Android camera2 api不支持自动对焦设备

我正在使用camera2 api进行相机开发，我注意到它支持传统版本的相机。我的工作是在传统的一个以上的api 21相机没有自动对焦目前我正在使用这一个

 mState = STATE__WAIT_UNLOCK;
    mPreviewCaptureRequestBuilder.set(CaptureRequest.CONTROL_AF_TRIGGER,
     CameraMetadata.CONTROL_AF_TRIGGER_CANCEL);
     mCameraCaptureSession.capture(mPreviewCaptureRequestBuilder.build(),
     mSessionCaptureCallback, mBackgroundHandler);

但是面对一个错误告诉我

有人知道如何在没有自动对焦的情况下支持camera2 api中的这些设备吗？

错误出现在带有空位图的组合位图中。这似乎与自动对焦没有任何关系。您的权利，这是最经常发生的，因为我使用java在拍摄照片后缝合/合并图像，并且发生了此错误，我仍在处理此问题，但还不稳定，但另一个问题是如何支持没有自动对焦的设备
