I have a problem with old devices , when the data is sent to the server using an old device api 15 + 16 + 17 in Spanish or Portuguese, question marks will appear, and the new devices have no problems
txt_ok.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(edit_post.length() > 0)
{
txt_ok.setVisibility(View.GONE);
pd_newpostloading.setVisibility(View.VISIBLE);
String url = Information.URL_AddPendingPosts + Information.userid + "&authorname=" + Information.username + "&message=" + edit_post.getText().toString() + "&type=" + edit_category.getText().toString() + "&date=" + nowAsString;
try {
encodedValue = URLEncoder.encode(url,"UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
RequestQueue requestQueue = Volley.newRequestQueue(ShowMessages.this);
StringRequest stringRequest = new StringRequest(Request.Method.GET, encodedValue, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
txt_ok.setVisibility(View.VISIBLE);
pd_newpostloading.setVisibility(View.GONE);
Toast.makeText(ShowMessages.this, "Done", Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
txt_ok.setVisibility(View.VISIBLE);
pd_newpostloading.setVisibility(View.GONE);
Toast.makeText(ShowMessages.this, "Failed", Toast.LENGTH_SHORT).show();
}
});
requestQueue.add(stringRequest);
}
else
{
Toast.makeText(ShowMessages.this, "Empty", Toast.LENGTH_SHORT).show();
}
}
});
I hope to get some help thanks in advance :)

I have this issue with Volley library requests. I make calls to API and since they have to be updated very often I implemented timers. After some time it throws me error:"Throwing OutOfMemoryError “pthread_create (1040KB stack) failed: Try again. I used the method which was suggested in this post: Throwing OutOfMemoryError "pthread_create (1040KB stack) failed: Try again" when doing asynchronous posts using Volley , but for me it did not work, the data coming from API stopped updating. I thought it might be something with timers or it is just something I am doing wrong using Volley.
If you have any idea, feel welcome to share.
My printer class
public void setMenuInformation(String url, Context context, final VolleyCallback callback) {
Log.d("API", "Currently calling URL " + url);
if (eRequestQueue == null) {
eRequestQueue = Volley.newRequestQueue(context);
eRequestQueue.add(new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
String temp = response.substring(2, response.length() - 2);
Log.d("API", "Current menu" + response);
byte msgArray[];
try {
msgArray = temp.getBytes("ISO-8859-1");
currentMenu = msgArray[0];
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
menuInformation = response;
callback.onSuccess(menuInformation);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("API", "Current menu Nope ");
callback.onFailure(error);
}
}));
}
}
Main Activity:
myPrinterDetails.setMenuInformation("http://" + nsdServiceInfo.getHost() + "/GetCurrentMenu",
MainActivity.this, new PrinterNew.VolleyCallback() {
#Override
public void onSuccess(String result) {
runOnUiThread(new Runnable() {
#Override
public void run() {
Log.d("NSD", "Current menu response succeded and added to array " + nsdServiceInfo);
//services.add(myPrinterDetails);
mAdapter.notifyDataSetChanged();
}
});
Log.d("NSD", "CurrentMenu " + myPrinterDetails.getMenuInformation());
myTimer.schedule(new TimerTask() {
#Override

I'm developing a chat with firebase. Actually I'm sending audios between devices, saving it on the Storage ("new_audio"+number+".mp3") and saving that number on the Realtime Database (To know what was the last audio sended)
With the following code I can get the last number, and after that (when is uploading an audio) give him 1 more (number++).
When I start the chat with an user, the number is retrieved with out problems, but when the chat is open and User1 send an audio (new_audio3.mp3) and User2 send another audio after this dont retrieve the Number(Use the same audio number! new_audio3.mp3). In short, the updated number is not received at the same time by the other device, it works just when the chat was recently opened.
String audiosURL = "https://xxxxx.firebaseio.com/audios/" + UserDetails.username + "_" + UserDetails.chatWith +"/audiosEnviados.json";

I hope someone knows how to receive the number each time an audio is received / sent in the chat, THANKS <3!

I am a new developer in android.
I looked at the sources and made the parse from one link. But I have four links. How do I parse the four links?
Instead of having a String url, create an ArrayList of Strings that holds all your URLs.
In the method onClick() loop through the URLs.
Note that the ArrayList is filled in onCreate. I also added a try/catch clause in onClick, so if something goes wrong with one URL, the others will be parsed anyways.
Handling different URLs:
For parsing the Koinim ticker, you needed the key "sell", for Paribu you will need "last".
In the loop I am checking if the URL contains either Koinim or Paribu and adjust they key accordingly.
ArrayList<String> urls = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button) findViewById(R.id.btn_get_information);
price = (TextView) findViewById(R.id.price);
urls.add("https://koinim.com/ticker/");
urls.add("url2");
urls.add("url3");
urls.add("url4");
btn.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (v.getId() == R.id.btn_get_information) {
for (String url : urls) {
try {
JsonObjectRequest request = null;
if(url.contains("koinim"))
{
request = getSellPrice("sell");
}
else if(url.contains("paribu"))
{
request = getSellPrice("last");
}
if(request != null)
{
MySingleton.getmInstance(getApplicationContext()).
addToRequestQue(jsonObjectRequest);
}
} catch (Exception ex) {
// something went wrong, handle exception here
}
}

private JsonObjectRequest getSellPrice(String key)

JsonObjectRequest jsonObjectRequest = new
JsonObjectRequest(Request.Method.GET, url, null,

#Override

I am new to firebase. I tried to store user data in firebase database using volley. However, firebase has no response regarding my volley request and the database still is null. This is the tutorial I followed.
This is the volley request I used to connect firebase.
public void executeFirebase(){
StringRequest request = new StringRequest(Request.Method.GET, FIREBASE_REGISTER_URL, new Response.Listener<String>(){
#Override
public void onResponse(String s) {
Firebase reference = new Firebase("https://tradeal-930ad.firebaseio.com/users");
if(s.equals("null")) {
reference.child(name).child("password").setValue(password);
Toast.makeText(activity, "registration successful 1", Toast.LENGTH_LONG).show();
}
else {
try {
JSONObject obj = new JSONObject(s);
if (!obj.has(name)) {
reference.child(name).child("password").setValue(password);
Toast.makeText(activity, "registration successful 2", Toast.LENGTH_LONG).show();
Intent intent = new Intent(activity, MainPageActivity.class);
activity.startActivity(intent);
activity.finish();
loginUserActivity.finish();
} else {
Toast.makeText(activity, "username already exists", Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
loading.dismiss();
}
},new Response.ErrorListener(){
#Override
public void onErrorResponse(VolleyError volleyError) {
System.out.println("" + volleyError );
loading.dismiss();
}
});
RequestQueue rQueue = Volley.newRequestQueue(activity);
rQueue.add(request);
}
change the rules of your database to public
{
"rules" :
{
".read" : true,
".write" : true
}
}
otherwise
{
"error" : "Permission denied"
}
this will be your response
to know more about rules you can visit security rules
