try to monitor the values that are given to "font.size", or attach a simple project where we can check

From the posted code it is not clear what values are passed, for example what is assigned to "Font.name"? You need to find out which value is not right, start disabling some lines to see if the problem disappears.

I also had the same problem, I solved it by deleting the two files "IconCache.db" and "IconCache.db.backup", then I call twice "SHChangeNotify(SHCNE_ASSOCCHANGED,SHCNF_IDLIST,Nil,Nil)"

You could use the "Tag" property to distinguish them.

Try using "Mouse.CursorPos"

You can try to postdate the association with the "OnClick" event, perhaps with a timer

have you tried using the "onMouseUp" event?

I tried it on a Samsung A13 and all the keys respond the same way, without any apparent delay (D12)

Try it this way procedure TFormMain.FormCreate(Sender: TObject); begin Image1.Parent := DrawGrid1; Image1.Left := 0; end;

Try var LCursor : JCursor := TAndroidHelper.Context.getContentResolver().query(URIfileTrn,nil,nil,nil,nil); If LCursor=Nil Then Exit; LCursor.moveToFirst; var colIndex : Integer := LCursor.getColumnIndexOrThrow(TJOpenableColumns.JavaClass.DISPLAY_NAME); If colIndex<>-1 Then Result := JStringToString(LCursor.getString(colIndex)); Except Result := ''; End; with the latest OS, with the path you get you can't do anything with it, personally I download the file in the personal folder and use it

You probably have set the "Style" preview to "Windows", try selecting the right destination (you can find it in Design)

if you change the value to "PrinterIndex" it is called "EndDoc", so you have to select the printer before "BeginDoc"

I also encountered the same problem, I solved it by replacing the code: Ad := '"' + DosyaAdi(Uri) + '" ' with If RequestCode<>Dizin_Agaci_Ac Then Ad := '"' + DosyaAdi(Uri) + '" ' Else Ad := TPath.GetFileName(JStringToString(uri.getPath)); in the "OnActivityResult" procedure, but it still doesn't work, even if you give consent you can't read the files. I tried with the "Download" folder and I only get the folders contained therein.

The problem is that if the division results in "NAN", no exception is raised, so at runtime the error cannot be detected.

Have you tested it? because it works for me, it won't be the best of programming, but if it works...

I had a similar problem with android, I solved it by trying to convert the result to string and then to number, so I modified your code a bit, but I can't test it with "NAN": procedure TForm2.Button1Click(Sender: TObject); var V1, V2, V3: Variant; I1, I2: Integer; S1 : String; begin V1 := 0; V2 := 0; Try V3 := V1 / V2; Except V3 := -1; End; Try S1 := FloatToStr(V3); StrToFloat(S1); Except V3 := -1; End; If V3=-1 Then ShowMessage('Division by zero') Else ShowMessage(V3); I1 := 0; I2 := 0; ShowMessage(FloatToStr(I1 / I2)); end;

Have you tried changing the "Scale" property? in some cases it may be fine

If your intention is to open the explorer automatically in a specific location, I don't think it's possible to do it with the system one. Third-party ones do it instead, but I've never faced the problem. This session could be a good start to understand if there is a possibility to do it.

I use this: uses Androidapi.JNI.GraphicsContentViewText, Androidapi.Helpers, System.Messaging, Androidapi.JNI.Net, Androidapi.JNI.App, PROCEDURE TForm1.GetFileBrowser; VAR Intent : JIntent; ReqCode : Integer; BEGIN ReqCode := 1000; Intent := TJIntent.Create; Intent.setType(StringToJString('*/*')); Intent.setAction(TJIntent.JavaClass.ACTION_GET_CONTENT); Intent.putExtra(TJIntent.JavaClass.EXTRA_ALLOW_MULTIPLE,true); TMessageManager.DefaultManager.SubscribeToMessage(TMessageResultNotification, procedure(const Sender : TObject; const aMessage : TMessage) VAR msgRES : TMessageResultNotification; begin msgRES:= TMessageResultNotification(aMessage); If msgRES.RequestCode=ReqCode Then if (msgRES.ResultCode=TJActivity.JavaClass.RESULT_OK) Then Begin URIfileTrn := msgRES.Value.getData(); //URI sing file selez If URIfileTrn=Nil Then //multiselez ClipDataF := msgRES.Value.getClipData; End; end); TAndroidHelper.Activity.startActivityForResult(Intent, ReqCode); END; and then via thread process the URI

you're declaring the same variable 10 times, I don't think it's possible the way you mean, you could alternatively use a record type, and then call it in an array, like: type myRec = Record myVar : String[20]; End; [...] var ArrRec : Array Of myRec; [...] procedure Sample(const AFixedArray: TSomeFixedArray); begin SetLength(ArrRec,10); for var I = 0 to 10 do begin ArrRec[I].myVar := 'xyz'+I.ToString; // do something end end

If you have the rights to access the "DCIM/MyFolder" folder, you could build a simple browser (via "System.IOUtils.TDirectory.GetFiles") yourself and display the files contained in a list. Or launch an "Intent" with "ACTION_GET_CONTENT", to open the system app

Handle it like a data store? In the sense of creating a record for the first file where some fields point to the second file, so when you order the first, to read in the second file you just need to read the pointer.

Hi all, I have a code to maximize and minimize screen brightness for android app, which works fine in 32bit, but not in 64bit. Here is the code: USES Androidapi.JNI.GraphicsContentViewText, Androidapi.Helpers; procedure TForm1.Button1Click(Sender: TObject); //min VAR appParam : JWindowManager_LayoutParams; begin appParam := TAndroidHelper.Activity.getWindow.getAttributes; appParam.screenBrightness := TJWindowManager_LayoutParams.JavaClass.BRIGHTNESS_OVERRIDE_OFF; TAndroidHelper.Activity.getWindow.setAttributes(appParam); end; procedure TForm1.Button2Click(Sender: TObject); //max VAR appParam : JWindowManager_LayoutParams; begin appParam := TAndroidHelper.Activity.getWindow.getAttributes; appParam.screenBrightness := TJWindowManager_LayoutParams.JavaClass.BRIGHTNESS_OVERRIDE_FULL; TAndroidHelper.Activity.getWindow.setAttributes(appParam); end; procedure TForm1.Button3Click(Sender: TObject); //norm VAR appParam : JWindowManager_LayoutParams; begin appParam := TAndroidHelper.Activity.getWindow.getAttributes; appParam.screenBrightness := TJWindowManager_LayoutParams.JavaClass.BRIGHTNESS_OVERRIDE_NONE; TAndroidHelper.Activity.getWindow.setAttributes(appParam); end; I don't understand why it doesn't work, do I have to ask permission for the 64bit app and manually change the brightness?

Hello everyone, Do you know if it is possible to insert a link in your app, which points to the Google Play Store page, to view the list of your applications?

Thanks for the reply, but is it possible to place a link in an application that points to my page? Am I breaking some Google rule?
