Google Maps Android API v2 application crash

Question

I'm trying to get the sample code of Android 'Google Maps Android API v2' working. I get the project built without errors. However, when I try to run the app on Everpad , the app crashes immediately.

The logcat output:

08-30 17:12:42.620: E/dalvikvm(4352): Could not find class 'com.dvp.android.gallery.GPS', referenced from method com.dvp.android.gallery.Acceuil$5.onClick

The Manifest :

        <activity

                />
        <activity

                android:label="Infos"/>
    </application>
    <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyA0HMTTGLqlYaq6jOuS0imbjt7GmUHyK0c"/>

    <uses-sdk android:minSdkVersion="4" />


    <uses-permission android:name="com.dvp.android.gallery.maps.permission.MAPS_RECEIVE" />
    <uses-permission android:name="android.permission.INTERNET" />

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

</manifest>

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 Finally the 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 and found no information about this exception. I'm really confused about this problem and don't know how to fix it. Does anyone have idea how to fix it? Thanks.

The google map sample is a bear to get going. Keep trying you'll get it. — danny117, Aug 29 '13 at 01:51

There is some kind of mismatch between the package you specified in your Manifest file and the package you have provided for the Activities in it.

try to 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 some package with cased latters and some not, change your permissions package to be as it's written in the package section:

 <permission
      android:name="in.wptrafficanalyzer.LocationGoogleMapV2Demo.permission.MAPS_RECEIVE"
      android:protectionLevel="signature"/>

<uses-permission android:name="in.wptrafficanalyzer.LocationGoogleMapV2Demo.permission.MAPS_RECEIVE"/>

well I don't see anything wrong with. Try to recreate the project. Maybe it will help you. — Emil Adz, Aug 30 '13 at 14:51

Try this:

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

        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

you can implement following:

<application
        android:allowBackup="true"
        android:icon="@drawable/icn_button2"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <uses-library android:name="com.google.android.maps" />

        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

        <activity
            android:name="com.gc.materialdesigndemo.ui.MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter>
                <action android:name="br.com.informapa.MESSAGE" />

                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
    </application>
