@munsterlander thank you very much, it works now.

Hi, show me “check the Android manifest” and "review the keystore settings " but the changes I made did not modify these files. The error log is as follows:

Build error: Error building project source code

excuse my writing mistakes but I doesn’t mastered the language perfectly.

Hello everyone, I’m trying to compile a new version of my application for android and this always fails (compilation). The error started occurring last Friday and occurs whenever I try to compile for android. I have several applications in my IDE and all have the same problem. Something curious is that for ios versions have no difficulties. I appreciate any guidance, help or suggestions you can give me.

PS: upgraded version of cordova and still not achieve the expected result.
