Question

Używam aplikacji Google google api i chcę pobrać najbliższą restaurację i kawiarnię, ale kiedy pobieram te dane za pomocą paska postępu jeden błąd występuje

class LoadPlaces extends AsyncTask<String, String, String> { 

    /** 
    * Before starting background thread Show Progress Dialog 
    * */ 
    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     pDialog = new ProgressDialog(MainActivity.this); 
     pDialog.setMessage(Html.fromHtml("<b>Search</b><br/>Loading Places...")); 
     pDialog.setIndeterminate(false); 
     pDialog.setCancelable(false); 
     pDialog.show(); 
    } 

    /** 
    * getting Places JSON 
    * */ 
    protected String doInBackground(String... args) { 
     // creating Places class object 
     googlePlaces = new GooglePlaces(); 

     try { 
      // Separeate your place types by PIPE symbol "|" 
      // If you want all types places make it as null 
      // Check list of types supported by google 
      // 
      String types = "cafe|restaurant"; // Listing places only cafes, restaurants 

      // Radius in meters - increase this value if you don't find any places 
      double radius = 1000; // 1000 meters 

      // get nearest places 
      nearPlaces = googlePlaces.search(gps.getLatitude(), 
        gps.getLongitude(), radius, types); 


     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

protected void onPostExecute(String file_url) { 
     // dismiss the dialog after getting all products 
     if(pDialog != null) 
      pDialog.dismiss(); 
     // updating UI from Background Thread 
     runOnUiThread(new Runnable() { 
      public void run() { 
       /** 
       * Updating parsed Places into LISTVIEW 
       * */ 
       // Get json response status 
       String status = nearPlaces.status; 

       // Check for all possible status 
       if(status.equals("OK")){

         for (Place p : nearPlaces.results) { 
          HashMap<String, String> map = new HashMap<String, String>(); 

          // Place reference won't display in listview - it will be hidden 
          // Place reference is used to get "place full details" 
          map.put(KEY_REFERENCE, p.reference); 

          // Place name 
          map.put(KEY_NAME, p.name); 


          // adding HashMap to ArrayList 
          placesListItems.add(map); 
         } 
         // list adapter 
         ListAdapter adapter = new SimpleAdapter(MainActivity.this, placesListItems, 
           R.layout.list_item, 
           new String[] { KEY_REFERENCE, KEY_NAME}, new int[] { 
             R.id.reference, R.id.name }); 

         // Adding data into listview 
         lv.setAdapter(adapter); 
        } 
       } 
       else if(status.equals("ZERO_RESULTS")){ 
        // Zero results found 
        alert.showAlertDialog(MainActivity.this, "Near Places", 
          "Sorry no places found. Try to change the types of places", 
          false); 
       } 
       else if(status.equals("UNKNOWN_ERROR")) 
       { 
        alert.showAlertDialog(MainActivity.this, "Places Error", 
          "Sorry unknown error occured.", 
          false); 
       } 
       else if(status.equals("OVER_QUERY_LIMIT")) 
       { 
        alert.showAlertDialog(MainActivity.this, "Places Error", 
          "Sorry query limit to google places is reached", 
          false); 
       } 
       else if(status.equals("REQUEST_DENIED")) 
       { 
        alert.showAlertDialog(MainActivity.this, "Places Error", 
          "Sorry error occured. Request is denied", 
          false); 
       } 
       else if(status.equals("INVALID_REQUEST")) 
       { 
        alert.showAlertDialog(MainActivity.this, "Places Error", 
          "Sorry error occured. Invalid Request", 
          false); 
       } 
       else 
       { 
        alert.showAlertDialog(MainActivity.this, "Places Error", 
          "Sorry error occured.", 
          false); 
       } 
      } 
     }); 

    } 

oraz metodę wyszukiwania dla klasy GooglePlaces jest

public PlacesList search(double latitude, double longitude, double radius, String types) 
     throws Exception { 

    this._latitude = latitude; 
    this._longitude = longitude; 
    this._radius = radius; 

    try { 

     HttpRequestFactory httpRequestFactory = createRequestFactory(HTTP_TRANSPORT); 
     HttpRequest request = httpRequestFactory 
       .buildGetRequest(new GenericUrl(PLACES_SEARCH_URL)); 
     request.getUrl().put("key", API_KEY); 
     request.getUrl().put("location", _latitude + "," + _longitude); 
     request.getUrl().put("radius", _radius); // in meters 
     request.getUrl().put("sensor", "false"); 
     if(types != null) 
      request.getUrl().put("types", types); 



     PlacesList list = request.execute().parseAs(PlacesList.class); 
     // Check log cat for places response status 
     Log.d("Places Status", "" + list.status); 
     return list; 

    } catch (HttpResponseException e) { 
     Log.e("Error:", e.getMessage()); 
     return null; 
    } 

} 

i Użyłem pozwolenie jak

ale otrzymuję błąd w LogCat jest

Answer 1

Jesteś nieszczelne okna. Należy wywołać pDialog.dismiss(); w metodzie onPostExecute() zadania asynchronicznego. Powinieneś również umieścić ...

if(pDialog != null) 
    pDialog.dismiss(); 

w Twojej onPause() metoda działania na wątku głównym. Spowoduje to, że okno nie wycieknie, nawet jeśli twoja aplikacja straci pierwszy plan podczas wykonywania niektórych prac w tle. Powinieneś mieć coś takiego ...

public class Login extends Activity implements View.OnClickListener{ 

    ProgressDialog pd; 

    public void onCreate(Bundle savedInstanceState){ 

     super.onCreate(savedInstanceState); 
     requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); 
     setContentView(R.layout.login); 
     pd = null; 
    } 

    @Override 
    public void onPause(){ 

     super.onPause(); 
     if(pd != null) 
      pd.dismiss(); 
    } 

    public void onClick(View v){ 
     new SendTask().execute(""); 
    } 

    /* 
    No networking allowed on the main thread. 
    */ 
    private class SendTask extends AsyncTask<String,String,String>{ 

     int result; 

     @Override 
     protected void onPreExecute(){ 
      pd = ProgressDialog.show(Login.this,"","Retrieving Inbox...", true,false); 
     } 

     @Override 
     protected String doInBackground(String...strings){ 

      //do networking here 
      result = account.prepare(); 
      return null; 
     } 

     @Override 
     protected void onPostExecute(String unused){ 

      //check result 
      pd.dismiss(); 
      Intent intent = new Intent(Login.this,NextActivity.class); 
      finish(); 
      startActivity(intent); 
     } 
    } 
} 

Answer 2

Próbujesz pokazać okno dialogowe po wyjściu z ekranu.

Answer 3

Użyj tego w OnStop --->

@Override 
    protected void onStop() { 

     super.onStop(); 

     if (pDialog != null) { 
      pDialog.dismiss(); 
      pDialog = null; 
     } 

    } 

Answer 4

Wystarczy zadzwonić Asynctask w IsNetworkAvailable() funkcji ... jak ...

if(isNetworkAvailable()) { 
     AsyncTask_WebAPI asyncTask = new AsyncTask_WebAPI(this, strURL, this); 
     asyncTask.execute(); 
    }else 
    { 
Toast.makeText(this,"Please Check internet Connectivity",Toast.LENGTH_LONG).show(); 
    } 

IsNetworkAvailable() Funkcja

private boolean isNetworkAvailable() { 
    ConnectivityManager connectivityManager 
      = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); 
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo(); 
    return activeNetworkInfo != null && activeNetworkInfo.isConnected(); 
} 

Answer 5

Musisz zamknąć okno dialogowe przed zniszczeniem aktywności

@Override 
protected void onDestroy() { 
    super.onDestroy(); 
    if(pDialog!=null && pDialog.isShowing()) 
     pDialog.dismiss(); 
}
