调用相机，拍照但未通过＆＃39;保存＆＃39;

标签： android android-intent camera

下面的代码是一个包含2个按钮和imageview的活动。我打开相机意图，相机打开，我拍照并选择确认按钮＆＃39;在原生相机应用程序。

点击＆＃39;确认＆＃39; /＆＃39;保存＆＃39;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，或者我是如何追踪这个问题的？我可以在这里提交任何日志，除了相机应用程序界面中的那个，我看不到任何错误。

它是否是存储权限，我认为相机正试图存储点o＆＃39; save＆＃39;那就崩溃了。

public class NewUser_Activity extends Activity {

LogCat在相机失败后重新输入代码的位置......

答案 1 :(得分：0)

以下是; camera.putExtra("crop", "true");

Android工作室真的很烦人，它不会将应用程序中的代码跟踪到相机应用程序，因此您无法看到它，这是猜测工作。

如果这不起作用我该如何裁剪？
