setParameters失败的Nexus 5和Nexus 7 [英] setParameters Failed in Nexus 5 and Nexus 7

问题描述

我在我的应用程序实现的自定义相机。它在所有的设备，除了Nexus 5和Nexus 7，做工精细在这两个设备，它与崩溃失败SetParameters相机。我已实施的自定义相机跌破code：

I have implemented custom camera in my app. It is working fine in all device except Nexus 5 and Nexus 7. In both devices, It is crashing with SetParameters failed on camera. I have implemented custom camera with below code:

public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
        if (mCamera != null) {
            Log.e(TAG, "surfaceChanged called");
            Camera.Parameters parameters = mCamera.getParameters();
            if (mSupportedPreviewSizes != null) {
                mPreviewSize = getOptimalPreviewSize(mSupportedPreviewSizes, w,
                        h);
            }
            Log.e(TAG, "surfaceChanged : mPreviewSize height:"
                    + mPreviewSize.height + " width: " + mPreviewSize.width);
            parameters.setPreviewSize(mPreviewSize.width, mPreviewSize.height);

            requestLayout();

            mCamera.setParameters(parameters);
            Log.e(TAG, "surfaceChanged called setParameters success");
        }
    }

我在很多地方发现评论说，这是由于不支持preVIEW大小，但就我而言，我已经从支持preVIEW大小服用。

I have found at many places comments that it is due to unsupported preview size but In my case, I am already taking it from supported preview sizes.

推荐答案

我有一台Nexus平板电脑相同的问题：在同一code更改preVIEW大小到另一个支持preVIEW大小制作各种平板电脑而不是平板电脑的Nexus我了。

I had the same issue with a Nexus tablet: the same code changing the preview size to another supported preview size worked on various tablets but not the nexus tablet I had.

在我的情况下，这个问题，我已经改变了preVIEW大小之前已经开始previewing。启动preVIEW大小解决了我的问题之前，改变preVIEW大小。

In my case, the issue was that I had already started previewing before changing the preview size. Changing the preview size before starting the preview size solved my issue.
