<figure><img src="https://3873791589-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F7cujmJ5QHdJaAjH815aZ%2Fuploads%2FQIdnigZJe9Y9fj5sCuVo%2Fimage.png?alt=media&#x26;token=5da29fb9-6855-4fad-9d00-c0015b9883fe" alt=""><figcaption></figcaption></figure>

### **B.** Get the latest data from your device via Android

#### **1. AndroidManifest.xml**

In order to execute the Antares API, we need Internet access and in order to access the Internet on Android, we need to add the following lines to AndroidManifest.xml.

{% code lineNumbers="true" %}

```xml
<!--- IMPORTANT!!!!!!! --->
<!--- Tambahkan line berikut di AndroidManifest.xml Anda --->
<!--- Setelah manifest --->
<uses-permission android:name="android.permission.INTERNET" />
<!--- Sebelum application --->
```

{% endcode %}

#### **2. activity\_main.xml**

Modify **ALL** the contents of activity\_main.xml with the following content:

{% code lineNumbers="true" %}

```xml
<?xml version="1.0" encoding="utf-8"?>
<android.widget.LinearLayout 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"
    tools:context=".MainActivity"
    android:orientation="vertical">

    <TextView
        android:id="@+id/txtData"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="No Data"
        android:textSize="24sp"/>

    <Button
        android:id="@+id/btnRefresh"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Refresh"/>

    <Button
        android:id="@+id/btnOn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="On"/>


    <Button
        android:id="@+id/btnOff"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Off"/>

</android.widget.LinearLayout>
```

{% endcode %}

#### **3. MainActivity.java**

{% code lineNumbers="true" %}
