Searching private key backups for non-Gmail accounts

[DenBond7]

Need to do add a fix for searching the private key backups for non-Gmail accounts.

Now we have the next template:

from:user@gmail.com
to:user@gmail.com
(subject:"Your CryptUp Backup"
 OR subject: "Your FlowCrypt Backup" 
 OR subject: "Your CryptUP Backup" 
 OR subject: "All you need to know about CryptUP (contains a backup)" 
 OR subject: "CryptUP Account Backup")
 -is:spam

And this search String works only for Gmail. Need to modify an algorithm using standard JavaMail API for non-Gmail accounts.

Unfortunately it's still failing for two of my friends. It just won't find any backups although it can find the backups on desktop.

I did some tests before (gmail search) on their accounts (I sent them a test apk) and the Gmail search was returning zero results, although the same gmail search pasted into Gmail webmail returned correct results. There is something weird with their IMAP - we need to debug it.

Let's make a test APK for them (separate branch) that will, instead of the load backup screen on setup, show debugging information.

We want to see number of search results for each of the following queries:

1. from: tom@cryptup.org
2. subject: "Your CryptUp Backup"
3. subject: "Your FlowCrypt Backup"
4. subject: "Your CryptUP Backup"
5. subject: "All you need to know about CryptUP (contains a backup)"
6. subject: "CryptUP Account Backup"
7. from: useremailaddress@gmail.com
8. to: useremailaddress@gmail.com

These are 8 different separate queries for us to find out which ones fail / which ones have some results. So the screen will show:

Test 1: 4 results
Test 2: 0 results
...
Test 8: 1 results

If we find out that all show 0 results, we can submit a bug to Google. If some show 0 results, maybe we can adjust the search query.

0d760b6 and 59b8f86 contain changes for the debug APK build. I created two options

1. https://github.com/FlowCrypt/flowcrypt-android/commits/issue_105_native_search - This example of native JavaMail API usage (I mean clear IMAP).

2. https://github.com/FlowCrypt/flowcrypt-android/commits/isssue_105_gmail_search - This example of GMAIL X-GM-RAW usage.

For me, both of this options give equivalent result.

Perfect, I'll have them test it.

@DenBond7 I think we found it. The debug screen was very helpful. It does not search archived email in either case! :)

Please archive your backup in Gmail and try.
