Google Maps API v2 suddenly stopped working

Question

Everything was working great when Google Maps API v2 suddenly stopped working. And after a full 1 day and 1 night try I am still not able to bring it back. I made a simple application and it still doesn't work.

My files are as follows:

package com.azimbunafar.apps.japanallthingsdirectory;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

    public class MapActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map);
    }
}

The Layout file is

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

The Manifest file is:

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.azimbunafar.apps.japanallthingsdirectory"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="17" />

    <permission
        android:name="com.azimbunafar.apps.japanallthingsdirectory.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="com.azimbunafar.apps.japanallthingsdirectory.permission.MAPS_RECEIVE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <!--

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

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyCzxLRmQvoRhtxVKHcaPAacknQfJVtXSoQ" />

        <activity
            android:name="com.azimbunafar.apps.japanallthingsdirectory.MapActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

The error I get in LogCat is

I have searched every single thread on "Failed to load map. Error contacting Google servers" Error. But nothing seems to work.

I will appreciate any kind of solution or suggestion. If you need more information about my application please let me know.

Answer 1

You should check your permission, I had the same problem and it was because i deleted one permission. Be sure to have all this permissions in the manifest.

 <uses-permission android:name="com.example.adroidtest.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.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<!--
 The following two permissions are not required to use
 Google Maps Android API v2, but are recommended.
-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Hope it helps you.
