I am newbie on Android Google Maps API and I was trying to develop a small app using the API. I use as a reference the Google documentation form: https://developers.google.com/maps/documentation/android/ and I follow all the step with caution. When I build it and install it on to my device (Android 2.3.6) the app crash. I follow all the instructions to sign the app and get the API key for this specific app, tried all the step of the documentation several times without any good results. Please, can someone help me with this? I there something missing?
Thank you!

First thing as you are having the API level 8 or below so you have to use the SupportMapFragment instead of MapFragment as below in your layout file.
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
Second thing you have to extend the FragmentActivity instead of Activity :
public class MainActivity extends FragmentActivity {
Do the above changes and then run your application.

I just created a simple hello world program, all codes are fine it seems, but something makes the android to show "unfortunately app needs to close" error
the startingPoint.java code which is the launcher class

So I post my comment as an answer :)
It seems that android try to find the class in your package com.example.demo4.startingPoint, but in your code the package is just demo4. Try to change the first line by package com.example.demo4.
Resloved...it was as indicated by Mtoypc. the package name was different and it was not reflected in the startingPoint.java
I'm new in Android development. I want to add Google maps to my application. I have done lots of searches but still the same problem arises when I run the application "Unfortunately , application has stopped"
So this is my java class
package com.example.hellomap;
import com.google.android.maps.MapView;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_main);
MapView map =(MapView) findViewById(R.id.map);
}
}
the xml file :
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>
and the Manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.hellomap"
android:versionCode="1"

Thanks for help :)
EXCEPTION :- ClassNotFoundException
please check GooglePlayService Library Project First.
Second Thing You Can Not Type Cast Fragment To Map View, please read this
Update:-
Follow The Step:-
1)Create New Project
2)Import GooglePlayService Library project into Your Workspace.
3)assign Google play Service library project as library project to your project
4)now add Map Fragment/Supported Map Fragment into your activity layout file
5)make sure this class found
how to check==>press control Key from keyboard and click on class name id you found class then it's okay other wise fix it first.
i prefer to use Supported Fragment.
6)define all permission as describe in link i posted previously.
6)now its time to generate api key for map ,follow the step from given link.
Thanks i hope its help

well by simply reading the logcat i found this: requires android.permission.WRITE_SETTINGS at the end of the 4th line.
am getting this exception:

it says that class is not there, but it IS there. I tried to configure things in my project's build path, but not too sure what to tweak there.
And here is how I start my Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="business.premium"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="15"/>
<uses-permission android:name="android.permission.INTERNET" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/CustomTheme"
android:name="MyApplication"
android:debuggable="true">
<activity
android:name=".Problemio"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Any thoughts on how to solve this, or what to look into? Thanks!
Its because you specified the "android:name" attribute in the application node in the manifest file.
Do not use the android:name attribute!
It, misleadingly, does not have anything to do with the name of your app and is actually the name of an extra class to load before loading your application. That's why you are getting the ClassNotFoundException.
Remove it and it should work:
<application
android:icon="#drawable/icon"
android:label="#string/app_name"
android:description="#string/help_text" >
This answer is taken from: java.lang.ClassNotFoundException on working app
I'm trying to use OSMdroid for a project, and i'm utterly unable to make the simplest code work.
Well, a few days ago i was able to display maps and so on, and now i can't even instantiate a MapView.
I reduced the code to its sipmlest form.
I work with eclipse. I downloaded osmdroid-android-3.0.5.jar and slf4j-android-1.5.8.jar, and i included them in the project by adding lines to the classpath file
<classpathentry kind="lib" path="lib/osmdroid-android-3.0.5.jar"/>
<classpathentry kind="lib" path="lib/slf4j-android-1.5.8.jar"/>
Or by right clicking on them then Build Path-> Add to build path (both gave the same result, anyway)
Then i typed this code:
import android.app.Activity;
import org.osmdroid.tileprovider.tilesource.TileSourceFactory;
import org.osmdroid.util.GeoPoint;
import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;
import android.os.Bundle;
public class TestMapActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MapView mv=new MapView(this,256);
}
}
And i get a bug when running it on the emulator:
04-17 09:10:31.181: E/AndroidRuntime(595): FATAL EXCEPTION: main

When i comment out the "MapView mv=new MapView(this,256);" it works, so i don't understand why the mapview can't be instantiated.
Any idea on this?
Thank you for your attention.

Change Folder name "lib" to "libs" and put all jar files in that folder and Charge path of jar
files to "libs" folder. I am not sure but I think it will work.
Try to use the 3.0.7 and clean the project.
Let me know.
