Version of SQLite used in Android?

What is the vers开发者_Python百科ion of SQLite used in Android?

Reason: I'm wondering how to handle schema migrations. The newer SQLite versions support an "ALTER TABLE" SQL command which would save me having to copy data, drop the table, recreate table and re-insert data.

Here is a link to the official docs which include the main points in this answer: android.database.sqlite package-level javadoc

Kotlin code to get framework SQLite version (tip: just stick a breakpoint in your Activity onCreate() and use this code in Evaluate Expression...):

val version = android.database.sqlite.SQLiteDatabase.create(null).use {
    android.database.DatabaseUtils.stringForQuery(it, "SELECT sqlite_version()", null)
}
"Framework (API ${android.os.Build.VERSION.SDK_INT}) SQLite version: $version".also { println(it) }

Using the emulators (note, SQLite version on actual devices will be at least that specified):

* Android API level links show where the android.database.sqlite package has changed. Where there is no link (e.g. API level 17), indicates no changes to that package.

** Broken SDK link, see here

Note: if you want your app to use the same version of SQLite across all Android versions, consider using Requery's 3rd party SQLite support library or SQLCipher (if you also want encryption).

Although the documentation gives 3.4.0 as reference number, if you execute the following sql, you'll notice that there is a much higher number of SQlite installed:

Cursor cursor = SQLiteDatabase.create(null).rawQuery("select sqlite_version() AS sqlite_version", null);
String sqliteVersion = "";
while(cursor.moveToNext()){
   sqliteVersion += cursor.getString(0);
}

This is just a piece of quick, dirty code to retrieve the sqlite version. For instance on a HTC Hero with Android 2.1, I get: 3.5.9.

On my Nexus One with Android 2.2, I even get 3.6.22.

$ adb shell sqlite3 --version 
3.5.9

Same on ADP1 1.6 & 2.1 emulator.

A short overview of the Andorid APIs and the supported SQLite versions.

The overview is from the link in Mark Carters answer.

In Room you can query

SELECT sqlite_version()
