Gradle: 

implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'

JSON cannot running in android 9 (Pie)

tambahkan ini di bagian android manifast, di dalam

<application

        android:allowBackup="true"

        android:icon="@mipmap/ic_launcher"

        android:label="@string/app_name"

        android:supportsRtl="true"

        android:theme="@style/AppTheme"

<!--tambah kan yang ini-->

        android:usesCleartextTraffic="true"

> 

oke langkah kedua yaitu tambahan uses-permission library org.apache.http.legacy  di dalam <application>   

<uses-library android:name="org.apache.http.legacy" android:required="false" />

Run ulang aplikasi dan di coba, selamat mencoba :)

Bulid Gradle 28.0.0

Android Code Radio Button

Android Image Slider

1. Copy di bagian gradel

dependencies { implementation "com.android.support:support-v4:28.0.0" implementation 'com.squareup.picasso:picasso:2.3.2' implementation 'com.nineoldandroids:library:2.4.0' implementation 'com.daimajia.slider:library:1.1.5@aar' }

2. Di bagian AndroidnManifast gunakan Permission

<uses-permission android:name="android.permission.INTERNET" />  
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

3. bagian layout create slider.xml

<?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:id="@+id/slider" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.heru.imageslider.Slider">
<com.daimajia.slider.library.SliderLayout android:id="@+id/slider" android:layout_width="match_parent" android:layout_height="200dp" /> </RelativeLayout>

4. Variabel public
private SliderLayout sliderLayout;

5. Slider.java

sliderLayout = (SliderLayout) findViewById(R.id.slider); // Load image dari URL HashMap<String,String> f_url= new HashMap<String, String>(); f_url.put("Gambar1", "http://thegorbalsla.com/wp-content/uploads/2018/08/Bukit-Doa-Tomohon-Manado-700x472.jpg"); f_url.put("Gambar2", "http://thegorbalsla.com/wp-content/uploads/2018/08/Bukit-Doa-Tomohon-Manado-700x472.jpg"); f_url.put("Gambar3, "http://thegorbalsla.com/wp-content/uploads/2018/08/Bukit-Doa-Tomohon-Manado-700x472.jpg"); f_url.put("Gambar4", "http://thegorbalsla.com/wp-content/uploads/2018/08/Bukit-Doa-Tomohon-Manado-700x472.jpg");

Intent Google Maps Application

Intent Google Maps Aplication
Pada saat intet 

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 

Uri.parse("http://maps.google.com/maps?saddr="+latPosisi+","+lonPosisi+"&daddr="+latTujuan+","+lonTujuan));
startActivity(intent);

Android Code Send Email

Set on clik Button to send Email

Button btnKirim = (Button) findViewById(R.id.btn_kirim);

btnKirim.setOnClickListener(new View.OnClickListener() {
    @Override    public void onClick(View v) {

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"herukzw@gmail.com"});
intent.putExtra(Intent.EXTRA_CC, new String[] {"google@gmail.com"});
intent.putExtra(Intent.EXTRA_SUBJECT, "E-mail dari Aplikasi Android");
intent.putExtra(Intent.EXTRA_TEXT, "hii coba tes kirim email ke sana");

 try {
    startActivity(Intent.createChooser(intent, "Apakah Ingin Mengirim E-mail ?"));
 } catch (android.content.ActivityNotFoundException ex) {
    //do anythings }

}});

//==========================

Keterangan :

1.Membuat variabel dan class intent menggunakan perintah : Intent intent = new Intent(Intent.ACTION_SEND);
2.Menyeting isi e-mail ke teks biasa : intent.setType("text/plain");
3.Menentukan alamat email : intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"herukzw@gmail.com"});
4.Menentukan CC :  intent.putExtra(Intent.EXTRA_CC, new String[] {"google@gmail.com"});
5.Menentukan subjek email : intent.putExtra(Intent.EXTRA_SUBJECT, "Email dari Aplikasi Android");

Auto Permission External Storage, Camera , Ect

Public Variabel

private static final int MY_PERMISSION_REQUEST = 1;

 --android Manifast---

 
jika ingin menggunakan permisi CAMERA , tinggal di rubah saja bagian WRITE_EXTERNAL_STORAGE.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.CAMERA" />
