在我的应用程序中，用户可以拍照或向应用程序添加照片。当应用程序试图在java.lang.SecurityException中显示保存的图像时，我会收到ImageView的崩溃报告

它错误的行是

代码语言：javascript
复制
holder.imageV.setImageURI(uriParsed);

我无法在我的设备或模拟器上复制错误，它们都能很好地显示图像。

我使用的完整代码是

代码语言：javascript
复制
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);
    }
}

显示在我的设备上的日志的输出(3个项目，一个没有图像)

我想你是在Android Pie或更高版本的操作系统上获得了安全异常。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。

请查看：https://developer.android.com/reference/android/support/v4/content/FileProvider

此外，您的应用程序可能正在尝试从另一个需要使用Google所需权限的应用程序获取内容：<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

从Api 24，您不能直接访问文件Uris。您需要对文件夹使用文件授权，然后使用

代码语言：javascript
复制
val photoURI = FileProvider.getUriForFile(activity, BuildConfig.APPLICATION_ID + ".provider", File(path));

在AndroidManifes.xml中

将以下内容添加到application标记中。在下面的packagename是BuildConfig.APPLICATION_ID

代码语言：javascript
复制
<provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="packagename.provider"
            android:enabled="true"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths" />
        </provider>

provider_paths.xml

代码语言：javascript
复制
<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
        name="external"
        path="." />
</paths>

这种异常通常是由第三方使用imageuri引起的，app.Solution是用来实现文件的，provider.You可以得到很多关于如何实现文件提供者的解决方案。
