Is it possible to compile for Android without a certificate?

Question

Android

There is no task to put the game on Google Play, I just want to play around, test it on my smartphone. How can this be done without a Google Play account (and paying $25)? HTML5 game, I want to assemble using CrossWalk.

Answer 1

Of course you can, it's even possible for OS X and iOS, especially for Android, when installing the SDK, a debug certificate is created, that is, your "self-made" digital signature and when compiling the APK it will be signed with it, if CrossWalk does not do this, you can manually use jarsigner, in general, it will work, you just need to allow "installation from third-party sources" on the device and it will work no worse than the signature of the Google Play developer.
