[Android] Crash on API 20 and below on LocationComponent

[chloekraw]

User has reported the following info. Sounds similar to #14889.

Description

There is an IllegalArgumentException being thrown from LocationLayerController.java:styleShadow(). This only happens on API 20 and below because API 21 fixed the root cause of this issue , while API 20 and below will pass an invalid radius to RadialGradient without this if check.

This is causing a crash for some users on older devices, particularly in some sort of windowed state where the radius could default to having a 0 or negative radius given the xml defines the radius in dp.

To fix this, perhaps the styleShadow method should be wrapped in a try catch. I'm not sure if there's another way to fix this so the shadow is always present even for users in API 20 and below, since a try-catch may prevent future draws if the style.addImage call is never fired to actually add the bitmap for the shadow to the map.

Steps to reproduce

Unable to reproduce.

Expected behavior

A shadow appears on the LocationComponent for older devices

Actual behavior

IllegalArgumentException is thrown in Android drawable infra code, typically causing a total app crash.

Configuration

Android API 20 and below will be affected, not sure if any specific architectures are susceptible to this bug but it seems to be related to some sort of windowed capability.

This mostly occurs on Android 4.4.4 with a peak in Lenovo P70-A devices.
