How to hide Android status bar in native game written with gomobile

Question

How to hide Android status bar in native game written with gomobile?

I am experimenting with a simple native Android game written in pure Go using the gomobile tool. It should be able to use the full screen for rendering frames. However I could not find an API to hide the status bar from the native app.

Has anyone tackled this issue? If so, please share the directions.

find the solution in android side, and call from native with gomobile RPC — Jiang YD, Aug 11 '17 at 04:07
@JiangYD RPC would call a method of a server. What server would one call from the native Android game? — Everton, Aug 11 '17 at 21:40
not strict, the inter-operation between go and java is a kind of RPC. — Jiang YD, Aug 14 '17 at 02:56
@JiangYD Can you point how a pure Go Android app would call a method from an Android lib written in Java? — Everton, Aug 15 '17 at 21:46
@JiangYD No, it doesn't. gomobile doc only shows how to call a Go lib from a Java app. However it does not show how to call a Java lib from a native Go app. — Everton, Aug 16 '17 at 14:37
"Gobind generates language bindings that make it possible to call Go functions from Java and Objective-C." — Everton, Aug 17 '17 at 04:19

Create a Empty Activity . Go and find

android:theme="" on Activity XML Files

Set it to @style/Theme.AppCompat.NoActionBar

Pro Tip :

dont know other people but I always delete
Menu/Menu_Activity.Xml 
That Contains Menu XML files !

Also Remove Menu.OnClick Codes Located on The Class of Your Activity

Update :

Emm ... did you change :

public class Setup extends ActionBarActivity {

to

public class Setup extends Activity {

???

Does this make sense for a gomobile native app? I think gomobile works only with GoNativeActivity activity. Look at this example: https://github.com/golang/mobile/blob/master/example/network/AndroidManifest.xml – Everton Aug 21 '17 at 13:35
As far as I know, the gomobile app does use Java files. Where in the gomobile project is one supposed to edit the Java class? – Everton Aug 28 '17 at 18:32

On the manifest add: theme: Theme.AppCompat.NoActionBar

For each activity page in which you dont want to show the status bar

I think gomobile requires GoNativeActivity: However it reports: gomobile: apk: Create(classes.dex): spec by name not found: "@style/Theme.AppCompat.NoActionBar" – Everton Aug 14 '17 at 13:29
Ohh ok ok, that makes sense. I am not quite familiar with gomobile – Yunus Kulyyev Aug 15 '17 at 01:42

This is how to disable the Android status bar in a native application written with gomobile:

Add this exact theme to AndroidManifest.xml:
