All the files in this directory are copied from stock android. The following
files:
JniConstants.cpp
JNIHelp.cpp
ALog-priv.h
are copied in from Android's libnativehelper module (altogether less than 1000
lines of code). The remainder are from the core framework (directory
/frameworks/base/core/jni).
Notes on changes:
The ashmem_XXX() interfaces are used for the various "xxxForBlobDescriptor()"
API functions. The code in libcutils for this seems to be platform
dependent - some platforms have kernel support, others have a user space
implementation. So these functions are not supported for now.
The original SQLiteConnection.cpp uses AndroidRuntime::genJNIEnv() to obtain a
pointer to the current threads environment. Changed to store a pointer to the
process JavaVM (Android allows only one) as a global variable. Then retrieve
the JNIEnv as needed using GetEnv().
Replaced uses of class String8 with std::string in SQLiteConnection.cpp and a
few other places.
The stock Android code to populate CursorWindow containers with the results of
a SELECT statement uses a C++ interface that is not available to NDK builds. So
this code is rewritten to call the CursorWindow java interface via JNI methods.
This is the largest source code change. See function
nativeExecuteForCursorWindow() in file android_database_SQLiteConnection.cpp
for details.
The "LOCALIZED" collation and some miscellaneous user-functions added by the
sqlite3_android.cpp module are not included. A collation called LOCALIZED
that is equivalent to BINARY is added instead to keep various things working.
This should not cause serious problems - class SQLiteConnection always
runs "REINDEX LOCALIZED" immediately after opening a connection.

/**
* A cache to avoid calling FindClass at runtime.
*
* Class lookup is relatively expensive (2.5us on passion-eng at the time of writing), so we do
* all such lookups eagerly at startup. This means that code that never uses, say,
* java.util.zip.Deflater still has to pay for the lookup, but it means that on a device the cost
* is definitely paid during boot and amortized. A central cache also removes the temptation to
* dynamically call FindClass rather than add a small cache to each file that needs one. Another
* cost is that each class cached here requires a global reference, though in practice we save
* enough by not having a global reference for each file that uses a class such as java.lang.String
* which is used in several files.
*
* FindClass is still called in a couple of situations: when throwing exceptions, and in some of
* the serialization code. The former is clearly not a performance case, and we're currently
* assuming that neither is the latter.
*
* TODO: similar arguments hold for field and method IDs; we should cache them centrally too.

/**
* CloseGuard is a mechanism for flagging implicit finalizer cleanup of
* resources that should have been cleaned up by explicit close
* methods (aka "explicit termination methods" in Effective Java).
* <p>
* A simple example: <pre> {@code
* class Foo {
*
* private final CloseGuard guard = CloseGuard.get();
*
* ...
*
* public Foo() {
* ...;
* guard.open("cleanup");
* }
*
* public void cleanup() {
* guard.close();
* ...;
* }
*
* protected void finalize() throws Throwable {
* try {
* if (guard != null) {
* guard.warnIfOpen();
* }
* cleanup();
* } finally {
* super.finalize();
* }
* }
* }
* }</pre>
*
* In usage where the resource to be explicitly cleaned up are
* allocated after object construction, CloseGuard protection can
* be deferred. For example: <pre> {@code
* class Bar {
*
* private final CloseGuard guard = CloseGuard.get();
*
* ...
*
* public Bar() {
* ...;
* }
*
* public void connect() {
* ...;
* guard.open("cleanup");
* }
*
* public void cleanup() {
* guard.close();
* ...;

* try {
* if (guard != null) {
* guard.warnIfOpen();
* }
* cleanup();
* } finally {
* super.finalize();
* }
* }
* }
* }</pre>
*
* When used in a constructor calls to {@code open} should occur at
* the end of the constructor since an exception that would cause
* abrupt termination of the constructor will mean that the user will
* not have a reference to the object to cleanup explicitly. When used
* in a method, the call to {@code open} should occur just after
* resource acquisition.
*
* <p>
*
* Note that the null check on {@code guard} in the finalizer is to
* cover cases where a constructor throws an exception causing the
* {@code guard} to be uninitialized.

/**
* Provides a single client the ability to use a database.
*
* <h2>About database sessions</h2>
* <p>
* Database access is always performed using a session. The session
* manages the lifecycle of transactions and database connections.
* </p><p>
* Sessions can be used to perform both read-only and read-write operations.
* There is some advantage to knowing when a session is being used for
* read-only purposes because the connection pool can optimize the use
* of the available connections to permit multiple read-only operations
* to execute in parallel whereas read-write operations may need to be serialized.
* </p><p>
* When <em>Write Ahead Logging (WAL)</em> is enabled, the database can
* execute simultaneous read-only and read-write transactions, provided that
* at most one read-write transaction is performed at a time. When WAL is not
* enabled, read-only transactions can execute in parallel but read-write
* transactions are mutually exclusive.
* </p>
*
* <h2>Ownership and concurrency guarantees</h2>
* <p>
* Session objects are not thread-safe. In fact, session objects are thread-bound.
* The {@link SQLiteDatabase} uses a thread-local variable to associate a session
* with each thread for the use of that thread alone. Consequently, each thread
* has its own session object and therefore its own transaction state independent
* of other threads.
* </p><p>
* A thread has at most one session per database. This constraint ensures that
* a thread can never use more than one database connection at a time for a
* given database. As the number of available database connections is limited,
* if a single thread tried to acquire multiple connections for the same database
* at the same time, it might deadlock. Therefore we allow there to be only
* one session (so, at most one connection) per thread per database.
* </p>
*
* <h2>Transactions</h2>
* <p>
* There are two kinds of transaction: implicit transactions and explicit
* transactions.
* </p><p>
* An implicit transaction is created whenever a database operation is requested
* and there is no explicit transaction currently in progress. An implicit transaction
* only lasts for the duration of the database operation in question and then it
* is ended. If the database operation was successful, then its changes are committed.
* </p><p>
* An explicit transaction is started by calling {@link #beginTransaction} and
* specifying the desired transaction mode. Once an explicit transaction has begun,
* all subsequent database operations will be performed as part of that transaction.
* To end an explicit transaction, first call {@link #setTransactionSuccessful} if the
* transaction was successful, then call {@link #end}. If the transaction was
* marked successful, its changes will be committed, otherwise they will be rolled back.
* </p><p>
* Explicit transactions can also be nested. A nested explicit transaction is
* started with {@link #beginTransaction}, marked successful with
* {@link #setTransactionSuccessful}and ended with {@link #endTransaction}.
* If any nested transaction is not marked successful, then the entire transaction
* including all of its nested transactions will be rolled back
* when the outermost transaction is ended.
* </p><p>
* To improve concurrency, an explicit transaction can be yielded by calling
* {@link #yieldTransaction}. If there is contention for use of the database,
* then yielding ends the current transaction, commits its changes, releases the
* database connection for use by another session for a little while, and starts a
* new transaction with the same properties as the original one.
* Changes committed by {@link #yieldTransaction} cannot be rolled back.
* </p><p>
* When a transaction is started, the client can provide a {@link SQLiteTransactionListener}
* to listen for notifications of transaction-related events.
* </p><p>
* Recommended usage:
* <code><pre>
* // First, begin the transaction.
* session.beginTransaction(SQLiteSession.TRANSACTION_MODE_DEFERRED, 0);
* try {
* // Then do stuff...
* session.execute("INSERT INTO ...", null, 0);
*
* // As the very last step before ending the transaction, mark it successful.
* session.setTransactionSuccessful();
* } finally {
* // Finally, end the transaction.
* // This statement will commit the transaction if it was marked successful or
* // roll it back otherwise.
* session.endTransaction();
* }
* </pre></code>
* </p>
*
* <h2>Database connections</h2>
* <p>
* A {@link SQLiteDatabase} can have multiple active sessions at the same
* time. Each session acquires and releases connections to the database
* as needed to perform each requested database transaction. If all connections
* are in use, then database transactions on some sessions will block until a
* connection becomes available.
* </p><p>
* The session acquires a single database connection only for the duration
* of a single (implicit or explicit) database transaction, then releases it.
* This characteristic allows a small pool of database connections to be shared
* efficiently by multiple sessions as long as they are not all trying to perform
* database transactions at the same time.
* </p>
*
* <h2>Responsiveness</h2>
* <p>
* Because there are a limited number of database connections and the session holds
* a database connection for the entire duration of a database transaction,
* it is important to keep transactions short. This is especially important
* for read-write transactions since they may block other transactions
* from executing. Consider calling {@link #yieldTransaction} periodically
* during long-running transactions.
* </p><p>
* Another important consideration is that transactions that take too long to
* run may cause the application UI to become unresponsive. Even if the transaction
* is executed in a background thread, the user will get bored and
* frustrated if the application shows no data for several seconds while
* a transaction runs.
* </p><p>
* Guidelines:
* <ul>
* <li>Do not perform database transactions on the UI thread.</li>
* <li>Keep database transactions as short as possible.</li>
* <li>Simple queries often run faster than complex queries.</li>
* <li>Measure the performance of your database transactions.</li>
* <li>Consider what will happen when the size of the data set grows.
* A query that works well on 100 rows may struggle with 10,000.</li>
* </ul>
*
* <h2>Reentrance</h2>
* <p>
* This class must tolerate reentrant execution of SQLite operations because
* triggers may call custom SQLite functions that perform additional queries.

<h1>
SQLite Android Bindings
</h1>
<p> The SQLite library is a core part of the Android environment. Java
applications and content providers access SQLite using the interface in
the
<a href="http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html">android.database.sqlite</a> namespace.
<p> One disadvantage of using Android's built-in SQLite support is that the
application is forced to use the version of SQLite that the current version of
Android happened to ship with. If your application happens to require a newer
version of SQLite, or a build with a custom extension or
<a href=http://www.sqlite.org/vfs.html>VFS</a> installed, you're out of luck.
<p>The code in this project allows an application to use the
<a href=http://developer.android.com/tools/sdk/ndk/index.html>Android NDK</a>
to build a custom version of SQLite to be shipped with the application while
still continuing to use the standard Java interface.
<h2>Normal Usage</h2>
<h3>Installation</h3>
<p>
Android API levels 15 (Android 4.0.3) and greater are supported. If
targetting API level 16 or greater, use the default "trunk" branch of this
project. Or, for API level 15, use the "api-level-15" branch. It is not possible
to target an API level lower than 15.
<p>
Copy the following files from this project into the equivalent locations in
the application project.
<pre>
jni/Android.mk
jni/Application.mk
jni/sqlite/* (copy contents of directory recursively)
src/org/sqlite/database/* (copy contents of directory recursively)
</pre>
<p>
Following this, the directory structures should contain
[/tree?ci=trunk&re=%5ejni%7csrc/org/sqlite/data&expand | these files].
<p>
For API level 15 only, also copy the following:
<pre>
src/org/sqlite/os/* (copy contents of directory recursively)
</pre>
<p>
Directory "jni/sqlite/" contains copies of the sqlite3.h and sqlite3.c
source files. Between them, they contain the
<a href=http://www.sqlite.org/amalgamation.html>source code for the SQLite
library</a>. If necessary, replace these with the source for the specific
version of SQLite required. If SQLite is to be compiled with any special
pre-processor macros defined, add them to the "jni/sqlite/Android.mk" file
(not jni/Android.mk).
<p>
Once the files have been added to the project, run the command "ndk-build"
in the root directory of the project. This compiles the native code in
the jni/ directory (including the custom SQLite version) to shared libraries
that will be deployed to the device along with the application. Assuming
it is successful, unless you modify the sources or makefiles within the
jni/ directory structure, you should not need to run "ndk-build" again.
<h3>Application Programming</h3>
<p>
Before using any SQLite related methods or objects, the shared library
compiled using the ndk must be loaded into the application using the
following code:
<verbatim>
System.loadLibrary("sqliteX");
</verbatim>
<p>
One way to ensure that the shared library is loaded early enough is
to add it to a "static" block within the declaration of the application's
main Activity class.
<p>
The classes that make up the built-in Android SQLite interface reside in
the "android.database.sqlite" namespace. This interface provides all of
the same classes, except within the "org.sqlite.database.sqlite" namespace.
This means that to modify an application to use the custom version of
SQLite, all that is usually required is to replace all occurrences
"android.database.sqlite" within the source code with
"org.sqlite.database.sqlite". For example, the following:
<verbatim>
import android.database.sqlite.SQLiteDatabase;
</verbatim>
<p>should be replaced with:
<verbatim>
import org.sqlite.database.sqlite.SQLiteDatabase;
</verbatim>
<p>
As well as replacing all uses of the classes in the
android.database.sqlite.* namespace, the application must also be sure
to use the following two:
<verbatim>
org.sqlite.database.SQLException
org.sqlite.database.DatabaseErrorHandler
</verbatim>
<p>instead of:
<verbatim>
android.database.SQLException
android.database.DatabaseErrorHandler
</verbatim>
<p>Aside from namespace changes, there are other differences from the
stock Android interface that applications need to be aware of:
<ol>
<li> The SQLiteStatement.<a href="http://developer.android.com/reference/android/database/sqlite/SQLiteStatement.html#simpleQueryForBlobFileDescriptor()">simpleQueryForBlobFileDescriptor()</a>
API is not available.
<li> The collation sequence "UNICODE" is not available.
<li> The collation sequence "LOCALIZED", which normally changes with the
system's current locale, is always equivalent to SQLite's built
in collation BINARY.
</ol>
<h2>Using The SQLite Encryption Extension</h2>
<p>
To use the <a href=http://www.sqlite.org/see/doc/trunk/www/readme.wiki>
SQLite Encryption Extension</a> (SEE) on Android, replace the sqlite3.c
file at "jni/sqlite/sqlite3.c" with a SEE-enabled version (i.e. the
concatenation of sqlite3.c and see.c - refer to the link above for
details). Next, open the file jni/sqlite/Android.mk and locate the
following two lines:
<verbatim>
# If using SEE, uncomment the following:
# LOCAL_CFLAGS += -DSQLITE_HAS_CODEC
</verbatim>
<p>
Uncomment the second of them, then run "ndk-build" as described above to
generate the shared libraries.
<p>
After opening or creating an encrypted database, the application must
immediately execute a PRAGMA to configure the encryption key. This must
be done before any other database methods are called. For example:
<verbatim>
import org.sqlite.database.sqlite.SQLiteDatabase;
...
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase("my.db", null);
db.execSQL("PRAGMA key = 'secretkey'");
</verbatim>
<p>
Or, if you are using the
<a href=http://developer.android.com/reference/android/database/sqlite/SQLiteOpenHelper.html>SQLiteOpenHelper</a>
helper class, the PRAGMA must be the first thing executed within the
onConfigure() callback. For example:
<verbatim>
import org.sqlite.database.sqlite.SQLiteDatabase;
import org.sqlite.database.sqlite.SQLiteHelper;
...
class MyHelper extends SQLiteOpenHelper {
...
void onConfigure(SQLiteDatabase db){
db.execSQL("PRAGMA key = 'secretkey'");
}
...
}
</verbatim>
<p>
Refer to the <a href=http://www.sqlite.org/see/doc/trunk/www/readme.wiki>
SEE documentation</a> for further details regarding encryption keys.
<p>Aside from supporting encrypted databases, SEE-enabled builds behave
differently in two more respects:
<ol>
<li> <p>The SQLiteDatabase.<a href="http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html#enableWriteAheadLogging()">enableWriteAheadLogging()</a> method does not enable
connection pooling. It is not possible for connection pooling to be
used with a SEE-enabled build (even if the database is unencrypted).
<li> <p>In Android, if database corruption is encountered, or if an attempt is
made to open a file that is not an SQLite database, the default
behaviour is to delete the file and create an empty database file in
its place. In a SEE-enabled build, the default behaviour is to throw
an exception.<br><br>
The reason for this is that supplying an incorrect encryption key
is indistinguishable from opening a file that is not a database file.
And it seems too dangerous to simply delete the file in this case.
<br><br>
The default behaviour can be overriden using the
<a href="http://developer.android.com/reference/android/database/DatabaseErrorHandler.html">DatabaseErrorHandler</a> interface.
</ol>
