Question

When trying to add a custom image to a ImageButton, I get the following error:

E/AndroidRuntime(3304): Caused by: java.io.FileNotFoundException: res/drawable/btn_default.xml

This Works:

<ImageButton
    android:id="@+id/imageButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@android:drawable/btn_plus" />

This does not:

<ImageButton
    android:id="@+id/imageButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/elec" />

On the designer I can see the image fine on the button, but as soon as I try to run it, I get the above error. The elec.png file is in drawable-hdpi.

Burned 3 hours trying to find the problem. Any help really appreciated!

Answer 1

In the end, it turned out that my emulator was somehow corrupted. The code works perfectly on a real device and on a newly generated emulator.
