Primiano, any idea how this is possible?

[ERROR:platform_font_android.cc(13)] Not implemented reached in static
gfx::PlatformFont* gfx::PlatformFont::CreateDefault()
[FATAL:ref_counted.h(312)] Assert failed: ptr_ != __null. 

?

The target is defined as (equal to ui_unittests_apk):

{
          'target_name': 'ui_base_unittests_apk',
          'type': 'none',
          'dependencies': [
            'ui_base_unittests',
          ],
          'variables': {
            'test_suite_name': 'ui_base_unittests',
          },
          'includes': [ '../../build/apk_test.gypi' ],
        },

Ick, sometimes C++ is unbelievable and unpredictable. :(

Again, I have no idea about UI, but this is clearly happening before you end up
calling:
https://code.google.com/p/chromium/codesearch#chromium/src/ui/gfx/platform_fo...
which is not implemented as returns null when you try to instantiate a 
PlatformFont on Android.
So, the first time you call Font::GetStyle(), the dereferencing of
platform_font_ causes the assert, because it has been initialized with a null
ptr.
Having said that, I have no idea about what is PlatformFont, why is not
implemented on Android.

Was this test ever running on Android before? By looking wildly at code in
chromium I see that:
1. ResourceBundle::InitDefaultFontList() calls 
gfx::FontList::SetDefaultFontDescription(std::string())
2. In turn, in font_list.cc it sets  g_default_font_description to an empty
string,
3. Therefore, when you try to call FontList::GetDefaultImpl(), it will
initialize the font with the default ctor (new FontListImpl(Font()),
ui/gfx/font_list.cc:41)
4. The default ctor of Font() calls initializes platform_font_ with
PlatformFont::CreateDefault()
5. PlatformFont::CreateDefault() is not implemented in Android.

Aha! Thanks for the investigation Primiano!

Got it! ResourceBundleTest.DelegateGetFontList is disabled for ui_unittests by:

https://code.google.com/p/chromium/codesearch#chromium/src/build/android/pyli...

I emailed Marcus about this on Jun 8, but for gfx unittests case.

There is a bug filed for this (http://crbug.com/339980), but I never got around.

I will get to this and the clobber issue.

Hopefully, it will improve this situation and avoid this subtle issues.
