Android: automatically choose debug/release Maps v2 api key?

Question

I'm using Google Maps v2 API in my project. In Google Maps v2 the debug/release API key is defined in AndroidManifest.xml. I have seen the link but in that map key is defined in a xml layout file not in AndroidManifest.xml. So can I define both debug and release keys for my project in AndroidManifest.xml?

I want something like this in AndroidManifest.xml:

If debug mode:

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

If release mode:

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

Answer 1

I solved this issue using this steps:

In Google Developer API Console

1. Click on Create New Android key...
2. In cmd.exe/Terminal: keytool -list -v -keystore mystore.keystore
3. Password: android
4. Now enter SHA1 key;package name for debug and press enter
5. Enter SHA1 key;package name for release
6. Click on Create

Now use this API key your project

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