Answer 2

If you are specifying the property in your pom you shouldn't have it declared in a separate file as well. Conversely, if you want to specify it in a separate file you shouldn't declare it in your POM.

However, I am not sure exactly what you are trying to do - maven properties are only valid within your pom file and are for use during the build process. You can't access them from within your application. Android/java have no idea they exist and can't see them, so the reason you see the ${helloFromPOM} in your code instead of MY PROPERTY is that android/java is just displaying the text - it doesn't know that it stands for a property and it has no way to parse it into a variable or other value.

Sometimes it's caused by an inappropriate platform version. Try to set it right in your pom file. Look for smthg like

<sdk>
    <platform>17</platform>
</sdk>
