如何向应用程序UI显示接受和拒绝视频呼叫，并防止与其他应用程序上的其他人冲突

Question

我在一个Android应用中工作，用户接受或拒绝正常工作的视频通话。但是现在，如果我们有其他呼叫，例如应用程序或Skype，我想防止应用程序与他人发生冲突。

我然后阅读了自我管理的Connectionservice并尝试实现它。

这是完整的doc

来自活动我首次注册

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);
    }

然后尝试通过以下操作来添加新调用：

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);

app始终在tm.addnewincomingcall（PhoneAccounthandle，Extras）上崩溃，以下日志

Answer 1

看起来您在AndroidManifest.xml中没有Manage_own_calls的权限

Answer 2

正确注册您的PhoneAccount，然后使用addNewIncomingCall()。就我而言，它起作用了。

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