Resizing issue in android

Question

I have a layout that is displayed in an activity. When i run it on the clique it takes up the whole screen but when i run it on the droid 3 there is a black bar at the bottom and sides. How do i make it so it takes up the whole screen? I thought android was suppose to do that for you?

update:

I am just setting the contentView of the Activity like this:

activity.setContentView(R.layout.home);

Heres the XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/home_screen_lay"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/home_screen">
</RelativeLayout>

Heres my manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.myapp"
    android:versionCode="1"
    android:versionName="1.0">
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Viewer"
            android:label="@string/app_name"
            android:configChanges="orientation|keyboard|keyboardHidden"
            android:screenOrientation="landscape">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

Heres a picture:

you can see where it won't resize.

if anyone needs anymore info i can update again.

I had a problem like this once. It was because the min or target sdk wasn't set to at least level 3 in the AndroidManifest. Something like this: <uses-sdk android:targetSdkVersion="7" /> I'm guessing level 1 doesn't handle higher pixel screens.
