Answer 1

I made a mistake in my manifest file.

I was suppose to write

<uses-library android:name="com.google.android.maps" />

in the appilcation tag, what i did was, i wrote it in manifest tag.

So basically i was suppose to follow below structure.

<manifest>
<uses-permission/>
<application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <uses-library android:name="com.google.android.maps" />

                       .
                       .
                       .

Answer 2

Have you set a permision on your AndroidManifest file like this:

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

Answer 3

I think you are using any method that is not compatible with your device api version means you are using any method of higher API level in a device(or emulator ) having lower API level than that.

As I got the same kind of error when I used killBackgroundProcess() method(which is available in android 2.2 and higher) in my app and tried to run the app in android 1.6.

Hope you got the problem.
