App not installed

Hey Guys,

I have build signed.apk file using this doc, but when i installed signed.apk after installing getting error msg " App not installed"
Could you please help me solve this issue?


For android: Checked that you got apache ant? in my case it wasnt, and the app installation was failing. . After the install of ant the app got installed without problems.

Thanks @lfelisiak,

I’m beginner and not aware with apache ant. so can you please tell me step-by-step?
I have build .apk file using "ionic build --release android"
This generates an android-release-unsigned.apk; but I got the parse error(There was a problem parsing the package) when i try to install it.


If I do only a ionic build android then it creates the debug version and I can install it ok.
