ProgressBar Circle shows no progress on android L (API 21)

Question

I have a circular ProgressBar to count down time. It workes perfectly on kitkat and before, but on android L it always shows a full circle no matter what progress I set.

Answer 1

The default value for android:useLevel under the tag incorrectly changed to false in the L Preview build. You can work around this by explicitly setting it to true.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape
            ...
            android:useLevel="true">
            <solid
                ...
