eclipse – How to sign an android app for the market?

Posted by: admin June 15, 2020 Leave a comment

Questions:

I’ve recently released my first app on the market. I tried to install the app on my phone immediately after it was released. But when installing it I got an error saying that the app was wrongly signed. I also got lots of bad ratings for my app because other people couldn’t install it as well.

So my question is: how can I sign my app correctly? Is there any way to test the result before releasing the app on the market?

BTW: I used the built in function of eclipse to export the signed apk file.

How to&Answers:

Answer:

We can’t really tell you from afar what is wrong. Did you create your own self-signed certificate? The cert that comes with SDK is a debug certificate and should not be used for signing a production app.

I recommend you thoroughly read the docs about signing the apps.
