Dotted line is actually not dotted when app is running on real Android device
android, android-drawable
Solution
This is most likely related to hardware acceleration: Dashed lines are not supported in GL mode.
Its documented here: https://code.google.com/p/android/issues/detail?id=29944
Turn off your HW-acceleration in your AndroidManifest.xml like this:
android:hardwareAccelerated="false"
or:
myView.setLayerType(View.LAYER_TYPE_SOFTWARE, null)

Problem
in my app I use XML defined vertical dotted line. ``` <?xml version="1.0" encoding="utf-8"?> <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:fromDegrees="90" android:toDegrees="90"> <shape android:shape="line"> <stroke android:width="1dp" android:color="@color/light_gray" android:dashWidth="2dp" android:dashGap="4dp" /> </shape> ``` When I am nitpicking my layout in Android Studio, the line is rendered properly dotted, as it should, but problem comes out when I run the app on real device. The line is just solid with no gaps. What could be the problem? I tried many different devices including those running latest 4.3 Android. It look everywhere the same.
