Can not get the same signature from the keystore

Question

I am developing an app on eclipse. But I am not going to publish it on Play Store, users will take copies directly from me or my website.

When I try to update my app, it says there is another app installed with the same name. Uninstalling does not matter for my app. But it doesn't update without uninstalling the previous one. I just don't want users to complain about it.

Problem is; I am using the same key store and password for signing the app, but using different computers (actually three or four computers).

• Is it the cause of different signatures?
• If so, How can I get same signatures from different computers using the same key store stored in flash disk?

Thank you all.

you will sign your app in a different computer but be sure to really use the same Keystore file! =).

Remember, you have to change the android:versionCode into the AndroidManifest.xml for the newer version of your application.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.threadsample"
    android:versionCode="12"
    android:versionName="2.1" >
