Android v4.0,4.1 (ICS, ICS2, JB)

Android V4.2 (JB2,JB3,JB5)

Android V4.4

Android V5.0,5.1

[DESCRIPTION]

If you need to customize the behavior that the phone vibrates when the call is connected or disconnected, you can refer to the following modifications

[SOLUTION]

When the call is connected:

Versions prior to Android V4.4:

1 add private Vibrator mVibrator at the beginning of packages\ apps\ phone\ src\ com\ android\ phone\ CallNotifier.java

2 add at the beginning of the packages\ apps\ phone\ src\ com\ android\ phone\ CallNotifier.java function onPhoneStateChanged

If (mVibrator = = null) {

MVibrator = (Vibrator)

MApplication.getApplicationContext () getSystemService (Context.VIBRATOR_SERVICE)

}

3 add a member variable to packages\ apps\ phone\ src\ com\ android\ phone\ CallNotifier.java

Call.State mLastCallState = Call.State.IDLE

Then add the following code to the statement Phone fgPhone = mCM.getFgPhone (); in the function onPhoneStateChanged

Call.State ringCallState =

MCM.getRingingPhone (). GetRingingCall (). GetState ()

Call.State fgCallState = mCM.getActiveFgCallState ()

If ((ringCallState==Call.State.IDLE & & mLastCallState.isRinging ()) | | / / MT

(fgCallState==Call.State.ACTIVE & & mLastCallState.isDialing ()) / / MO

{

/ / here means that call is connected

Final int MO_CALL_VIBRATE_TIME = 300; / / msec

MVibrator.vibrate (MO_CALL_VIBRATE_TIME)

}

MLastCallState = ringCallState.isRinging ()? RingCallState:fgCallState

MtkAndroid V4.4 and later:

This feature is already available.

After hanging up:

In CallNotifier.java onDisconnect ()

Phone.State state = mCM.getState (); add the following Code

If (mVibrator = = null) {

MVibrator = (Vibrator)

MApplication.getApplicationContext () getSystemService (Context.VIBRATOR_SERVICE)

}

Final int CALL_DISC_VIBRATE_TIME = 300; / / msec

MVibrator.vibrate (CALL_DISC_VIBRATE_TIME)
