MapView and MapActivity

Using the Google Maps library, you can create your own map-viewing Activity.

MapView and MapActivity

By default the Android SDK includes the Google APIs add-on, which in turn includes the Maps external library. The Google APIs add-on requires Android 1.5 SDK or later release.

Create a Android project with build target called "Google APIs".

Modify AndroidManifest.xml to include uses-library "com.google.android.maps", and grant permission of "android.permission.INTERNET".
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.AndroidMapView"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="4" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
<uses-library android:name="com.google.android.maps" />
<activity android:name=".AndroidMapViewActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>


To embed a MapView in your app, you have to obtain a Maps API key, refer to this post.

Modify main.xml to add com.google.android.maps.MapView, with your own Maps API Key.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<com.google.android.maps.MapView
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey="Your Maps API key here" />
</LinearLayout>


Main activity, extends MapActivity.
package com.AndroidMapView;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;

import android.os.Bundle;

public class AndroidMapViewActivity extends MapActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
}

@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
