I have been trying to app a Google Map in my Android app using the v2 API for the past two days, with no success. All I get every time is a
Google Maps Android API(16603): Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors).
I have followed Google's setup tutorial (https://developers.google.com/maps/documentation/android/start), tried multiple times with different projects in different workspaces, tried different Google accounts, gone through various answers and suggestions here in StackOverflow, but to no avail.
I am using Eclipse 4.2.2 with Android SDK Tools 22.01 and I have installed Google Play services (rev. 7), also I have imported google-play-services_lib into my workspace and added a reference to that to my android project.
Here is my code:
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.googlemapdemo"

</activity>
<meta-data

android:value="my_api_key" />
</application>
</manifest>
activity_main.xml:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/the_map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.SupportMapFragment"
/>
MainActivity.java
package com.example.googlemapdemo;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Also I created an API Project on https://code.google.com/apis/console/ where I have enabled the Google Maps Android API v2 service. Then I obtained my SHA1 debug certificate fingerprint using
keytool -list -v -keystore "C:\Users\my_user_name\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
and entered that and the package name in the API console, got the API key and put it in the manifest (where my_api_key is). This procedure I repeated a number of times, regenerating the key but with the same result.
Could anyone help with this or suggest anything else I could try? Any help will be greatly appreciated!
