android2.3以上自動着信

なぜならAndroid 2.3以上はpermission androidに増加した.permission.MODIFY_PHONE_STATEの制限、2.3以前の反射メカニズムでITelephoneを呼び出す能力は適用されていません
 
2.3上の実現方式:

public synchronized void answerRingingCall() {
		//          Android2.3 2.3      
		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();
		}
