Use date to manage subscriptions. Android. Firebase

My problem is with this activity. I want to get the time, compare it to the time on the database, and then if the subscription hasnt expired show a button, if it has hide it. Plus i want to show the credits a user has, and image and his name on top. I have tried many things, but it keeps crashing for some reason.
public void getthedate(){
calendar = Calendar.getInstance();
final SimpleDateFormat mdformat = new SimpleDateFormat("yyyy / MM / dd ");
// strDate = "Current Date : " + mdformat.format(calendar.getTime());
// futurecal = Calendar.getInstance();
// futurecal.add(Calendar.DATE, 30);
// futuredate = mdformat.format(futurecal.getTime());
DatabaseReference subtime = mDatabase.child("users").child(univ).child(uid);
subtime.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot dataSnapshot) {
subtimedate = dataSnapshot.child("subdate").getValue().toString();
String username = dataSnapshot.child("Full name").getValue().toString();
String coinstring = dataSnapshot.child("coins").getValue().toString();
coinview.setText(coinstring);
String imglink = dataSnapshot.child("imageuri").getValue().toString();
Glide.with(c).load(imglink).into(userthing);
hellostring.setText("Hey" + username + "!");
Date subdatecal = null;
try {
subdatecal = mdformat.parse(subtimedate);
} catch (ParseException e) {
e.printStackTrace();
}
Calendar newestcal = Calendar.getInstance();
newestcal.setTime(subdatecal);
if (newestcal.after(mdformat.format(calendar.getTime()))){
substat.setText("Active");
substat.setBackgroundColor(Color.GREEN);
//do something if subscription hasnt expired
}else{
gotonotes.setVisibility(View.GONE);
substat.setText("Expired");
substat.setBackgroundColor(Color.RED);
}
}
#Override
public void onCancelled(#NonNull DatabaseError databaseError) {
}
});
/*
DatabaseReference subtime = mDatabase.child("users").child(univ).child(uid).child("subdate");
subtime.setValue(futuredate);
set new subscription
*/
/* if (calendar.after(futurecal)){
use this to check if date has passed
}*/
}
In the oncreate i have setup everything.
substat = (TextView) findViewById(R.id.substat);
hellostring = (TextView) findViewById(R.id.hellostring);
coinview = (TextView) findViewById(R.id.coinview);
userthing = (ImageView) findViewById(R.id.userimagething);
mDatabase = FirebaseDatabase.getInstance().getReference();
friendbtn = (Button) findViewById(R.id.friendsbtn);
uid = FirebaseAuth.getInstance().getCurrentUser().getUid();
Thanks for any suggestions!

MediaPlayer music Android Studio

Just wanted to see if anyone could help me out or point me in the right direction. I'm learning how to make a simple music player where the user clicks on list view items and it streams the mp3. There's a play button up top and next and previous song buttons (haven't added seek functionality yet). However it keeps crashing when I select new song. Here's my activity code:
public class AudioActivity extends AppCompatActivity {
ListView listView;
ArrayList<String> musicList;
ArrayAdapter adapter;
MediaPlayer player;
ImageButton prev;
ImageButton play;
ImageButton next;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_audio);
prev = (ImageButton) findViewById(R.id.previous);
play = (ImageButton) findViewById(R.id.play);
next = (ImageButton) findViewById(R.id.next);
listView = findViewById(R.id.musiclist);
musicList = new ArrayList<>();
musicList.add("song");
musicList.add("song1");
musicList.add("song2");
musicList.add("song3");
musicList.add("song4");
adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1, musicList);
listView.setAdapter(adapter);
player = new MediaPlayer();
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch (position){
case 0:
String url = "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3";
try {
player.stop();
//player.release();
player.setDataSource(url);
} catch (IOException e) {
e.printStackTrace();
}
try {
player.prepare();
} catch (IOException e) {
e.printStackTrace();
}
break;
case 1:
url = "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-8.mp3";
try {
player.stop();
//player.release();
player.setDataSource(url);
} catch (IOException e) {
e.printStackTrace();
}
try {
player.prepare();
} catch (IOException e) {
e.printStackTrace();
}
break;
default:
break;
}
player.start();
}
});
}
public void onPlayBtnClicked(){
if(!player.isPlaying())
{
player.start();
}else
{
player.pause();
}
}
}

Unexpected status line while getting response from server on android app

I am establishing server-client communication between Android app and ESP8266 NodeMCU-1.0. The ESP is creating server on specified network and the mobile is connecting to same network.
For testing purpose I am sending "try123" string when the send button is pressed. And receiving appropriate response on the serial monitor of IDE (i.e. data is received on server). But the server response which is "Test_successful" string. I am sending this string to client using client.print. In app I am toasting the server response.
The problem is that if I am making the HTTP request using browser using the locally generated URL, then the response "Test_successful" is visible. But In app toast it's showing empty and while debugging it's showing error Unexpected line status.
ESP code (server side):
#include <ESP8266WiFi.h>
const char* ssid = "DARSHAN95";
const char* password = "12345678";
//const char* ssid = "TP-LINK_42C148";
//const char* password = "";
// Create an instance of the server
// specify the port to listen on as an argument
WiFiServer server(80);
void setup() {
Serial.begin(115200);
delay(10);
// Connect to WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
// Start the server
server.begin();
Serial.println("Server started");
// Print the IP address
Serial.println(WiFi.localIP());
}
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
Serial.println("new client");
while(!client.available()){
delay(1);
}
// Read the first line of the request
String req = client.readStringUntil('\r');
Serial.println(req);
client.flush();
// Match the request
//client.flush();
delay(100);
// Send the response to the client
client.print("Test_Sucessfull");
delay(200);
Serial.println("Client disonnected");
}

Intent is not starting a new Activity

public void onClick(View v) {
Toast.makeText(MainActivity.this,"You taped!",Toast.LENGTH_SHORT).show();
try {
startActivity(new Intent(MainActivity.this, FuelChoiceActivity.class));
}catch (Exception e){
System.out.println(e);
}
}
Here is my code. I've added the new activity to my manifest.xml. The try/catch block is not returning any exeption. When i press the button the toast is executed and displayed but the page is not changing. This onClickListener is inside an adapter method 'getView'so it can be obtained by any button generated from the adapter. I tried putting other events and they work! The only thing that doesn't is going to the new Activity.
here is my log when i debug and click on a button:

Thanks for reading and your time. I would appreciate thoughts.

My main activity extends Activity
public class MainActivity extends Activity
In this activity i was trying to to move to another that it was extending AppCombatActivity class.
public class FuelChoiceActivity extends AppCombatActivity
so the syntax and all is right. So i changed the FuelChoiceActivity(the activity i desired to move at) extend to :
public class FuelChoiceActivity extends Activity
Seems like you cannot move to another activity if they both dont extend the same class.

Any solutions to this error?

I have an android application that would use an SQLite database. But when it gets to the select statement it force closes. I have a class file that I use for doing this :

}
}
I think it is on the getID() clause but I can't see anything wrong with it nor my SELECT statetment. What I am trying to do here is to get the value of the saved_ip_address which is at the very bottom of the ipaddress table.
Here is my LogCat where the start of error is bolded out.
Thank You
