The emulator won't show the "Hello world" app. There are two errors that I can't fix. Can you please help me?

The error messages are as follows:

1) Error:(8) Error parsing XML: not well-formed (invalid token)

2)Error:Execution failed for task ':app:processDebugResources'.

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\OrlaMcGreal\AppData\Local\Android\sdk\build-tools\22.0.1\aapt.exe'' finished with non-zero exit value 1

The code where these errors relate to is here:

android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".FunFactsActivity"

<TextView android:text="@string/hello_world" android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

<RelativeLayout>

How do I fix these errors?

Thanks in advance!

The first thing I notice is that you don't have any header at the top. So all the text looks dark.

I don't know if you are using android.support.v7 or v4 but you need some osrt of header at the top like in my example below. This should be automatically created for you when you create a new layout. Is this not happening? If you are using version 4. You can simply copy the header I show in the example below. Notice how all my code in my example is active. That is what yours needs to look like. 

<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    tools:context=".FunFactsActivity" 

<TextView android:text="@string/hello_world" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"/>

Hi Orla,

To me that looks like a partial xml file. Would you mind posting the entire thing?

Gradle exception meaning in a The manifest.xml most likely. Which aligns with the malformed xml. Without the file like Jon Kussmann said. Its hard to know the exact problem without seeing the code. But look at the manifest.xml

Hey guys, Here it is:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".FunFactsActivity"

<TextView android:text="@string/hello_world" android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

<RelativeLayout>
