    "Not pretty" is not problem if it will work :)

    Thanks :)

    Well, for now you can do half the job easily enough. That snippet for launching it you should be able to get working by appropriate fiddling with these snippets:

    procedure LaunchURL(const URL: string);
    var
      Intent: JIntent;
    begin
      Intent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_VIEW,
        TJnet_Uri.JavaClass.parse(StringToJString(URL)));
      SharedActivity.startActivity(Intent);
    end;

    procedure ShowBatteryUsage;
    var
      Intent: JIntent;
      ResolveInfo: JResolveInfo;
    begin
      Intent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_POWER_USAGE_SUMMARY);
      ResolveInfo := SharedActivity.getPackageManager.resolveActivity(Intent, 0);
      if ResolveInfo = nil then
        ShowMessage('Cannot display battery usage')
      else
        SharedActivity.startActivity(Intent);
    end;

    Likely units required will be these: FMX.Helpers.Android,
      Androidapi.JNI.JavaTypes,
      Androidapi.JNI.GraphicsContentViewText,
      Androidapi.JNI.Net

    Alas the onActivityResult side of things will have to wait a bit until I can document what I've done in my current project (which requires custom command-line build script to re-build the Android package).

    "Not pretty" is one thing, but it's also a tad involved, thanks to the lack of catering for this (yet).

    Well done Brian Long, resolveactivity is a good find!
