Android: How to track down the origin of a InflateException?

Question

While starting my application I get the following warning in Logcat:

04-09 10:28:17.830: WARN/WindowManager(52): Exception when adding starting window

My Application starts with the following splash screen:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:windowBackground="@color/white" android:background="@color/white"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:foregroundGravity="center">

    <ImageView android:id="@+id/ImageView01"
        android:layout_width="fill_parent" android:layout_height="fill_parent"
        android:adjustViewBounds="true" android:scaleType="centerInside"
        android:src="@drawable/splash" android:layout_gravity="center" />


</ScrollView>

Splash is the image that is shown in the splash screen. I have those four folders with for storing drawables in my app:

/res/drawable-hdpi
/res/drawable-ldpi
/res/drawable-mdpi
/res/drawable-nodpi

the splash image has its own version in the first three of them and is displayed properly. Removing the src property from the ImageView removes the image but not the exception.

I'm a little bit lost with where to look for the cause of the exception. I even don't know if this is really an issue in this layout file etc.

How would you go about finding the cause for this warning?

I had a similar problem when setting a nondrawable (dimention in my case) on a style attribute that expected a drawable. I would expect the builder (XML sanitiser?) to warn you before a build happens. — Diederik

I had the same exact error. The only xml line 24 that made any sense was my application manifest which happened to be the closing tag for application. I traced it down to my custom theme I was adding for the app -- I was not defining the parent of the style. All I needed to do was add parent="android:Theme" to my style and my error went away.

<style name="MyTheme" parent="android:Theme">
...
</style>
