Android studio Mail issue

I have set up classes in my app to send a mail based on the user's name email and message. It seems in app as if it's working fine but no actual email is being sent. Can Anybody help? Thank you in advance.
Here is the Gmail class i have set:
public class GMail {
final String emailPort = "587"; // this is gMail's smtp port number
final String smtpAuth = "true";
final String starttls = "true";
final String emailHost = "smtp.gmail.com";
String fromEmail;
String fromPassword;
List<String> toEmailList;
String emailSubject;
String emailBody;
Properties emailProperties;
Session mailSession;
MimeMessage emailMessage;
// this will be the constructor of the email
public GMail(String fromEmail, String fromPassword, List<String> toEmailList, String emailSubject, String emailBody)
{
this.fromEmail = fromEmail;
this.fromPassword = fromPassword;
this.toEmailList = toEmailList;
this.emailBody = emailBody;
//setting the server settings for Gmail
emailProperties = System.getProperties();
emailProperties.put("mail.smtp.port", emailPort);
emailProperties.put("mail.smtp.auth", smtpAuth);
emailProperties.put("mail.smtp.starttls.enable", starttls);
Log.i("Gmail", "Mail server properties are now set.");
}
public MimeMessage createEmailMessage() throws AddressException,
MessagingException, UnsupportedEncodingException{
mailSession = Session.getDefaultInstance(emailProperties, null);
emailMessage = new MimeMessage(mailSession);
emailMessage.setFrom(new InternetAddress(fromEmail, fromEmail));//address setup
for(String toEmail : toEmailList){
Log.i("GMail", "toEmail" + toEmail);
emailMessage.addRecipient(Message.RecipientType.TO,
new InternetAddress(toEmail));
}
emailMessage.setSubject(emailSubject); //email Subject
emailMessage.setContent(emailBody, "text/html");
return emailMessage;
}
public void sendEmail() throws AddressException, MessagingException
{
Transport transport = mailSession.getTransport("smtp");
transport.connect(emailHost, fromEmail, fromPassword);
Log.i("Gmail", "allrecipients: " + emailMessage.getAllRecipients());
transport.close();
Log.i("Gmail", "Your Email has successfully been sent.");
}
}
Here's my SendMailTask class
public class SendMailTask extends AsyncTask {
private ProgressDialog statusDialog;
private Activity sendMailActivity;
public SendMailTask(Activity activity) {
sendMailActivity = activity;
}
// make the method for showing dialog progress
protected void onPreExecute() {
statusDialog = new ProgressDialog(sendMailActivity);
statusDialog.setMessage("Setting up..");
statusDialog.setIndeterminate(false);
statusDialog.setCancelable(false);
statusDialog.show();
}
//method for creation and sending of email
#Override
protected Object doInBackground(Object... args) {
try{
Log.i("SendMailTask", "Setting up your email ..");
publishProgress("Processing all your information ..");
GMail androidEmail = new GMail(args[0].toString(),
args[1].toString(), (List) args[2], args[3].toString(),
args[4].toString());
publishProgress("Preparing your information ..");
androidEmail.createEmailMessage();
publishProgress("Sending your information ..");
androidEmail.sendEmail();
publishProgress("Information sent.");
Log.i("SendMailTask", "Information sent.");
}catch(Exception e){
publishProgress(e.getMessage());
Log.e("SendMailTask", e.getMessage(), e);
}
return null;
}
// creating method for dialog messages.
#Override
public void onProgressUpdate(Object... values){
statusDialog.setMessage(values[0].toString());
}
//method to get rid of the dialog message.
#Override
public void onPostExecute(Object result){
statusDialog.dismiss();
}
}
and here is the class that im trying to get the mail sent from:
public class HelpPage extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_help_page2);
final EditText mail1 = findViewById(R.id.email1);
final EditText mail2 = findViewById(R.id.email2);
final EditText nameIn = findViewById(R.id.hName1);
final Button btnSub = findViewById(R.id.helpBtn);
final EditText msgIn = findViewById(R.id.hMsg);
final String password = "xxxxxxxx";
final String sendemail = "come2gopj#gmail.com";
final String recemail = "c2grecieve#gmail.com";
final boolean connt;
ConnectivityManager connectivityManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
if(connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED ||
connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED){
// Connection affirmative:)
connt = true;
}
else {
connt = false;
Toast.makeText(getApplicationContext(), "You're not connected to the internet",
Toast.LENGTH_LONG).show();
}
btnSub.setOnClickListener(
arg0 -> {
//method to make sure all fields are checked
if(nameIn.getText().toString().equals("")||mail1.getText().toString().equals("")||mail2.getText().toString().equals("")||msgIn.getText().toString().equals(""))
{
Toast.makeText(getApplicationContext(), "Please check you've filled all fields.",
Toast.LENGTH_LONG).show();
}
else if(connt!=true){
Toast.makeText(getApplicationContext(), "You're internet connection needs to be checked",
Toast.LENGTH_LONG).show();
}
else{
if(mail1.getText().toString().equals(mail2.getText().toString())){
Log.i("SendMailActivity", "Send Button Clicked.");
//declaring the recieving, password and sending of the email
List<String> toEmailList = Arrays.asList(recemail.split("\\s*,\\s*")); //Recipient List
Log.i("SendMailActivity", "To List: " + toEmailList);
String emailSubject = ((EditText) findViewById(R.id.hName1)).getText().toString();
String emailEmail = ((EditText) findViewById(R.id.email1)).getText().toString();
String emailBody = "User's Email : " + ((EditText) findViewById(R.id.email1)).getText().toString() + "\n" +
"User's message: "+((EditText) findViewById(R.id.hMsg)).getText().toString();
new SendMailTask(HelpPage.this).execute(sendemail, password,toEmailList,emailSubject,emailBody,emailEmail);//send the email with all the relevant data included
startActivity(new Intent(getApplicationContext(),AfterMail.class)); //this will start the next activity that i have included after the mail is sent
}
else{//method for checking the email inputs
Toast.makeText(getApplicationContext(), "Your emails don't match please try again.",
Toast.LENGTH_LONG).show();
}
}
});
}
These are the messages i get in the run dialog after I've pressed the send button:
I/SendMailActivity: Send Button Clicked.I/SendMailActivity: To List: [c2grecieve#gmail.com]
I/SendMailTask: Setting up your email ..

I/Gmail: allrecipients: [Ljavax.mail.internet.InternetAddress;#80121b1
I/Gmail: Your Email has successfully been sent.I/SendMailTask: Information sent.

I finally figured out what I was missing. in the GMail.java file i was missing 1 line of code to get the email to actually send. `transport.sendMessage(emailMessage, emailMessage.getAllRecipients());
That was the line i was missing. `

TextToSpeech android API 22 not playing audio

I am using text to speech engine in my App. It works fine on emulator Nexus 6 with API 23 and higher. But on emulator Nexus 6 with API 22 it does not speak.
Both emulators use Pico TTS as preferred engine.
My activity layout contains only one button "Speak".
This is my activity code:
public class MainActivity extends AppCompatActivity {
private TextToSpeech mTTS;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button speakBtn = findViewById(R.id.button);
speakBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
speak();
}
});
mTTS = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
int result = mTTS.setLanguage(Locale.US);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "Language not supported");
}
mTTS.setOnUtteranceProgressListener(new UtteranceProgressListener() {
#Override
public void onStart(String utteranceId) {
Log.d("TTS", "onStart called, utteranceId = " + utteranceId);
}
#Override
public void onDone(String utteranceId) {
Log.d("TTS", "onDone called, utteranceId = " + utteranceId);
}
#Override
public void onError(String utteranceId) {
Log.d("TTS", "onError called, utteranceId = " + utteranceId);
}
});
} else {
Log.e("TTS", "Initialization failed");
}
}
});
}
private void speak() {
Log.d("TTS", "speak() method called");
HashMap<String, String> map = new HashMap<>();
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "greeting");
mTTS.speak("hello", TextToSpeech.QUEUE_FLUSH, map);
}
}
This is all logs from emulator Nexus 6 API 22:

Figured out how to solve the problem. Everything works if launch the emulator not via Debugging or Execution but from AVD Manager after starting Android Studio.

This is the activity in which i am using the class:

//postStringRequest(myserver.url + "/api/albums/getalbums.php", view);
AlbumsList albumsList = new AlbumsList(myserver.url+"/api/albums/getalbums.php",getContext(),view);
albumsList.connection(); // Do connection
Toast.makeText(getContext(),albumsList.imgsurls[1],Toast.LENGTH_LONG).show();
/*

*/
return view;
}
AlbumsList.java
public class AlbumsList {

Context mycontext;
public String[] imgsurls;
private View view;
AlbumsList(String serverurl, Context c,View uview){
mycontext = c;
server = serverurl;
view = uview;
}
public View connection(){
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(mycontext);
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.POST, server,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//GridView gv = (GridView)view.findViewById(R.id.fragment_gridgallery);
final ArrayList<String> urls2 = new ArrayList<String>();
try {
JSONArray jsonObj = new JSONArray(response);
Myserver myserver = new Myserver();
for (int i=0;i<jsonObj.length();i++){
JSONObject c = jsonObj.getJSONObject(i);
String imgurl = myserver.url+"/images/thumbs/tn_"+c.getString("album_thumbnail");
urls2.add(imgurl);
}
final String myabc[] = urls2.toArray(new String[urls2.size()]); //Do not remove this
imgsurls = myabc;
Toast.makeText(mycontext, imgsurls[0], Toast.LENGTH_LONG).show(); //Interestingly this toast works and imgsurls[] is ok
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(mycontext,e.getLocalizedMessage(),Toast.LENGTH_LONG).show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(mycontext, "Unable to reach server", Toast.LENGTH_LONG).show();
}
}) {
#Override

params.put("getalbum", "getalbum");
return params;
}
};
queue.add(stringRequest);
return view;
}
public String[] imgurls(){
return imgsurls;
}
}
In AlbumsList.java, I want to return the list of URLS by either a function or variables, but both approachs don't work. Interestingly the url's are fetched proper from database. And that Toast inside AlbumsList.java: Toast.makeText(mycontext, imgsurls[0], Toast.LENGTH_LONG).show(); also works. Then I don't know why the imgsurls is not returned to main function. Thanks in advance.

Because Volley request is asynchronous.
Thus when are you calling albumsList.connection();, the request is running in background and before it is completed, control comes to the following line:
Toast.makeText(getContext(),albumsList.imgsurls[1],Toast.LENGTH_LONG).show();
And by that time, your request is not completed.

Volley works in an asynchronous fashion. This means that it doesn't return the result of the operation immediately. You are trying to access the results before they are fetched from the server.
You should move your view initialisation logic to the onResponse(), when the result is actually being delivered.

Error in OnClick Script

myOnClickListener = new MyOnClickListener(this);
nRecyclerView = (RecyclerView) findViewById(R.id.my_recycler2_view);
nRecyclerView.setHasFixedSize(true);

this.context = context;
}

for (int i = 0; i < MyData.countryArray.length; i++){
if (selectedName==MyData.countryArray[i]) {
System.out.println(selectedName);
}
}
}
}
This has worked before, but isnt working now. Did I do anything wrong? I have 2 RecyclerViews but they are not visible together. This click listener is for one RecyclerView only.

Android: App crashes at getting text form editText in dialog

everytime i press the positive button of the dialog my app crashes with an nullpointerexception but i have no idea what i have to change. i think the problem is caused by the part with getText() because it works when i delete it here:
class newLessonDialog extends DialogFragment {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(inflater.inflate(R.layout.new_lesson_dialog, null))
// Add action buttons,
.setPositiveButton("Speichern", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id)
{
EditText eF = (EditText)getView().findViewById(R.id.editFach);
fach = eF.getText().toString();
EditText eR = (EditText)getView().findViewById(R.id.editRaum);
raum = eR.getText().toString();
EditText eL = (EditText)getView().findViewById(R.id.editLehrer);
lehrer = eL.getText().toString();
save(fach, raum, lehrer, index);
}
})
.setNegativeButton("Abbrechen", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
newLessonDialog.this.getDialog().cancel();
}
});
return builder.create();
}
}
and
public static void save(String fach, String raum, String lehrer, int index)
{
BufferedWriter out = null;
try
{
out = new BufferedWriter(new FileWriter("/sdcard/" + index + "fach.txt"));
out.write(fach);
out = new BufferedWriter(new FileWriter("/sdcard/" + index + "raum.txt"));
out.write(raum);
out = new BufferedWriter(new FileWriter("/sdcard/" + index + "lehrer.txt"));
out.write(lehrer);
out.close();
}
catch (Exception e)
{
Toast.makeText(getAppContext(), "Fehler beim Speichern!", Toast.LENGTH_SHORT);
}
}

Try replacing your getView()s with getDialog().
EditText eF = (EditText)getDialog().findViewById(R.id.editFach);
fach = eF.getText().toString();
EditText eR = (EditText)getDialog().findViewById(R.id.editRaum);
raum = eR.getText().toString();
EditText eL = (EditText)getDialog().findViewById(R.id.editLehrer);
lehrer = eL.getText().toString();

You may as well keep a reference to the original view; it'll make things a lot easier. Try:
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
final View view = inflater.inflate(R.layout.new_lesson_dialog, null);
builder.setView(view)
.setPositiveButton("Speichern", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
EditText eF = (EditText)view.findViewById(R.id.editFach);
...etc.
