可以通过 USB 电缆从 Android Studio 发送“发布”版本吗？

Question

Using Android Studio 0.6.1 (actually on OSX), normally I have build variant set on "debug".

I have a phone plugged in "Connected as a media device". I click the "Run" button up top.

Everything works fantastically well.

However. Say I change this to "release" ...

it seems impossible, to now send it over the USB to the phone?

I understand that to publish to the playstore, I use "release" and use "build signed apk", using the password for the keystone. That works perfectly.

SoBut can I just "leave it on" "release" mode while working with the tethered phones?

(With iOS development for example, the "debug" setting is just annoying and sucks, and you can just leave it on "release" all the time, basically. Indeed you can just delete the "debug" variant.)

thanks, Android aces!!

Here's the error that appears if you try to send a "release" build over the USB cable to a tethered phone.

Answer 1

The Android system requires that all installed applications be digitally signed with a certificate whose private key is held by the application's developer.

Have you set up a key-store for signing the release build?

for details using gradle see how-to-create-a-release-signed-apk-file-using-gradle

With android studio 0.5.9 you can use Module settings [F4]/app signing to define the key store.
