Call from sim 2

Maher Tannous · December 26, 2019

hello
please i need help
i want to call a number from sim2 card

I want to request USSD code from sim2 slot without change any thing in android settings
any help to do that in delphi fmx android

some one send me this

Intent intent = new Intent(Intent.ACTION_CALL);
intent.putExtra("com.android.phone.extra.slot", 1); //For sim 2
intent.putExtra("simSlot", 1); //For sim 2
intent.setData(Uri.parse("tel:" + "**********"));

I tried this without success
I replaced "com.android.phone.extra.slot" with TJIntent.JavaClass.EXTRA_PHONE_NUMBER
but I can't find any thing to replace with "simSlot" ????

My code :

uses
Androidapi.JNI.GraphicsContentViewText,
Androidapi.JNI.Net,
var
mobilenumber : string;
Intent : JIntent;
Begin
mobilenumber:='*155#';
Intent := TJIntent.Create;
Intent.setAction(TJIntent.JavaClass.ACTION_CALL); Intent.putExtra(TJIntent.JavaClass.EXTRA_PHONE_NUMBER, 1);
Intent.putExtra(TJIntent.JavaClass.EXTRA_INDEX, 1);
Intent.setData(TJnet_Uri.JavaClass.parse
(StringtoJString(mobilenumber)));
TAndroidHelper.Context.startActivity(Intent);
End;

Your code does not match the Java equivalent that has been sent to you. This is the equivalent:

uses
  Androidapi.JNI.GraphicsContentViewText, Androidapi.JNI.Net, Androidapi.Helpers;

procedure TForm1.Button1Click(Sender: TObject);
var
  MobileNumber: string;
  Intent: JIntent;
begin
  MobileNumber := '*155#';
  Intent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_CALL);
  Intent.putExtra(StringToJString('com.android.phone.extra.slot'), 1);
  Intent.putExtra(StringToJString('simSlot'), 1);
  Intent.setData(TJnet_Uri.JavaClass.parse(StringtoJString('tel:' + MobileNumber)));
  TAndroidHelper.Context.startActivity(Intent);
end;

I don't have a dual SIM device to test this.

Those are not equivalent. TJIntent.JavaClass.EXTRA_PHONE_NUMBER is "android.intent.extra.PHONE_NUMBER", not "com.android.phone.extra.slot"

December 26, 2019

@Dave Nottage I confirm that your code works on second SIM.

sorry for that but it does not work

your code is asking me to choose between sim card and if I choose sim 2

it calling the number *155

it does not run ussd code for *155#

it removes # and call *155

may be some one can test the code and tell me what happining

Thanks

@Maher Tannous In my case it didn't ask to select between sims, and for the # it should be replaced with %23 so phone number should be:

MobileNumber := '*155%23';

have you tried to call from sim 2 ?

December 26, 2019

Dave's code automatically made a call directly using SIM 2, the phone did not ask me to choose a sim.

December 26, 2019

My 4.4.2 Android is configured to ask me on each call i make to choose a sim to be used, with that code it i didn't even ask me.

Maher Tannous · December 26, 2019

my android version is 9

samsung j7 pro

and I configured to ask me on each call i make to choose a sim to be used

and it always show me dialog to choose sim to call from

maybe the problem in android version

December 26, 2019

May be it is a system feature,bug, changes , security thing ....

, i suggest consulting with Google on that matter, you might find some answers,

Good luck.

December 27, 2019

@Maher Tannous Try this code as it solved similar behaviour like yours on Android 6, and i think this is the right way to format phone numbers with #

procedure CallByPhoneNumber(const PhoneNumber: string; SIMindex: Integer);
var
  Intent: JIntent;
begin
  Intent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_CALL);
    //Intent.putExtra(StringToJString('com.android.phone.force.slot'), true);
    //Intent.putExtra(StringToJString('Cdma_Supp'), True);

  Intent.putExtra(StringToJString('extra_asus_dial_use_dualsim'), SIMindex);
  Intent.putExtra(StringToJString('com.android.phone.extra.slot'), SIMindex);
  Intent.putExtra(StringToJString('slot'), SIMindex);
  Intent.putExtra(StringToJString('simslot'), SIMindex);
  Intent.putExtra(StringToJString('sim_slot'), SIMindex);
  Intent.putExtra(StringToJString('subscription'), SIMindex);
  Intent.putExtra(StringToJString('Subscription'), SIMindex);
  Intent.putExtra(StringToJString('phone'), SIMindex);
  Intent.putExtra(StringToJString('com.android.phone.DialingMode'), SIMindex);
  Intent.putExtra(StringToJString('simSlot'), SIMindex);
  Intent.putExtra(StringToJString('slot_id'), SIMindex);
  Intent.putExtra(StringToJString('simId'), SIMindex);
  Intent.putExtra(StringToJString('simnum'), SIMindex);
  Intent.putExtra(StringToJString('phone_type'), SIMindex);
  Intent.putExtra(StringToJString('slotId'), SIMindex);
  Intent.putExtra(StringToJString('slotIdx'), SIMindex);

  Intent.setData(TJnet_Uri.JavaClass.parse(StringToJString('tel:' +
    JStringToString(TJnet_Uri.JavaClass.encode(StringToJString(PhoneNumber))))));
  TAndroidHelper.Context.startActivity(Intent);
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  CallByPhoneNumber('*111#', 0);   // 0 for SIM1
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
  CallByPhoneNumber('*111#', 1);   // 1 for SIM2
end;

i have no idea how to import TelecomManager

Maher Tannous · December 27, 2019

This to call TelecomManager

var
telService: JObject;

telService := TAndroidHelper.Activity.getSystemService
(TJContext.JavaClass.TELECOM_SERVICE);

But the problem is how to call : getCallCapablePhoneAccounts

There's an import for TelecomManager, here:

https://github.com/FMXExpress/android-object-pascal-wrapper/blob/master/android-28/android.telecom.TelecomManager.pas

Be aware that Java2Pas (which was used for the import) sometimes puts instance methods where the class methods are, so they should be removed from there in the import.

getCallCapablePhoneAccounts is an instance method that returns a JList, containing instances of JPhoneAccountHandle, so one way to access them is to do this:

var
  LService: JObject;
  LAccounts: JList;
  LPhoneAccountHandle: JPhoneAccountHandle;
  I: Integer;
begin
  Result := False;
  LService := TAndroidHelper.Context.getSystemService(TJContext.JavaClass.TELECOM_SERVICE);
  LAccounts := TJTelecomManager.Wrap(TAndroidHelper.JObjectToID(LService)).getCallCapablePhoneAccounts;
  for I := 0 to LAccounts.size - 1 do
  begin
    LPhoneAccountHandle := TJPhoneAccountHandle.Wrap(TAndroidHelper.JObjectToID(LAccounts.get(I)));
    // Do whatever with the LPhoneAccountHandle here
  end;
end;

An import for PhoneAccountHandle is here:

https://github.com/FMXExpress/android-object-pascal-wrapper/blob/master/android-28/android.telecom.PhoneAccountHandle.pas

Note that getCallCapablePhoneAccounts was introduced in API level 23.

December 28, 2019

@Dave Nottage Thank you .

This raise a question about raised exception and i know you are the right person to ask

Quote

Invoke error: method not found

raised on LService := TAndroidHelper.Context.getSystemService(TJContext.JavaClass.TELECOM_SERVICE);

The question is : Is there right way to handle this ?

i mean my phone API level is 19 and TELECOM_SERVICE is not there, should i use try..except or there is a method to check class existence without raising an exception ?

This is one way:

if TOSVersion.Check(21) then
begin
  // Do the TELECOM_SERVICE stuff
end;

TELECOM_SERVICE was introduced in API level 21. Another way is:

if TJBuild_VERSION.JavaClass.SDK_INT >= 21 then
begin
  // Do the TELECOM_SERVICE stuff
end;

but

I have to put all files from this page

I've created a more compatible (with the other Delphi units) import for the Telecom classes, here:

https://github.com/DelphiWorlds/KastriFree/blob/master/API/DW.Androidapi.JNI.Telecom.pas

Which should at least make it a bit easier

I got an error here ( LAccounts.get(0) )

it returns an TJObject

but Intent.putExtra reqired a Byte

That part should be more like this:

  LAccounts := TJTelecomManager.Wrap(TAndroidHelper.JObjectToID(LService)).getCallCapablePhoneAccounts;
  if LAccounts <> nil then
  begin
    for I := 0 to 1 do
    begin

        Intent.putExtra(StringToJString('android.telecom.extra.PHONE_ACCOUNT_HANDLE'), LPhoneAccountHandle);

Intent.putExtra(StringToJString('android.telecom.extra.PHONE_ACCOUNT_HANDLE'), LPhoneAccountHandle);

does not accept

LPhoneAccountHandle

I must use JString or integer value

Dave Nottage · January 2, 2020

Actually putExtra takes a number of different types, including JParcelable. I've modified the Telecom import unit:

https://github.com/DelphiWorlds/KastriFree/blob/master/API/DW.Androidapi.JNI.Telecom.pas

So if you update that, it should now accept LAccountHandle

Thank you very much

this is my working code

1- Use this unit https://github.com/DelphiWorlds/KastriFree/blob/master/API/DW.Androidapi.JNI.Telecom.pas
