此屏幕上发生的事情是，用户应该捕获一个屏幕截图.我保存此屏幕截图，并稍后在ImageView上显示.我通过URI检索屏幕截图图像.

What's happening at this screen is, The user is supposed to capture a screen-shot. I save this screen-shot and display it later on an ImageView. I retrieve the screen-shot image by it's URI.

当我使用图像的URI 检索图像时，发生崩溃.

The crash is happening when I am retrieving the image using it's URI.

1. App Compile SDK版本:28
2. App Target SDK版本:28

推荐答案

将文件提供程序用于图像URI.

Use File provider for Image URI.

尝试此代码:

添加代码AndroidManifest.xml

<application>
  <provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.mypackage.myprovider"
    android:exported="false"
    android:grantUriPermissions="true">
   <meta-data
     android:name="android.support.FILE_PROVIDER_PATHS"
     android:resource="@xml/provider_paths"/>
  </provider>
</application>

在res下的xml文件夹中添加provider_paths.xml文件.

<paths xmlns:android="http://schemas.android.com/apk/res/android">
   <external-path name="external_files" path="."/>
</paths>

从活动类的底部代码获取uri.

final Uri data = FileProvider.getUriForFile(context, "myprovider", new File(file_path)); //here your image uri
