Set it to a correct filename, for example myFilename.3gp

Specifies the path to the file where the recording should be stored. If this property is the empty string, then starting a recording will create a file in an appropriate location. If the property is not the empty string, it should specify a complete path to a file in an existing directory, including a file name with the extension .3gp.

Yes, his project (aia) is broken.

The Speech Recogniser Component and Block IDs are prefixed with "AE" and that causes the no-load issue. When attempting to load, AI2 very briefly displays a message to that effect.

So perhaps there is an extension in the mix?
The only permission requested in the Blocks: WRITE_EXTERNAL_STORAGE.

However, as per Taifun's note, the file to write must have a name and .amr is not an acceptable file type for recording using the App Inventor Sound Recorder.

... which is not required because the Sound_Recorder component automatically requests this permission.



Oops! That page doesn’t exist or is private.

The page can't be read.

Yes sorry, it was a post from the power user forum:

What happened?
The permission WRITE_EXTERNAL_STORAGE is granted.
Save format: 3gp
Platform: AI Inventor (private)

What about Record Audio permission?

Show your blocks and read this first:

Yes enabled

Tried a few times and isn't responding after holding the button (which starts the recording)
