Downloading ppsspp versions straight to Android

[AlphaKennyTime]

I'm not sure if this has been addressed before but if I try to download any of the ppsspp git versions straight to my 4.4.2 Galaxy S3 I just get an apk that's about 762kb. I get an error when installing. I always have to download to a computer then transfer the apk to my phone. It's obviously a very minor issue but I'm just wondering if there's a way to get them straight to my phone.
