All right, here's a potential workaround, although I don't know if this did it or something else was responsible, so I'd like to keep the question active. For me, what I did was make a new emulator for the latest version of Android and then test it in Meerkat. Then I went back and tried the emulators in Meerkat (that I had previously made in Giraffe) and they seemed to work now. Not sure if coincidence or related, would still probably be interested in any potential feedback on this.
