How can i get metadata in AndroidManifest.xml?

this is part of AndroidManifest.xml

<meta-data name="http_key" value="@string/string"></meta-data>

res/string.xml

<string name="http_key">sdfsfdsfsfsdfsdfsdfsdfsdfsd</string>

I can access metadata in java

ApplicationInfo appInfo = getPackageManager().getApplicationInfo(this.getPackageName(), PackageManager.GET_META_DATA); Bundle aBundle = appInfo.metaData; String aValue = aBundle.getString(“http_key”);

in Unity, How can i get metadata in AndroidManifest.xml?

AndroidJavaClass and AndroidJavaObject make it possible to access the PackageManager class.
It uses reflection, i found an example here:
