Android Question An Error Occurred

What did you uninstall ?
Check the four foulders in the window if these are still correct.

I said in my posting that I have already checked that all the paths exists.

This would be an easier fix if I knew what B4A was looking for in it's message.

I can start the AVD Manager and SDK Manager (it did some updates itself just fine)

I can (using a cmd prompt) run the Jacac.exe and the android.jar file is there

Would like to debug this before I just reinstall everything so we at least know what B4A is looking for and what got broke.

OK - I have a little more info

When I just do a Test Compile the program compiles fine.

When I do a compile & run (background) I get the error message
When I do a compile & run I get the compile dialog box which I now see is telling I have a ZipAlign file error.

OK now at least I know what to fix

Have a look here.

As soon as I knew what it was I knew how to fix it (had already read all the posts).

I just about always do a Alt-3 to compile and run so I was never seeing the message.

Sorry
