Some Appery.io users who generated an .aab file with Appery.io and are trying to upload this to Google Play store as an update, may encounter this error:

Before we help you tackle this issue, here is a bit of theory behind it:

As of August 2021, there has been a significant shift in the deployment process for developers targeting the Google Play platform. The conventional .apk (Android Package) format, which has been the standard for Android applications, is no longer accepted by the Google Play store for publishing new apps. In its place, Google has mandated the use of the Android App Bundle (.aab) for all new apps, a publishing format that streamlines the app signing process for developers.

This transition to the .aab format can have direct implications if you’re attempting to update your existing Appery.io app on Google Play that was originally published using an .apk file. 

Below, we share some simple steps you can take to address the issue of updating your existing Appery.io app on Google Play:

1. Begin by downloading the certificate archive and extracting it.
2. Afterwards, navigate to the Google Play Developer Console and proceed to Release > Setup > App Signing. If necessary, agree to the Terms of Service for App Signing.
3. Choose the option Use existing app signing key from Java KeyStore, then follow the subsequent steps:

4. Obtain the PEPK tool and launch a terminal window.

5. Enter the command as follows, replacing the placeholders with your actual file paths, alias, and Google encryption key:

java -jar PATH_TO_PEPK_TOOL --keystore=PATH_TO_YOUR_KEYSTORE --alias=YOUR_ALIAS --output=PATH_TO_YOUR_OUTPUT_FILE --encryptionkey=YOUR_GOOGLE_ENCRYPTION_KEY

✋ Caution: Ensure the accuracy of the paths for the PEPK tool, keystore, output file, as well as the correct alias and Google encryption key.

For instance, if your setup has the specified names, your command might look like the following:

java -jar pepk.jar --keystore=apperyio.project --alias=apperyio.project --output=encrypted_private_key_path --encryptionkey=eb10fe8f7c7c9df715022017b00c6471f8ba8170b13049a11e6c09ffe3056a104a3bbe4ac5a955f4ba4fe93fc8cef27558a3eb9d2a529a2092761fb833b656cd48b9de6a

6. At this moment, the system will prompt you for a password. It is advisable to reuse your current keystore password. So, input the keystore password (for instance, ‘apperyio.project‘) followed by the key password (again, potentially ‘apperyio.project’).

7. With your passwords entered, you can now upload the generated App Bundle (.aab) file to Google Play by clicking Upload private key:

8. Finally, click Save.

Congratulations: your updated app is up and running!

Happy Tnanksgiving from all of us, at Appery.io!

Today we are pleased to announce the September release of appery.io with new alias $a of Appery helper, global variable $v and global functions!

Let’s look at what’s new

$a

‘$a’ is an alias for the Appery helper ‘Apperyio’. Now, instead of writing:

this.Apperyio.navigateTo("Screen1");

you can use a much shorter form:

this.$a.navigateTo("Screen1");

$v

‘$v’ is an alias for global variables that were previously accessed through Apperyio.vars.

$v is a place for storing any data as ‘global’. For example, to transfer data between screens.

this.$v.myData = 12345;
this.$v.userInfo = {id: 123, name: 'Joe'};

For more detailed information about ‘$v’, you can refer to our documentation https://docs.appery.io/docs/6-model-and-storage#apperyio-global-variable

Appery Helper

The list of functions and properties for the Appery helper ‘$a’ has been significantly expanded. This expansion greatly simplifies the invocation of the most commonly used operations. For example, if you need to display a modal window and pass parameters to it, this can now be achieved in a single line of code:

let data = await this.$a.modal("EditUser", {name: 'john'});

If you need to display a loading indicator, a simple call will do:

await this.$a.showLoading();

And if you need to perform a GET request:

let res = await this.$a.get("https://mydomain.com/user/12345");

You can explore the full list of available functions on this page: https://docs.appery.io/reference/common-methods-and-properties

Global Functions

Global functions have been added. Now, in the Functions section under Modal and Storage, you can define a function, for example ‘sum’, which will be accessible on all screens, custom components, services, etc., using this.$v.sum()

For more detailed information about global functions, you can refer to our documentation https://docs.appery.io/docs/6-model-and-storage#global-functions

We believe this new feature will be of great value to our users. We appreciate your continued use of Appery.io, and we wish you a happy developing!

Thank you for using Appery.io and Happy Developing!

We’re excited to announce the introduction of the latest Appery.io release, which includes support for Android 13 (API level 33).

While many of the Appery projects were upgraded automatically, we aimed to keep manual application changes to a minimum to ensure a smooth transition for all users.
– Please ensure that you have not manually modified the config.xml file in the source tab. If any modifications were made to this file, kindly follow these steps: Remove the file and execute the “Undo all source changes” operation for the CORDOVA folder.

– Additionally, for some users, it may be necessary to access the App Settings. From there, navigate to Cordova Config, then proceed to the Android tab. Ensure that the property “GradlePluginKotlinVersion” is present with the value “1.6.20” (refer to the provided image for visual guidance). If this property is missing, kindly add it manually.

We believe this new feature will be of great value to our users. We appreciate your continued use of Appery.io, and we wish you a happy developing!

Thank you for using Appery.io and Happy Developing!

It’s not been long since Appery.io announced releasing the revolutionary ChatGPT Template and we are super excited today to let you know that our template has been upgraded!

Several days ago, a new ChatGPT model family was released, named gpt-3.5-turbo. The model is similar to the model used in the ChatGPT product and accessed with a new endpoint for interacting with ChatGPT models.

We, at Appery.io, made this enhancement available to our users and updated the template to keep up with the latest ChatGPT model from its creator, OpenAI!

The updated ChatGPT App template works out of the box like its predecessor did before and allows the creation of a bot app based on the OpenAI ChatGPT technology that already supports the new ChatGPT Turbo model.

Please check our template to enjoy the technology even more! It’s simple to get and free to try:

1. Sign up for free (if you haven’t yet).
2. Create a new app from under the Templates tab:

3. Enter your OpenAI API Key and you are ready to test the app:

Happy developing! And stay tuned – more templates are coming soon!

We are happy to present another new template, Offline Map App, that is designed to help with creating a mobile app that will allow downloading maps with further using them offline.

The template is made simple and easy to use. To create it, you will only need to log in to your Appery.io account (if you are new to Appery.io, here is the link where you can sign up to try us for free), and create your own offline map by selecting the Offline Map App under the Templates tab:

In a moment, you are almost ready for testing the app on your device (this app is operating with a native API, so it cannot be tested in the browser):

But if you want to go further and customize it (it is actually a template and was created for customizing), here are the detailed instructions that explain how to do it.

As a result, you can end up with a unique and attractive UI that will definitely stand out from all similar apps out there:

There is another great news we are happy to share with you today: the Autoupdate plug-in has been added to all Appery.io apps and is ready to be used.

Adding this plug-in is simple and requires zero effort on your part to set it up. But when added, it just gets the job done. 

The idea behind it is as simple as it can possibly be:

• You add the plug-in to your app and publish it so that your users can install it on their devices.
• Next time you need to make changes to your app you just make them and push the app updates.
• With the next app run on the device, the plug-in automatically detects there is a new update on the server and lets the end user make decisions on whether to download it from the server and then install it on their device or postpone this action:

Autoupdate plug-in on the device

Please check out our document here to learn how to work with the Autoupdate plug-in.
