How to make Delphi Android app run in the background and then be maximized without being restarted?

I have an Android app written in Delphi.

When launching the app and initializing another app by Intent, after closing the second app and going back to the first app, the first app is restarted.

Note: I saw that there is something about the onSaveState event, but I need my app not to restart because I use the return data from the second app in it.

I performed the initialization of the second app by Intent and when closing the second app, it should go back to the first one at a point where I can manipulate the Intent information where I opened the second app, but it is restarting the first app.

UPDATE:
--//--//--//--//--//--//
Here is my code:

procedure TForm1.btnEnviarTransacaoClick(Sender: TObject);
begin
   try
      var AURI:string:= 'payment-app://pay?return_scheme=retorno&amount=9999&editable_amount=0&transaction_type=credit';
      var AIntent: JIntent := TJIntent.Create;
      AIntent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_VIEW);
      AIntent.addFlags(TJIntent.JavaClass.FLAG_ACTIVITY_NEW_TASK);
      AIntent.setData(TJNet_Uri.JavaClass.parse(StringToJString(TIdURI.URLEncode(AURI))));
      TAndroidHelper.Activity.startActivityForResult(AIntent, 0);
      Timer1.Enabled:= True;
   except
      on E: Exception do begin
         TThread.Synchronize(nil, procedure
         begin
            lOG.D(E.Message);
         end);
      end;
   end;
end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
   Timer1.Enabled:= False;
   var ADLg:= TForm2.Create(Self);
   ADLg.Show;
end;

note: after start activity , I trigger a 4 second timer to create a new form and show it, but after finishing the second app and returning to the home app, the home app restarts. Sometimes debugging I managed to catch the exception:

> cant perform this action after onSaveInstanceState

this is my AndroidManifest, where to use explicit intent by scheme

{<activity
				android:name=".PaymentActivity"
				android:launchMode="singleTop"
				android:exported="true">
			<intent-filter>
				<action android:name="android.intent.action.VIEW" />
				<category android:name="android.intent.category.DEFAULT" />
				<category android:name="android.intent.category.BROWSABLE" />
				<data
					android:host="pay-response"
					android:scheme="retorno" />
			</intent-filter>
		</activity>}

我找到了问题：

在我的 AndroidManifest 中，主活动使用了 launchmode: SingleTask，只需将其更改为 singletop 就解决了问题。

I found the problem:

in my AndroidManifest, the main activity was using launchmode: SingleTask, just change it to singletop that solved the problem.
