如何显示应用UI以接受和拒绝视频通话，并防止与其他正在进行的应用冲突？

Question

我在Android应用程序中工作，用户接受或拒绝视频通话，这是正常的。但现在我想防止应用程序与其他人发生冲突，如果我们有任何其他调用，如应用程序或Skype。

然后我读了self managed connectionservice并尝试实现它。

Here is complete doc

从活动我首先注册

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.addNewIncomingCall（phoneAccountHandle，extras）上崩溃，后面跟着日志
