1. Set Block gallery to Off.

2. Get the Gallery package ID for devices. Some examples:

• LG Nexus 5:
  com.google.android.gallery3d, com.google.android.apps.photos
• Samsung Galaxy Note 3:
  com.sec.android.gallery3d, com.sec.android.gallery3d.panorama360view, com.google.android.apps.photos
• Sony Expire:
  com.sonyericsson.album, com.google.android.apps.photos
• HTC:
  com.google.android.apps.photos, com.htc.album
• Huawei:
  com.android.gallery3d, com.google.android.apps.photos

3. Make the hidden policy InboundDocumentExchangeWhitelist visible:

• Download the WorxMail APK file and wrap the file with the MDX Toolkit.
• Find the .mdx file on your computer and change the file suffix to .zip.
• Open the .zip file and find the policy_metadata.xml file
• Search for and change InboundDocumentExchangeWhitelist from <PolicyHidden>true</PolicyHidden> to <PolicyHidden>false</PolicyHidden>.
• Save the policy_metadata.xml file.
• Select all the files in that folder and compress to create the .zip file.
  Note: Don't zip the outer folder. Select all files inside the folder and compress the selected files.
• Click on the resulting compressed file.
• Choose Get Info and change the file suffix back to .mdx

4. Upload the modified .mdx file to the XenMobile console and add the list of Gallery package IDs to the now-visible Inbound document exchange whitelist policy.

Ensure that the package IDs are comma-separated:

com.sec.android.gallery3d, com.sec.android.gallery3d.panorama360view, com.google.android.apps.photos

5. Save and deploy Secure Mail.

Android users can now attach an image from the Gallery app.
