ML Kit Text Recognition Extension

[apsw171118]

@Kumaraswamy

An extension that enables the use of ML Kit Text Recognition v2 API for offline text recognition.

I see that you use the ML Kit by Google, does it support other languages?

No.

@Kumaraswamy

Only Latin format is currently being supported by the extension.

But when I tested same app in my android 10 phone it is not working when recognition text from camera. But it can recognise text from file picker

Can you please help me

[Alexandre_Gorine]

Hi Kumaraswamy,
It seems this extension is not working with SDK34.
The project was working fine when compiled with SDK33. Now APK is crashing when compiled with SDK 34. Removing this extension from the project solved the problem.
Could you please check the extension with SDK34?
Thanks

@Alexandre_Gorine

Now APK is crashing when compiled with SDK 34

post a logcat output to help @Kumaraswamy to see what exactly caused the error

Capturing Device Logs using adb logcat

ADB is a command-line utility that that can be used to control your device over USB from a computer. It will allow you to install / uninstall and or view logs on your device. This could be very handy when there are issues with a specific app and you like to view the logs for information that may lead to identify the cause of error. In this post, we’ll discuss how to install and use ADB. Installation: ADB comes with Android SDK. However, you can download ONLY the ADB files from HERE . Download…

Writable dex file is not allowed?

Problems encountered when developing apps with Android 14

[Jonas_Shen]

The same happened to me. Companion works, apk doesn't. Tested on two different Android devices with most recent Android version.

[Kumaraswamy]

Hi, I will update the extension in the coming days.

[Obiettivo_A]

Hi, did you manage to update your wonderful extension?

[Kumaraswamy]

Hello, not yet, I'm slowly clearing all the backlogs I have and with other extensions, it may take a little bit more time.

Hi! I use the extension in Kodular. Unfortunately, the extension causes the app to crash the first 2 times after installation, then everything proceeds normally. I don't know the reason. No problem with App Inventor?

use logcat to find out what's going on

@Kumaraswamy

Complain to Kodular, I cannot do anything about it, nor I have intended this extension for other platforms except AppInventor itself.
