I have a problem, I was working on an application using Ionic, all normal until the time to try the apk, when I pass it to my cell phone and try to install it, it does not install, the only error it gives me is the message of "application not installed" I do not know what I do wrong because compiling does not give me any error. I have used several commands for the compilation, both read in forums and on the same ionic page, which let me compile the apk but they all give me the same error. Any advice or idea of how it is fixed?
