android - Blur Mask Filters are not supported -

i have 1 custom class extends view class , in drawing custom bitmaps. problem whenever using class in xml, creates rendering problem.

here xml code :

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent">      <com.custom.drawingview         android:layout_width="wrap_content"         android:layout_height="wrap_content"/>  </relativelayout> 

there nothing else using in xml still error there, sharing screenshot it, check below.

in custom view class have used blurmaskfilter also

blurmaskfilter blurmaskfilter = new blurmaskfilter(5,             blurmaskfilter.blur.normal); 

as can see, not able see preview of layout , not component tree.

configuration :

android studio : 2.1.3 classpath 'com.android.tools.build:gradle:2.1.3'  compilesdkversion 24 buildtoolsversion "24.0.0" 

set android:hardwareaccelerated="false" on activity inandroidmanifest.xml this:

 <activity android:name=".myactivity" android:hardwareaccelerated="false"> 

its work fine me.
