    Well I encountered a problem recently that a lot of people were complaining about when I Googled, which is a lot of the time I like to share some basic console programs with only have functional java installed, and on windows 7 the command I used to use to open command prompt [Runnable.getRunnable().exec("exec /k run.bat")] no longer works due to security precautions.

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_height="match_parent"
        android:orientation="vertical" >
