exporting an apk: differences in files created

valerio_sperati

Hi!

1) Problem: I need to give to another user my application "foo", so that he can install it on his Android tablet.

2) What I did: I pressed the button "Export package", that correctly created the folder "Android" inside my sketch folder. Inside "Android/bin" I could find 3 different apk files: foo_release_signed.apk; foo_release_signed_aligned.apk; foo_release_unsigned.apk. Then I sent the user the file foo_release_signed.apk. He was able to install it and run it (after disabling some security control).

3) Question: Please, can anyone explain me the differences between the 3 apk files? It is the first time I run an operation like this, I'm wondering if I sent the user the right file (it works, ok, but maybe it is better to share another file, I do not know).

Thanks a lot! Valerio

@valerio_sperati::: in order to transmit your app to end users you have to export it as a signed package zipalign is the way that android use to optimize the data for your app

https://developer.android.com/studio/command-line/zipalign.html

so in your case=== foo_release_signed_aligned.apk
