For only sharing file you do not need `WRITE_EXTERNAL_STORAGE` permission .. Just save your file to cache dir by using `getCacheDir()`.. See [This](https://stackoverflow.com/a/35285667/4168607). — ADM, Aug 02 '19 at 03:53
You are trying to "Share" it. Do you mean save it to storage? Are you getting permission dialog? — Richard Dapice, Aug 02 '19 at 03:56
I have attached listener to a button, as soon as I click on the button the app crashes — Neeraj Butola, Aug 02 '19 at 04:01

If you are targeting Android API 24 or higher, private File URI resources (file:///) cannot be shared. We must instead wrap the File object as a content provider (content://) using the FileProvider

Declare your FileProvider in AndroidManifest.xml

<application>

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

</application>

Create fileprovider.xml inside res/xml folder

<?xml version="1.0" encoding="utf-8"?>
<paths>

    <external-path name="images" path="Downloads" />

</paths>

Get the Uri for the image file

Uri imageUri = getUriForFile(getContext(), "com.example.fileprovider", imageFile);

Use this Uri to share the image outside your app. For more details follow the link above. And also to share the image in your external storage you need to get file READ/WRITE permissions.

You can use this code for getting Uri from File

val imgUri =FileProvider.getUriForFile(it, "${activity.packageName}.file_provider", file)

In Android manifest for AndroidX

    <application>
      .....
        <provider
          android:name="androidx.core.content.FileProvider"
          android:authorities="${applicationId}.file_provider"
          android:exported="false"
          android:grantUriPermissions="true">
            <meta-data
              android:name="android.support.FILE_PROVIDER_PATHS"
              android:resource="@xml/provider_paths" />
        </provider>
      .....
    </application>

Create an XML path depends on your file path

<?xml version="1.0" encoding="utf-8"?>
<paths>
  <external-files-path
    name="files"
    path="/" />
  <external-path
    name="external_files"
    path="." />
</paths>
