I guess that's why "device must have Google Play services version 11 or higher to use the Google Fonts provider".

[Mygod]

I can't reproduce this issue on Android API 19 (no Google API) emulator. And I can't find a emulator image for API 25 without Google API.

[madeye]

Hmm, without Google API, how could it work?

[pexcn]

我那个 API 25 的模拟器是有 Google APIs 的.

[Mygod]

On my side, it just uses a regular font instead. We could use a hardcoded
xml font instead to solve that issue (and possibly this).

[madeye]

@Mygod Do you mean we just roll back to "the old way"?

[Mygod]

@madeye Not exactly. It means we will use font support in support library.

[madeye]

Please try 6c89207.

[pexcn]

好，感谢 dalao, 周一再试试了

[Mygod]

@madeye I think the old one is already using fonts thru support lib. See stack trace.

[madeye]

Maybe we also need to handle that exception in our code, since it looks a bug of Google.

[Mygod]

@madeye I can reproduce the crash with airplane mode on in virtual device. https://github.com/shadowsocks/shadowsocks-android/commit/6c89207eff94c90a2ac20a82a7eeac1a12c6210d didn't fix it. Let's use xml font instead.
