conflicting signature error...

[mauricedorris]

I just had my laptop crash and had to reload Basic4Android on a new 64 bit computer running windows 7.

I loaded everything, including the libraries and was able to open compile my app. But when I install it I get an error that says "An existing package by the same name with a conflicting signature is already installed."

Its not letting me update my app to a newer version unless I go through the process of manually un-installing first.

This worked just fine when I compiled on the other computer, which was 32 bit.

thanks for any help.

It is not related to 64 bit architecture.

Can you post the full dialog text?

 

[mauricedorris]

It only says what I already mentioned.

"An existing package by the same name with a conflicting signature is already installed."

This is not an error from the application, this is an error from android. I am running the toshiba thrive tablet.

What exactly is the "signature" its referring to? Is that something that I can control when I compile?

This error means that there is already an installed application with the same package name and a different sign key.

You should find it and uninstall it.

Of course I can find it and uninstall it.

But... I have a commercial application. When I issue updates,they are automatic and need to be able to overwrite the previous version without asking the user to manually uninstall.

So... how do I know what this sign key is? Can I control it?

This problem only started a couple of months ago when I compiled my application on a 64 bit computer. Prior to this computer, I used a 32 bit windows 7 computer for years and pushed out many upgrades without this messge.
Any help is appreciated

You should make sure to always sign with the same key file. You cannot find the key from the application itself.

OK.... I think I am remembering now. It has been a while since I recompiled the program.

I have the key file. But what happens if I forget the password and cannot load the keyfile. is there a way to decode it. I have the keystore file but don't remember.

 

[Erel]

You will not be able to use the key without the password. You cannot find the password from the key.

I am experiencing this problem? There is no app with the same names (I have saved and renamed the app), but get the same error?

I created an app called, notify.b4a. Saved and ran it and I get the error:-

"An existing package by the same name with a conflicting signature is already installed."

I copied the code and pasted into a new project called not.b4a and still get the same error when installing/testing?

There is no app on my phone named anything like these? What's up?

The app name is not important. Only the package name.

Hi Erel, that sprung to mind after going to bed

I just came on to delete the post.

Thanks anyway,
