(solved) How do you "getMemoryInfo(MemoryInfo)" in Delphi XE8?

[Al T 12]

Here's the code that works in Delphi 11, but it wont work in XE8 because "[DCC Error] Unit1.pas(210): E2003 Undeclared identifier: 'TAndroidHelper'

 

 

unit Unit1;

interface

uses
  System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants,
  System.Math,
  FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs,
  IdBaseComponent, IdThreadComponent, FMX.StdCtrls, FMX.Layouts,
  FMX.Controls.Presentation, FMX.ScrollBox, FMX.Memo, System.IOUtils,
  AndroidAPI.JNIBridge,
  Androidapi.JNI.JavaTypes,
  android.os.StatFs,
  Posix.Unistd, FMX.Memo.Types, Unit2, System.ImageList, FMX.ImgList,
  Androidapi.Log,
  Androidapi.JNI.App,
  Androidapi.JNI.GraphicsContentViewText,
  Androidapi.Helpers,
  credits, OptionsUnit;
  
{ MISC CODE IN BETWEEN }

function AndroidGetMemory: Int64;
var
  MemoryInfo: JActivityManager_MemoryInfo;
  AvailMb: Int64;
begin
  MemoryInfo:= TJActivityManager_MemoryInfo.JavaClass.init;
  TJActivityManager.Wrap((TAndroidHelper.Context.getSystemService(
    TJContext.JavaClass.ACTIVITY_SERVICE) as ILocalObject).GetObjectID)
    .getMemoryInfo(MemoryInfo);
  AvailMb := MemoryInfo.availMem;
  result := AvailMb;
end;

I found the problem in the code above and changed it to this:

uses
  Androidapi.Helpers,
  Androidapi.JNIBridge,
  Androidapi.JNI.GraphicsContentViewText,
  Androidapi.JNI.App;




function AndroidGetMemory: Int64;
var
  MemoryInfo: JActivityManager_MemoryInfo;
//  TotalMb: Int64;
  AvailMb: Int64;
begin
  MemoryInfo:= TJActivityManager_MemoryInfo.JavaClass.init;

  TJActivityManager.Wrap((SharedActivityContext.getSystemService(
    TJContext.JavaClass.ACTIVITY_SERVICE) as ILocalObject).GetObjectID)
    .getMemoryInfo(MemoryInfo);
  //TotalMb:= MemoryInfo.totalMem shr 20;
  //AvailMb:= MemoryInfo.availMem shr 20; in MB
  AvailMb:= MemoryInfo.availMem;
  result := AvailMb;
end;

SharedActivityContext was deprecated in Delphi 11 and uses TAndroidHelper.Context
