• How to properly call releaseNetworkRequest(PendingIntent) when PendingIntent is no longer available

  I am trying to request the network, so I build the NetworkRequest and I build the PendingIntent,

  ConnectivityManager conn_manager =  (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
  
          NetworkRequest net_req;
          net_req = new NetworkRequest.Builder()
                  .addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR)  //Data Network?
                  .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)  //Wifi
                  .addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)  //This might be what need internet permission
                  .addCapability(NetworkCapabilities.NET_CAPABILITY_MMS)
                  .build();
  
          Intent intent_sent = new Intent(activity, Service_MmsNetworkAvailable.class);
  
          PendingIntent pending_intent_net_req_received = PendingIntent.getService(activity, 0, intent_sent,
                  PendingIntent.FLAG_ONE_SHOT);
  
          conn_manager.requestNetwork(net_req, pending_intent_net_req_received);
  

  Then once the Service runs from the PendingIntent calling it, I am doing some Network stuff inside the Service and then when I'm done I believe I need to call releaseNetworkRequest(PendingIntent).

  But here's the whole problem of mine, how do I reference the PendingIntent that started the Service from inside the Service? There is no guarantee that the Activity that created the NetworkRequest and PendingIntent will still be alive so I cannot rely on returning to that Activity to be able to call releaseNetworkRequest(PendingIntent) where I have reference to the PendingIntent.

  Android specifically states that you must pass in the same PendingIntent into releaseNetworkRequest(PendingIntent) that you passed into conn_manager.requestNetwork(net_req, pending_intent_net_req_received);

  So how is a developer supposed to releaseNetworkRequest(PendingIntent)?

  Can I somehow reference the PendingIntent from the Service? I understand that PendingIntents stay alive even after the Activity that called it parishes into the abyss.

  I must be missing something here, PendingIntents call Activities, Receivers, and Services, none of which I see can reference back to the original PendingIntent. Furthermore, NULL cannot be passed into releaseNetworkRequest(PendingIntent) according to Android documentation?

  Also just to note, I am only doing this because startUsingNetworkFeature() is deprecated and developers are encouraged to use NetworkRequest(), arg!!!

  I am literally stuck here now with no way to go, this is rare to be so backed into a corner here if anyone can shed light on this predicament of mine I would be grateful.

• iOS builds (ipa file) generated by Expo is too large

  I'm using Expo for a react native project. I used to get apk and ipa files close to 30 MB when I use exp build:android and exp build:ios. Recently I updated exp version to 53.0.0 and added an iPhone X to my Apple developer account. Since then I'm getting ipa file size above 170MB. I have not made any changes to my code or app.json. Does anyone have any idea why this is happening?

  I know this doesn't matter when I upload to App Store or Test Flight, but this is not an option for my project since we are using enterprise distribution and Diawi for testing purposes.

• Android loginvia facebook in pinterest is not working in webview

  Android - Am loading a following url in webview "https://www.pinterest.com", it loads successfully, but when i click on login via facebook or login via google in pinterest it's loading a blank screen rather than loading the actual result, below is my code, please help me. The same code is working for other urls, but not for Pinterest alone.

  public class Pinterest extends Fragment {
  
  private WebView wv1;
  String url="https://www.pinterest.com";
  private ProgressBar progress;
  View mView;
  WebSettings settings;
  ImageView back,top;
  public Pinterest() {
      // Required empty public constructor
  }
  
  @Override
  public void onCreate(@Nullable Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setHasOptionsMenu(true);
  }
  
  
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
                           Bundle savedInstanceState) {
      // Inflate the layout for this fragment
      mView= inflater.inflate(R.layout.pinterest, container, false);
      wv1 =  mView.findViewById(R.id.pin_webView);
      progress = mView.findViewById(R.id.pin_progressBar);
      back= mView.findViewById(R.id.go_back);
      top= mView.findViewById(R.id.goToTop);
      progress.setMax(100);
      settings = wv1.getSettings();
      settings.setJavaScriptEnabled(true);
      settings.setAllowContentAccess(true);
      settings.setDomStorageEnabled(true);
      wv1.setWebViewClient(new myWebClient());
      wv1.setVerticalScrollBarEnabled(true);
      wv1.setHorizontalScrollBarEnabled(true);
      wv1.loadUrl(url);
      progress.setProgress(0);
      wv1.setWebChromeClient(new WebChromeClient() {
          @Override
          public void onProgressChanged(WebView view, int newProgress) {
              setValue(newProgress);
              if (newProgress == 100) {
                  progress.setVisibility(View.GONE);
              }
              super.onProgressChanged(view, newProgress);
          }
      });
      back.setOnClickListener(v -> {
          if(wv1.canGoBack())wv1.goBack();
      });
  
      top.setOnClickListener(v -> {
          Constants.goTop(wv1);
      });
      return mView;
  }
  public void setValue(int progress) {
      this.progress.setProgress(progress);
  }
  
  
  
  public class myWebClient extends WebViewClient {
      @Override
      public void onPageStarted(WebView view, String url, Bitmap favicon) {
          // TODO Auto-generated method stub
          super.onPageStarted(view, url, favicon);
      }
  
      @Override
      public boolean shouldOverrideUrlLoading(WebView view, String url) {
          // TODO Auto-generated method stub
  
          System.out.println("when you click on any interlink on webview that 
      time you got url :-" + url);
      //            view.loadUrl(url);
          return false;
  
      }
  
      @Override
      public void onPageFinished(WebView view, String url) {
          System.out.println("your current url when webpage loading.. finish" 
      + url);
          super.onPageFinished(view, url);
           }
  
  
         }
