Until they solve the issue with the library

Create a file in res/layout-v11/magicretry_fragment.xml

Put the following code in it:

After wasting 3 hours, finally updating to 1.6.0 solved mine..

implementation 'com.payumoney.sdkui:plug-n-play:1.6.0'

Seems it's a problem in their SDK at the moment. The best solution would be to write to their support and ask to fix ASAP

<ProgressBar
            android:gravity="center"
            android:visibility="gone"
            android:id="@+id/magic_reload_progress"
            android:layout_centerInParent="true"
            style="?android:attr/android:progressBarStyleSmall"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

to

<ProgressBar
            android:gravity="center"
            android:visibility="gone"
            android:id="@+id/magic_reload_progress"
            android:layout_centerInParent="true"
            style="?android:attr/progressBarStyleSmall"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
