Hello Cocuelle,

Check your platform to make sure you're not trying to run against Android Wear, which is 4.4W. Also, make sure you're running lower than API 20, as 20 is the L Preview.

I would try running with API 19, Platform 4.4.2.

I hope this helps.

Hello,

I've heard a few users struggle with this actually.

I previously did a bit of research on this and believe that the SDK version is to fault. What you've probably done is used the SDK for Smartwatches (The Android Wear SDK).

In your build.gradle file (I think it's found in the android folder), use the following code:

android {
    compileSdkVersion lpreview ? "android-L" : 19
    buildToolsVersion "19.1.0"

    productFlavors { lpreview ? lpreview{} : classic{} }

    defaultConfig lpreview ? {} : {
        // Non-L-preview configuration
        minSdkVersion 14
        targetSdkVersion 19
    }

The issue is that you used Android 4.4W (It's easy to do: http://gyazo.com/1f582d03bd1afd18c377100beb209d00) which is the Android Wear SDK however, that's also API 20 right now!

Yeah. The fun of Android! Anyhow, you shouldn't have this issue when Android L is officially released but, this fix will work for now. It should allow you to choose between 4.4.2 and Android L.

Thanks you so much for the fast answer, and by checking now i realise i did a stupid mistake grabbing the 4.4.W instead of 4.4.2 while downloading !
