You should totally add on a screen recorder block that allows you to record what is happening in the app, and while you're playing it. I would like it because that would make making videos for class and youtube on it much easier.
For the purpose you describe, the screen recorder would not normally be part of the App you wish to record. It would instead be a services App, run at the same time to record your App. Most Smartphones already have this built-in, but you can also use one of many available on Google Play Store.
You wouldn't be adding a recorder to all your Apps though, better to use the phone's recorder or a 3rd party services app. Screen recording can be a burden, requires memory for recording and storage at high speed.
Yes, it can.
Once you grant the Screen Capture permission, you are sharing your screen which is converted into bitmap and gets recorded.
This process will continue as long as your app is running.
@vknow360 How do you install the extensions for app inventor? And which extension is yours? @ABG I'm going to try to install Memu on my Andriod Zen UI pad. I'll tell you if I like it.
