Can't get Facebook ID and email

I faced with the following problem: I need to get FB id and email after authorization. Here's my code:
#Override
public void onSuccess(LoginResult loginResult) {
final String[] email = new String[1];
final String[] id = new String[1];
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
(object, response) -> {
try {
email[0] = object.getString(FB_EMAIL_PERMISSION);
id[0] = object.getString(FB_ID_PERMISSION);
} catch (JSONException e) {
e.printStackTrace();
}
response.getRawResponse();
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,email");
request.setParameters(parameters);
request.executeAsync();
Bundle bundle = new Bundle();
bundle.putString(EXTRA_TOKEN, loginResult.getAccessToken().getToken());
bundle.putString(EXTRA_EMAIL, email[0]);
bundle.putString(EXTRA_ID, id[0]);
mPresenter.saveUserData(bundle);
}
But when I run my app, I don't get this fields. I checked in debugger and part
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
(object, response) -> {
try {
email[0] = object.getString(FB_EMAIL_PERMISSION);
id[0] = object.getString(FB_ID_PERMISSION);
} catch (JSONException e) {
e.printStackTrace();
}
response.getRawResponse();
});
isn't called at all. I don't understand why it happens. So, what's the matter and how can I solve it?
UPD
Probably, maybe it would help, here's whole fb logic:
mCallbackManager = CallbackManager.Factory.create();
mFacebookButton.setReadPermissions(Collections.singletonList(FB_EMAIL_PERMISSION));
mFacebookButton.registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
final String[] email = new String[1];
final String[] id = new String[1];
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
(object, response) -> {
try {
email[0] = object.getString(FB_EMAIL_PERMISSION);
id[0] = object.getString(FB_ID_PERMISSION);
} catch (JSONException e) {
e.printStackTrace();
}
response.getRawResponse();
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,email");
request.setParameters(parameters);
request.executeAsync();
Bundle bundle = new Bundle();
bundle.putString(EXTRA_TOKEN, loginResult.getAccessToken().getToken());
bundle.putString(EXTRA_EMAIL, email[0]);
bundle.putString(EXTRA_ID, id[0]);
mPresenter.saveUserData(bundle);
}
UPD 2
I have one think about this problem, that request is asynchronous and when I put a breakpoint on line mPresenter.saveUserData(bundle); information isn't loaded yet, but how can I make it synchronous? Or maybe I am wrong?
UPD 3
I changed my request in the following way, but it still doesn't work and breakpoints are skipped in this part.
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
(object, response) -> {
try {
if (response.getJSONObject() != null) {
JSONObject data = response.getJSONObject();
if (data.has(FB_EMAIL_PERMISSION)) {
email[0] = response.getJSONObject().getString(FB_EMAIL_PERMISSION);
}
if (data.has(FB_ID_PERMISSION)) {
id[0] = response.getJSONObject().getString(FB_ID_PERMISSION);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
response.getRawResponse();
});
And here's the values of permissions:
private static final String FB_EMAIL_PERMISSION = "email";
private static final String FB_ID_PERMISSION = "id";

did you add permission to your facebook login button
fbLoginButton.setPermissions(Arrays.asList("public_profile,email,user_birthday"));

this is how i am using it
i am not sure of the value of FB_EMAIL_PERMISSION FB_ID_PERMISSION
final GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
try {
String id = "", user_email = "", name = "";
Log.d("EHREIUIU", String.valueOf(object));
if (response.getJSONObject() != null) {
JSONObject data = response.getJSONObject();
if (data.has("id"))
id = data.getString("id");
if (data.has("email"))
user_email = data.getString("email");
}
getOneSignalToken();
socialLogin(user_email, name, null, id, "facebook");
} catch (JSONException e) {
e.printStackTrace();
}
}
});

Activity keeps restarting when I leave the activity and come back to it

I have two activities, When I will move from activity A to B, B keeps restarting or "refreshing", when i go back from B to A, it also keeps restarting. The code is very big, here I am posting area where I think problem causes :
Thread t = new Thread(new Runnable() {
#Override
public void run() {
while (true) {
deviceStatus();
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
});
t.start();
this is deviceStatus();
public void deviceStatus(){
try {
RequestQueue requestQueue = Volley.newRequestQueue(InActivate.this);
String URL = "http://gickuwait-dev.com/electionapi/api/DeviceStatus";
JSONObject jsonBody = new JSONObject();
jsonBody.put("device_PK", device_ID2);
final String requestBody = jsonBody.toString();
StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if(response.equals("true")){
Intent intent = new Intent(InActivate.this, Vote.class);
startActivity(intent);
finish();
}else if(response.equals("false")) {
}
// Toast.makeText(getApplicationContext(), response.toString(), Toast.LENGTH_SHORT).show();
}
}, new Response.ErrorListener() {

return null;
}
}
#Override

String json = null;
try {
json = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
responseString = String.valueOf(json).trim();
ArrayList<DeviceStatusResponse> list = new ArrayList<DeviceStatusResponse>();
Type listType = new TypeToken<List<DeviceStatusResponse>>() {}.getType();
list = new Gson().fromJson(responseString, listType);
device_Status = list.get(0).getIsActive().toString();
// Toast.makeText(getApplicationContext(), ""+device_Status+" null ", Toast.LENGTH_LONG).show();
return Response.success(device_Status, HttpHeaderParser.parseCacheHeaders(response));
}
};
requestQueue.add(stringRequest);
} catch (JSONException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
in Activity B, i have the same code to check the device status from the database, any help would be appreciated

You can use Handle to check the repeated task.
private Handler delayHandler = new Handler();
private Runnable runnable = new Runnable() {
#Override
public void run() {
deviceStatus();
driverDelayHandler.postDelayed(runnable, 1000);
}
};
Don't forgot to cancel on onStop method.
delayHandler.removeCallbacks(runnable);

How to use interface as a Response Listener in android?

I have this code working with me, I am confused with the control flow.
How is the interface used here as a Response Listener? How is the overridden method responseObject(JSONObject resp, String type) in LoginActivity class triggering?
And after calling AsyncTask where the control goes?
public class LoginActivity extends Activity implements ResponseListener{
login = (Button) findViewById(R.id.btnLogin);
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
String username = mUsernameField.getText().toString();
String password = mPasswordField.getText().toString();
String[] param = {username, password};
new ServerRequests.LoginUserAsyncTask(LoginActivity.this,this).execute(param);
}
#Override
public void responseObject(JSONObject resp, String type) {
try{
if (resp.has("api_key")) {
String api_key = resp.getString("api_key");
String user_id = resp.getString("user");
Log.i("api_key", api_key);
SharedPreferences settings = LoginActivity.this.getSharedPreferences(Constants.NADA_SP_KEY, 0);
final SharedPreferences.Editor editor = settings.edit();
editor.putString(Constants.NADA_API_KEY, api_key);
editor.putString(Constants.NADA_USER_ID, user_id);
editor.putBoolean(Constants.NADA_IS_LOGGED_IN, true);
editor.commit();
Log.i("first Visit", "False");
String should_show_questions_screen = resp.getString("should_set_basic_questions");
if (should_show_questions_screen.compareToIgnoreCase("true")==0){
Intent intent=new Intent(LoginActivity.this,RegistrationSuccessfulScreen.class);
startActivity(intent);

//Here's Interface Which has this method
public interface ResponseListener {
public void responseObject(JSONObject data,String type);
}

Your LoginActivity implements ResponseListener. In this line: new ServerRequests.LoginUserAsyncTask(LoginActivity.this,this).execute(param);, you pass your activity twice into the LoginUserAsyncTask constructor. Notice that the constructor takes in a Context and a ResponseListener. You can do this because your activity implements ResponseListener.
Now LoginUserAsyncTask can call the responseObject method on your activty because it has a refrence to it as a ResponseListener. It does that in the onPostExecute method of the AsyncTask. The activity is kind of listning to when the task is done, then it's responseObject method is called.
Becaus the work of the AsyncTask is done asynchronously it returns "straight away" and the next statement is executed.
I also think your missing part of the first method.

Loading MAMP (Localhost) Data into EditText Issue Android

I've got a MAMP (localhost) database and have a profile loaded. I want to be able to load all my profile data so like 9 fields in my multi-line edit text.
There are no errors just my Log it shows success when it retrieves the data but it only displays one of the fields from the database and not all...Any idea how to get all? My php and everything else is fine as I've tested it.
I was wondering if you could help me?

You are over-writing the EditText field with each item.
To fix it, just create a StringBuilder and concatenate each item that is available.
Then, call txtMessage.setText at the bottom once you've extracted all of the data.
protected void onPostExecute(JSONObject product) {
if (product != null) {
// product with this pid found
// Edit Text
txtMessage = (EditText) findViewById(R.id.txtMessage);
StringBuilder jsonStringBuilder = new StringBuilder(); //Create StringBuilder for concatenation of JSON results
// display profile data in EditText
try {
//txtMessage.setText(product.getString(TAG_FIRSTNAME)); //Don't set the text here
jsonStringBuilder.append(product.getString(TAG_FIRSTNAME)); //Concatenate each separate item
jsonStringBuilder.append(System.getProperty("line.separator"));
} catch (JSONException e) {
e.printStackTrace();
}
try {
//txtMessage.setText(product.getString(TAG_LASTNAME));
jsonStringBuilder.append(product.getString(TAG_LASTNAME));
jsonStringBuilder.append(System.getProperty("line.separator"));
} catch (JSONException e) {
e.printStackTrace();
}
try {
//txtMessage.setText(product.getString(TAG_ADDRESS));
jsonStringBuilder.append(product.getString(TAG_ADDRESS));
jsonStringBuilder.append(System.getProperty("line.separator"));
} catch (JSONException e) {
e.printStackTrace();
}
try {
//txtMessage.setText(product.getString(TAG_COMMENTS));
jsonStringBuilder.append(product.getString(TAG_COMMENTS));
jsonStringBuilder.append(System.getProperty("line.separator"));
} catch (JSONException e) {
e.printStackTrace();
}
try {

jsonStringBuilder.append(product.getString(TAG_AGE));
jsonStringBuilder.append(System.getProperty("line.separator"));
} catch (JSONException e) {
