Whenever I try to install the eBay app from the play store I get a -24 error code: "unknown error when installing application". I have googled the error and I cannot find anything relating to this. Anyone know what this error is and how to fix it? I can install other apps. I have an S4 on Kit Kat (4.4.2). I have forced stopped the play store and cleared the data on play services and play store.
