模拟器不会在Mac上显示

Question

i am having a very similar problem like here . the difference is that i am using a mac (version 10.6.8) to which i am completely new. that's why i don't know how to handle such issues. In addition to the problem defined in that link my graphical layout also won't show up. i'm guessing, though they both are related.

so on the eclipse console it says this , wenn i try to run my app:

    [2014-07-01 02:32:38 - propra-fotoapp] Android Launch!
    [2014-07-01 02:32:38 - propra-fotoapp] adb is running normally.
    [2014-07-01 02:32:38 - propra-fotoapp] No activity specified! Getting the launcher 
                                           activity.
    [2014-07-01 02:32:38 - propra-fotoapp] Performing com.example.propra_fotoapp.
                                           MainActivity activity launch
    [2014-07-01 02:32:38 - propra-fotoapp] Automatic Target Mode: launching new emulator 
                                           with compatible AVD 'big_phone'
    [2014-07-01 02:32:38 - propra-fotoapp] Launching a new emulator with Virtual Device 
                                           'big_phone'

And regarding my graphical layout, when i click it there is an error message there instead of my layout and it says

The project target (Android L (Preview)) was not properly loaded.

I've read about many possible solutions like the one with the graphic card, restarting the mac, reinstalling eclipse or killing the adb.exe etc etc. but somehow none of them seem to work for me or don't apply in my case. any ideas?

Answer 1

Hopefully this is your problem, I had the same problem and messed around till I got my program to work. In the Graphical Layout on eclipse there is a green android icon with presumably by the error displayed, 20 written next to it. Change it to another number such as 19, representing API 19 and it will save your problem.

In the picture, the android icon I spoke about is in the top right of the picture.
