自定义拨号器呼叫无法接通问题排查

正在基于ConnectionService、Connection实现自定义原生拨号器，注册PhoneAccount用于外呼，目前已能通过自定义PhoneAccount发起呼叫，但呼叫始终无法接通至目标号码，请求协助排查。

PhoneAccount注册代码

@RequiresApi(api = Build.VERSION_CODES.M)
private void registerConnectionService() {
    try {
        TelecomManager manager = (TelecomManager) getSystemService(Context.TELECOM_SERVICE);
        String connectionServiceId = getConnectionServiceId();
        ComponentName componentName = new ComponentName(getApplicationContext(), MyService.class);
        PhoneAccountHandle phoneAccountHandle = new PhoneAccountHandle(componentName, "Dialer");
        phoneAccount = manager.getPhoneAccount(phoneAccountHandle);
        // Log.i("phoneAccountTekV",phoneAccount.getAddress()+" "+phoneAccount.getCapabilities()+"  "+phoneAccount.getLabel());
        if (phoneAccount == null) { // no phone account from us registered yet
            PhoneAccount.Builder builder = PhoneAccount.builder(phoneAccountHandle, "Dialer");
            Uri uri = Uri.parse("tel:123456789");
            //builder.setSubscriptionAddress(uri);
            //builder.setAddress(uri);
            builder.setCapabilities(PhoneAccount.CAPABILITY_CALL_PROVIDER);
           
            phoneAccount = builder.build();
            manager.registerPhoneAccount(phoneAccount);
            Log.i("phoneAccount", "" + phoneAccount.isEnabled());
            Intent intent = new Intent();
            intent.setComponent(new ComponentName("com.android.server.telecom",
                    "com.android.server.telecom.settings.EnableAccountPreferenceActivity"));
            startActivity(intent);
        }
        Log.i("is phoneAccountEnabled", "" + phoneAccount.isEnabled());
    } catch (SecurityException se) {
        Log.e("registerPhoneAccount", "SecurityException: Ensure all necessary permissions are granted", se);
    } catch (IllegalArgumentException iae) {
        Log.e("registerPhoneAccount", "IllegalArgumentException: Ensure the PhoneAccount is properly configured", iae);
    } catch (RuntimeException re) {
        Log.e("registerPhoneAccount", "RuntimeException: An unexpected error occurred", re);
    } catch (Exception re) {
        Log.e("registerPhoneAccount", "Exception: An unexpected error occurred", re);
    }
}

ConnectionService实现代码

@RequiresApi(api = Build.VERSION_CODES.Q)
@RequiresPermission(value = "android.permission.READ_PHONE_STATE")
@Override
public Connection onCreateOutgoingConnection(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest originalRequest) {
    Uri handle = originalRequest.getAddress();
    MyConnection connection = new MyConnection(false, originalRequest,this);
    connection.setAddress(handle, TelecomManager.PRESENTATION_ALLOWED);
    //connection.setConnectionProperties(Connection.PROPERTY_SELF_MANAGED);
   // connection.setDialing();
    connection.setInitializing();
    connection.setConnectionCapabilities(Connection.CAPABILITY_HOLD | Connection.CAPABILITY_MUTE | Connection.CAPABILITY_SUPPORT_HOLD);
    connection.setVideoState(originalRequest.getVideoState());
    addCall(connection);
    TelecomManager manager = (TelecomManager) getSystemService(Context.TELECOM_SERVICE);
    boolean isOut = manager.isOutgoingCallPermitted(connectionManagerPhoneAccount);
    Log.i("phoneAccountTekV",connectionManagerPhoneAccount.getUserHandle().toString());
            //setAddress(connection,handle);
    Log.i("isOutgoingCallPermitted"," isOutgoingCallPermitted-"+isOut);
    PhoneAccountHandle ph = manager.getUserSelectedOutgoingPhoneAccount();
    List<PhoneAccountHandle>  selfHandles =manager.getSelfManagedPhoneAccounts();
    List<PhoneAccountHandle>  handles =manager.getCallCapablePhoneAccounts();
    connection.startOutgoing();
    return connection;
}

排查关键点

核心日志警告分析：Call: maybeOnInCallServiceTrackingChanged() request on a call without a connection service 说明Telecom系统未识别到呼叫关联的有效ConnectionService，需检查Connection状态流转和服务配置。
PhoneAccount配置修正：
- 注册时添加PhoneAccount.CAPABILITY_SELF_MANAGED权限，确保系统将通话控制权交给自定义服务：builder.setCapabilities(PhoneAccount.CAPABILITY_CALL_PROVIDER | PhoneAccount.CAPABILITY_SELF_MANAGED)
- 取消注释builder.setSubscriptionAddress(uri)或builder.setAddress(uri)，为PhoneAccount设置有效地址标识，部分系统依赖该字段验证账户合法性。
Connection状态与属性修正：
- 取消注释connection.setConnectionProperties(Connection.PROPERTY_SELF_MANAGED)，明确标记为自管理通话。
- 补充状态流转逻辑：创建Connection后调用connection.setDialing()标记拨号中，待实际通话接通后调用connection.setConnected()，系统需要明确状态更新才能正确处理通话。

Manifest与权限检查：

确保ConnectionService在Manifest中正确注册并绑定权限：

<service
    android:name=".MyService"
    android:permission="android.permission.BIND_CONNECTION_SERVICE">
    <intent-filter>
        <action android:name="android.telecom.ConnectionService" />
    </intent-filter>
</service>

确认已授予READ_PHONE_STATE、CALL_PHONE等必要动态权限（Android 6.0+）。

补充通话发起逻辑：onCreateOutgoingConnection仅创建了Connection对象，需在MyConnection内部实现实际的呼叫建立逻辑（如SIP、VoIP调用），并在逻辑完成后更新Connection状态。
