Question

Using this page, http://developer.android.com/sdk/compatibility-library.html , I have installed the Android Support Package, added a libs folder in my project, moved the JAR file into my libs directory, and clicked ‘Add to Build Path’ but I am still getting the error :

com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup
Exception details are logged in Window > Show View > Error Log
The following classes could not be found:
- GridLayout (Fix Build Path, Edit XML)

Here is my XML file…

<?xml version="1.0" encoding="UTF-8"?>
<GridLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:columnCount="2"
    android:rowCount="13" >

    <TextView
        android:layout_gravity="fill_horizontal"
        android:text="SN : " />

    <TextView
        android:id="@+id/snTextView"
        android:layout_gravity="fill_horizontal" />


    <TextView
        android:layout_gravity="fill_horizontal"
        android:text="Ver : " />

    <TextView
        android:id="@+id/verTextView"
        android:layout_gravity="fill_horizontal" />

    <TextView
        android:layout_gravity="fill_horizontal"
        android:text="Type : " />

    <TextView
        android:id="@+id/typeTextView"
        android:layout_gravity="fill_horizontal" />

    <TextView
        android:layout_gravity="fill_horizontal"
        android:text="OD : " />

    <TextView
        android:id="@+id/odTextView"
        android:layout_gravity="fill_horizontal" />

    <TextView
        android:text="Closing Mode"
        android:layout_gravity="fill_horizontal" />

    <TextView
        android:id="@+id/closingModeTextView"
        android:layout_gravity="fill_horizontal" />

    <TextView
        android:text="CT : "
        android:layout_gravity="fill_horizontal" />

</GridLayout>

GridLayout is only available in the most recent release compatibility package. You won’t be able to use GridLayout for your project unless your minSdkVersion is set to 7 or above.
