Hello World Android Studio

Create a new Project in Android Studio

• File → New → New Project…
• Set these options through the wizard steps:

• Type a name for your application, your Company Domain and browse to the project location.
• Select the platforms and minimum SDK for your application (G3M requires API 15+)
• Select Empty Activity
• Name your activity and its layout

G3M Gradle settings

• Add G3M modules to your project. Open your settings.gradle file and add the lines starting with '+':

include ':app'

+include ':G3MSharedSDK'
+project(':G3MSharedSDK').projectDir = new File(settingsDir, '../relative/path/to/G3MSharedSDK')

+include ':G3MAndroidSDK'
+project(':G3MAndroidSDK').projectDir = new File(settingsDir, '../relative/path/to/G3MAndroidSDK')

Tip: Alternatively, you may reference the location of G3M modules absolutely by typing:

include ':G3MSharedSDK'
project(':G3MSharedSDK').projectDir = new File('/absolute/path/to/G3MSharedSDK')

Add some dependencies to your application module. Open your module’s build.gradle file and add:

dependencies {
   compile fileTree(dir: 'libs', include: ['*.jar'])
   testCompile 'junit:junit:4.12'
   compile 'com.android.support:appcompat-v7:23.1.1'
+   compile project(':G3MSharedSDK')
+   compile project(':G3MAndroidSDK')
}

Tip: After these changes you should sync your project as the IDE suggests.

Starting with the app

The Layout

G3M widget can be added to any ViewGroup, so let’s add a FrameLayout as a place holder. Open the activity layout file (activity_main.xml), remove the lines starting with ‘-’ and add the following ones:

<?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:paddingBottom="@dimen/activity_vertical_margin"
   android:paddingLeft="@dimen/activity_horizontal_margin"
   android:paddingRight="@dimen/activity_horizontal_margin"
   android:paddingTop="@dimen/activity_vertical_margin"
   tools:context="mlmateo.helloworldandroidstudio.MainActivity">

-   <TextView .../>

+   <FrameLayout
+       android:id="@+id/g3m_widget_holder"
+       android:layout_width="match_parent"
+       android:layout_height="match_parent" />

</RelativeLayout>

The Code

Add the bold lines to the onCreate method of your MainActivity:

public class MainActivity extends Activity {
  @Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

+    final G3MBuilder_Android builder = new G3MBuilder_Android(this);
+    G3MWidget_Android g3mWidget = builder.createWidget();
+    final FrameLayout layout = (FrameLayout) findViewById(R.id.g3m_widget_holder);
+    layout.addView(g3mWidget);
}
