In order to use push notifications you will need to do both server-side and client-side coding. Describing the whole process in detail would be too much for an SO answer, you should take a look at one of the many tutorials available online. Here's one to get you started.

I don't even know I am right are wrong. My situation of thinking is currently null. can some please tell me how to update deliverystatus
This is code in AdapterClass

#Override
public void onResponse(JSONObject response) {
Log.d("update delivery list",response.toString());
deliveryListBeans.clear();
notifyDataSetChanged();
}
}, new Response.ErrorListener() {

API work fine in POSTMAN but not work properly here.
try changing your Content-Type
application/json;charset=utf-8
to
application/json
I'm creating an IoT project through which I will be able to control home devices and utilities over internet. In the below code, it'll open a curtain when the switch is enabled. What I want to do here is to disable the button until the curtain is fully open which takes 5 seconds of time, so the user won't be able to press the button to close the curtain until it is fully open (because of limitations in servo motor). I've wrote the below code to accomplish this. It uses the Timer class. But it is not disabling the switch at all. Any help would be appreciated. Thanks!
curtain.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if (response.equals("open")) {
Toast.makeText(getApplicationContext(), "Curtain is opening..", Toast.LENGTH_LONG).show();
final long period = 5000;
new Timer().schedule(new TimerTask() {
#Override
public void run() {
curtain.setEnabled(false);
}
}, System.currentTimeMillis(), period);
curtain.setEnabled(true);
} else {
Toast.makeText(getApplicationContext(), "Failed to open", Toast.LENGTH_SHORT).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), "Connection failed. Please check your internet connection.", Toast.LENGTH_SHORT).show();
error.printStackTrace();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> getData = new HashMap<>();
getData.put("device", "curtain");
getData.put("action", "open");
return getData;
}
};
IotSingleton.getInstance(MainActivity.this).addToRequestQue(stringRequest);
}
Simply use Handler as below:
...
#Override
public void onResponse(String response) {
if (response.equals("open")) {
buttonView.setEnabled(false);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
buttonView.setEnabled(true);
}
}, 5000);
} else {
Toast.makeText(getApplicationContext(), "Failed to open", Toast.LENGTH_SHORT).show();
}
}
...
See if it works for you...!!
My app performs uploading operation to backend php server.My problem is i cannot dismiss the progressdialog inside volley Onresponse() method.Onresponse() method gets executed and toast is displayed in background of the Progressdialog so that means Onresponse() gets called currectly.
I declared ProgressDialog variable in public
onCreate() method look like this
ProgressDialog dialog;
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.signup);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
dialog=new ProgressDialog(context,ProgressDialog.STYLE_SPINNER);
dialog.setIndeterminate(true);
dialog.show(context,"Signing up","Please wait...");
login_call();
}
Login_call() performs volley request and inside the onResponse() i need to dismiss the dialog but its not working.
public void login_call()
{
RequestQueue queue= Volley.newRequestQueue(getApplicationContext());
StringRequest request = new StringRequest(Request.Method.POST, "http://192.168.56.1/sign.php", new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if (response.equals("success"))
{
dialog.dismiss();
getApplicationContext().startActivity(new Intent(getApplicationContext(), MainActivity.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
}
else
{
dialog.dismiss()
Toast.makeText(getApplicationContext(), response, Toast.LENGTH_LONG).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
dialog.dismiss();
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
}
}
) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> param = new HashMap<>();
param.put("user",user.getText().toString());
param.put("pass",pass.getText().toString());
param.put("name",name.getText().toString());
param.put("mob",mob.getText().toString());
param.put("email",email.getText().toString());
param.put("photo",photo);
return param;
}
};
queue.add(request);
}
Toast message is displaying correctly but progressdialog is not gettting dismissed.
Any ideas to solve the problem??
Just change this :
RequestQueue queue= Volley.newRequestQueue(getApplicationContext());
StringRequest request = new StringRequest(Request.Method.POST, "http://192.168.56.1/sign.php", new Response.Listener<String>() {
#Override
public void onResponse(String response) {
dialog.dismiss(); // write it there
if (response.equals("success")) {
// dialog.dismiss(); remove this from here..!!
getApplicationContext().startActivity(new Intent(getApplicationContext(), MainActivity.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
);
} else {
Toast.makeText(getApplicationContext(), response, Toast.LENGTH_LONG).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
dialog.dismiss();
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
}
}
Edit : set this
dialog.setIndeterminate(false);
first in first you didn't check all conditions
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if (response.equals("success")) {
dialog.dismiss();
getApplicationContext().startActivity(new Intent(getApplicationContext(), MainActivity.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
**} else {
Toast.makeText(getApplicationContext(), response, Toast.LENGTH_LONG).show();
}**
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
dialog.dismiss();
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
}
The else block doesn't hide the dialog so you should change it in this way
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
dialog.dismiss();
if (response.equals("success")) {
getApplicationContext().startActivity(new Intent(getApplicationContext(), MainActivity.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
} else {
Toast.makeText(getApplicationContext(), response, Toast.LENGTH_LONG).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
dialog.dismiss();
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
}
I think that the mistake is this, of course assuming that your dialog is accessible from the callback
Change your Dialog.show method to use this version: show(Context context, CharSequence title, CharSequence message, boolean indeterminate, boolean cancelable) like this:
final ProgressDialog dialog = ProgressDialog.show(context, "Signing up","Please wait...", false, true);
So your onClick code should change to something like this:
public void onClick(View view) {
final ProgressDialog dialog = ProgressDialog.show(context, "Signing up","Please wait...", false, true);
login_call();
}
Please give this a try and let me know if it helps.
I have two Volley requests. The first request authenticates the user; the second one gets data from the server.
If I send a GET request and the user is not authenticated, I want to fire the first request, authenticate the user and then keep executing the second one once the user is successfully authenticated.
So, the solution is pretty simple. :)
After I learned about callbacks and how them work, I figured out how to do that. So, I implemented a interface that declared the methods I wanted to invoke:
public interface AuthenticationCallback {
public void onLoginSuccess(String result);
public void onLoginError(String result);
}
public interface ResponseCallback {
public void onLoginSuccess(String result);
public void onAuthorizationError(String result);
}
My function:
public void getConversationMessages(final Context context, final String conversationID, final ResponseCallback responseCallback) {
final String url = GET_CONVERSATION_MESSAGES + conversationID;
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if (responseCallback != null) {
responseCallback.onLoginSuccess(response);
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
if (error.networkResponse != null && error.networkResponse.statusCode == HttpURLConnection.HTTP_UNAUTHORIZED){
if (responseCallback != null) {
responseCallback.onAuthorizationError(error.getMessage());
}
}
}
})
{
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Cookie", AppSingleton.getInstance(context).getCookie());
headers.put("Content-Type", "application/json");
return headers;
}
};
AppSingleton.getInstance(context).getRequestQueue().add(stringRequest);
}
}
My Activity:
ServerConnection.getInstance().getConversationMessages(getApplicationContext(), id, new ResponseCallback() {
#Override
public void onLoginSuccess(String result) {
}
#Override
public void onAuthorizationError(String result) {
ServerConnection.getInstance().loginFunction(getApplicationContext(), userID, new AuthenticationCallback() {
#Override
public void onLoginSuccess(String result) {
ServerConnection.getInstance().getConversationMessages(getApplicationContext(), conID, new ResponseCallback() {
#Override
public void onLoginSuccess(String result) {
}
#Override
public void onAuthorizationError(String result) {
}
});
}
#Override
public void onLoginError(String result) {
}
});
}
});
Basically, the code will try to send a GETrequest. If the user is not authenticated, then it will execute the code at onAuthorizationError(), that will authenticate the user. Once the user is successfully authenticate, it will send the GET request again.
I think nesting callbacks like this is not a good practice, but I'll fix it later and update my answer.
If someone have a better way to implement that, please, post another answer!
You can put one volley method inside another, as soon as the first request gets finished it sends the another request.By doing this the data will be sent to the database and the same modified data can be fetched again. The code is as shown below.
StringRequest stringRequest = new StringRequest(Request.Method.POST, "YOUR_FIRST_URL", new Response.Listener < String > () {
#Override
public void onResponse(String response) {
StringRequest stringRequests = new StringRequest(Request.Method.POST, "YOUR_SECOND_URL", new Response.Listener < String > () {
#Override
public void onResponse(String response) {
try {
JSONArray genreArry = new JSONArray(response);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
protected Map < String, String > getParams() {
Map < String, String > params = new HashMap < String, String > ();
return params;
}
};
int socketTimeouts = 30000;
RetryPolicy policys = new DefaultRetryPolicy(socketTimeouts, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
stringRequests.setRetryPolicy(policys);
RequestQueue requestQueues = Volley.newRequestQueue(context);
requestQueues.add(stringRequests);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
protected Map < String, String > getParams() {
Map < String, String > params = new HashMap < String, String > ();
return params;
}
};
int socketTimeout = 30000;
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
stringRequest.setRetryPolicy(policy);
RequestQueue requestQueue = Volley.newRequestQueue(context);
requestQueue.add(stringRequest);
