Crash when using color values from styles.

[dmitvitalii]

I'm trying to set colors like that:

app:fillColor="?attr/colorAccent"
app:pageColor="?attr/colorPrimary"
app:strokeColor="?attr/colorPrimary"

It worked before, but now it throws:

android.view.InflateException: Binary XML file line #16: Binary XML file line #17: Error inflating class com.viewpagerindicator.CirclePageIndicator
caused by: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x1d

I've tried to set @color/color_primary values and '#ff00ff' color hex values: the same issue.

As a workaround: I set all needed colors in runtime by calling setFillColor(), setPageColor() and setStrokeColor() respectively.

minSdkVersion 21
targetSdkVersion 26
buildToolsVersion "26.0.0"

I have the same issue. It happened when I upgraded Gradle plugin to 3.0.0-beta4

[harry248]

Same here after updating project to new Android Plugin.

[janbolat]

Same here after updating to Android Studio 3 RC1, Gradle 4, Android Gradle plugin 3 rc2

@janbolat same here too

Does anyone know a good alternative to this library? As it is no longer maintained I don't think we will get a fix for this anytime soon...

[javieramp]

Same too.
My solution is how it say dmitvitalii, removing --> app:fillColor="@color/blue"
and set it programmatically mIndicator.setFillColor(ContextCompat.getColor(context, R.color.blue));

This Stackoverflow Answer worked well for me: https://stackoverflow.com/a/46950028/1350902

In my case, I had to set all app: attributes programmatically

[eriknyk]

@jannisveerkamp question please,
did you added something else than: compile 'com.github.JakeWharton:ViewPagerIndicator:2.4.1' ?

because I'm getting an error

Error:(80, 13) Failed to resolve: com.github.JakeWharton:ViewPagerIndicator:2.4.1

[kotucz]

This is probably JitPack syntax
compile 'com.github.JakeWharton:ViewPagerIndicator:2.4.1'
you should add JitPack repository

repositories {
    maven { url "https://jitpack.io" }
}

but in my case it caused error somewhere else, so I solved this by setting the style programatically

[eriknyk]

thank you @kotucz adding jitpack.io worked!

[lorenzopolidori]

compile 'com.github.JakeWharton:ViewPagerIndicator:2.4.1' using jitpack.io didn't work for me with the android gradle plugin 3.0.

Instead I had to set programmatically all the view attributes that I previously set in the xml layout with cpi: (or app:) attributes.

Example

<com.viewpagerindicator.CirclePageIndicator
    cpi:fillColor="@color/azure"
    cpi:pageColor="@color/white"
    cpi:radius="4dp"
    cpi:snap="true"
    cpi:strokeWidth="0dp" />

I removed all the cpi: attributes and set them all programmatically:

circlePageIndicator.setFillColor(ContextCompat.getColor(getContext(), R.color.azure));
circlePageIndicator.setPageColor(ContextCompat.getColor(getContext(), R.color.white));
circlePageIndicator.setRadius((int) (4 * Resources.getSystem().getDisplayMetrics().density));
circlePageIndicator.setSnap(true);
circlePageIndicator.setStrokeWidth(0);

targetSdkVersion is 26
Is this a Compatibility problem?
