Automatically backing up SQLite database

Question

My app uses a small SQLite database that I'd like to have backed up. I'm assuming this won't happen automatically, without my coding for it using fullBackupContent, shown below. How do I modify the content of my backupscheme.xml to set the include path correctly? I prefer to set the db location at runtime.

My backupscheme.xml looks like

<?xml version="1.0" encoding="utf-8"?>
<full-backup-content >
    <include domain="database" path="device_info.db"/>
</full-backup-content

My manifest contains:

    <application
    android:allowBackup="true"
    android:icon="@drawable/time_machine_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" 
    android:name="mypackage.myapp"
    android:fullBackupContent="@xml/backupscheme"

Answer 1

<include domain="database" path="device_info.db"/>

Here, the domain indicates the root directory in which the path is interpreted. database maps to where SQLite databases are stored by default, if you use:

• getDatabasePath() on Context
• SQLiteOpenHelper with just a plain filename
• openOrCreateDatabase() with just a plain filename

In that case, the filename should be your path value.

If your database is stored somewhere else for some reason, the <include> directive would need some adjustment.
