Changing Package Names


AppyBuilder GOLD now allows you to change application package name, even for apps with multiple screens.

WHEN changing package names AND IF you have multiple screens,you need to fully qualify screen names as shown below:

Let’s assume your email is and your app name is textingapp. Also, let’s assume, you change ApplicationPackage to appinventor.aijdoe_01.textingapp

To “Open another screen” Screen2 => "Open another screen"jdoe_01.textingapp.Screen2 - IF your email includes a dot, replace it with underscore; e.g. jdoe.01 -> jdoe_01

Notice that you’ll need to change the dot (.) with underscore ( _ ) in the email

Select “Screen1”

Type your package name in the “ApplicationPackage” textbox

If i don’t want to change package name so i leave it blank so does my package name is still like the format package like com.appybuilder.textingapp


:+1: yes.that is correct


testing your example. its not working, error 902


@fred_kowalski look at the comment in the example that i posted. Also see what @Boban_Stojmenovic posted about package names. You need to updated code to include your own email id.


a mistake. i build your apk from your aia file to see how it works in real smartphone.


I am still struggling in shifting my silver App in gold. Please go through following description and if possible point out where I am doing wrong.

  • I have an App on play store:

  • I imported this App in Gold. At Screen1, changed the package name to: appinventor.ai_takshilaonline.CTETPracticeSetsHindi

  • This App has another screen: LanguageScr

  • From Screen1, I am calling this screen as takshilaonline.CTETPracticeSetsHindi.LanguageScr

  • I also imported Keystore from Silver to Gold to settle App signing issue at Play Store.

  • Now if I upload this App to play store alpha version, it is uploaded successfully i.e. without any package name mismatch, or not signed by same key etc.

  • App also work properly with Gold Emulator, of course that time I call second screen as LanguageScr only.

  • However if I use APK file in Mobile, it is not installed. It gives error. Screenshot attached. I am unable to figure out what is wrong.

  • Help from community members is much needed oxygen.


#17 Thanks for nice explanation. Your steps seems to be correct. Your screenshot only shows the screen and no error. What is the error? Is your new app published in play store?


I have tried the steps using Keka to open my aia file on a mac. I can not seem to get it to work. I really need to move this one app over to gold.

Every time I open the aia with Keka, it creates a zip file. I do not know if that is supposed to happen, and I do not know how to drill down into it.


@PavementPilot I’m not sure about Mac. Do you have Windows box? If not, if you want, try PM me .aia and we’ll see if we can make proper-updates for you


@PavementPilot I sent you back (PM), the updated .aia. It should work now :slight_smile:
