Hello, I've just started to learn development for the android.

I set up a test app with a basic textview that when you clicked on it, changed text. that worked fine. So I decided I wanted to do something interesting with google maps using mapview.

I've followed the instructions in the documentation, and looked around at the demomaps demo app, but when I launch my app in a AVD (pointed to the correct source, google APIs lvl3) I get "the application has stopped unexpectedly. please try again", when I launch in debug mode, the only error I get is "source not found"

Here are some excerpts from my code:

views

<?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"
    >
    <com.google.android.maps.MapView
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"
        android:enabled="true"
        android:clickable="true"
        android:apiKey="[ommitted for safety - i have an apikey though]"
        />
</LinearLayout>

manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="leblanc.test.HelloCora"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">

        <activity android:name=".hello"
                  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-sdk android:minSdkVersion="3" />
    <uses-library android:name="com.google.android.maps" />
</manifest> 

my source .java is basically default

I am developing in eclipse using the ADT, on a linux machine

let me know if there is any other info you need

Thanks!

EDIT: More information on the error I am getting.

Also, the interesting thing is that the demomaps demo application in the android SDK does not crash (though the map data never loads, even though it has internet access permission)

+1  A: 

I think there is problem in "accessing map from web(google map)".

For accessing web, we have to add "INTERNET PERMISSION" in AndroidMenifest.xml file.

so add the following line below </application> tag.

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

I added that to my manifest file, but still got the same error. The weird thing is that the mapsdemo project provided in the android SDK does not crash.
