I'm trying to display google map on my android app when user click on a button.
when I click the button the app stops.No error in the code.
I believe I've done everything right
1-I got the API KEY
2-I added the Google_Play_Services_lib.jar to the dependencies folder
3-added extra support tool
4-included the permissions,my key to the manifest
5-added fragment to my xml layout fie for the map
please help I feel like I've read and watched every tutorial there is...nothing worked!

have you tried to look at this SO post?
seems like changing the xml to match your class name fixes most issues.
Google Maps V2 - Error inflating class Fragment
If you are targeting api level 8 and above then you can't use a simple Activity, you need to extend FragmentActivity.
I'm guessing this is the reason you have the inflating problem.
And you are missing this meta-data section in you manifest file:
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
place it next to your's api key meta-data section.
I did use Google Maps v2 API for android in my recent app development and I cannot even start to tell you how long it took to just have the map show up on the screen. I eventually got it working and I have the project on Github which you can look through and make sure to read through all the important files like Manifest and res/ folder;

i'm trying to build a app with a Google Maps Api V2, but i only got a blank screen with zoom buttons everytime. I think everything is fine in my code. I have all the permissions necessary, i correctly got the Key. I already delete debug.keystore to eclipse generate another one, but i still got the same blank screen with zoom buttons. Can anyone see if i doing something wrong in my codes ?

I already read a lot of things here, but no one could help me.
Firstly: As your map is a fragment (MAPS API V.2) you should extend your MainActivity as a FragmentActivity
public class MainActivity extends FragmentActivity {
instead of
public class MainActivity extends Activity {
Secondly: When casting the fragment as a map use the SupportMapFragment class (for better cmpatability between android versions) and getSupportFragmentManager() to find your map fragment.
((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
instead of
((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
Also: as per the comments of the question "asker"(!?): If you find that your app is working in an Emulator but not on an actual device, ensure that you use your Debug.Keystore when building the App.
Note: Ensure at all times that you are using backwards compatible support libraries across your entire app (If you are targeting multiple versions of android of course but I can't understand why anyone would limit their app to only a couple of versions?) and also that all your keys, credentials, Auths etc.. are properly set up in the Google developers console. https://console.developers.google.com/
After do what Ryno Coetzee suggest me, the app work on emulator but not on device. But the app doesnt work on device because when i export to a apk file, i was using another keystore instead debug.keystore. After that, my app finally work on device and on emulator.
Thanks !
I'm new to the Android world, and I need to create an app using Google Maps Android API. I follow the instructions in:
https://developers.google.com/maps/documentation/android/start
and whenever I start the AVD I get an error:

Also tried the code that it's provided here:

being the MainActivity file code:
package com.example.map;
import com.google.android.gms.maps.*;
import com.google.android.gms.maps.model.*;
import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_activity);
// Get a handle to the Map Fragment
GoogleMap map = ((MapFragment) getFragmentManager()
.findFragmentById(R.id.map)).getMap();
LatLng sydney = new LatLng(-33.867, 151.206);
map.setMyLocationEnabled(true);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(sydney, 13));
map.addMarker(new MarkerOptions()
.title("Sydney")
.snippet("The most populous city in Australia.")
.position(sydney));
}
}
Any Ideas?
The first thing I would recommend is to not show your API key to the public; this are supposed to be private to whomever is developing the application.
Also the format of this meta tag is wrong:
<meta-data
android:name="com.google.android.maps.v2.AIzaSyB7AMKbYsVajgb6D0zpq9wUODX9gdR2DhE"
android:value="AIzaSyB7AMKbYsVajgb6D0zpq9wUODX9gdR2DhE"/>
You are copying your API key at the end of the name. I strongly suggest you create a new API key and do not use this one that you have exposed to the public. There might be other errors, but without the stack trace is hard to say.
See this page: http://developer.android.com/google/play-services/setup.html
Specifically:
To test your app when using the Google Play services SDK, you must use
either:
A compatible Android device that runs Android 2.3 or higher and includes Google Play Store.
The Android emulator with an AVD that runs the Google APIs platform based on Android 4.2.2 or higher.
So make sure the emulator you're using is Android 4.2.2 or greater. If it is below this level, Google Play Services is not available on the emulator, and you must use a physical android device to test it out.
If you have to test on a lower-end device emulator, there are workarounds to this but they aren't officially supported by Google so your mileage may vary.
See this link:

I added the google-play-services_lib appropriately. and also added the android-support-v4.jar is also in "Android private libraries".
Notice that the project build target is: Google APIs 4.2.2
and the android version in my Samsung phone is: 2.3.4
I've been trying last couple of days, I also tried in the emulator, same thing is happening.
Please help me to solve the issue.
Thanks.
I had a similar problem.. I have solved it. Android emulators aren't working. You should work your app on your phone. When exporting your project, your sha1 is changing. You must copy that sha1 and make a new API-KEY in google api console. (don't forget the change manifest file). After uploading your phone, it works..
EDIT :
I transferred my 20+ projects that tries to use Google Maps for Android v2. After changing keys and stuff, now, it works. I don't know what made this work, but thank you all. I got one keystore, the key is right. I guess it magically fixed somehow. Well, thanks guys.
I'm doing searches for 2 days and I couldn't fix this problem. I did everything, yet, this application can not work.
I want my application to work on Android 2.2 and above. Like it says "if you create your app in level 8, it'll support 95% of market".
Here are my screenshots and source codes:
I'm pasting the source code which is the easiest to get. I took this from web.
Here's the output of the command
keytool -list -keystore <path>

I'm trying to compile this app to Android 4.2.2, but I tried and want to make it work in 2.2 and above.
Here's the Android tab of the properties window just to make sure:

See the snapshot. You did not add Google Play Services library that is require for displaying Google Android Map V2. Please download and add that library and then try again.
Please also see the target. Your target is 4.2.2 and your are accessing it on 2.2. Change the target to 2.2 and use support fragment.
Thanks,
I have solved this issue,
Open your Google APIs Console
Choose API Access
Edit allowed Android apps from your API Key
Change the package name with your package name
Example: 00:06:A5:0E:04:A2:1E:8F:FE:6B:7F:46:23:C3:xx:xx:xx:xx:xx:xx;com.example.androidmapview
You are missing permissions and meta-data for API KEY.
Read this carefully: https://developers.google.com/maps/documentation/android/start
Working with android mapapi v2 ,the main reason is you must add play service to your app,like below :
<permission
android:name="com.example.androidmapview.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.androidmapview.permission.MAPS_RECEIVE" />
Use fragment class in Layout:
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>
And change your manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.androidmapview"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="16" />
<permission
android:name="com.example.androidmapview.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="com.example.androidmapview.permission.MAPS_RECEIVE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.example.androidmapview.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>
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"></meta-data>
</application>
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />
</manifest>
in activity:
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment;
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SupportMapFragment fragment = new SupportMapFragment();
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, fragment).commit();
}
}
For more info check the link which will explain you in details about api v2
I solved my blank screen problem with zoom in/out buttons like that.(it happens after I changed my package name)
Delete the keystore file
Create a new keystore file
Get SHA1 fingerprint
Go to API Console
Create a new Android App.
Paste your fingerprint
Use the given API Key in your Manifest File
That worked for me
