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?

Answer 1

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>

Answer 2

I had the same issue, and it was because I passed the application context instead of the activity context.

Answer 3

04-09 10:28:17.830: WARN/WindowManager(52): Caused by: android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path): TypedValue{t=0x2/d=0x1010059 a=-1

That line is the giveaway. The system isn't happy with one of your resources, probably a 'src' resource, probably android:src="@drawable/splash".

Answer 4

I got a similar error when running on a 2.0 emulator. I used a newer version of the API (version 7, 2.1-update1) and it worked.

Answer 5

The error is on line 24 of your XML file. What does that line contain? By the looks of the error message

android.view.InflateException: Binary XML file line #24: Error inflating class <unknown>

you're using a custom class and haven't defined something properly. For example, did you define the package name properly? Maybe its constructor isn't formatted? We'd have to see the XML file, specifically what's around line 24, to be able to give more info.

Answer 6

I know this is a bit late but I spent all day trying to figure this one out and finally with the help of this SO question I realized an XML file in the example I was trying out was using a feature from a later API and Lint wasn't catching it because the file hadn't changed. As soon as I did a random edit on the XML file and saved the file then the error about a later API showed up.

Answer 7

After so many hectic research on finding the answer that why App is crashing and why its not showing the logcat

I have just replaced this

android:configChanges="orientation|keyboardHidden"

to

android:configChanges="keyboardHidden|orientation|screenSize"

in the activity tag.
