I'm using the code below to get some local video URL from an API.

public void getVideoAds(String serverURL)
 String url = "http://"+serverURL+"/video/";

 StringRequest stringRequest = new StringRequest(url, new Response.Listener<String>() 
 @Override
 public void onResponse(String response) 
 try 
 JSONObject jsonObj = new JSONObject(response);
 JSONObject defaultObj = jsonObj.getJSONObject("default");
 JSONArray videoObj = jsonObj.getJSONArray("videos");

 defaultUrl = defaultObj.getString("url");

 for (int i = 0; i < videoObj.length(); i++)
 JSONObject video = videoObj.getJSONObject(i);

 VideoAd v = new VideoAd();
 v.setName(getVideoNameFromLink(video.getString("url")));
 v.setUrl(video.getString("url"));
 v.setVideoId(video.getInt("id"));
 v.setVersion(video.getInt("version"));
 v.setLocalPath("");

 vidArrLst.add(v);
 

 playLoopVideo();
 catch (Exception e) 
 Log.d(TAG, "getVidAds res err: " + e.getMessage());
 

 
 , new Response.ErrorListener() 
 @Override
 public void onErrorResponse(VolleyError error) 
 Toast.makeText(ctx, "VideoAds Err: "+error.getLocalizedMessage(), Toast.LENGTH_LONG).show();
 Log.d(TAG, "getVidAds err: " + error.getMessage());
 
 );

 queue.add(stringRequest);

And inside onCreate(), I initialize RequestQueue like this.

queue = Volley.newRequestQueue(this);

Sometimes, getVideoAds() works. Sometimes, it doesn't work. The weird thing as well is that I'm not getting any error even after using Exception on my catch(). If it doesn't work, I do a Clean Project -> Rebuild Project -> Make Project and it works again. But after a few builds, mostly just 1 more build, it stops working again.

If you want to know more about playLoopVideo, look at this SO question I made. It's about the video playing part of my app. It currently doesn't play the video if I try to play it inside the onResponse of getVideoAds that's why I made a different question for it because maybe if I fix my Volley the video would play again.

This is my build.gradle(app) if you need it.

UPDATE:

This is really weird. My getVideoAds() method is called inside another method that calls a method the makes a StringRequest on a different API on the same server. To make it easier to understand below is the code for it.

private void getAdvertisements(final String serverURL)
 getVideoAds(serverURL);
 getMessageAds(serverURL);

 new android.os.Handler().postDelayed(
 new Runnable() 
 public void run() 
 Log.d(TAG, "Updating ads marquee");
 getMessageAds(serverURL);
 
 ,
 300000);

Currently, the API that getMessageAds() calls don't return anything. I tried to comment it and the handler below and it finally worked. Even the video playing worked. I then tried to uncomment getMessageAds() and add a few messages on the server, everything is working fine. But after I remove the messages, it stops working again.

What could be the reason for this to happen?

Add this in volley

 stringRequest.setRetryPolicy(DefaultRetryPolicy(20000, 3, 1.0f));
