Android - Random XML Inflate Errors

Stack overflow has been great to me in the past week in developing my first android app. Im having a very random problem though. Sometimes my app has a problem inflating the XML layout files. It's not one particular one, but when I change an XML file, it randomly force closes because I need to define layout_height on line 18. At least that's what it usually tells me. I normally just rewrite that View tag and it works fine but I would like some insight on to whats going on. Any help is appreciated!

Heres a sample XML that FCs because of the problem above.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/bg"
    >
<TextView
    android:id="@+id/noteFormDateTimeTest"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#000000"
    android:textStyle="bold"
    android:textSize="26dp" />
<TextView
    android:id="@+id/noteFormContact"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" <!--This would be line 18-->
    android:textColor="#000000"
    android:textStyle="bold"
    android:textSize="26dp" 
    android:layout_below="@id/noteFormDateTimeTest"/>
<EditText
    android:id="@+id/noteFormTitle"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" 
    android:hint="Note Title"
    android:layout_below="@id/noteFormContact"/>
<EditText
    android:id="@+id/noteFormBody"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:singleLine="false"
    android:lines="15"
    android:gravity="top"
    android:hint="Enter Text Here"
    android:layout_below="@id/noteFormTitle" />
<View 
    android:id="@+id/helper" 
    android:layout_width="0dp"
    android:layout_height="0dp" 
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true" />
<Button
    android:id="@+id/noteFormSave"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Save"
    android:layout_alignParentBottom="true"
    android:layout_toLeftOf="@id/helper"/>
<Button
    android:id="@+id/noteFormDiscard"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:text="Discard"
    android:layout_alignParentBottom="true"
    android:layout_toRightOf="@id/helper"/>
</RelativeLayout>

Brian,

Perhaps problem is with dateTimeValue you passed it to CreateNote() without ever initializing it.

The problem can be in your build process. Just make cleaning before making project should solve your problems.
