Can I do a synchronous request with volley?

Imagine I\'m in a Service that already has a background thread. Can I do a request using volley in that same thread, so that callbacks happen synchronously?

You achieve this with kotlin Coroutines

implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.7"
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.7"

private suspend fun request(context: Context, link : String) : String{
   return suspendCancellableCoroutine { continuation ->
      val queue = Volley.newRequestQueue(context)
      val stringRequest = StringRequest(Request.Method.GET, link,
         { response ->
            continuation.resumeWith(Result.success(response))
         },
          {
            continuation.cancel(Exception("Volley Error"))
         })

      queue.add(stringRequest)
   }
}

And call with

CoroutineScope(Dispatchers.IO).launch {
    val response = request(CONTEXT, "https://www.google.com")
    withContext(Dispatchers.Main) {
       Toast.makeText(CONTEXT, response,Toast.LENGTH_SHORT).show()
   }
}
