groovy c:\Users\Alecxs\Downloads\AndroidEmailExtractor. WHERE messageKey = $” from line 85, or remove line 85 altogether to process all accounts and mailboxes – but note the caveats around shortcomings (the script was good enough to fulfil my need). """SELECT fileName, mimeType, size, contentId, contentUri, encoding The script does not handle attachments – this was a conscious decision as whilst the camera photos were in /f, the other ‘RAW’ attachments were not in /1.db_att/ as per the javadoc of the AttachmentProvider classĪs an initial hint, to reconstruct the attachments you would need to use MimeMultipart, create the MimeBodyPart objects starting with a query like: Body.textReply is separated from the Body.textContent with a separator line of 25 dashes it does not attempt to reconstruct the header information of the preceding message in the threadĥ. The body handling only uses plain text rather than alternative multipartsĤ. Addresses only use the address rather than the labelģ. It is set to default the Sender field rather than converting the value of omList and using the addFrom methodĢ. ShortcomingsĪs a first cut that was good enough for my purposes, there are a few deficiencies:ġ. Email Extractionīeing comfortable with the RFC822 specs & JavaMail (I built an IMAP extension for Alfresco in 2006), I decided it would be easier to reconstruct a MimeMessage using SQL & Groovy than attempt to adapt the Android source code to run off the device or build a custom app to run in the emulator. If you don’t want to limit the extraction to a single mailbox or account then you can remove the WHERE clause from the first SELECT query. SELECT a.displayName as accountName, m._id as mailboxKey, m.displayName as mailboxName You can browse the data or execute the following query to get a list of mailboxes and their corresponding accounts: The next step is to select Developer options from the System section of the settings list (Figure 1) and then enable USB debugging on the device (Figure 2). Executing ‘ adb usb‘ (re)starts the adbd daemon listening to USB connections. Backup with ADBĪDB is the Android Debug Bridge, a debugging tool that is part of the Android SDK platform tools. The source code is available from – in this case it was for a Samsung phone running 4.1.2 so I checked out the jb-mr0-release branch to inspect the code when required. The stock client stores message headers and their bodies in two sqlite databases and the AttachmentProvider stores attachments on disk. Purging is a last resort for cleaning up a table in the offline store, because it wipes all records from the cache and requires you to re-download them.Sometimes the Android ecosystem is a little lacking with tool support for instance I needed to extract a set of sent items from a POP3 mailbox – the stock mail client only allows you to perform 3 actions: delete, mark as unread or favourite.Īrmed with the Android SDK, some SQL queries and a Groovy script we’ll see how it’s possible to recover email to RFC822. You can push pending operations for all tables, a list of tables, or one table: // All tables Similarly, the local store is populated with new or updated data only when you pull data. Nothing is sent to the service until you push local changes. Your client code controls when local changes are synchronized with a data sync service. For example, use a version of SQLite with SQLCipher to produce an encrypted store. You can also implement your own local store. Most platforms use SQLite for the local store, but iOS uses Core Data. What is a local store?Ī local store is the data persistence layer on the client device. Before you perform any operations, you must initialize the local store. The local store can then be synchronized with the service at a later time. I need to export an SQLite database from an Android phone to a computer. A sync table (provided by IOfflineTable) provides the same operations against a local store. The operation fails if the device doesn't have a network connection. The Azure Mobile Apps SDKs provide IRemoteTable, which accesses the service directly. The following tutorials show how to add offline sync to your mobile clients by using Azure Mobile Apps: Limits network use on high-latency or metered networks.Improves app reliability when there's bad network connectivity.The SDK supports conflict resolution when the same record is changed on both the client and the service. Data is synchronized with your Azure Mobile Apps service when your device is online. When your app is offline, you can still create, modify, and search the data. Offline data sync is an SDK feature of Azure Mobile Apps.
