I created a basic Android app as an Internship. Created its APK and tried to run on my mobile by connecting it to the Laptop by USB cable and used as an emulator, it's working perfectly. My Android OS version is Oreo, I tried the same to do on Lollypop and still it's getting executed.
The problem arrives when I am sending that APK via e-mail and trying to directly install on the device, it's giving me this error
There was Problem in Parsing the Package
I don't know what is happening as it is getting executed directly from Android Studio.I kept minimum SDK as 15.
Please help me out.
