the java code

package com.dvp.android.gallery;  import android.os.bundle; import android.support.v4.app.fragmentactivity;  import com.google.android.gms.maps.supportmapfragment;   public class gps extends fragmentactivity{     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.gps);        supportmapfragment fragment = new supportmapfragment();        fragment.getfragmentmanager().begintransaction().add(android.r.id.content, fragment).commit();      }   } 

and xml :

<?xml version="1.0" encoding="utf-8"?> <fragment xmlns:android="http://schemas.android.com/apk/res/android"           android:id="@+id/map"           android:layout_width="fill_parent"           android:layout_height="fill_parent"           class="com.google.android.gms.maps.supportmapfragment" /> 

i googled , found no information exception. i'm confused problem , don't know how fix it. have idea how fix it? thanks.

there kind of mismatch between package specified in manifest file , package have provided activities in it.

try change:

 <activity         android:name="in.wptrafficanalyzer.locationgooglemapv2demo.mainactivity"         android:label="@string/app_name" >         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity> 

to:

 <activity         android:name=".mainactivity"         android:label="@string/app_name" >         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity> 

and don't write package cased latters , not, change permissions package it's written in package section:

 <permission       android:name="in.wptrafficanalyzer.locationgooglemapv2demo.permission.maps_receive"       android:protectionlevel="signature"/>  <uses-permission android:name="in.wptrafficanalyzer.locationgooglemapv2demo.permission.maps_receive"/>
