Programatically receiving a call and turning on speaker

Question

Is it possible to receive a call and turn on the speaker programmatically in android? Went through many question on stack overflow and google but was not satisfied. Even in AutoAnswer the speaker mode is not working in Jelly Bean. Any help guys?

This is what I get in logcat:

FATAL EXCEPTION: main
java.lang.SecurityException: Neither user 10212 nor current process has android.permission.MODIFY_PHONE_STATE.
    at android.os.Parcel.readException(Parcel.java:1425)
    at android.os.Parcel.readException(Parcel.java:1379)
    at com.android.internal.telephony.ITelephony$Stub$Proxy.answerRingingCall(ITelephony.java:798)
    at com.example.thu.Callclass$Calllistener.onSensorChanged(Callclass.java:144)
    at android.hardware.SystemSensorManager$ListenerDelegate$1.handleMessage(SystemSensorManager.java:250)

@RobertHarvey : I meant even if I select Speaker in AutoAnswer, it receives the call but is unable to turn on the speaker. — Sparkplug, Oct 26 '13 at 18:31
@nOiAd: +1, but there's already some code to look at in the link provided. — Robert Harvey, Oct 26 '13 at 18:32
Ah, enlightenment. `Neither user 10212 nor current process has android.permission.MODIFY_PHONE_STATE` — Robert Harvey, Oct 26 '13 at 18:41
@RobertHarvey: I have added MODIFY_PHONE_STATE permission. I think this is a system level permission that is not accessible to apps. But there are apps on the playstore that can modify Phone State!! — Sparkplug, Oct 26 '13 at 18:43
+1 to the question. Even i am facing the same problem. I have tried the Itelephony api, but it is no longer usable. Then I have tried the code of autanswer, but the problem is speakerphone is not getting activated. — Vyshakh, Oct 26 '13 at 18:46

You need to add this permission to your manifest file:

    <uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />

yes. I have added this. But it is no longer accessible by apps. This is a system level permission now. What i want to now is whether there is an alternative to this? Because there are some apps in the play stor that does these tasks. – Vyshakh Oct 26 '13 at 18:51

@vish Yes, but it only actually _works_ on Froyo and older devices. [Since Gingerbread it no longer works except for system apps](http://stackoverflow.com/q/4715250/1068283). – Michael Hampton Oct 26 '13 at 21:30
