Can't get internet data at android 4.0.4

Question

I have a problem with my developed app for Android.
I trying to get data from Google Translate API via JSON Parser.
The application works perfectly on Emulator (v 2.1) and T-Mobile Move Balance (v 2.3.5) The problem happens at Android 4.0.4 (device ZTE BLADE III). When I trying to get data, it returns null pointer( NullPointerException which is surrounded by try-catch block).

There is app permisions at the Manifest

 <uses-sdk
    android:minSdkVersion="7"
    android:targetSdkVersion="17" />

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

I think is error in Manifest or settings configuration on the device (already checked internet connection and works with other apps. Browser works also), because the app works fine in older versions.
Any help would be appreciated. Thanks in advance.

I thought it isn't needed
Here is the Activity with one button and two spinners, with listener at the button

  public class OptionsActivity extends Activity {

private String mSourceLanguage, mDestinationLanguage;
private Spinner sourceSpinner, destinationSpinner;
private  static ArrayList<Language> languages;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_options);

    sourceSpinner = (Spinner)findViewById(R.id.spinner1);
    destinationSpinner = (Spinner)findViewById(R.id.spinner2);
    updateSpinners();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_options, menu);
    return true;
}

// isprakjanje na informacii na jazicite do ManuaInputActivity
public void submitLanguages(View v){
    mSourceLanguage = sourceSpinner.getSelectedItem().toString();
    mDestinationLanguage = destinationSpinner.getSelectedItem().toString();

    String sourceCode = "", destCode = "";
    sourceCode = getCode(mSourceLanguage);
    destCode = getCode(mDestinationLanguage);

    Intent intent = new Intent(this, ManualInputActivity.class);

    Bundle spinnerBundle = new Bundle();
    spinnerBundle.putString("sourceLanguage", mSourceLanguage + " ["+ sourceCode + "]");
    spinnerBundle.putString("sourceCode", sourceCode);
    spinnerBundle.putString("destinationLanguage", mDestinationLanguage + " [" + destCode + "]");
    spinnerBundle.putString("destinationCode", getCode(mDestinationLanguage));

    intent.putExtras(spinnerBundle);

    setResult(RESULT_OK, intent);
    super.finish();
}

// moze da mi treba pokasno za polnenje na spinner-ite
private ArrayAdapter<String> initializeSpinner(ArrayList<Language> lang){

    ArrayAdapter<String> spinnerAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,entries);

    return spinnerAdapter;
}

the LogCat looks like that when updateSpinners() method is modified like this:

private void updateSpinners(){
    GoogleRequest gr = new GoogleRequest();
    String result = gr.requestLanguages("en");
    languages = gr.getLanguagesFromJSONObject(result);
    sourceSpinner.setAdapter(initializeSpinner(languages));
    destinationSpinner.setAdapter(initializeSpinner(languages));
    try {

    } catch (NullPointerException e) {
        // TODO: handle exception
        Toast.makeText(this, "THIS IS IRRELEVANT NOW ...", Toast.LENGTH_SHORT).show();
    }   
}

Answer 1

use AsyncTask here's a link http://steveliles.github.com/android_s_asynctask.html may be this can help you solve your problem

Answer 2

Maybe your problem is because you are not using a AsyncTask to get that data.
