Question

I’m using IntelliJ IDEA 9 (9.0.1) to create a simple map application (or at least trying to).
I’m using Android 2.0 with Google API’s 2.0.

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.example">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".MyActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <activity android:name=".disaster"/>
        <activity android:name=".map" android:label="@string/app_name"  android:theme="@android:style/Theme.NoTitleBar"/>
        <uses-library android:name="com.google.android.maps" />
    </application>
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
</manifest>

Class:

public class map extends MapActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);

        Button saveMe = (Button) findViewById(R.id.backBtn);
        saveMe.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                Intent myIntent = new Intent(view.getContext(), MyActivity.class);
                startActivityForResult(myIntent, 0);
            }
        });

    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;  //To change body of implemented methods use File | Settings | File Templates.
    }
}

View:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/wall"
    >
        <View android:id="@+id/mv"
       class="com.google.android.maps.MapView"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent"
       android:enabled="true"
       android:apiKey="08zxVQUd22SOeAuv8AEMS5hBAeOdll4OzDrNYpQ"/>

       <Button android:id="@+id/backBtn"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:text="@string/backBtn"/>

</LinearLayout>

This just gives me an empty screen.

What I’m doing wrong?

Edit: clarified my OP.

Answer 1

Make sure you have permissions to go to the internet and to access locations in your AndroidManifest.xml:

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

Edit:

Ok it seems the case is sensitive so changing from:

<View android:id="@+id/mv"

to

<view android:id="@+id/mv"

should display your map.
