B4A Library AnswerCall Library

XverhelstX · Nov 29, 2011

Hello everyone,

SoyEli wanted to answer a call automatically in this topic, so I created this library.

It works together with Erel's PhoneEvents PhoneStateChanged.

Note that you should respect the order of events of the sample in phonestateChanged and that it will only work in a service.

B4X:

Sub PE_PhoneStateChanged (State As String, IncomingNumber As String, Intent As Intent)
    Log("PhoneStateChanged, State = " & State & ", IncomingNumber = " & IncomingNumber)
    Log(Intent.ExtrasToString)
   AC.LetPhoneRing(3000)
   If AC.isRinging == True Then
      AC.AnswerPhone
   End If
   AC.enableSpeakerphone
End Sub

It may not work on all devices (if you can test it out?)
It worked for my Xperia PLAY.

Attachements include the library files and a sample

ac.enablespeakerphone notworking

Very nice lib but the enablespeakerphone function does not work on my samsung galaxy y duos. :signOops:
The log reports:
Audio Settings Permission Denial: SetSpeakerphoneOn() from pid 32019, uid 10099

Can anything be done for this?

Thanks for all that great work!!

Add this line to the manifest editor:

B4X:

AddPermission(android.permission.MODIFY_AUDIO_SETTINGS)

Maartensaps · Nov 13, 2012

Works !

That does it. THANKS !!:sign0188:

still a little issue

Hi Erel,

Your solution works on a Samsung phone but...
Does a HTC evo WiMax do things diferently?
The speaker does not switch on :-(

Any ideas?

Erel · Nov 17, 2012

What exactly are you trying to achieve?
I'm not really familiar with this library.

Maartensaps · Nov 17, 2012

I am trying to.....

Pick up the phone and switch on the speaker. A simple auto-answer app.

NeoTechni · Nov 18, 2012

I have it set to allow the user to disable the answering abilities in my app, is there a way to turn this off? ie: an enabled property

Or will all calls go through this no matter what?

EDIT: nevermind, it works perfectly.

NeoTechni · Nov 20, 2012

I've added it to my program, but if the display is off when it attempts to answer the call, the lockscreen comes up. Is there any way to bypass this?
Ronny posted a link to this in another forum http://developer.android.com/reference/android/app/KeyguardManager.KeyguardLock.html
Can you add that to the library?

Also, how does it handle call waiting?

Erel · Nov 20, 2012

This link might be helpful: Unlock password locked screen?

Yes, that's perfect. Ty

Maartensaps · Nov 21, 2012

still some issues

I still have some issues.

On a HTC EVO the speaker does not switch on.

On a Star W007 it does not answer calls.

Any ideas ? Can it be a permission issue or android incompatibility ???

The app is compiled with api 16 (I think, as I can not find out where this is set)

Check the logs and see whether there is any message related to permissions.

I will..... as soon as I figure out how to get the phone-log into a file. (see #post136606)
I do not have those phones. That is the problem. :-(

NeoTechni · Dec 2, 2012

A user on an HTC Thunderbolt reports when they click answer, the call gets sent to voicemail.

Is there a mute microphone setting?

brelto85 · Jan 30, 2013

on my HTC ONE S don't works!!!

Is possible to do this?

alberto

NeoTechni · Mar 6, 2013

HTC EVO 4g wont answer calls

Also, could you add the ability to handle 2 calls at once?
ie: keep track of the phone number for both, switch between them, or release a specific one?

NeoTechni · Mar 8, 2013

So for those of you having problems with HTC devices not answering calls

You need my keycode transmitter library
http://www.b4x.com/forum/additional...lib-control-system-media-player-your-app.html

B4X:

dim keyg As MediaController
keyg.MediaButton(KeyCodes.KEYCODE_HEADSETHOOK)

The KeyGen library will not work for it, I tried it first (hence the variable name)

GMan · May 11, 2014

can i "listen" to the phone and check, wether the dial tone is (still) heared or not ?
So that i can code a routine with maybe if...then... or similiar.

(This in case that i cant trigger the phonehook up on the other side)

In another Thread depending on the phone lib i asked the same:
http://www.b4x.com/android/forum/threads/phone-library-phone-call-check-if.40865/#post-244882
(So, don't know if it is really a double-post)

This line looks wrong:
If numbers(i).Contains(IncomingNumber) Then
