First off, please excuse my attempt at trying to solve the problem I'm about to describe.
Problem: I have two search fields, 1) "Enter Origin Address" and 2) "Enter Destination Address". Within these fields, a user can enter an address and the Google Places API launches to present various predicted addresses from which the user can make a selection. My issues is that after the user selects an "Origin" address, both search fields are populated (instead of just the "Origin" field).
Here is my code. Again, please excuse my ignorance, particularly with the fillinAddress2 method...

The problem: In Android, when I set the language for Google text to speech to Spanish, the spoken text is with an English voice. (a) Why isn't it in a Spanish "voice", and (b) If my code isn't correct, what more do I need to do to make it speak with a Spanish voice.
The English voice it uses means that "hola mundo" sounds like "howlaa mundow", as if an English person was trying to say the letters. This means the voice synthesizer being used is an English one (happens to be female). I can understand it, but all the Spanish vowel sounds and a few consonants (like the fact that "h" isn't pronounced) are wrong.
Here is a minimal version of my code which produces this error. I am using a Nexus 5X API 26 emulator. The code seems to think the text to speech engine is installed, and speech is synthesized, but with the error mentioned above. In the method "onInit()" (a callback which runs as soon as the Engine is loaded) I have asserted that the Locale for Spain exists. Therefore, the code won't play the voice if this isn't installed, so the fact I hear anything at all means the code believes it is "speaking in Spanish".
(Please note: This code has been updated to check the return values of setLanguage in a switch to make sure the language really was set correctly - and it is)

Good day all i am using android studio, I have a fairly good idea of how to use sugar ORM at this point, but there's one thing that I just cant find or figure out.
So i have an activity named UserProfiles.java in which i ask the user for various things and then i store them in the database. So at this point i have about 20 records/rows in the database. The problem however is when i send the user to the next activity (UserPins.java) i ask them to set some additional information now how do i add this information to the same line as the data that has the User Profiles information?
//this is my UserProfiles.java
package com.chika.mia;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import com.chika.mia.models.Mia;
public class UserProfile extends AppCompatActivity implements View.OnClickListener {
private EditText Name, PhoneNumber, Email, Password, Address;
private Button SaveUser;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_profile);
Name = (EditText)findViewById(R.id.Name);
PhoneNumber = (EditText)findViewById(R.id.PhoneNumber);
Email = (EditText)findViewById(R.id.Email);
Password = (EditText)findViewById(R.id.Password);
Address = (EditText)findViewById(R.id.Address);
SaveUser = (Button)findViewById(R.id.SaveUser);
SaveUser.setOnClickListener(this);
}
#Override
public void onClick(View v) {
Mia m = new Mia();
m.setName(register.g);
m.setPhoneNumber(Integer.parseInt(PhoneNumber.getText().toString())) ;
m.setEmail(register.i) ;
m.setPassword(register.h);
m.setAddress(Address.getText().toString()) ;
m.setLocation("MiaL");
m.setWipePhone("MiaWP");
m.setDispMessage("MiaDM");
m.setAlarm("MIAA");
m.setShutdown("MIASD");
m.save();
Toast.makeText(this, " " + m.getName(), Toast.LENGTH_LONG).show();
Intent intent = new Intent(UserProfile.this, UserPins.class);
startActivity(intent);
}
}
And this is my Userpins.java
package com.chika.mia;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.EditText;
import com.chika.mia.models.Mia;
import com.orm.query.Condition;
import com.orm.query.Select;
public class UserPins extends AppCompatActivity implements View.OnClickListener {
private EditText UserLocation,UserWipePhone,UserDisplayMsg,UserAlarm,UserShurdown;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_pins);
UserLocation = (EditText)findViewById(R.id.UserLocation);
UserWipePhone = (EditText)findViewById(R.id.UserWipePhone);
UserDisplayMsg = (EditText)findViewById(R.id.UserDisplayMsg);
UserAlarm = (EditText)findViewById(R.id.UserAlarm);
UserShurdown = (EditText)findViewById(R.id.UserShutdown);
}
#Override
public void onClick(View v) {
Mia m = new Mia();
Select.from(Mia.class).where(Condition.prop("Name").eq(register.i)).list();
m.setLocation(UserLocation.getText().toString());
m.setWipePhone(UserWipePhone.getText().toString());
m.setDispMessage(UserDisplayMsg.getText().toString());
m.setAlarm(UserAlarm.getText().toString());
m.setShutdown(UserShurdown.getText().toString());
m.update();
Intent intent = new Intent(this,AppSettings.class);
startActivity(intent);
}
}
What am aiming to do is something like this, So for which ever user logs in say "Tom", i already have the login and registration page sorted out. It will go through the database and look for the name "Tom" or email "tom#gmail.com" and then add the userpins information to the appropriate column in that table.
When you create a new record in Sugar ORM, you get a unique ID back from the save(). On your first activity, get the ID, and pass it to the next activity:
long new_user_id = m.save();
...
Intent intent = new Intent(UserProfile.this, UserPins.class);
intent.putExtra("NEW_USER_ID", new_user);
startActivity(intent);
Then you can grab it in the new activity with:
long new_user_id = getIntent().getLongExtra("NEW_USER_ID",0);
You may then use the ID to get the record to update:
Mia m = Mia.findById(Mia.class, new_user_id);
The MainMenu class keeps throwing an error on a String that says its null and I am having the hardest time figuring this out.

Problem lies here :
if ("New Recipe" != SelectedRecipe) {
Comparing string like this is only comparing the Object type, not the String value itself.
I'm making a wild guess that the SharedPreferences SelectedRecipe_Detail does not exist.
Hence, NPE is thrown when you are trying to getString() from it.
Solution :
Do your checking as below :
if(!"New Recipe".equals(SelectedRecipe)) {
Found the problem
You are using SelectedRecipe as constant
public static String SelectedRecipe = "SelectedRecipe";
and then you are updating its value in
SelectedRecipe = selectedRecipe.getString(MainMenu.SelectedRecipe, "New Recipe");
then you are using it again which makes it wrong
SharedPreferences thisRecipe = getSharedPreferences(SelectedRecipe + "_Detail", RecipeEntry.MODE_PRIVATE);
Change below code
String SelectedRecipe = selectedRecipe.getString(MainMenu.SelectedRecipe, "New Recipe");
if ("New Recipe" != SelectedRecipe) {
to
String retSelectedRecipe = selectedRecipe.getString(MainMenu.SelectedRecipe, "New Recipe");
if (!"New Recipe".equals(retSelectedRecipe) ) {
I think I know what the problem is.
I got this book:
The Complete Idiots Guide to Android App Development
This was released in 2011 and I am pretty sure things have changed since then.
I recommend that you DO NOT GET THIS BOOK!!! WARNING!!!
This Book is VERY POORLY MADE!!!
Through out the whole book the variables change and things get switch around and not just that, he does not specify a lot of important detail about anything. It is very Half Assed!!!
I am trying to develop a twitter client using android. My entire code is error free for now excepting the line " signIn.setOnClickListener(this);". I've tried following every other suggestion but they don't seem to help. The error reported is "The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (startingpoint)". According to suggestions it seems i should use "View" instead of "signIn". What could be the possible explanation and where do i need to correct my code?

this is because the interface your activity implements is wrong!

...
public class startingpoint extends Activity implements OnClickListener {
you should implements this interface View.OnClickListener.
I'm attempting to implement Google Analytics into my Android application however I'm following the example and it's giving me createAppView cannot be resolved or is not a field. I presume this is because it is not defined - but shouldn't it be defined in the example from google? I wouldn't expect them to make this kind of mistake and I have a feeling I'm doing something wrong on my end.

It's a typo within the example provided by Google. Actually, createAppView is a method and not variable, then:
StartActivity.getGaTracker().send(MapBuilder.createAppView.build());
should be:
StartActivity.getGaTracker().send(MapBuilder.createAppView().build());
Instead of MapBuilder.createAppView, it should be HitBuilders.ScreenViewBuilder() in Google Analytics API v4
replace
StartActivity.getGaTracker().send(MapBuilder.createAppView().build());
to
StartActivity.getGaTracker().send(HitBuilders.ScreenViewBuilder().build());
