Java android 安全异常

Question

在我的应用程序中，用户可以拍照或将照片添加到应用程序中。 当应用程序尝试在 ImageView 中显示保存的图像时，我收到 java.lang.SecurityException 的崩溃报告

出错的行是

holder.imageV.setImageURI(uriParsed);

我自己无法在我的设备或模拟器上复制该错误，它们都可以正常显示图像。

我正在使用的完整代码是

JoinProjectPicture projectPicture = mProjects.get(position);
Project current = projectPicture.getProject();
Picture picture = projectPicture.getPicture();

 holder.projectName.setText(current.getProjectName() + "(" + current.getWidth() + "x" + current.getHeight() + ")");
 holder.projectStatusTV.setText(current.getStatus());

 if(picture != null) {
      String pictureName = picture.getPictureName();
      Uri uriParsed = Uri.parse(pictureName);

      if(uriParsed != null) {
           Log.d("URIParsed", "Project: " + current.getProjectName() + " - Parsed: " + uriParsed);
           holder.imageV.setImageURI(uriParsed);
    }
}

我的设备上显示的日志输出(3 个项目，其中一个没有图像)

Project: Test - Parsed: file:///storage/emulated/0/Android/data/com.desbrina.diamondpaintinglogbook/files/Pictures/20191111_1408166491573472523237896.jpg

Answer 1

我认为您在 Android Pie 或更高版本的操作系统上遇到了安全异常。这是因为在这些系统上，您必须声明您的应用程序想要使用的路径。

请检查:https://developer.android.com/reference/android/support/v4/content/FileProvider

此外，您的应用可能正在尝试从另一个需要权限的应用获取内容，例如 Google 相册需要:<uses-permission android:name="com.google.android.apps.photos.permission.GOOGLE_PHOTOS"/>

检查这个:java.lang.SecurityException: Permission Denial: opening provider com.google.android.apps.photos.content.GooglePhotosImageProvider
