I am having this weird issue, for android OS below lollipop. When i click on Toolbar option menu or navigation drawer etc i am getting weird black edges as a highlight. Please see attached pic as an example
here is my theme for this activity (using AppCompactActivity as Base Activity)
<style name="NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
Found the issue, after the update my Android Plugin for Gradle was also updated to
2.2.0 alpha-3 but i changed it back to
classpath 'com.android.tools.build:gradle:2.1.0' // stable version.
With this minor tweak now this issue is resolved.
Note: You can either just wait for stable 2.2.0 version or try the next update.
