Try below step once, I think it will help you.
1. Define a provider authority in your app’s AndroidManifest.xml file
<application>
...
<provider
android:name="androidx.core.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/file_paths" />
</provider>
...
In the above example, the authority “com.example.fileprovider” is used. You can replace this with your own unique authority.
2. Create a file_paths.xml file in your app’s res/xml folder to define the file paths that can be accessed by the file provider
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="export" path="export/" />
In the above example, the “export” folder under the app’s private files directory is defined as a path that can be accessed by the file provider.
3. Use the FileProvider.getUriForFile() method to get a content URI for the CSV file
val csvFile = File(getExternalFilesDir(null), "example.csv")
val fileUri = FileProvider.getUriForFile(
applicationContext,
"com.example.fileprovider",
csvFile
)
In the above example, the CSV file is stored in the app’s external files directory. You can replace this with your own file path.
4. Use the obtained URI to save the CSV file
try {
val outputStream = contentResolver.openOutputStream(fileUri)
outputStream?.use { outputStream ->
outputStream.write(csvData.toByteArray())
}
} catch (e: IOException) {
// Handle the exception
}
