Hello everyone I created an Android application which displays a google map and sets markers on the google map. The application is working fine until I sign that application.

My problem is after signing the application google map is not being loaded.

What is the problem?

I am using Google Api v2 and map fragment to view the map.

Here is my manifest code....

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

<uses-sdk
    android:minSdkVersion="4"
    android:targetSdkVersion="19" />



 <permission 
    android:name="example.tranzlogix_map.permission.MAPS_RECEIVE" 
    android:protectionLevel="signature"></permission>

<uses-permission 
    android:name="example.tranzlogix_map.permission.MAPS_RECEIVE"/>
<uses-permission 
    android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<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-feature
    android:glEsVersion="0x00020000"
    android:required="true"/>



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

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyB6ut74Pvg8T2rs7jg5GSjD6Es4beyxSYI"/>


    <activity
        android:name="example.tranzlogix_map.LoginActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

    <activity
        android:name="example.tranzlogix_map.HelpActivity"
        android:label="@string/app_name" >

    </activity>
      <activity
        android:name="example.tranzlogix_map.MainActivity"
        android:label="@string/app_name" >

       </activity>


     </application>

  </manifest>

You probably still have your Google maps API key based on the SHA1 hash of the DEBUG certificate.

After signing the app for release you will have to set your Maps API key based on the SHA1 hash of the RELEASE Certificate.

See displaying the release certificate fingerprint
https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2

Obtain the Release SHA1 hash ,generate the API Key and set this as the key in the manifest

add this meta_data under your meta_data:

<meta-data android:name="com.google.android.gms.version" 
android:value="@integer/google_play_services_version" />

and add this permission:

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

-------------Edit---------------

here is your Manifest, with the needed meta and Permissions as well. If you still have an error please add it to the question as edited

looking at this the minimum API level for map is 8 so you need to change minSdkVersion to 8

Did you try importing 'google-play-services'? Problem can occur in importing a different version of google-play-services'. I imported v29 first and was not working so sometimes you just have to stay low. I got it on using v12.
