Meta data

In AndroidManifest.xml, you can define meta data 

<meta-data android:name="com.atmarkplant.key" android:value="Hello" />

How to get using code

String key = "";
try {
   ApplicationInfo appInfo = context.getPackageManager().getApplicationInfo(
   context.getPackageName(), PackageManager.GET_META_DATA);   
   if (appInfo.metaData != null) {
      key = appInfo.metaData.getString("com.atmarkplant.key");
   }
}
catch  (PackageManager.NameNotFoundException oops) { 
     oops.printStackTrace();
}

You need context from anywhere.
And the argument is name.
