I use the following code: unit Unit2; interface uses System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Graphics, FMX.Dialogs, FMX.Controls.Presentation, FMX.StdCtrls, FMX.WebBrowser, IOUtils, System.Permissions, Androidapi.Jni.Os, Androidapi.Helpers, FMX.Memo.Types, FMX.ScrollBox, FMX.Memo; type TForm2 = class(TForm) WebBrowser1: TWebBrowser; Button1: TButton; Label1: TLabel; Button2: TButton; Button3: TButton; Button4: TButton; procedure Button1Click(Sender: TObject); procedure Button2Click(Sender: TObject); procedure Button3Click(Sender: TObject); procedure Button4Click(Sender: TObject); procedure FormCreate(Sender: TObject); private { Private declarations } public { Public declarations } end; var Form2: TForm2; FPermissionWrite: string; FPermissionRead: string; fileName:string; implementation {$R *.fmx} procedure TForm2.Button1Click(Sender: TObject); begin fileName:= (TPath.Combine(TPath.GetSharedDownloadsPath,'001.pdf')); if FileExists(fileName) then WebBrowser1.Navigate('file:/'+fileName) else ShowMessage('11:'); end; procedure TForm2.Button2Click(Sender: TObject); begin Application.Terminate; end; procedure TForm2.Button4Click(Sender: TObject); begin PermissionsService.RequestPermissions([FPermissionWrite], procedure(const APermissions: TArray<string>; const AGrantResults: TArray<TPermissionStatus>) begin if (Length(AGrantResults) = 1) and (AGrantResults[0] = TPermissionStatus.Granted) then ShowMessage('Access is available') else ShowMessage('Permission Denied'); end); if PermissionsService.IsPermissionGranted (JStringToString(TJManifest_Permission.JavaClass.WRITE_EXTERNAL_STORAGE)) and PermissionsService.IsPermissionGranted (JStringToString(TJManifest_Permission.JavaClass.READ_EXTERNAL_STORAGE)) then ShowMessage ('access has ALREADY been granted!') else ShowMessage ('001'); end; procedure TForm2.FormCreate(Sender: TObject); begin FPermissionWrite := JStringToString(TJManifest_permission.JavaClass.WRITE_EXTERNAL_STORAGE); FPermissionRead := JStringToString(TJManifest_permission.JavaClass.READ_EXTERNAL_STORAGE); end; end. here WebBrowser1.Navigate ('file:/' +fileName) error occurs: the specified file was not found on a smartphone, the file is created at: /storage/emulated/0/Android/data/com.embarcadero.Project5/files/001.pdf

I want to learn how to work in RAD Studio, I need a mentor who will help me get out of a difficult situation. what issues do I need help with?: 1) teach me to read mistakes 2) teach you how to use the help 3) learn how to use hints in RedStudio I believe that these things can be learned by yourself, but with a mentor, learning will go faster. Why do I need a mentor? I installed RED Studio and tried to run the application (which is located in the Examples folder) for Android, the number of SDK errors that I fixed is п..здец (very - author's note) is great, my experience tells me that with the initial installation it should not be so, with the initial installation (on ready-made Examples) everything should go "like clockwork". Briefly about yourself: 1) The man 2) 36 years old 3) I have been working in the IT field since 2008 4) I speak Russian (I speak English through Google) Suggestions for the mentor: 1) at least three years of experience with RAD Studio Hourly payment (I ask a question in Skype, the mentor evaluates it, the mentor If you are interested in my offer, please write to the post office the cost of one hour

Thank you very much for all the help, the mentoring was done by @vfbb in a very satisfactory way, and here is my recommendation.

thank you for your advice, this is a good resource. but it seems to me that at the first steps it is better to have a mentor, then forums, books and the entire Internet 🙂

thank you for your advice

thanks for the advice, because of big brother I don't like social networks (maybe this is nonsense, don't judge me for it strictly)

thank you for your advice, I completely agree with you: there are many books and information in English (I have read many such books and articles). I can read in English, my conversational language is poor(((

I give you a hint: I correspond with you in English 😉

sql.ru - I didn't know about this resource. at the expense of my English-the main thing is that I strive for knowledge, and in this way all means are good (even an on-line translator).

MVP-gives training materials or does he give a mentor?
