我正在写一个Android应用程序,我需要接听来电,做一些工作,然后结束通话.所有的谷歌搜索后,我能找到两种不同的方式来实现这一二者均不会与最新版本的Android的工作,特别是4.1果冻豆之后.

I.)使用广播接收器中的Java Reflection为"android.intent.action.PHONE_STATE"访问"com.android.internal.telephony.ITelephony".下面的示例代码可以在数百个相关帖子中找到:

@Override
 public void onReceive(Context context, Intent intent) {
  if (!intent.getAction().equals("android.intent.action.PHONE_STATE")) 
    return;

      Class c = Class.forName(telephony.getClass().getName());
      Method m = c.getDeclaredMethod("getITelephony");
      m.setAccessible(true);
      telephonyService = (ITelephony) m.invoke(telephony);
      telephonyService.silenceRinger();

      telephonyService.answerRingingCall();
      Log.v(TAG, "Call answered...");
      //telephonyService.endCall();
  } catch (Exception e) {
   e.printStackTrace();
   Log.e(TAG,
           "FATAL ERROR: could …
