Google Awareness API 사용 예제입니다. 일단 앞서 포스팅한 Google API Key 등록을 먼저 해야 합니다. Google API Key를 획득했다면 다음과 같이 AndroidManifest.xml 에 해당 키 정보를 기입해줍니다.

AndroidManifest.xml

<application
  android:allowBackup="true"
  android:icon="@mipmap/ic_launcher"
  android:label="@string/app_name"
  android:supportsRtl="true"
  android:theme="@style/AppTheme">

  <meta-data
    android:name="com.google.android.awareness.API_KEY"
    android:value="API_KEY" />

  <activity android:name=".MainActivity">
    <intent-filter>
      <action android:name="android.intent.action.MAIN" />

      <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
  </activity>
</application>

Activity_main.xml

그리고 간단한 버튼 4개를 배치해서 테스트를 하기 위한 activity_main.xml 코드는 다음과 같습니다.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/activity_main"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:paddingTop="@dimen/activity_vertical_margin"
  android:paddingBottom="@dimen/activity_vertical_margin"
  android:paddingLeft="@dimen/activity_horizontal_margin"
  android:paddingRight="@dimen/activity_horizontal_margin"
  android:orientation="vertical">

  <Button
    android:id="@+id/btn_get_location"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Get Location" />

  <Button
    android:id="@+id/btn_get_activity"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Get Activity" />

  <Button
    android:id="@+id/btn_get_place"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Get Place" />

  <Button
    android:id="@+id/btn_get_weather"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Get Weather" />

  <ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
      android:id="@+id/textview"
      android:layout_width="match_parent"
      android:layout_height="match_parent" />

  </ScrollView>
</LinearLayout>

MainActivity.java

마지막으로, MainActivity.java 코드입니다.
