MapView in android application

问题

I am trying include google map in my android application.

I gone through this procedure to get the Map API key.

After getting the key i wrote the following code to display the map in my application.

My Manifest file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mymap"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="17" />

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

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <uses-library android:name="com.google.android.maps" />

    <activity
        android:name="com.example.mymap.LocationActivity"
        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>

Layout <com.google.android.maps.MapView android:id="@+id/mapView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:apiKey="mykey" android:clickable="true" android:enabled="true" />

When i run the application i am getting an exception like this.

03-28 14:31:14.868: W/System.err(21147): IOException processing: 26

Remember MapView is depreciated. Google maps V2 is supported. and you cant get a new map v1 api key.

visit here to lean more about maps v2

if you are already using v2 :

Try to add following data to your manifest:

    <uses-permission  android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />  
    <permission
    android:name="com.example.mapdemo.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

<uses-permission android:name="com.ikolmobile.magicmap.permission.MAPS_RECEIVE" />
    <!-- My Location -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <!-- Maps API needs OpenGL ES 2.0. -->
    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />


<meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="YOUR KEY HERE" />

This is a known error when you have a problem with your API key:

take a look at the following posts:

android, google map errors: BaseTileRequest, Server returned: 3

Google map signed api key errors in Android

UPDATE:

from the link you posted for getting the Key you are getting a key for Google Map API V2 and hence it wont work with Google Maps API V1.

To integrate Google Map API V2 you can follow this blog post I wrote on this topic:

Google Map API V2
