Question

我可以看到很多已经在SO上问过的问题，但是没有一个问题有正确的答案。

SO和博客上的大多数建议都在下面的代码段中提供建议：

var buttonDown = Intent(Intent.ACTION_MEDIA_BUTTON)
    buttonDown.putExtra(Intent.EXTRA_KEY_EVENT,
            KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK))
    sendOrderedBroadcast(buttonDown, "android.permission.CALL_PRIVILEGED")

    var buttonDown1 = Intent(Intent.ACTION_MEDIA_BUTTON)
    buttonDown.putExtra(Intent.EXTRA_KEY_EVENT,
            KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK))
    sendOrderedBroadcast(buttonDown1, "android.permission.CALL_PRIVILEGED")

但是，它不起作用，并引发错误，指出第三方应用程序不允许使用“ CALL_PRIVILEGED”。

一些帖子和答案建议使用下面的代码段。

Runtime.getRuntime().exec("input keyevent " + Integer.toString(KeyEvent.KEYCODE_HEADSETHOOK))

但是不幸的是，这也没有帮助我。我知道我们有来自android框架的现成方法，可以接受Oreo以上api级的调用和结束调用。但是我也需要在oreo下实现此功能。

我发现下面的代码使用反射拒绝了呼叫，并且工作正常。

try {

        var serviceManagerName = "android.os.ServiceManager"
        var serviceManagerNativeName = "android.os.ServiceManagerNative"
        var telephonyName = "com.android.internal.telephony.ITelephony"
        var telephonyClass: Class<*>
        var telephonyStubClass: Class<*>
        var serviceManagerClass: Class<*>
        var serviceManagerNativeClass: Class<*>
        var telephonyEndCall: Method
        var telephonyObject: Object
        var serviceManagerObject: Object
        telephonyClass = Class.forName(telephonyName);
        telephonyStubClass = telephonyClass.getClasses()[0];
        serviceManagerClass = Class.forName(serviceManagerName);
        serviceManagerNativeClass = Class.forName(serviceManagerNativeName);
        var getService = // getDefaults[29];
                serviceManagerClass.getMethod("getService", String::class.java)
        var tempInterfaceMethod = serviceManagerNativeClass.getMethod("asInterface", IBinder::class.java)
        var tmpBinder = Binder()
        tmpBinder.attachInterface(null, "fake");
        serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder) as Object;
        var retbinder = getService.invoke(serviceManagerObject, "phone") as IBinder
        var serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder::class.java)
        telephonyObject = serviceMethod.invoke(null, retbinder) as Object;
        telephonyEndCall = telephonyClass.getMethod("endCall")
        telephonyEndCall.invoke(telephonyObject)

    } catch (e: InvocationTargetException) {
        e.printStackTrace()
        Log.d("unable", "msg cant dissconect call....")
    }

但是类似的接受呼叫的方式无效。

try {
        var telephonyManager = getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
        // Get the getITelephony() method
        val classTelephony = Class.forName(telephonyManager.javaClass.name)
        val method = classTelephony.getDeclaredMethod("getITelephony")
        // Disable access check
        method.isAccessible = true
        // Invoke getITelephony() to get the ITelephony interface
        val telephonyInterface = method.invoke(telephonyManager)
        // Get the endCall method from ITelephony
        val telephonyInterfaceClass = Class.forName(telephonyInterface.javaClass.name)
        val methodEndCall = telephonyInterfaceClass.getMethod("answerRingingCall")
        // Invoke endCall()
        methodEndCall.invoke(telephonyInterface)

    } catch (e: Exception) {
        Log.e(TAG,"Unable to accept call")
        e.printStackTrace()
    }

有人可以告诉我在所有API级别中是否都有适当的方法来处理android中的接受，拒绝传入和断开传出呼叫吗？

如何以编程方式接受/拒绝android传入和断开传出呼叫？
