Am getting a problem after building an android apk ,when scanning it brings me a notification that"No activity found to handle Intent {act=android .intent,action.VIEW dat=http://ai2.appinventor.mitedu/...}

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.

Please also provide a screenshot of the error message.

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.

Here are the relevant blocks,what i need is to create a report list which will be displayed to a next screen in a list viewer,showing the date name and the text present or absent,depending on the button clicked .

That's an error because there is no appropriately set browser or an application to handle the action.

This normally does not happen, are there any browsers present in your phone?

Sorry what kind of browser shall I have??

And we obviously haven't seen all the relevant blocks, in fact none at all, at least not the one or the ones that are causing or triggering the problem.

(The ActivityStarter component was probably used.)

Yeah but from what the OP has said he has trouble downloading the generated APK file. The companion app is trying to launch an activity (a browser) that could download the APK file, but it fails. Since there is no activity to handle it.

Companion app dosent directly use ActivityStarter, it uses an invisible component present in AI2. PhoneStatus Component

Blocks from the actual companion app:

That screen switch to Screen 4 is unusually elaborate.

Also, I have not seen any evidence that the two TinyDBs have different Namespaces.
