General Tips and Tricks for App Inventor

This list was made by @Taifun Use different screens wisely Before starting to create another screen, first you should think about is it really necessary? See also Building apps with many screens and SteveJG's post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed... If you decided to use different screens, then you should switch them correctly, else you …

Download the file to some directory, then read the file on the other screen. Put it in the "APP" storage is what I reccomend.

@Yogesh

can you help

store the path of the taken image in TinyDB
read that path in the other screen and display it in an image component

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
How to do a lot of basic things with App Inventor are described here: How do you...? .

Also do the tutorials Our Tutorials! to learn the basics of App Inventor, then try something and follow the Top 5 Tips: How to learn App Inventor

Thanks it worked. Now I want to try showing more images how should I do that?
I tried using if else then got stuck on defining image1 = null. Like if null then show image if not then show it to image2.

[Taifun]

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

Base64 Tools - five little ones ;)

Update Now added a fifth "little one", Base64Convertor. This will convert a binary file to a base64 string, and convert a suitable base64 string to a binary file. You will have to set absolute paths (possibly full paths in some circumstances) to the files... You can download this extension from the first post in this topic.

[Yogesh]

it doesn't contain any other extension you have
