No support for XML based drawables

[alex2069]

We have a placeholder shape drawable (or sometimes shown directly as .load(R.drawable.abc)) which fails to display. The onException listener is called, but e is null.

The logs contain only:

com.example.app D/skia﹕ --- SkImageDecoder::Factory returned null

Glide: 3.5.2
Tested on Genymotion v4.4.2

The drawable:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
    <solid android:color="#ffabcdef"/>
</shape>

Not totally surprising, BitmapFactory will handle image based drawables, but not shapes or ripples etc. We may be able to fix this in 4.0, but probably not before.

Here's a list of currently known (and wanted non-bitmap drawables):

• Bitmap alias: Loading an alias'd drawable.xml does not work #683
• NinePatch (.9.png): NinePatchDrawable can't be loaded #786, Can glide add a .9 picture as a placeholder  #814
• Vector: Glide with VectorDrawables #794
• Shapes: No support for XML based drawables #350 (this issue)
• already in-memory Bitmap/Drawable: Consider supporting Bitmaps/Drawables for consistency #122 (only loosely related, not duplicate)
• StateListDrawable (https://groups.google.com/d/msg/glidelibrary/CcfLyt_Y3H0/pMqGIr9GDQAJ)
