| 6 | <p>From a remote shell to your device or from your host machine, you can use the <a href= |
| 7 | "http://www.sqlite.org/sqlite.html">sqlite3</a> command-line program to manage SQLite databases |
| 8 | created by Android applications. The <code>sqlite3</code> tool includes many useful commands, |
| 9 | such as <code>.dump</code> to print out the contents of a table and <code>.schema</code> to print |
| 10 | the SQL CREATE statement for an existing table. The tool also gives you the ability to execute |
| 11 | SQLite commands on the fly.</p> |
| 12 | |
| 13 | <p>To use <code>sqlite3</code> from a remote shell:</p> |
| 14 | |
| 15 | <ol> |
| 16 | <li>Enter a remote shell by entering the following command: |
| 17 | <pre>adb [-d|-e|-s {<serialNumber>}] shell</pre> |
| 18 | </li> |
| 19 | |
| 20 | <li>From a remote shell, start the <code>sqlite3</code> tool by entering the following command: |
| 21 | <pre>sqlite3</pre> |
| 22 | |
| 23 | <p>You can also optionally specify a full path to a database that you want to explore. |
| 24 | Emulator/device instances store SQLite3 databases in the directory |
| 25 | <code>/data/data/<package_name>/databases/</code>.</p> |
| 26 | </li> |
| 27 | |
| 28 | <li>Once you invoke <code>sqlite3</code>, you can issue <code>sqlite3</code> commands in the |
| 29 | shell. To exit and return to the adb remote shell, enter <code>exit</code> or press |
| 30 | <code>CTRL+D</code>.</li> |
| 31 | </ol> |
| 32 | |
| 33 | |
| 34 | <p>Here's an example:</p> |
| 35 | <pre>$ adb -s emulator-5554 shell |
| 36 | # sqlite3 /data/data/com.example.google.rss.rssexample/databases/rssitems.db |
| 37 | SQLite version 3.3.12 |
| 38 | Enter ".help" for instructions |
| 39 | <em>.... enter commands, then quit...</em> |
| 40 | # sqlite> .exit |
| 41 | </pre> |
| 42 | |
| 43 | <p>To use <code>sqlite3</code> locally, instead of within a shell, |
| 44 | pull the database file from the device and start {@code sqlite3}:</p> |
| 45 | |
| 46 | <ol> |
| 47 | <li>Copy a database file from your device to your host machine: |
| 48 | <pre> |
| 49 | adb pull <database-file-on-device> |
| 50 | </pre> |
| 51 | </li> |
| 52 | |
| 53 | <li>Start the sqlite3 tool from the <code>/tools</code> directory, specifying the database |
| 54 | file: |
| 55 | <pre> |
| 56 | sqlite3 <database-file-on-host> |
| 57 | </pre> |
| 58 | </li> |
| 59 | </ol> |
