Android：如何自動接聽電話？

Question

我正在嘗試讓我的手機自動接聽電話，但看起來Google通過這種方式刪除了權限：

TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
ITelephony telephonyService;
telephonyService = (ITelephony)m.invoke(tm);
telephonyService.silenceRinger();
telephonyService.answerRingingCall();

因此，我在這里找到其他方法： http : //code.google.com/p/auto-answer/source/browse/trunk/src/com/everysoft/autoanswer/AutoAnswerIntentService.java

// Simulate a press of the headset button to pick up the call
Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);             
buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
context.sendOrderedBroadcast(buttonDown, "android.permission.CALL_PRIVILEGED");

// froyo and beyond trigger on buttonUp instead of buttonDown
Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);               
buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
context.sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED");

但這也不起作用。 我想念什么？

Answer 1

改變以下

context.sendOrderedBroadcast(buttonDown, "android.permission.CALL_PRIVILEGED");

至

context.sendBroadcast(buttonDown);.

與buttonUp相同。 因為sendOrderedBroadcast()可以被其他接收者中止。
