Duplicate Message Counts

[midhunhk]

Sometimes, when opening the app after a message is sent, the count is not updated on app launch, but on relaunch the sent message count is doubled.

To Reproduce
Steps to reproduce the behavior:

1. Send one or more messages
2. Start the app via Widget or from Launcher
3. If the sent count is displayed as 0 or unchanged, this issue may occur
4. Click on Counter button or exit and launch app again
5. Double the unindexed message count is displayed

Expected behavior
There should not be duplicate counts.

Smartphone (please complete the following information):

• Device: Samsung Galaxy S9
• OS: Android 8.0
• Application Version 4.0.0

Multiple index message tasks may have been initiated could cause this issue.

Fixes applied

• Store an Index In Progress flag in Shared Preferences so that multiple indexes are not initiated
• Declare activity as singleInstance, so same Activity is reused when opening app from Launcher or Widget
