Overview

Check out our new mobile database ObjectBox (GitHub repo).

ObjectBox is a superfast object-oriented database with strong relation support. ObjectBox is embedded into your Android, Linux, macOS, or Windows app.

greenDAO

greenDAO is a light & fast ORM for Android that maps objects to SQLite databases. Being highly optimized for Android, greenDAO offers great performance and consumes minimal memory.

Home page, documentation, and support links: https://greenrobot.org/greendao/

Features

greenDAO's unique set of features:

Rock solid: greenDAO has been around since 2011 and is used by countless famous apps
Super simple: concise and straight-forward API, in V3 with annotations
Small: The library is <150K and it's just plain Java jar (no CPU dependent native parts)
Fast: Probably the fastest ORM for Android, driven by intelligent code generation
Safe and expressive query API: QueryBuilder uses property constants to avoid typos
Powerful joins: query across entities and even chain joins for complex relations
Flexible property types: use custom classes or enums to represent data in your entity
Encryption: supports SQLCipher encrypted databases

Add greenDAO to your project

greenDAO is available on Maven Central. Please ensure that you are using the latest versions of the greendao and greendao-gradle-plugin artifact.

Add the following Gradle configuration to your Android project. In your root build.gradle file:

buildscript {
    repositories {
        jcenter()
        mavenCentral() // add repository
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3'
        classpath 'org.greenrobot:greendao-gradle-plugin:3.3.0' // add plugin
    }
}

In your app modules app/build.gradle file:

apply plugin: 'com.android.application'
apply plugin: 'org.greenrobot.greendao' // apply plugin
 
dependencies {
    implementation 'org.greenrobot:greendao:3.3.0' // add library
}

Note that this hooks up the greenDAO Gradle plugin to your build process. When you build your project, it generates classes like DaoMaster, DaoSession and DAOs.

Continue at the Getting Started page.

R8, ProGuard

If your project uses R8 or ProGuard add the following rules:

-keepclassmembers class * extends org.greenrobot.greendao.AbstractDao {
public static java.lang.String TABLENAME;
}
-keep class **$Properties { *; }

# If you DO use SQLCipher:
-keep class org.greenrobot.greendao.database.SqlCipherEncryptedHelper { *; }

# If you do NOT use SQLCipher:
-dontwarn net.sqlcipher.database.**
# If you do NOT use RxJava:
-dontwarn rx.**

Avoid EncryptedHelper ART warning due to missing SQLCipher super class

Today I've updated to version 3.1.1

When I launch the app, I make a request and pass the data to db. Since the new update I watch this warning, is it normal? Excuse for my english

Generated files like DaoMaster can not be referenced

I cannot import greenDAO 3 in my code for some reason. I have included it in my build.gradle and used gradle sync, but still it doesn't work.

I used the code from the example project.

import android.app.Application;

import org.greenrobot.greendao.database.Database;

public class App extends Application {
    /** A flag to show how easily you can switch from standard SQLite to the encrypted SQLCipher. */
    public static final boolean ENCRYPTED = true;

    private DaoSession daoSession;

    @Override
    public void onCreate() {
        super.onCreate();

        DevOpenHelper helper = new DevOpenHelper(this, ENCRYPTED ? "notes-db-encrypted" : "notes-db");
        Database db = ENCRYPTED ? helper.getEncryptedWritableDb("super-secret") : helper.getWritableDb();
        daoSession = new DaoMaster(db).newSession();
    }

    public DaoSession getDaoSession() {
        return daoSession;
    }
}

Rx support
While pragmatic programmers often do database operations on the main thread, some prefer strictly asynchronous operations. While greenDAO offers the latter, we should also have direct Rx support in the Android API.

Let's brainstorm on this:

Query could return an observable

Functions like loadAll could also be Rxified. Naming? loadAllRx? -> RxDao class

For update/delete/insert operations we could provide an observable transaction

Dependency should be compile-only, so Rx is completely optional

Future work (post V3.1):

Notifications and updatable observables

SQLiteDatabaseLockedException: database is locked (code 5)

Some of my users are facing SQLiteDatabaseLockedException.

I am using this code in my application class onCreate method to setup database:

private void setupDatabase() {
        DbUpdateHelper helper = new DbUpdateHelper(this, "app-name-db", null);
        SQLiteDatabase db = helper.getWritableDatabase();
        DaoMaster daoMaster = new DaoMaster(db);
        daoSession = daoMaster.newSession();
    }

This is the only place where I am accessing the db using helper.getWritableDatabase().

Everywhere else I am using the daoSession object to access db.

Crash on checkThread()

After some investigation of a crash we are seeing in our app, we would like to share some information.

The stacktrace is the following:

de.greenrobot.dao.DaoException: Method may be called only in owner thread, use forCurrentThread to get an instance for this thread at de.greenrobot.dao.query.AbstractQuery.checkThread(SourceFile:80) at de.greenrobot.dao.query.AbstractQuery.setParameter(SourceFile:70) at de.greenrobot.dao.query.AbstractQueryWithLimit.setParameter(SourceFile:48) at de.greenrobot.dao.query.Query.setParameter(SourceFile:30) setParameter setParameter

This is happening mostly on RIM devices. AbstractQueryData's forCurrentThread() is using Process.myTid() and this method might return 0. There was an attempt to fix this problem in https://github.com/greenrobot/greenDAO/issues/171 and the ticket was closed saying it was fixed with https://github.com/greenrobot/greenDAO/commit/013af9c4c4ee76af304b3b35f50588a7e6d68f63

While that fix might have worked for Robolectric, the issue mentioned by @dcowley is real and it is still there.

Can this be revised?

Improve GRADLE build Performance

Parallel builds. This project contains multiple modules. Parallel builds can improve the build speed by executing tasks in parallel. We can enable this feature by setting org.gradle.parallel=true.

Configuration on demand. Configuration on demand tells Gradle to configure modules that only are relevant to the requested tasks instead of configuring all of them. We can enable this feature by setting org.gradle.configureondemand=true.

gradle caching. Shared caches can reduce the number of tasks you need to execute by reusing outputs already generated elsewhere. This can significantly decrease build times. We can enable this feature by setting org.gradle.caching=true.
