitud = " + loc.getLongitude(); 

    Toast.makeText( getApplicationContext(), Text, Toast.LENGTH_SHORT).show(); 
  } 

  public void onProviderDisabled(String provider) 
  { 
    Toast.makeText( getApplicationContext(), "Gps Disabled", Toast.LENGTH_SHORT ).show(); 
  } 

  public void onProviderEnabled(String provider) 
  { 
    Toast.makeText( getApplicationContext(), "Gps Enabled", Toast.LENGTH_SHORT).show(); 
  } 

  public void onStatusChanged(String provider, int status, Bundle extras) 
  { 

  } 
} 
}

あなたのエラー（貼り付けたスタックトレースによると）は、場所の問題とは何の関係もありません。

クラス PostActivity が見つからないため、ClassNotFoundException が発生します。

実際に失敗するコードを貼り付けていないと思います
