nice explanation. i am not getting. aia file maam. can you please share the link? i m successful in adding records.just unable to view in listview on screen initialize event.
Please see the advanced tutorial for this app in which I have shown this error handling and also duplicate user name check to avoid a second user using the same user name. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Cmy0VueB1zc.htmlsi=vu0zRKZMdVAp1Ter
Mam I really liked the video. I want to know if we can use the CloudDB Data in listpicker so that the list picker gets updated whenever we update the data Please guide
Thank you for liking the video. Yes, you can use CloudDB data to provide data to your list picker. Store the data as a list against a tag in CloudDB. Load the data when the screen is initialized using the getValue procedure of CloudDB. In the gotValue event of CloudDB, set the list picker's elements to the value returned by CloudDB. In the Data Changed event of CloudDB, set the list picker's elements to the value returned by CloudDB. Just remember: If you use the default CloudDB provided by MIT App inventor, then the app adding data to the CloudDB and the one with the listpicker will have to be the same. If you are using the free Redis Cloud as shown in this tutorial then you can have two different apps: one for adding the data for the list picker to Cloud DB and the second app can be the one with the list picker. With free Redis Cloud, you can also add data through console.
Most welcome 😊 My next tutorial will be on a similar topic. Image picker to firebasedb but you can use clouddb instead as the blocks are identical for both types of databases in MIT App Inventor.
Since I've been here for a long time.. May i ask another question. How do i convert the questions into a photo. Like the photo is the question. Using database . Thanks you help me a lot.
Have a look at this video to see how you can store and load images from database. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cZISCpMvaG0.htmlsi=8IgOvOZuXRKcejGl this is in the case if your images have been taken by camera. If you want to use preexisting images as questions, you will have to encode and save to database in a different way. I haven't done a tutorial on this yet but this tutorial might help you: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-U-tlpOdMGUs.htmlsi=sKAj1E4fxqhyo3Nt I am uploading to google drive but you will have to change it to upload to database.

can you help me fix this error : Error: Unable to export or encrypt the private key java.security.NoSuchAlgorithmException: Cannot find any provider supporting RSA/NONE/OAEPWithSHA1AndMGF1Padding at java.base/javax.crypto.Cipher.getInstance(Cipher.java:574) at com.google.wireless.android.vending.developer.signing.tools.extern.export.ExportEncryptedPrivateKeyTool.encryptPrivateKeyWithCkmRsaAesKeyWrapEncryption(ExportEncryptedPrivateKeyTool.java:284)
And also .zshrc export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-20.0.1.jdk/Contents/Home export PATH=$JAVA_HOME/bin:$PATH after typing this - when i enter command + D - nothing happening
Please check that you are looking at the correct sheet named form responses 1. You can also verify your code by looking at the written tutorial: obsidiansofteducation.blogspot.com/p/send-data-to-google-sheet-from-mit-app.html
This is the make quiz tutorial in which we add questions and answers in database ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-J4ksXNTlq3g.htmlsi=uMbQkNhARLsOtTDk
You need to use the Redis cloud DB as explained in the tutorial, too ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-J4ksXNTlq3g.htmlsi=oEYpUQMto8uL2eAt You might have noticed that i am not using the MIT app inventor deafult cloud dB component in these two apps as the default CloudDB can not be accessed by two different apps. You can also use Firebasedb. I have done a tutorial on setting up firebasedb, too.
Kindly tell me what is exactly not working? Which button? So that I am able to suggest a solution. Also, is the basic version from the previous video working?
Whenever I try to connect my pc to phone to play on the smaller device, I always gets a notification saying "Error from Companion: error: unrecognized method. (irritants: setMarkOrigin)" and I'm not sure how to fix it
These are the 3 global variables that you create yourself when you come to the blocks section after designing the screen. We have 3 global variables: firstNumber, secondNumber and operator. I have shown the making of them here 09:10
You mean in the video or MIT app inventor? If you mean video, then this is a two parts tutorial, so watch the second part to complete the calculator app. If you mean all the components are not showing in MIT app inventor then go to project settings and choose "expert" toolkit.
