[Android]Android5.0实现静默接听电话功能

Posted 2020-09-21

原因：

android曾经能够通过AIDL进行静默接听。可是5.0以后就被谷歌给屏蔽了。这时候我们仅仅能通过其它方式实现了。

解决方式：

try {
            Runtime.getRuntime().exec("input keyevent " +
                    Integer.toString(KeyEvent.KEYCODE_HEADSETHOOK));
        } catch (IOException e) {
            // Runtime.exec(String) had an I/O problem, try to fall back
            String enforcedPerm = "android.permission.CALL_PRIVILEGED";
            Intent btnDown = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
                    Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_DOWN,
                            KeyEvent.KEYCODE_HEADSETHOOK));
            Intent btnUp = new Intent(Intent.ACTION_MEDIA_BUTTON).putExtra(
                    Intent.EXTRA_KEY_EVENT, new KeyEvent(KeyEvent.ACTION_UP,
                            KeyEvent.KEYCODE_HEADSETHOOK));

            mContext.sendOrderedBroadcast(btnDown, enforcedPerm);
            mContext.sendOrderedBroadcast(btnUp, enforcedPerm);
        }

简单说就是发送一个耳机按下接听的事件。欺骗系统。
