I ran the App Inventor Setup installer on Windows, but the phone device drivers do not install. There are multiple reasons for this, and we're trying to track them all down. The Windows driver installation instructions in the App Inventor documentation contain our best advice, and we'll keep those current as we get more information from users.

Note that the drivers included in the App Inventor Setup software do not work on all Android devices, and you may need to get drivers from the manufacturers. See the Windows driver installation instructions for advice, and check the App Inventor Forum to see if others have had similar issues with the version of Windows and the particular device you are using.

Try the following steps to troubleshoot your wireless connection. If you have a "telnet" program, you can attempt to telnet from the computer to the phone on these ports. If the connection won't complete, then there is likely a firewall in place that is blocking connections to the phone. If you attempt to use an older version of the Companion App with App Inventor, you will be prompted to update it. If you have trouble connecting using these wireless instructions, make sure your phone is using WiFi and not the cell network.

On some devices and in some locations, even with WiFi enabled, the phone continues to use the cell network for Internet connectivity.

If this is happening to you, you can disable mobile networking cell phone carrier based Internet connectivity from your device's Android settings menu.

The phone or emulator shows a notice -- Security error receiving blocks from browser. The browser may have loaded a new project without the Companion recognizing that. Perhaps the phone was unplugged? Reset the Companion by using the menu key on the emulator and select "stop this application.

App Inventor doesn't yet include any way to store files on the SD card. It also doesn't yet include a way to list the files on the SDCard.

You'll have to use other applications or the Android phone file manager for that. Using the SD Card provides a lot more space for media than trying to package things as assets. The drawback is that users won't automatically get them by installing your application. Make sure you use the link that points to the actual file, not to players for the files, which is much more common on the Web, especially for music and videos. Your attached file contains too much redundant code. I've optimized your code.

The save feature will be added at a later date ". To exit the application, press either the back key once again or press the Exit button on the main screen once again. Note that this application will save the generated passwords. ShowMessageDialog has been replaced with Notifier. ShowChooseDialog - This lets the users to choose if they want to exit or not.
