How to access metadata from AndroidManifest.xml in Xamarin.Froms

Question

I'm trying to access metadata from AndroidManifest.xml in Xamarin.Forms Android project.

I have this code:

var ai = CrossCurrentActivity.Current.Activity.PackageManager
            .GetApplicationInfo(CrossCurrentActivity.Current.Activity.PackageName,
                             PackageInfoFlags.MetaData);
var meta = ai.MetaData;

Problem is, that ai.Metadata is NULL. Any idea what is wrong? Thanks.

AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="auto" package="com.my.test.x2.x8" android:versionName="15.0" android:versionCode="15">
    <uses-sdk android:minSdkVersion="15" />
    <application android:label="MyApp" android:icon="@drawable/Icon"></application>
        <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <application>
        <meta-data android:name="MYENDPOINT" android:value="https://xxx.azurewebsites.net/" />
    </application>
</manifest>

Answer 1

Place your meta-data inside your existing application span and remove the other one, ie:

Example:

<application android:label="MyApp" android:icon="@drawable/Icon">
        <meta-data android:name="MYENDPOINT" android:value="https://xxx.azurewebsites.net/" />
</application>

Usage:

var bundle = PackageManager.GetApplicationInfo(PackageName, Android.Content.PM.PackageInfoFlags.MetaData).MetaData;
foreach (var key in bundle.KeySet())
{
    Log.Debug("SO", $"{key} : {bundle.GetString(key)}");
}

Output:

08-03 09:18:56.642  3519  3519 D SO      : MYENDPOINT : https://xxx.azurewebsites.net
