Android Question How to call "setStatusBarColor" with Reflection

[cb56]

Please can you help me in calling "setStatusBarColor" to change status bar color with api 21 (Lollipop)?

http://developer.android.com/reference/android/view/Window.html#setStatusBarColor(int)

I need a code example.

Thanks

This code calls this API:

Dim jo As JavaObject
jo.InitializeContext
jo.RunMethodJO("getWindow", Null).RunMethod("setStatusBarColor", Array(Colors.Red))

It didn't do anything when I test it.

The flow is more than just that.
first it get getIdentifier("config_enableTranslucentDecor", "bool"
then it
get the bool to know whether the statusbar and navbar are translucent

                int[] attrs = {android.R.attr.windowTranslucentStatus, android.R.attr.windowTranslucentNavigation};
                app.Log("?X3?");
                TypedArray a = app.context.obtainStyledAttributes(attrs);
                app.Log("?X4?"+a);
                try{
                    mStatusBarAvailable = a.getBoolean(0, false);
                    mNavBarAvailable = a.getBoolean(1, false);
                } finally {
                    a.recycle();
                }

and

                WindowManager.LayoutParams winParams = win.getAttributes();
                // check window flags
                int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
                if ((winParams.flags & bits) != 0) {
                    mStatusBarAvailable = true;
                }
                bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION;
                if ((winParams.flags & bits) != 0) {
                    mNavBarAvailable = true;
                }

and in last step it adds a view to the viewgroup

  private void setupStatusBarView(Context context, ViewGroup decorViewGroup) {
      mStatusBarTintView = new View(context);
      LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, mConfig.getStatusBarHeight());
      params.gravity = Gravity.TOP;
      if (mNavBarAvailable && !mConfig.isNavigationAtBottom()) {
          params.rightMargin = mConfig.getNavigationBarWidth();
      }
      mStatusBarTintView.setLayoutParams(params);
      mStatusBarTintView.setBackgroundColor(DEFAULT_TINT_COLOR);
      mStatusBarTintView.setVisibility(View.GONE);
      decorViewGroup.addView(mStatusBarTintView);
  }

All this are NOT WORKING code-snippets from a librarywrapper whih does not work... I always stuck in the last point....

But yesterday i got the MaskedImageView running... Maybe it helps here too what i did to get it work yesterday. The issue is similar...

It works with Material Theme.
