Rust log is print to stderr. But we want them to print to android_log on android.

Checked logout of attachment 9002686 [details] [diff] [review] by enabling WebRender on android. Example of logout was like the following > 08-21 18:06:23.606 4759 4891 E webrender_bindings::bindings: WebRender - OpenGL version new OpenGL ES 3.2 V@251.0 (GIT@8aaecb6, Ib515ec08c2) (Date:10/19/17)

Comment on attachment 9002686 [details] [diff] [review] patch - Forward rust log to android_log on android Review of attachment 9002686 [details] [diff] [review]: ----------------------------------------------------------------- It seems it would be cleaner to define a log_out function, with two variants (one android, one not(android)), and have have log() delegate to it. That way, we avoid the duplication of maybe_log_to_gfx_critical_note. r=me with that change, assuming you're confident in the semantics of the _android_log_write stuff (I didn't double-check it).

Address the comment.
