I have multiple developers working on a project. When they just run the program and then manually get the APK, our testers have to uninstall and re-install for each different developer that publishes the APK (something about debugging key). So I am wondering, what if I make them all use android tools> export unsigned application package? will that solve the problem?
You should create a new debug keystore for your team and check it in to our project repository. Then have each of them open Eclipse > Preferences > Android > Build and change the "default debug keystore" value to point to this new keystore. That way they all use the same debug keystore and you dont have to worry about signing debug builds yourself.
By default eclipse signs it with the default key which is different for different systems and on any android device if you try to reinstall it without first uninstalling it treats it as an update and it requires the update to be signed with the same key with which installed application is signed so follow what Karakuri suggested and it should solve your problem.

I have a app which I released many years ago on the market. It was originally done in Eclipse. Now i am making a new version of the app in Android studio. I still have the original key and password it was signed with.
Can i update the already published app made in eclipse with the new one im making in Android studio, as long as i use the same key it was signed with?
Thanks

Yes, you can.
Refer the documentation here.
If your app used a debug certificate in Eclipse ADT, Android Studio
continues to reference that certificate. Otherwise, the debug
configuration uses the Android Studio generated debug keystore, with a
known password and a default key with a known password located in
$HOME/.android/debug.keystore. The debug build type is set to use this
debug SigningConfig automatically when you run or debug your project
from Android Studio.
In release mode, Android Studio applies the release certificate used
in Eclipse ADT. If no release certificate was located during the
import process, add the release signing configuration to the
build.gradle file or use the Build > Generate Signed APK menu option
to open the Generate Signed APK Wizard. For more information about
signing your app, see Signing Your Applications.
Yup, you need to use the same key and the same package name.
I upgraded my Android studio to 1.4. Now when I'm deploying my app to my device I get the message that the device has an application with the same package but a different signature. How is this possible? I already did some research and I looked up my debug.keystore, but this hasn't changed since 13/03/2015. Anyone has any idea how I can fix this?
The problem is the keys that have been used to sign the APKs, by default if you are running directly from your IDE and opening your Emulator, the APK installed in the Emulator is signed with your debug-key(usually installed in ~/.android/debug.keystore), so if the previous APK was signed with a different key other than the one you are currently using you will always get the signatures conflict, in order to fix it, make sure you are using the very same key to sign both APKs, even if the previous APK was signed with a debug-key from another SDK, the keys will definitely be different.
Also if you don't know exactly what key was used before to sign the apk and yet you want to install the new version of your app, you can just uninstall the previous application and reinstall the new one.

Hope this Helps...
Debug builds are signed with the SDK keystore which is generated when you install the Android SDK. On Linux / OSX it is located at ~/.android/debug.keystore.
The message you had means that you have a debug build installed and you want to install an App Store build on it (or the other way around).
This can also happen when you deploy from a different machine.
i recently uploaded an app to the play store and needed to sign the apk.
Now i have 2 keystores: for debugging and for releasing.
my problem is, that i cant install my app with eclipse when i have installed the play/release signed apk, i have always to uninstall it.
my question is, how others manage that?
is it possible to disable verification when installing via 'adb install' or somehow use the release key as debug key in eclipse? eclipse wont accept it because it hasnt the default debug alias and passwords.

Yes you can define your custom (release) debug keystore as default.
In eclipse go to Window --> Preference --> Android --> Build copy the path of your keystore.
I've been working on some updates to an existing application I have in Google Play. The newer version of the application makes some changes to the application database. The problem I'm having is that I can't figure out how best to test the new update. Eclipse signs my "devel" package with debug.keystore (I presume) while the installed application from GP was signed with my release.keystore so I get the error message "Re-installation failed due to different application signatures” when I try to "run" my changes within Eclipse for debugging.
It's weird because I can download the 'release' apk from my company website and side-load it. This seems to ignore the signing even though the apk from GP and the one side-loaded are the same file.
If I go into Eclipse's Windows > Preferences > Android > Build and enter my release.keystore in under "custom debug keystore" (to get around the key signing descrepency) then Eclipse just complains the "Keystore was tampered with, or password was incorrect" so that route is out as well.
I'd really like to be able to test a 'real world' update before pushing the new apk to GP. Is there anyway to do this?
Export the apk signed with your release key and use adb install -r myapp.apk to update it on a device that has the older version installed.
I would like to know about Android application signing.
IFAIK, blackberry and iphone application must be signed to work on the real device.
For the Android, does application need to sign ?
If so, how to sign the application ?
Please advice. guys.
Thanks in advance.
If you are using the Eclipse plugin.
Right click on the project > Android Tools > Export Signed Application Package
Follow the instructions for creating a .keystore file and you're sorted!
There's a guide to signing Android applications on the developer website: http://developer.android.com/guide/publishing/app-signing.html
To answer your immediate concern: you don't need a real device to sign an application. You sign during the build process, so it can be done on any computer with the correct software (which is all free). The easiest way to build a signed application is to just use Eclipse's ADT plugin, which has an "export signed application" feature.
As #Laurence Dawson mentioned one way to do this is just by opening your project in eclipse then
Right click on the project > Android Tools > Export Signed Application Package
BUT you MUST create a Keystore prior to do this, this is really easy and simple the option will appear after you select "Export Signed Application Package" from right click options, it will ask you to "sign" your APK (in order to Beta/Alpha/Production publish) this process is done simply by creating this Keystore, once its created just select this new keystore (it will appear right in the options of "Export Signed Application Package") and voila! then it will just ask you for enter the path where to upload your signed APK ready for google developer website!
