Android 如何显示应用程序界面以接受和拒绝视频通话，并防止与其他正在运行的应用程序发生冲突？

我在一个android应用程序中工作，用户可以接受或拒绝视频通话，这很好。但现在，我想防止应用程序与其他人冲突，如果我们有任何其他呼叫，如what's app或skype

然后我阅读并尝试实现它

从活动一开始注册

TelecomManager tm = (TelecomManager) 
        getSystemService(Context.TELECOM_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M)
    {
        PhoneAccountHandle phoneAccountHandle = new PhoneAccountHandle(
                    new ComponentName(this.getApplicationContext(), MyConService.class),
                    "example");

        PhoneAccount phoneAccount = PhoneAccount.builder(phoneAccountHandle, "example")
                    .setCapabilities(PhoneAccount.CAPABILITY_SELF_MANAGED).build();
        tm.registerPhoneAccount(phoneAccount);

    }

然后尝试通过执行以下操作添加新呼叫：

PhoneAccountHandle phoneAccountHandle = new PhoneAccountHandle(
                    new ComponentName(this.getApplicationContext(), MyConService.class),
                    "example");
Bundle extras = new Bundle();
Uri uri = Uri.fromParts(PhoneAccount.SCHEME_TEL, "11223344", null);
extras.putParcelable(TelecomManager.EXTRA_INCOMING_CALL_ADDRESS, uri);
tm.addNewIncomingCall(phoneAccountHandle, extras);

应用程序总是在tm（phoneAccountHandle，extras）上崩溃，日志如下

看起来您在AndroidManifest.xml中没有权限，请正确注册您的电话帐户，然后使用

addNewIncomingCall（）

。就我而言，它起了作用

telecomManager.registerPhoneAccount（phoneAccount1）；
telecomManager.addNewIncomingCall（myPhoneAccountHandle，bundle）；

嘿，只是个问题；您是否必须使用SIP进行视频通话？不必使用SIP
