So today, while writing an example for the JCG community, I came across the following exception, while trying to add an 
EditText element to my application:
Exception raised during rendering: java.lang.System.arraycopy([CI[CII)V
Despite the fact that I selected Android 4.4 (API 19) for my application, I noticed that the selected Android API in the Graphical Layout of my XML code was actually wrong:
So, the easy way, I clicked the dropdown to select again my initial option:
Note: the Wear versions don’t support EditText elements and that’s why we got the exception.
And of course, everything was fine after that:
Cheers!

Wow, that was easy…
Was struggeling a while whith this now!
Do you know why the API20: Android L is not selectable, although it is installed in the SDK Manager?
Or is it included in the 4.4W API?

Ok, I forgot to include System Images in the SDK Manager.
Now the API 20: Android L is also available and it works fine.

Hi Christian, thank you for your comment!
As you probably know, too, Android L will be officially “launched” at late 2014, so till then, it 'll be in a pilot mode.
Nevertheless, we are actually able to develop “L” apps, under some guidelines.
To ensure that everything is set properly for “L development”, try following the official guide: http://developer.android.com/preview/setup-sdk.html
As you probably noticed, there is also a special reference for System Images, under the “Set Up Hardware and AVDs” paragraph.

Wow. These errors sometimes look ominous as F**K, like I'll never be able to figure it out, and my project is doomed. Yet, they end up being so simple it's STUPID…

Thanks for the information!
Though I tried out the new API with my project and it worked with the according Emulators, clearly not with ones below L…
Now I changed back my project to API 19 (project structure + graphical layout API)
It looks good in the Android Studio design preview, but when I start the emulator (for API 19) it rearranges my controls and it doesn't really fit on the screen (same problem on the phone itself)
did I f*** up my layout with temporary switching to L?
I can't see the problem when developing, because the layout looks fine in the Preview…
You must know in “File > Project Structure” the “Build Tool Version” is still set to “20.0.0” and doesn't allow any other values…
Do you know this kind of problem?

Hi,
@Thodoris: hope it's ok to post now and then…?
@question:
which APIs are installed in the SDK Manager and which Android Development Kit is selected under “File > Project Structure”?
Usually depending on these things you can select the API.

Hi Christian,
excuse me for the late response, but I had a lot of work during this week.
I suggest keeping the same discpline for an independent project (same versions for “Target SDK” and “Compile With” – search for “Figure 1” in this link, if you misunderstood something: http://examples.javacodegeeks.com/android/core/app/fragment/android-fragment-tabs-example/ )
This should solve your problem and if not, prefer KitKat instead of L, since L is not still so “stable”.

Hello Anonymoys!
First of all, as a disclaimer, you should read my recent reply to Christian (July 20, 2014 at 5:11 AM). Once this is done, I guess that you only downloaded the latest versions of the required for Android Developement, tools, so what you have to do, to get over this, is to download a now-wear version of Android SDK, by clicking the “Android SDK Manager” icon in your Eclipse IDE (a selection like this http://snag.gy/elK1P.jpg, should be good, regarding Android KitKat)
