android2.3之上自动接听来电

因为Android2.3以上增加了对permission ?android.permission.MODIFY_PHONE_STATE 的限制，2.3之前的通过反射机制调用ITelephone的能力的做法已经不适用

?

2.3上实现方式：

public synchronized void answerRingingCall() {		// 据说该方法只能用于Android2.3及2.3以上的版本上		try {			Intent localIntent1 = new Intent(Intent.ACTION_HEADSET_PLUG);			localIntent1.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);			localIntent1.putExtra("state", 1);			localIntent1.putExtra("microphone", 1);			localIntent1.putExtra("name", "Headset");			sendOrderedBroadcast(localIntent1,					"android.permission.CALL_PRIVILEGED");			Intent localIntent2 = new Intent(Intent.ACTION_MEDIA_BUTTON);			KeyEvent localKeyEvent1 = new KeyEvent(KeyEvent.ACTION_DOWN,					KeyEvent.KEYCODE_HEADSETHOOK);			localIntent2.putExtra("android.intent.extra.KEY_EVENT",					localKeyEvent1);			sendOrderedBroadcast(localIntent2,					"android.permission.CALL_PRIVILEGED");			Intent localIntent3 = new Intent(Intent.ACTION_MEDIA_BUTTON);			KeyEvent localKeyEvent2 = new KeyEvent(KeyEvent.ACTION_UP,					KeyEvent.KEYCODE_HEADSETHOOK);			localIntent3.putExtra("android.intent.extra.KEY_EVENT",					localKeyEvent2);			sendOrderedBroadcast(localIntent3,					"android.permission.CALL_PRIVILEGED");			Intent localIntent4 = new Intent(Intent.ACTION_HEADSET_PLUG);			localIntent4.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);			localIntent4.putExtra("state", 0);			localIntent4.putExtra("microphone", 1);			localIntent4.putExtra("name", "Headset");			sendOrderedBroadcast(localIntent4,					"android.permission.CALL_PRIVILEGED");		} catch (Exception e) {			e.printStackTrace();		}	}
