Bitmap Width and Height with Android 4

Question

I have carema.png and carema_sel.png images in drawable-hdpi and a carema_btn.xml layout file. On Android 2.2 and 2.3 devices, things appear normal, but in android 4.0, the button is too big. Here is my layout:

<?xml version="1.0" encoding="utf-8"?> 
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
         <item android:state_enabled="false" android:drawable="@drawable/camera"/>
         <item android:state_enabled="true" android:state_pressed="true" android:drawable="@drawable/camera_sel" />
         <item android:state_enabled="true" android:state_focused="true" android:drawable="@drawable/camera_sel" />
         <item android:state_enabled="true" android:drawable="@drawable/camera"/>
    </selector>

    <Button
        android:id="@+id/cameraButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:background="@drawable/camera_btn" />

Why is the button appearing too large in Android 4.0?

Have you find why this occurs ? For some reason, button behaves this way in my case too, yet textView is fine. — android developer, Apr 11 '13 at 08:58

Do you have the png images only in hdpi ? IF you want to support multiple screen sizes, you should provide also ldpi, mdpi, and xhdpi versions of your image.

If the screen of your 4.0 device has other dimensions than your 2.2 / 2.3 devices, this could be the problem.
