4. Layout Creation

Create an interface with the following components and layouts:

RelativeLayout
TextView
RadioButton
RadioGroup

Open activity_main.xml then type the following codes:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/activity_main"
android:padding="15dp">
<TextView
android:text="Club sepak bola yang memenangkan liga champions adalah :"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textView"
android:textSize="25sp"
android:textColor="@android:color/black"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:textStyle="bold"/>
<RadioGroup
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/textView"
android:layout_centerHorizontal="true"
android:layout_marginTop="39dp"
android:id="@+id/radioGroup" >
<RadioButton
android:text="Real Madrid"
android:foreground="?attr/selectableItemBackground"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/radioButton"
android:onClick="onRadioButton"
android:layout_toLeftOf="@+id/radioGroup"
android:layout_toStartOf="@+id/radioGroup"
android:layout_below="@+id/radioGroup"/>
<RadioButton
android:text="Liverpool"
android:foreground="?attr/selectableItemBackground"
android:onClick="onRadioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/radioButton"
android:layout_alignLeft="@+id/radioButton"
android:layout_alignStart="@+id/radioButton"
android:layout_marginTop="36dp"
android:id="@+id/radioButton2"/>
<RadioButton
android:text="Barcelona"
android:foreground="?attr/selectableItemBackground"
android:onClick="onRadioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="26dp"
android:id="@+id/radioButton3"
android:layout_below="@+id/radioButton2"
android:layout_alignLeft="@+id/radioButton2"
android:layout_alignStart="@+id/radioButton2"/>
<RadioButton
android:text="Juventus"
android:foreground="?attr/selectableItemBackground"
android:onClick="onRadioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/radioButton3"
android:layout_alignLeft="@+id/radioButton3"
android:layout_alignStart="@+id/radioButton3"
android:layout_marginTop="39dp"
android:id="@+id/radioButton4"/>
</RadioGroup>
</RelativeLayout>

Make sure you enter the programming code correctly then a layout will be formed as shown below:

5. Java Coding

Next step is give commands to the components that have been formed in activity_main.xml. Open MainActivity.java then enter the code below:

package badoystudio.com.kuissederana;

import android.content.DialogInterface;
import android.os.Bundle;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

AlertDialog.Builder builder;
RadioGroup radiogroup;
//deklarasi var or obj

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

//radiogroup inisialisasi
radiogroup = (RadioGroup) findViewById(R.id.radioGroup);

}

//Memilih RadioButton

public void onRadioButton(View view) {

Boolean checked = ((RadioButton) view).isChecked();

switch (view.getId()) {
case R.id.radioButton:
if (checked)
tampilDialog();
break;

case R.id.radioButton2:
if (checked)
jawabanSalah();
break;
case R.id.radioButton3:
if (checked)
jawabanSalah();
break;
case R.id.radioButton4:
if (checked)
jawabanSalah();
break;
}

}

//menampilkan dialog
public void tampilDialog() {

builder = new AlertDialog.Builder(this);
builder.setCancelable(false);
builder.setTitle("Selamat !!!");
builder.setMessage("Jawaban kamu benar : Real Marid");
builder.setPositiveButton("OKE",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Toast.makeText(MainActivity.this, "Selamat", Toast.LENGTH_SHORT).show();
}
});

builder.setNegativeButton("ULANGI", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
radiogroup.clearCheck();
}
});

builder.create().show();

}
//menampilkan toast text jawaban salah
public void jawabanSalah(){

Toast.makeText(this, "Jawaban kamu Salah", Toast.LENGTH_SHORT).show();
}
}

6. Running Applications

The last step, please run the application that has been made using:

Android studio default emulator (android virtual device) or directly to the android smartphone, the results are as follows:

Display if True

Display if False

Publish the app

Publishing is process that makes Android applications available to users. When you publish an Android app, you perform two main tasks:

1. Preparing an app for publish includes the following tasks:

Set up the app for publication. At the very least, you should delete the Call Log and the attribute android:debuggable from the manifest file. The details of the app version must also be mentioned. Additionally, you might need to adjust a few other settings to comply with Google Play specifications or to fit the app's distribution strategy. To set the build settings for the published version of your app when using a Gradle build file, utilize the release build type.
Create and sign the app's release version.To create and sign a release version of your software, use a Gradle build file of the build release type. See Android Studio Build and Run.
The app's beta version should be tested. You should thoroughly test the release version of your software on at least one target tablet device and one target handset device before releasing it.
Publish updated app resources. All application resources, including multimedia and graphic assets, must be updated, added to the application, or configured on the appropriate production servers.
Install the servers and remote services that the application needs. Make sure external servers and services are secure and suitable for production if your app depends on them.

As part of the preparation phase, you might need to do a number of additional duties. For instance, in order to sign an application, you must obtain a private key. In order to safeguard your employees, business, and intellectual property, you may also need to set up an End User License Agreement (EULA). You must also generate icons for applications. You'll have a signed.apk file that you may give to users once you've finished releasing your app.

2. Publish/Upload the app to consumers

There are various ways to release Android applications. The most common way to publish apps is through app stores like Google Play, but you may also publish apps on your own website or by sending them directly to users.

Publish via the app store. We advise publishing your software through an app store like Google Play if you want to reach as many customers as you can with it. If you want to make your Android app available to many users worldwide, Google Play is a high-end app store that is quite helpful. However, you are free to use as many app marketplaces as you choose to distribute your program. Here is the link to Google Play.

With the help of Google Play, you can create, market, and distribute Android apps to users all over the world. When you publish your app on Google Play, you have access to a variety of developer tools that enable you to track sales, spot industry trends, and decide who your app is intended for. Additionally, you have access to several services that can generate cash, such billing through Google Play and software licensing. Google Play is the leading store for buying and selling Android apps thanks to its extensive selection of tools and features and its rich end-user community features.

The process and preparation you have to do to upload on Google Play :

Create marketing materials/promotional materials. You must produce marketing assets for your app, like as screenshots, videos, graphics, and promotional text, in order to take full advantage of Google Play's marketing and publicity possibilities.

Configure options and upload files. You can advertise your app on Google Play to a global user and device base. You can select the nations you want to target, the listing language you want to employ, and the rates you want to charge in each nation by customizing various Google Play options. Additionally, you can customize listing information like the category, rating, and app content type. You can upload promotional materials and applications as draft (unpublished) apps once you've finished selecting the options.

Publish the app's release version. When you are certain that your publish settings are set up correctly and your uploaded app is prepared to be made available to the public, you can click Publish in the Play Console and your app will be live and available for download around the globe in a matter of minutes.

Publish on Platform Site-wide. You can make your app downloadable on your own website or server, even on personal or business servers, if you don't want to release it on a store like Google Play. To do this, you must first get your app ready for release as you normally would. You simply need to host the APK file that is prepared for distribution on your website and then give your consumers the download link. The file will be downloaded and installed automatically by the Android operating system when the user accesses the download link from an Android device. The user must have Settings set to enable installation of apps from unknown sources in order for the installation process to begin automatically. Although releasing an app on your own website is rather simple, it might not be effective. For instance, you must handle and keep track of every financial transaction if you wish to monetise your software.
