Auto merge of #1224 - gnzlbg:fix_android, r=gnzlbg

Re-enable android build jobs

This performs a `yes | ./sdk/tools/bin/sdkmanager --licenses` - the sole purpose of the `--licenses` flag is to allow the user to accept all licenses a priori, so that all other commands don't show any licenses.

For some reason, after all licenses have been accepted, the install step says that some licenses are still not accepted... so we need to accept those too... Why? I have no idea, and accepting licenses while installing still appears to make things hang a little, but it only does so for one non-accepted license, instead of for 5-6 like before, so now things do work.
