释放摄像头资源时导致手机重启-华为开发者话题

如题;
具体情况是  : 前置摄像头切换到后置摄像头然后释放资源,就会导致手机重启.必现
其他手机暂时没有出现这种情况;
释放资源的代码:
// 释放摄像有关的资源
private void closeCamera() {
if (camera != null) {
surfaceHolder.setKeepScreenOn(false);
surfaceHolder.removeCallback(this);
camera.setPreviewCallback(null);
camera.addCallbackBuffer(null);
camera.stopPreview();
camera.release();
camera = null;
}
}

每次切换摄像头都会调用这段代码.然后重新初始化摄像头.

这里好像是c的log
