Handling Android application pause on incoming call and resume after call end

Question

I want to pause my android application when the phone receives an incoming call. After the call ends, I want my applications to resume automatically.

How would this

Answer 1

private class EndCallListener extends PhoneStateListener {
  private boolean active = false;
  @Override
  public void onCallStateChanged(int state, String incomingNumber) {
    if(TelephonyManager.CALL_STATE_RINGING == state) {
      Log.i("EndCallListener", "RINGING, number: " + incomingNumber);
    }
    if(TelephonyManager.CALL_STATE_OFFHOOK == state) {
      //wait for phone to go offhook (probably set a boolean flag) so you know your app initiated the call.
      active = true;
      Log.i("EndCallListener", "OFFHOOK");
    }
    if(TelephonyManager.CALL_STATE_IDLE == state) {
      //when this state occurs, and your flag is set, restart your app
      Log.i("EndCallListener", "IDLE");
      if (active) {
        active = false;
        // stop listening                   
        TelephonyManager mTM = (TelephonyManager) m_activity.getSystemService( Context.TELEPHONY_SERVICE );
        mTM.listen(this, PhoneStateListener.LISTEN_NONE);
        // restart the inbox activity
        //Intent intent = new Intent(m_activity, MDInboxActivity.class);
        //m_activity.startActivity(intent);
      }
    }
  }
}

And you can initialize the above class by calling the below lines:

try {
  EndCallListener callListener = new EndCallListener();
  TelephonyManager mTM = (TelephonyManager) m_activity.getSystemService(Context.TELEPHONY_SERVICE);
  mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
} catch(Exception e) {
  Log.e("callMonitor", "Exception: "+e.toString());
}
