I have an HTC wildfire. I am currently developing an application which I am consistently testing on my phone. Since yesterday for some reason I am not able to install any apk of that particular app that I am building. The usual method of installation I use is download to SD card and then install from there. Other apps get installed with this process but not my app. I am able to download and install my app from the market. I have tried deleting all information from the phone regarding the app i.e cache etc but still doesnt work. Not sure if the phone has blocked my app ? Can it do that ..? PS: My app name is 360, which is a panoramic app on the android app, just in case.
