You are throwing a NetworkOnMainThreadException by performing network operations on your main Activity.
This is in place since Ice Cream Sandwitch.
Use an AsyncTask, Service, Handler, or in general, a background Thread to perform those operations.

Android application crashes after launch. Button issue?

I got problem with my first Android application. Just after running, my app crashes in emulator with "Unfortunately has stopped." message. I checked many threads on Stack and I read pretty much of official documentation and I really do not know what's a cause...
I use AVD with Android 4.4.2, API Level 19. CPU/ABI - ARM. Use Host GPU - checked (without this one emulator works very slowly).
My app should play a song after pressing the button. I would be really grateful for any ideas. Cheers.

You are working with fragments.
The Fragment cannot be added to the R.id.container View because it doesn't exists.
Just delete the whole if-clause in the onCreate() and also delete the Placeholder Class you don't need it actually.

Comment this code
/*if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment())
.commit();
}*/

Alert dialog not functioning correctly.

This code I am working on requires the user to press a button after entering a phone number into a text box. The button is made to save the number.
When I run the code I want to have it present the user with an alert dialog asking them to enter a number if they pressed the button with no number present.
Instead of getting the alert dialog the app crashes. But with a number entered the app works just fine.
Any advice on this would be awesome - Here is the code with the stack trace under that.
-Thank you!
b.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Create an if statement that brings up an alert dialog if there is no number entered into the field.
switch (v.getId()) {
case R.id.btnwidgetconfig: {
if (sharedData == null)
{
AlertDialog.Builder alert = new AlertDialog.Builder(c);
alert.setTitle("No number entered");
alert.setMessage("Please enter a phone number using the the text box");
alert.setCancelable(false);
alert.setPositiveButton("Okay", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
startActivityForResult(
new Intent(
android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS),
0);
}
});
}
else
{
String stringData = sharedData.getText().toString();
Long l = Long.parseLong(stringData);
SharedPreferences.Editor editor = prefs.edit();
prefs.edit().putLong(constants.KEY, l).commit();
Toast.makeText(c, "Your number has been saved!",
Toast.LENGTH_LONG).show();
svNum.setText("Saved Number: " + prefs.getLong(constants.KEY, 411));
break;
}
}
}
}
});

I'm guessing this sharedData is a TextView. Which you are still trying to parse the result when it is null, hence the NFE. Put in a check to only run that code if there is a valid number. You are checking if it is null, which the TextView may not be but the contents are an empty String which you are trying to parse
Change
if (sharedData == null)
to something like
if (sharedData == null || sharedData.getText().toString().equals(""))
{
...
I would try to get the text before that line into your stringData variable then check if that is empty. Also, you will want to put a try/catch around the parsing code in case they try to enter a non-digit and display a message, unless you've already done that

Android app crash when try to overwrite text in a TextView from other class

I try to change 3 textviews in a class called UserProfile() calling the method update() from the class UpdateProfile(), the class UserProfile do something like this:
package com.safm;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class UserProfile extends Activity {
TextView username, usersurname, useremail;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile);
username = (TextView) findViewById(R.id.username);
usersurname = (TextView) findViewById(R.id.usersurname);
useremail = (TextView) findViewById(R.id.useremail);
}
public void updateButton(View view){
Intent i = new Intent(this, UpdateProfile.class);
startActivity(i);
}
public void update(String nname, String nusername, String nemail){
System.out.println("2");
System.out.println(nname);
username.setText(nname);
usersurname.setText(nusername);
useremail.setText(nemail);
System.out.println("3");
}
}
The updateButton method invoke the UpdateProfile class:
package com.safm;

}

profile.update(nname, nsurname, nemail);
System.out.println("4");
Toast.makeText(this, "Success, the profile has been updated", Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(this, "You can't empty fields", Toast.LENGTH_SHORT).show();
}
}
This is my logcat file, as you can see, the first 2 flags are printed correctly, the error is when I try to set another text on the TextView, but the value of the strings (nname, nsurname and nemail) are not empty cause also is printed in the console HELP!

NOTE: I've clean the project and defined the TextView in ProfileUser class and the TextEdit in UpdateProfile outside the onCreate method but doesn't work.
Thanks.

Activities in Android are separate containers, that are in no way allowed to directly touch eachother. This is because the application stack behind Android 'freezes' the activities when they are no longer on the foreground, and could even be swapped to hard storage to save on RAM at the operating system's discretion.
Your UserProfile encapsulation should just reload its data after the UpdateProfile activity is closed, or request communication back the proper way via startActivityForResult.
Your current implementation is technically incorrect from each perspective, since you're hardcoding the UpdateProfile activity to always be called from a UserProfile activity. What if some day you introduce a new menu option to call it directly from the home screen? Activities are always separate, and should not make such assumptions.

Your getting a StrictMode violation. This means that you are doing something blocking on the UI Thread. Hence the reason for
android.os.NetworkOnMainThreadException
From the rest of your LOG it appears your performing a web request.
Make sure that HTTP request is wrapped in an AsyncTask (or something similar)

It seems like you are trying to do your login and registration on the main Thread. First of all this is bad practice, and it can't be done on recent API levels.
All you need to do is make your network connections in a separate thread, be it an AsyncTask or just a plain old Thread()
as an example :
use this
public void login()
{
new Thread(new Runnable() {
#Override
public void run() {
//your network connection goes here
}
}).start();
}
instead of :
public void login()
{
//your network connection goes here
}

Try to check the same in a mobile with internet connectivity.
The logcat also displays that the emulator doesnt has a GPS connectivity.
