Android 4.2.2上的Android摄像头出现故障（API级别17）

我正在试着用相机，但它无法启动。hw.camera.back:Webcam（）hw.camera.front:Webcam（）不确定还要添加什么，因为我无法剪切和粘贴细节

我得到的错误是不幸的，相机停止了

我的代码如下，但它不是我的代码。当我尝试在不使用任何编程的情况下使用相机时，我会得到相同的错误

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(takePictureIntent, actionCode);

在日志中，我有以下内容。 我在LogCat中看到的一个我不理解的错误与我没有使用的电子邮件有关，我甚至不知道如何打开或关闭它。 D/ExchangeService（617）：！！！未找到电子邮件应用程序；停止自我
