Answer 1

Your crash is caused by the following:
Caused by: java.lang.UnsupportedOperationException: Can't convert to
dimension: type=0x1 at
android.content.res.TypedArray.getDimensionPixelSize
So the problem is in one of your dimensions:
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
I can guess, that you used wrong dimension type, e.g. sp instead of dp
Here is how a right dimension should look:
<dimen name="activity_vertical_margin">36dp</dimen>
Also please ensure your dimension is defined in an xml in the valuesfolder as it mentioned in this answer
