 **Note:** each example provided by the engine builds as an executable with non-cross builds and with target of a name called *"a_target"*, in following example above it would be *"android_sample"*. When building cross-compile for android **to produce the APK file you need to add *"_apk"* postfix to the "*a_target"***, because "*a_target*" gets built then as a library.
 
+#### Chrome Book SDK version
+
+In order for the chromebook to work with the apk you build you need to install the right SDK version. Go to *Tools -> SDK Manager ->System and Settings -> Android SDK* then Select the *SDK Platforms* tab and tick the "Show Packake Details" checkbox in the bottom-right corner. After that select *Android 9.0 (Pie) -> Android SDK Platform 28* and hit "OK".

 #### Chrome Book upload
 
 To upload generated *.apk* into your ChromeBook you need first to make sure your device is in *developer mode* state. If it is, you can open Android Studio and choose Debug or Profile choosing *.apk* file. Then you will need to connect to your device using **adb** connector. To make use of adb, you need to find path to the executable that is placed in `C:/Users/<your_user>/AppData/Local/AndroidSdk/platform-tools` directory. When found, you can type in Android Studio command line `C:/Users/<your_user>/AppData/Local/AndroidSdk/platform-tools/adb connect <IP of ChromeBook network>`. You can find ChromeBook's IP by entering network settings and choosing current network ChromeBook is connected to. This way the ChromeBook should be listed in available devices and you should be able to upload *.apk* to the machine through debugging app shortcut. Take into account that you won't probably be able to debug in that scenario, but you will be able to upload *.apk* to the device.
 
 #### Chrome Book debug
 
-Unfortunately debbuging android apps works 3 times out of a 100 for unknown reasons, contributions would be welcome.
+To debug the *.apk* on your chromebook you need to open the source file you want to debug in Android Studio (Either via *File->Open* or Drag&Drop, but be aware that d&d can deadlock your Android Studio 25% of the time so youll need to restart it), then place your breakpoints and hit "Debug" (The bug icon)  in the top right corner.
