DMAPP-156: Fix file download issue

[meKushdeepSingh]

Details:

• Added logic to check if a deleted file exists.
• Unlink the file before downloading the new file.

• It seems that the import statement for useState from 'react' is not being used in the code. You can remove it.
• The import path for Toaster and ToasterOptions seems incorrect. You might need to adjust the path according to the correct file structure.
• In the useFileDownload function, the conditional check for Android version in the permission request Platform.Version <= 28 might need further testing or validation.
• There is a comment mentioning "Public Downloads on Android" while defining the file path for Android, but the actual directory seems to be '/storage/emulated/0/Download'. It would be good to update the comment for clarity.
• There is a typo in the comment in the function handleIOSDownload, it should be "file saved" instead of "File Saved".
• The error handling in the handleIOSDownload function could be improved by showing the error message to the user or handling it differently.
• It's recommended to add more descriptive error messages or logging in the catch block of the saveBase64File function to provide better context in case of failures.

All looks good.

In the AndroidManifest.xml file:

1. The package name should not have 'android.' prefix. So instead of android.permission.INTERNET, it should be android.permission.INTERNET.
2. In the <uses-permission> tag for WRITE_EXTERNAL_STORAGE, the android:maxSdkVersion should be defined without space between '=' and '28'. So, it should be android:maxSdkVersion="28".
3. The <intent> section inside <queries> should use <intent-filter> instead of <queries>.

In the code file:

1. Check the import statement in line 69. There is no need to include the JavaScript code inside the AndroidManifest file.
2. Check the import for React in line 2, it should be imported correctly as import React from 'react';.
3. In the requestStoragePermission function, the condition for checking Android version should be Platform.Version < 28 instead of Platform.Version <= 28.
4. In the Share.share method, the check should be if (res.action === 'sharedAction' && res.activityType === 'com.apple.UIKit.activity.SaveToCameraRoll') instead of 'com.apple.DocumentManagerUICore.SaveToFiles'.
5. In the import statements for React Native components, make sure all the paths are correct and exist in the project.

All looks good.
