I'm trying to do a simple app with a map... I've follow this example and manage to do the app. Also need to add this to the manifiest:
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
The problem is I get a blank screen on my Motorola CilqXT but runs fine on a Galaxy Fame.
I'm guessing the problem maybe that my CliqXT doesn't support openGL 2.
So my question is how can I develop and app with just a map for my device?
Other applications as EasyTaxi, Netmonitor and a lot more, works fine on my phone, so I guess there must be something I can do.

EDIT
Sadly I've got to say that I think it's impossible to run google maps android api v2 on a device with no openGL ES2.0 support. And sadly, my Cliq XT doesn't support it.
Thank you all for helping me!!

Have you added this in your manifest:
<uses-feature android:glEsVersion="0x00020000"

I know there are a many questions on this topic. I have went to all of those questions and tried a lot of suggestions given in stack overflow and at other sites. But unfortunately, none has solved my problem.
When I am using MapView and MapsActivity, grid is displayed instead of maps. As suggested, I have regenerated API key and I have made sure that I have given the same package name as of my application, SHA1 key and I have enabled the Google Maps ApI for Android in the Credentials. I have given all the permissions, that are needed for maps, in Manifestfile.xml, my manifest file is as shown below:
<?xml version="1.0" encoding="utf-8"?>

My layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.google.android.gms.maps.MapView android:id="#+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
and my activity that extends MapActivity:
package com.example.mapsample;
import android.os.Bundle;
import com.google.android.maps.MapActivity;
public class GoogleMaps_Sample extends MapActivity{
public void onCreate(Bundle b){
super.onCreate(b);
setContentView(R.layout.googlemapssample);
}
#Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
When I use the above activity, grids are displayed. When I extends FragmentActivity instead of MapAcitivity and fragment instead of mapview, I have been getting an error saying unfortunately stopped and some times it says some fragment class error.
I have also installed Google API system image for the emulator I am using. I have downloaded Google Play Services too. But still, maps is not displayed to me. I have done almost everything as suggested in other questions.
What is the error or mistake in my application that is preventing maps to get displayed and that displays grid instead.
Thanks in advance.
What is possibly wrong with this code?
I'm not seeing what could possibly be intrefering and the API key is right but it continues to show a grey area.
Can someone give a touch on this?

Seriously, this maps thing is driving me mad.
Check these things
Correct API Key and
in manifest
Google maps should be on in your devloper console
INTERNET PERMISSION in manifest
Updated google play services
Ok, I found a solution, pretty stupid in my opinion but it worked.
I had to declare the api key in the layout.xml
After that, everything worked like charm
NB - I've been through this site with a fine toothed comb and can't find an answer that helps me. Though, this seems to be a common problem for whatever reason.
I'm a proper noob at Java, and I'm currently teaching myself. I'm working towards GeoFencing, but obviously need to learn about including Maps in my app first. I've tried so many things but I can't get a working Map to display, instead I get a blank outline of where a map should go and then some zoom buttons and a Google Logo. Can anyone point out what I'm doing wrong?
For the record:
I'm testing on Stock Galaxy S3 i9300 - 4.3
Included Google Play Services Library
Included android.support.v4.jar
Tried two different API keys
Tried multiple 'Project Build Targets' (both Android and Google ones_
I am however using the API key generated from degug.keystore. Would that cause a problem.
Thanks in advance :)

I followed two tutorials to create an android app that displays a google map. The activity launches but there is no map visible. The zoom buttons on the side are seen though. What do I do to see the map ?

The problem you describe usually happens when there is some problem with the way you defined Google Maps permissions (from a quick look at your manifest file the look OK) or from a bad configuration of the of the allowed API in the Google's API Console.
Take a look at this guide I wrote on how to configure Google Maps API V2 and make sure you do all the steps right:
Google Maps API V2
Make sure that you turn on the Google Maps V2 for Android in the console and not the one for web. another thing that looks strange in the manifest file you posted is your key (it looks too short - did you cut it in purpose) if you are not sure with the way you produced you key I would suggest you to go over this guide as well:
Google Maps API V2 key
try these steps. it worked for me.
change your main layout with this.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
</RelativeLayout>
change your Activity to fragment activity and follow this code
public class YourActivity extends FragmentActivity
//implements GoogleMap.InfoWindowAdapter
{
private GoogleMap googleMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
googleMap = mapFragment.getMap();
googleMap.setMyLocationEnabled(true);
}
}
check your project properties file google play library reference must be their
target=android-10
android.library.reference.1=../google-play-services_lib
if library reference not than import library project from
yoursdkPath\sdk\extras\google\google_play_services
after you had import this library . configure this library into your project
During my studies i must develop an application base on google maps, user should found QRcode on the map and scan them.
So i create an android application including ggogle play lib and including the sdk library. i suppose i have created the right api key in my account google console whith tha SHA1 of my computeur.

can every one can tel me why i have button on my map button i have a white screen all the time, with fragments or whithout, it's the same with a map view.
Maybe the while-loop is the problem? I don't see a change of i so this appears to be a infinite loop.
Try to get the reference to the GoogleMap in the onResume() method without a loop, like
GoogleMap map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
I think you got the this Image.
At the moment, referencing the Google Android Map Api v2 you can't run google maps v2 on Android emulator; you must use a device for your tests.
I'm not sure if you didn't update the "my api key" value with your api key on purpose.
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="my api key"/>
And I don't remember seeing this in the docs, maybe you should remove it:
<uses-library android:name="com.google.android.maps"/>
Also COARSE_LOCATION is misspelled:
<uses-permission android:name="android.permission.ACCESS_CORSE_LOCATION" />
And you declared this twice. hehe. =)
<uses-permission android:name="android.permission.INTERNET"/>
