How to integrate Stripe Payment in Android Java?

I need a Stripe Implementation for my Java Android App, but with a Server in Java, I don't know how to use node or php to implement that server-side and I found something on their docs:
https://stripe.com/docs/payments/accept-a-payment?integration=elements#android-create-payment-intent
but, the server-side is poorly explained.
All I've wrote until now is :
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="30dp"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".Checkout">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/logo"
android:layout_gravity="center"
/>
<TextView
android:id="#+id/youhavetopay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="22sp"
android:textColor="#color/colorPrimary"
android:fontFamily="#font/muli_black"
android:layout_gravity="center"
/>
<com.stripe.android.view.CardInputWidget
android:id="#+id/cardInputWidget"
android:layout_marginTop="30dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/payButton"
android:layout_gravity="center"
android:layout_marginTop="20dp"
/>
</LinearLayout>
</ScrollView>
and this
public class Checkout extends AppCompatActivity {
Button payBtn;
String message;
String price;
TextView text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_checkout);
payBtn = findViewById(R.id.payButton);
text = findViewById(R.id.youhavetopay);
Bundle extras = getIntent().getExtras();
if(extras != null) {
message = extras.getString("message");
price = extras.getString("passprice");
}
String t = "Pay $"+price;
payBtn.setText(t);
text.setText(message);
}
}
I have these implementations :
implementation "com.stripe:stripe-java:15.1.0"
implementation 'com.stripe:stripe-android:15.1.0'
implementation 'com.squareup.okhttp3:okhttp:4.4.0'
implementation 'com.google.code.gson:gson:2.8.6'
I really don't understand what I have to do from their docs. I only want a pay button that makes a payment from that card and if its accepted, do something on the database. A simple payment.
If you can guide me please, I would appreciate it! Any tutorials or advices are welcomed. I've tried to copy from the GitHub, but I saw many red lines from imports and I got lost.
Thank you in advance!

This sample includes both example Android client and a Java server implementations. You should be able to clone the repository and follow the appropriate READMEs to run those examples and see how this works. Follow along with the guide and if you have more specific questions please raise those.
You will need to be able to install and build android & java to run this, of course.

Which attribute replace for “layout_constraintGuide_Percent” at Android-Studio

I used constraint layout Android Studio 2.3.1 with constraint-layout:1.0.0-alpha4 dependency before, but now I am using 'com.android.support.constraint:constraint-layout:1.0.2', layout_constraintGuide_Percent attribute is not exists.
Which attribute replace for layout_constraintGuide_Percent?
my code:
<android.support.constraint.Guideline
android:id="#+id/guideline_vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_Percent="0.8"
tools:layout_editor_absoluteX="50dp"
tools:layout_editor_absoluteY="0dp" />

Replace the attribute with this
app:layout_constraintGuide_percent

Fix the errors in XML so the resource compiler can generate R.java for you.

Remove Import android.R; from imports in your activity class

In order to accesst "R.layout.edit_reminder" xml file you must import your "R" file which is found under the "gen" folder. This file is automatically generated, so you can go ahead and delete it and it will be generated again. Now, if you have any xml errores whatsoever the R file won't be generated, that's a sign that you have to look to your xml to find the problem.
In regards to the import, you'll find them on your Activity Class, at the very top right after the package declaration.
Make sure that the R you are importing is:
yourpackage.R;
rather tahn
android.R;
When writing code quickly at times android.R gets imported and you don't even notice. That's the first thing I always check, it's happened to me a couple of times already.
Next thing I would suggest doing is looking to see your console and problems view (if these are not set in your perspective, then go to Window>Show View>Other and select the appropriate ones).
Look for something along the lines of Error with xml file aborting build. Look for what xml file it is talking about, and then look for errors in it.
