Taifun Camera Extension?

[Marsman_Gmail]

Hello everyone! Have a nice day ahead

I am currently developing an android app that will be able to take a picture and set the file name of the image right after taking a picture. I have heard about this amazing extension which is called as Camera Extension by Taifun. I am planning to buy this extension, I just want to make sure if this extension is applicable to the app that I am currently developing. Hoping for your kind response, thank you.

This will depend on how much control you want over the camera. Explain in more detail how you want your app to work.

Hello @TIMAI2 ,

The user of the app will take a picture of a particular place. Now, after taking a picture, the user will set manually the file name of the image right after the picture was taken so that the user will be able to recognize where the picture was taken through the file name of the image.

[TIMAI2]

If the user is taking the picture, then you can program all you want to using existing built-in components.

you can use taifun file extension
i created an example and works

[TIMAI2]

Your example will not work for Android 10+. It may work if you set the filescope to Legacy.

I tested this in android 8,11 and worked

filescope=legacy

You are not allowed to copy or move files to arbitrary directories anymore... use shared storage like /Download etc... see also here

How to access non-media & media files on Android 11+

Access to non-media files on Android 11+ On Android 11+, non-media files (like txt, pdf, csv, ...) can be accessed if and only if the text files are in the → ASD or in the → Private dir (i.e. were saved there), or the text files are in one of the Shared folders /Documents or /Download and these files were created by the app itself, or SAF is used, or MANAGE_EXTERNAL_STORAGE* permission is requested and granted. *` This is not really an option, because an app that requests this permi…

EDIT @Marsman_Gmail for your purposes you do not need any extensions... just use the camera and file components

Well Done, Taifun

@Alireza_Sharifi you might want to add, that your solution only works, if you do not plan to upload the app to Google Play because of the manage external storage permission... just remove the activity starter part... also asking only for WRITE_EXTERNAL_STORAGE permission would be sufficient...and set DefaultFileScope in Screen1 to Legacy...

I have forgotten this. I found this in my aix files

I never upload my projects into play store

How to request and grant MANAGE_EXTERNAL_STORAGE permission

In this guide I show you, how to request and grant → MANAGE_EXTERNAL_STORAGE on devices with Android 11+. Be aware that this permission is usually not granted by Google. However, let’s assume the app is only intended for private use or for special users or for other app stores. This permission must be declared in the Manifest (since it is not declared the Companion app you can't test this with Companion): <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"/> Here is a s…

after taking a picture, the user will set manually the file name of the image right after the picture was taken so that the user will be able to recognize where the picture was taken through the file name of the image

This is all you need:
cameraNamePic.aia (39.1 KB)

Storage permissions are not required on Android 11+ if you use the TaifunFile extension instead of the File component, so I would prefer this solution as I always try to avoid permissions whenever possible.

(There is no need to set DefaultFileScope = Legacy as the TaifunFile extension declares storage permissions in the correct way.)

Hello @Anke ,

I tried the AIA file you sent to me, and it worked. I have also tried it in Kodular, but it gave me an error message saying, "Error 201: Camera did not return an image". Does it work for App Inventor only?

@Marsman_Gmail

"Error 201: Camera did not return an image". Does it work for App Inventor only?

In Kodular there is a bug with the Camera component.
I have already reported about this bug there and also about the countless other bugs (since the last update).

My solution/approach should also work on Niotron and other AI2 distros that are actually based on AI2.

I will not comment further on Kodular (for very good reasons).
As a general rule, if you have questions about Kodular, ONLY ask them there.

Oh, I see... Thank you for the information @Anke and to others who shared their knowledge to me, I am now enlightened about the app I am currently developing. God bless you all.
