[Java for Android App Development] edjix:
I have decided to start learning the development side of Android, and have started on develepor.android.com. I've been following the tutorials to build the first app on there, using Android Studio. I got it to work fine, up until following the Starting Another Activity part. I guess I changed something in AndroidManifest.xml, and it absolutely will not compile now. I've ran the code validator numerous times, tried to compile it, googled for awhile, and it seems I have what it's asking for, but obviously not. the AndroidManifest.xml is:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="schemas.android/apk/res-auto"
package="learning.application">

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">

<activity
android:name=".MyActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action
android:name="android.intent.action.MAIN" />

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

<activity
android:name=".DisplayMessageActivity"
android:label="@string/title_activity_display_message"
android:parentActivityName=".MyActivity"
android:theme="@style/AppTheme.NoActionBar">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="learning.application.com.MyActivity" />
</activity>
</application>

</manifest>

This produces an error:

Merging main manifest AndroidStudioProjects/learning.app/app/src/main/AndroidManifest.xml

I've tried putting the package name in the android:name="foo" for the activity, and can't seem to figure out what I'm missing, I've googled around, and can't figure this thing out....apparently I'm that talented to screw up right off the bat, or not googling/understanding this? Can anyone show me what I'm missing?

**EDIT** Apparently it thinks that in the code is posting outside links, modified the top of AndroidManifest code so it'd let me post,
