调用相机，拍照但“保存”失败答案

【问题标题】：call camera, take picture but fails on 'save'调用相机，拍照但“保存”失败
【发布时间】：2015-04-26 20:53:05
【问题描述】：

我下面的代码是一个带有 2 个按钮和一个图像视图的活动。我触发相机意图，相机打开，我拍照并在本机相机应用程序中选择“确认按钮”。

点击“确认”/“保存”时，相机崩溃，我的应用代码在onActivityResult 重新输入，我看到RESULT_OK 为-1。

有人知道可能是什么问题，或者我确实可以如何跟踪问题吗？我可以在此处提交的任何日志，除了相机应用程序屏幕中的错误，我看不到任何错误。

可能是存储权限吗，我假设相机正试图在“保存”点进行存储，那是它崩溃的时候。

【问题讨论】：

我对这个问题有点困惑，因为 RESULT_OK 是 -1，所以看起来相机应用程序没有崩溃，而是告诉你它结果正确。 logcat 有什么东西吗？
logcat 中我看不到任何内容。相机确实崩溃了-'相机已停止工作'。相机关闭，我们返回我的代码（我称之为相机意图），result_ok = -1

标签： android android-intent camera

【解决方案1】：

查看该帖子： Summary: Take a picture utilizing Camera Intent and display the photo with correct orientation (works on hopefully all devices)

在这里找到一些示例代码：https://github.com/ralfgehrer/AndroidCameraUtil

【讨论】：

您是否使用其他设备运行您的代码？根据我的经验，相机意图在所有制造商和 android 版本的所有 android 设备上的实施不一致。所以很难确定问题所在。因此，我在 github 上分享了我的解决方案以及经过测试的设备列表。随意尝试一下。
我发现问题就在那儿，以为我更新了这个线程，可能是错误地更新了另一个...... - camera.putExtra("crop", "true");让它崩溃。那是怎么回事？这是和 dev 的一个主要缺点，并且会认为它会被覆盖。我现在必须找到一种行之有效的裁剪方法

【解决方案2】：

是这样的； camera.putExtra("crop", "true");

Android Studio 真的很烦人，它不会将我的代码从应用程序跟踪到相机应用程序，所以你看不到它，这是猜测工作。

如果这不起作用，我该如何裁剪？
