+1, and everyone using the latest version of the library has exactly the same issue.

This seems to be a reoccurrence of issue #30.
I thought this was fixed by adding the "isInEditMode" fix.
What happened?

[castorflex]

I just uploaded a snapshot that should fix the problem. Can you confirm that it's ok for you before I push it on maven central?
You will just have to add the following to your build.gradle to use the snapshots

repositories {
    mavenCentral()
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
}
dependencies {
    compile 'com.github.castorflex.smoothprogressbar:library:1.1.0-SNAPSHOT@aar'
}

[Mithrandir21]

Just added the the lines needed, did "Clean project" and "Rebuild project".
I'm not getting the same error as before and there is a (Android Standard) progress bar shown in the preview, but now there seems to be a message about a missing color.

This is the View I have tried to add (also tried with the first example in the readme page, but got the same result):

<fr.castorflex.android.smoothprogressbar.SmoothProgressBar
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

Here is the top part of the error message in the Preview page:

Missing styles. Is the correct theme chosen for this layout?  Use the Theme combo box above the layout to choose a different layout, or fix the theme style references. 

The following classes could not be instantiated:
- fr.castorflex.android.smoothprogressbar.SmoothProgressBar (Open Class, Show Exception)
 Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE

Maybe I'm doing something wrong. Let me know if you need me to test anything else.

I've juste re-upload a 1.1.0-SNAPSHOT version, it should be ok now. You will likely need to clear your local maven cache before.
