I followed this tutorial step by step Mobile Tutorial: Using SQLite (iOS and Android) but when I deploy my application on my android device and attempt to add an entry, I get the following error "unable to open database file"
Here is a snippet of my code:
procedure TForm1.rappadAfterConnect(Sender: TObject);
begin
rappad.ExecuteDirect('CREATE TABLE IF NOT EXISTS notes(ID INTEGER PRIMARY KEY, title TEXT NOT NULL, content TEXT NOT NULL);');
end;
procedure TForm1.rappadBeforeDisconnect(Sender: TObject);
begin
{$IF DEFINED(iOS) or DEFINED(ANDROID)}
rappad.Params.Values['ColumnMetadataSupported'] := 'False';
rappad.Params.Values['Database'] :=
TPath.Combine(TPath.GetDocumentsPath, 'rappad.s3db');
{$ENDIF}
end;
Does anyone know why is this actually happening? Thanks!
The code you have in your rappadBeforeDisconnect needs to be in BeforeConnect instead. There's no point in telling the connection where the database is located before you disconnect.
procedure TForm1.rappadBeforeConnect(Sender: TObject);
begin
{$IF DEFINED(iOS) or DEFINED(ANDROID)}
rappad.Params.Values['ColumnMetadataSupported'] := 'False';
rappad.Params.Values['Database'] :=
TPath.Combine(TPath.GetDocumentsPath, 'rappad.s3db');
{$ENDIF}
end;

Helo,
I typed the code as follows and this code works well.
By using an https connection I hope that the Packet Data received cannot be read by applications such as Wireshark or the Packet Capture application on Android.
how do you configure the client side?
this my code
procedure TForm1.Button1Click(Sender: TObject);
var
MyCompletionHandler: TCompletionHandler;
MyErrorCompletionHandler: TCompletionHandlerWithError;
begin
ShowLoadingIndicator(Self, True);
Memo1.Lines.Clear;
RESTClient1.BaseURL := 'https://reqres.in/';
RESTClient1.RaiseExceptionOn500 := False;
RESTClient1.SecureProtocols := [THTTPSecureProtocol.TLS12];
RESTRequest1.ClearBody;
RESTRequest1.Resource := 'api/users';
MyCompletionHandler := procedure
var i: Integer;
tJson: TJSONValue;
begin
Label1.Text := 'Complete!';
Memo1.Lines.Append('Header: ');
for I := 0 to RESTResponse1.Headers.Count-1 do
Memo1.Lines.Append(RESTResponse1.Headers.Strings[I]);
Memo1.Lines.Append('');
Memo1.Lines.Append('Body:');
tJson := TJSONObject.ParseJSONValue(RESTResponse1.Content);
try
memo1.Lines.Append(REST.Json.TJson.Format(tJson));
finally
FreeAndNil(tJson);
end;
HideLoadingIndicator(Self);
end;
MyErrorCompletionHandler := procedure(AObject: TObject)
begin
Label1.Text := 'Error!';
HideLoadingIndicator(Self);
end;
RESTRequest1.ExecuteAsync(MyCompletionHandler, True, True, MyErrorCompletionHandler);
end;

I think installing Delphi's Android 5.0 update will help if the device is Android 5.0. I have solved my same problem that way.

I just made an app with Delphi XE6 that receives push notifications with kinvey based on this example
When the application is running and I send a push the PushEvent handler receives it well, but when the application is closed and I press the notification it only opens my app.
Can I know which notification was pressed and get parameters from it?
Thanks in advance.
Edit:
I get a little bit closer, in my FormCreate ask for Extras:
procedure TForm1.FormCreate(Sender: TObject);
var
LIntent: JIntent;
LExtras: JBundle;
LExtrasArray: TJavaObjectArray<AndroidApi.JNI.JavaTypes.JObject>;
begin
LIntent := SharedActivity.getIntent;
try
if LIntent <> nil then
begin
LExtras := LIntent.getExtras;
if LExtras <> nil then
begin
//Now try to get the data
LExtrasArray := LExtras.KeySet.toArray;
for I := 0 to LExtrasArray.Length - 1 do
Memo1.Lines.Add(JStringToString(LExtrasArray.Items[I].toString));
end;
end;
finally
LIntent := nil;
end;
end;
With this code I get "gcm" in my memo.
So, when the notification fires my app I get this Extra available.
Now the problem is how I get info about that extra?
I tried LExtras.getString(StringToJString('message')) but this writes '' instead of the push message
Sarina DuPont answer me in her Blog
PushEvents component has a property StartupNotification for this purpose
procedure TMainForm.FormShow(Sender: TObject);
begin
if Assigned(PushEvents.StartupNotification) then
//Do something here!
//for example
//Memo.Text := PushEvents.StartupNotification.Message;
end;
I am building an application for Android using Delphi XE5 that makes use of the Zxing barcode application and it uses the clipboard to retrieve the result. All of the code (Most of it anyway) is from a tutorial that I have found on the web. When I followed the tutorial, it worked to a charm but when applying the SAME code within an application that I was already working on - it did not work. Whenever accessing the clipboard ( in the 'OnTimer' event), the application always hangs and stops working. No error, nothing. App freezes and I have to close it via the phone's task manager.
The application fails right after the following line
Log.Add('AndroidClipboardScanner:1'); Log.SaveToFile(INIFileLog);
I have changed the coding around so that the app assumed the Clipboard service was available in the Ontimer event and it proceeded but it then failed after the following line:
Log.Add('AndroidClipboardScanner:4'); Log.SaveToFile(INIFileLog);
I am not sure where to begin debugging because the same code works in the other application that I created following the initial guide I found. I can also confirm that the ClipService is being assigned properly, otherwise the intent wouldn't even begin. Any help or guidance would be much appreciated ! Below is my code...
This Declared in the 'Private' variables section of the form:
ClipService: IFMXClipboardService;
This within the 'OnTimer' event for Timer1:
procedure TMain_Form.Timer1Timer(Sender: TObject);
var
barCode : String;
begin
timer1.Enabled := false;
Log.Add('AndroidClipboardScanner:0.1'); Log.SaveToFile(INIFileLog);
Try
if assigned(ClipService) then begin
Log.Add('AndroidClipboardScanner:1'); Log.SaveToFile(INIFileLog);
if (ClipService.GetClipboard.ToString <> 'nil') then
begin
Log.Add('AndroidClipboardScanner:2'); Log.SaveToFile(INIFileLog);
timer1.Enabled := false;
Log.Add('AndroidClipboardScanner:3'); Log.SaveToFile(INIFileLog);
Elapsed := 0;
Log.Add('AndroidClipboardScanner:4'); Log.SaveToFile(INIFileLog);
editHold.PasteFromClipboard;
//EditHold.Text := ClipService.GetClipboard.ToString;
Log.Add('AndroidClipboardScanner:5'); Log.SaveToFile(INIFileLog);
end else
begin
Log.Add('AndroidClipboardScanner:6'); Log.SaveToFile(INIFileLog);
Timer1.Enabled := False;
Log.Add('AndroidClipboardScanner:7'); Log.SaveToFile(INIFileLog);
end;
Log.Add('AndroidClipboardScanner:8'); Log.SaveToFile(INIFileLog);
end else begin
ShowMessage('Unexpected error has occured');
end;
Except
ShowMessage('Unexpected error has occured..');
End;
end;
Within the ONCreate procedure of the form:
if not TPlatformServices.Current.SupportsPlatformService(IFMXClipboardService,
IInterface(ClipService)) then begin
ShowMessage('Clipboard Failed:1');
ClipService := nil;
end;
Elapsed := 0;
This is for click event for the button that begins the intent:
procedure TMain_Form.Button_ShowScannerClick(Sender: TObject);
{$IFDEF ANDROID}
var
intent: JIntent; {$ENDIF}
begin
{$IFDEF ANDROID}
//ShowMessage('Scanner:1');
if assigned(ClipService) then begin
//ShowMessage('Scanner:2');
ClipService.SetClipboard('nil');
intent := tjintent.Create;
intent.setAction(stringtojstring('com.google.zxing.client.android.SCAN'));
intent.putExtra(tjintent.JavaClass.EXTRA_INTENT,
stringtojstring('"SCAN_MODE"'));
sharedactivity.startActivityForResult(intent,0);
Elapsed := 0;
timer1.Enabled := true;
//ShowMessage('Scanner:3');
end;
{$ENDIF}
You didn't set the SCAN_MODE parameters like:
intent.putExtra(tjintent.JavaClass.EXTRA_TEXT,
stringtojstring('"SCAN_MODE","ONE_D_MODE,QR_CODE_MODE,PRODUCT_MODE,DATA_MATRIX_MODE"'));
Also you can check timer interval parameter...
I tested the solution on few devices.
With low interval value I had black screen sometimes
Has anyone been able to take pictures from camera on Android from within the app written in Delphi Firemonkey XE5? How about the video capture?
This is believed to be either a bug in a framework or just something with missing documentation about it.
Can anyone tell why the code bellow doesn't work / retrieve any image from a camera on Android?
Dropped a TCameraComponent on a form, and a TImage component as well, and nothing happens.
procedure TCameraComponentForm.OnCreate(Sender: TObject);
begin
CameraComponent1.Kind := FMX.Media.TCameraKind.ckFrontCamera;
CameraComponent1.FlashMode := FMX.Media.TFlashMode.fmFlashOff;
CameraComponent1.Active := True;
end;
procedure TCameraComponentForm.CameraComponent1SampleBufferReady(
Sender: TObject; const ATime: Int64);
begin
CameraComponent1.SampleBufferToBitmap(Image1.Bitmap, True);
Image1.Width := Image1.Bitmap.Width;
Image1.Height := Image1.Bitmap.Height;
end;
Permissions are set correctly.
This code works fine:
procedure TfrmPrincipal.SampleBufferSync;
begin
cmcPrincipal.SampleBufferToBitmap(imgFoto.Bitmap, true);
end;
procedure TfrmPrincipal.cmcPrincipalSampleBufferReady(Sender: TObject;
const ATime: Int64);
begin
TThread.Synchronize(TThread.CurrentThread, SampleBufferSync);
// CameraComponent1.SampleBufferToBitmap(imgFoto.Bitmap, True);
// imgFoto.Width := imgFoto.Bitmap.Width;
// imgFoto.Height := imgFoto.Bitmap.Height;
end;
procedure TfrmPrincipal.FormShow(Sender: TObject);
begin
cmcPrincipal.Kind := FMX.Media.TCameraKind.ckBackCamera;
try
cmcPrincipal.FlashMode := FMX.Media.TFlashMode.fmFlashOff;
except
end;
cmcPrincipal.Active := True;
end;
