Emulator Starting Problem

[Hassan Raza]

Hello all, I am using App Inventor 2 from last last couple of weeks. 

I started with a famous "Hello World!" App and successfully run it on EMULATOR. 

But after couple of days later when I try to run it again onto EMULATOR. It started giving me ERRORs. 

Kindly help me get rid off from this problem.
THANKS

REGARDS.

Some snaps are also attached.

Do you like to leave your PC running overnight?

Maybe it has extra copies of adb.exe running, blocking the connection to the emulator.

Kill them all from Windows Task Manager

then RESET Connection from the AI2 window.

Hi Hassan,

Can you run the following test for me and show the output?

Press Windows+R to bring up the run command dialog.

Type cmd.exe and press enter.

In the command prompt that opens:

1. Type "C:\Program Files (x86)\AppInventor\commands-for-Appinventor\adb.exe" devices (including quotes) and press enter
2. Type "C:\Program Files\AppInventor\commands-for-Appinventor\adb.exe" devices (including quotes) and press enter

If everything is okay, one of these two should return something like:

C:\Users\ewpatton> "C:\Program Files (x86)\AppInventor\commands-for-Appinventor\adb.exe" devices"

List of devices attached

emulator-5554    emulator

Note that the last line won't be present if you don't actually have the emulator up, but that is not important for this first test. If both of these commands come back with errors, did you change the installation directory or install under a different, non-administrator user?

HI EVAN,

I run commands in cmd as you instruct me and following output appear which I think shouldn't appear.

Here is scree shots

Thanks Hassan.

You forgot to include the keyword devices at the end of the command, but the output confirms that adb.exe is there and that you have permission to run it; that's good. I'm curious now if the following runs, and if not, what the error message is:

"C:\Program Files (x86)"\AppInventor\commands-for-Appinventor\adb devices

Would you mind running that command? This is the same command as what aiStarter runs when the echeck is performed.

Hi EVAN,

I Run another command in CMD as you instruct and following output I get.

Look at this and tell me something
