NumberFormatException For Input String "4018.B"

The following code comes from a Android App for Handheld Scanner Device; the Device should scan different Barcodes and QR codes, different digit ranges, numbers and digits;
that´s why I decided to go with .matcher instead of Regular Expressions; The following code works fine when it comes to parse combinations like "1367+700" etc.:
editBarcode.setOnClickListener(new View.OnClickListener() { //tv is the TextView.
public void onClick(View v) {
code = editBarcode.getText().toString();
XXXStorageApp.getInstance().setScannedCode(code);
editBarcode.setText("");
if (ScanService.checkEnteredCode(code, basic, content, MainDetailActivity.this) == true) {
return;
}
else {
Pattern p = Pattern.compile(code);
Matcher matcher = p.matcher(Pattern.quote("\\+"));
if (matcher.find()){
retrievedItemNo = String.valueOf(matcher);
}
String intermediateItemNo = code;
String[] splitString = intermediateItemNo.split(Pattern.quote("+"));
retrievedItemNo = splitString [0];
String intermediateString = code.substring(code.indexOf("+") + 1);
retrievedQuantity = intermediateString.split("\\+")[0];
if(XXXStorageApp.getInstance().NoList.contains(retrievedItemNo) || XXXStorageApp.getInstance().EanList.contains(scannedCode)){
Log.d(String.valueOf(XXXStorageApp.getInstance().NoList),"NoList");
Log.d(String.valueOf(XXXStorageApp.getInstance().EanList),"EanList");
}
else {
Log.d(String.valueOf(XXXStorageApp.getInstance().NoList),"NoList");
Log.d(String.valueOf(XXXStorageApp.getInstance().EanList),"EanList");

}}
however the App crashes with a
java.lang.NumberFormatException: For input string: "4018.B"
So, the problem here is to parse a string like "4018.B+95".
I don´t know how to handle this mixed input String with .matcher and definitely don´t want to use a Regular Expression; so basically, all of the following Input Strings - including Type conversion - should be handled correctly:
1256+70
1235.B+70
1256+70+DB
1235.B+70+DB
1256+70+DB2020-123
1235.B+70+DB2020-123
1256+0+DB2020-123
1235.B+0+DB2020-123
So, basically I need a condition for .matcher() that handles input like
"1235.B"
a mixed Integer and String; I need to store it in one variable which is of type String;
the problem here is that the "." in "1235.B" is not recognized and the App crashes hence, because the Number contains a string (".B")
So, two questions here:
How can I use .matcher() to recognize if a String contains ".B" or ".C" or anything similar?
How do I handle the different Types correctly in one Variable type?
As I am stuck with this, I would appreciate any hints or help.

Integer putExtra() in Intent Data is being set as ParcelledData causing AsyncTask exception?

I am running into an error when attempting to getExtras() from an intent. At the moment the Intent Data says its a ParcelledData piece but the argument I entered in the putExtra() method was actually of type int. This causes an exception when during the doIntBackground() process.
Application Context
Flow.java is a container for items called flowElements (aka. Tasks).
A Flow object has a LinkedList which keeps track of all its flowElements.
SandBoxMain.java is an activity where the user can see all the current flowElements in the Flow they are currently working on, or create a flowElement one.
ElementDesigner.java is an activity where the user can name and time their new flowElement.

edit; please note I removed the OnCreate Methods, for the sake post length!

Invalid int: "Bundle[mParcelledData.dataSize=24]"
is the returned value of Bundle.toString(); which is, indeed, not a valid int. It means that in your code, you have
Integer.parseInt(bundle.toString());
E.g. could be the returned value of getIntent().getExtras();
Integer.parseInt(getIntent().getExtras().toString());
You can think of the Bundle as a key-value map. So if you are adding a value using one of its put (putInt) method, you have to use one of its get (getInt) method to retrieve it

LibGDX/Google Play Services Error

I have been trying to implement Google Play Services into my LibGDX game, and have been using the real-time Multiplayer APK.
However, after everyone has joined the room through auto-matching, I try to start the game through calling a method to change the screen, but i get the error as followed. Even if i removed the contents of the method, the same error still occurs. Could anyone enlighten me?
Thank you!

This is where i initiate the class

}
};
_gameHelper.setup(gameHelperListerner);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();config.useImmersiveMode = true;
initialize(new MacroHardv2(this), config);
}
And The class constructor is as follows
public MacroHardv2(ActionResolver actionResolver) {
this.actionResolver = actionResolver;
actionResolver.setGame(this);
}

You are trying to call
this.game.multiplayerGameReady();
But you probably didn't set "this.game" anywhere. Where did you define your "game" object. Can you please show the code block that you define it and also set it, or instantiate it.
So "this.game" is your null object you trying to use.

You need to initialize with values.
Double deslatituded, deslongituded, srclatituded, srclongituded;
You declare the doubles, but these are objects, not primitives. Therefore the default value is null. And the unboxing tries to get the primitive like
null.doubleValue()
Make them primitive or assign a default value like:
Double desLatituded = new Double(0);

I am not sure what is your error. But one of the scenario is
you declare class variables
private final LatLng end = new LatLng(deslatituded, deslongituded);
private final LatLng start = new LatLng(srclatituded, srclongituded);
Here deslatituded, deslongituded values must be null. Maybe this will the reason for the nullPoiner please check this.
You need to pass the values for this. Or just initialise the values like deslatituded=0 or something. This will save you from crash

Try this (and make sure your LatLng variables aren't final):
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps_activity_connect);
pref = getSharedPreferences("gps", Context.MODE_PRIVATE);
Bundle extras = getIntent().getExtras();
if (extras != null) {
deslatituded = extras.getDouble("deslatitude");
deslongituded = extras.getDouble("deslongitude");
srclatituded = extras.getDouble("srclatitude");
srclongituded = extras.getDouble("srclongitude");
// NEW CODE
end = new LatLng(deslatituded, deslongituded);
start = new LatLng(srclatituded, srclongituded);
// END NEW CODE
vechile = extras.getString("vechile");
if (!Utils.isConnected(getApplicationContext())) {
Toast.makeText(getApplicationContext(), "Internet not available. Cross check your internet connectivity and try again", Toast.LENGTH_LONG).show();
return;
}
if (!Utils.isGPSTurnOn(getApplicationContext())) {
showGPSDialog();
return;
}
}
}

Please check if your extras has the key "deslatitude"
like:
if(getIntent().hasCategory("deslatitude"))
{
deslatituded = extras.getDouble("deslatitude");
}
Log.e(TAG, "deslatitude: " + deslatituded );
And if your log prints the valuew then check it for all (deslat,deslong,srclat,srclong)

Are there any values in
extras.getDouble("deslatitude");
extras.getDouble("deslongitude");
extras.getDouble("srclatitude");
extras.getDouble("srclongitude");
there is nothing in intent extras.

How to pass data in a class to another member?

I have this code and I am trying to pass this.thecost to the public void click() method but it looks like it is not working because I receive "Paymnet Failed" when click the paypal button.
What did i go wrong?
by the way, what do you call the private {}, private void {} - all those function() looking thing?
private void initUI(int theprice) {
launchPayPalButton = mPayPal.getCheckoutButton(this,
PayPal.BUTTON_278x43, CheckoutButton.TEXT_PAY);
LinearLayout.LayoutParams params = new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
params.bottomMargin = theprice;
this.thecost = theprice;
launchPayPalButton.setLayoutParams(params);
launchPayPalButton.setOnClickListener(this);
((LinearLayout)findViewById(R.id.main_layout2)).addView(launchPayPalButton);
}
public void onClick(View v) {
payWithPaypal(this.thecost);
}
private void payWithPaypal(Integer gg) {
PayPalPayment newPayment = new PayPalPayment();
BigDecimal bigDecimal=new BigDecimal(gg);
newPayment.setSubtotal(bigDecimal);
newPayment.setCurrencyType(Currency.getInstance(Locale.US));
newPayment.setRecipient("email#hotmail.com");
newPayment.setMerchantName("My Merchant");
Intent paypalIntent = PayPal.getInstance().checkout(newPayment, this);
this.startActivityForResult(paypalIntent, 1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch(resultCode) {
case Activity.RESULT_OK:
String payKey = data.getStringExtra(PayPalActivity.EXTRA_PAY_KEY);
data.getStringExtra(PayPalActivity.EXTRA_PAY_KEY);
Toast.makeText(this,"Paymnet Successful",Toast.LENGTH_LONG).show();
break;
case Activity.RESULT_CANCELED:
Toast.makeText(this,"Paymnet Cancel",Toast.LENGTH_LONG).show();
break;
case PayPalActivity.RESULT_FAILURE:
Toast.makeText(this,"Paymnet Failed",Toast.LENGTH_LONG).show();
String errorID =
data.getStringExtra(PayPalActivity.EXTRA_ERROR_ID);
String errorMessage =
data.getStringExtra(PayPalActivity.EXTRA_ERROR_MESSAGE);
break;
}
EDITED: I call initUI() at the oncreate method
EDITED AGAIN: I change the global variable to 'double' because the price usually have decimal place.
Now i tried to toast the value and i see the error much clearer. The toast display a message that the value that was passed is "0.0". And because of that, there is an error of 'Payment Failed' and invalid payment.
int eprice;
double thecost;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.detail);
//Data mSource = new Data;
Intent myLocalIntent = getIntent();
Bundle myBundle = myLocalIntent.getExtras();
eprice = myBundle.getInt("eprice");
String epricetxt = myBundle.getString("eprice");
Adapter mAdapter = new Adapter(this, mSource);
//details = (Data) mAdapter.getItem(pos);
TextView theprice = (TextView) findViewById(R.id.priceTxt);
theprice.setText("Price: $" + epricetxt);
this.setCost(eprice);
this.thecost = eprice;
//Paypal
mPayPal=PayPal.initWithAppID(this,Constants.PAYPAL_APP_ID,PayPal.ENV_SANDBOX);
initUI(eprice);
}
private void initUI(int theprice) {
launchPayPalButton = mPayPal.getCheckoutButton(this,
PayPal.BUTTON_278x43, CheckoutButton.TEXT_PAY);
LinearLayout.LayoutParams params = new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
params.bottomMargin = theprice;
this.thecost = theprice;
launchPayPalButton.setLayoutParams(params);
launchPayPalButton.setOnClickListener(this);
((LinearLayout)findViewById(R.id.main_layout2)).addView(launchPayPalButton);
}
public void onClick(View v) {
//
payWithPaypal(getCost());
}
public void setCost(int cost) {
this.thecost = cost;
}
public double getCost() {
return this.thecost;
}
private void payWithPaypal(Double gg) {
PayPalPayment newPayment = new PayPalPayment();
Toast.makeText(getApplicationContext(),gg.toString(), Toast.LENGTH_LONG).show();
BigDecimal bigDecimal=new BigDecimal(gg);
newPayment.setSubtotal(bigDecimal);
newPayment.setCurrencyType(Currency.getInstance(Locale.US));
newPayment.setRecipient("email#hotmail.com");
newPayment.setMerchantName("My Merchant");
Intent paypalIntent = PayPal.getInstance().checkout(newPayment, this);
this.startActivityForResult(paypalIntent, 1);
}

We don't have enough information to tell you what went wrong here. For some reason, the PayPal API returned a failure status code. Maybe you don't have an internet connection?
Check the value of the error message string that you retrieved in this line:
String errorMessage = data.getStringExtra(PayPalActivity.EXTRA_ERROR_MESSAGE);
You can use the debugger to inspect it, or use the Log.e function in the Logger class to log it to Logcat so you can read it.
As for your second question:
by the way, what do you call the private {}, private void {} - all those function() looking thing?
In Java, those "function looking things" are called Methods.
EDIT: Okay, now that you've showed us your onCreate method, I can see where you are getting the value that you eventually pass to onInit here:
eprice = myBundle.getInt("eprice");
Doing this implies that you saved the value previously in the bundle in onSaveInstanceState(Bundle)
Did you do that? How does it get the value when you are starting the Activity for the first time?

Using my most updated code, I have no idea why my eprice doesn't work. But I have alternative solution. All i need to do is change
initUI(eprice);
initUI(Double.valueOf(epricetxt));
