Android-OrmLiteContentProvider

Overview

What's new

Ver1.0.4

Throw away the Maven, I adopted the Gradle build system. I suffer from these, spent a lot of time...
Extended the automatic generation of the Contract class. This makes it possible to output by integrating multiple classes.
Added the TABLE_NAME(table name) to Contract class to be generated.
Subdivided the internal processing. If you have to override the method, you will be able to intervene in the process some.

Ver1.0.2

This project has changed the license at the same time as published in Maven Central Repository. Changed the license to 'Apache License, Version 2.0' from 'ISC License'. By this, everyone will be easy to use!
Automatic generation of Contract Class. By Java annotation processing, to automatically generate it based on the table definition class.

Features

This is what can be done?

This is a library that easy to make using ContentProvider with OrmLite.
With this library, you can focus on the operation of the table.
You can from among the following three of the abstract class, select the inheritance class.

android.content.ContentProvider  
　　└ OrmLiteBaseContentProvider  
　　　└ OrmLiteDefaultContentProvider  
　　　　└ OrmLiteSimpleContentProvider

You can be used to match the level of your implementation.
You can focus on implementing the original function.

Getting Started

Implementing a Contract Class (Optional)

If you want to automatically generate, skip this step. When implemented compiler, this similar class is created.

See Android Developers : Implementing a Contract Class
You define the column name as a string. You are free to define it.

public class Contract
{
    public static final String DATABASE_NAME = "MyDatabase";
    public static final int DATABASE_VERSION = 1;

    public static final String AUTHORITY = "com.tojc.ormlite.android.ormlitecontentprovidersample";

    // accounts table info
    public static class Account implements BaseColumns
    {
        public static final String TABLE_NAME = "accounts";

        public static final String CONTENT_URI_PATH = TABLE_NAME;

        public static final String MIMETYPE_TYPE = TABLE_NAME;
        public static final String MIMETYPE_NAME = AUTHORITY + ".provider";

        // feild info
        public static final String NAME = "name";

        // content uri pattern code
        public static final int CONTENT_URI_PATTERN_MANY = 1;
        public static final int CONTENT_URI_PATTERN_ONE = 2;

        // Refer to activity.
        public static final Uri contentUri = new Uri.Builder()
            .scheme(ContentResolver.SCHEME_CONTENT)
            .authority(AUTHORITY)
            .appendPath(CONTENT_URI_PATH)
            .build();
    }
}

Configuring a Class

See ORMLite documents : Configuring a Class
You can use the annotations added by OrmLiteContentProvider library.

@Contract
@DefaultContentUri
@DefaultContentMimeTypeVnd
@DefaultSortOrder
@ProjectionMap

For added annotations, see the javadoc.

@DatabaseTable(tableName = Contract.Account.TABLE_NAME)
@DefaultContentUri(authority=Contract.AUTHORITY, path=Contract.Account.CONTENT_URI_PATH)
@DefaultContentMimeTypeVnd(name=Contract.Account.MIMETYPE_NAME, type=Contract.Account.MIMETYPE_TYPE)
public class Account
{
    @DatabaseField(columnName = Contract.Account._ID, generatedId = true)
    @DefaultSortOrder
    private int id;

    @DatabaseField
    private String name;

    public Account()
    {
        // ORMLite needs a no-arg constructor
    }

    public Account(String name)
    {
        this.id = 0;
        this.name = name;
    }

    public int getId()
    {
        return id;
    }

    public String getName()
    {
        return name;
    }
}

Configuring a Class with Automatic generation of Contract Class.

There is no need for special difficult. You add the @Contract annotation. And Shall be given here information underlying to produce.

@Contract()
@DatabaseTable(tableName = "accounts")
@DefaultContentUri(authority = "com.tojc.ormlite.android.ormlitecontentprovider.compiler.sample", path = "accounts")
@DefaultContentMimeTypeVnd(name = "com.tojc.ormlite.android.ormlitecontentprovider.compiler.sample.provider", type = "accounts")
public class Account
{
    @DatabaseField(columnName = BaseColumns._ID, generatedId = true)
    @DefaultSortOrder
    private int id;

    @DatabaseField
    private String name;

    public Account()
    {
        // ORMLite needs a no-arg constructor
    }

    (Omission)
}

Compiler generates the following from this definition. You do not have to write this.

public final class AccountContract implements BaseColumns
{
    public static final String TABLE_NAME = "accounts";

    public static final String AUTHORITY = "com.tojc.ormlite.android.ormlitecontentprovider.compiler.sample";

    public static final String CONTENT_URI_PATH = "accounts";

    public static final String MIMETYPE_TYPE = "accounts";
    public static final String MIMETYPE_NAME = "com.tojc.ormlite.android.ormlitecontentprovider.compiler.sample.provider";

    public static final int CONTENT_URI_PATTERN_MANY = 1;
    public static final int CONTENT_URI_PATTERN_ONE = 2;

    public static final Uri CONTENT_URI = new Uri.Builder()
        .scheme(ContentResolver.SCHEME_CONTENT)
        .authority(AUTHORITY)
        .appendPath(CONTENT_URI_PATH)
        .build();

    private AccountContract()
    {
    }

    public static final String NAME = "name";
}

Implementing the OrmLiteSqliteOpenHelper Class

See ORMLite : OrmLiteSqliteOpenHelper and Android Developers : SQLiteOpenHelper.
Implementing the OrmLiteSqliteOpenHelper class is required. How to implement OrmLiteSqliteOpenHelper, please refer to manual of ORMLite.

public class SampleHelper extends OrmLiteSqliteOpenHelper
{
    public SampleHelper(Context context)
    {
        super(context,
            Contract.DATABASE_NAME,
            null,
            Contract.DATABASE_VERSION
            );
    }

    @Override
    public void onCreate(SQLiteDatabase database, ConnectionSource connectionSource)
    {
        try
        {
            TableUtils.createTableIfNotExists(connectionSource, Account.class);
        }
        catch(SQLException e)
        {
            e.printStackTrace();
        }
    }

    @Override
    public void onUpgrade(SQLiteDatabase database, ConnectionSource connectionSource, int oldVersion, int newVersion)
    {
        try
        {
            TableUtils.dropTable(connectionSource, Account.class, true);
            TableUtils.createTable(connectionSource, Account.class);
        }
        catch(SQLException e)
        {
            e.printStackTrace();
        }
    }
}

Implementing the ContentProvider Class

See Android Developers : Implementing the ContentProvider Class
Implement an abstract class OrmLiteSimpleContentProvider.

public class MyProvider extends OrmLiteSimpleContentProvider<OrmLiteSqliteSampleHelper>
{
    @Override
    protected Class<OrmLiteSqliteSampleHelper> getHelperClass()
    {
        return OrmLiteSqliteSampleHelper.class;
    }

    @Override
    public boolean onCreate()
    {
        setMatcherController(new MatcherController()
            .add(Account.class, SubType.DIRECTORY, "", Contract.Account.CONTENT_URI_PATTERN_MANY)
            .add(Account.class, SubType.ITEM, "#", Contract.Account.CONTENT_URI_PATTERN_ONE)
            );
        return true;
    }
}

By getHelperClass() method to register the Helper class. To register for a pattern in onCreate(). Creates an instance of MatcherController To do so, call add() method.

Flexibility

This is more flexible precisely because the user can set MatcherController arbitrarily. This is the most important key points of the Android-OrmLiteContentProvider library.

// Undefined @DefaultContentUri and @DefaultContentMimeTypeVnd annotations.
// This can be defined using MatcherController.
@DatabaseTable(tableName = Contract.NewTable.TABLE_NAME)
public class NewTable
{
    @DatabaseField(columnName = Contract.NewTable._ID, generatedId = true)
    private int key;

    @DatabaseField
    private String name;

    public NewTable()
    {
        // ORMLite needs a no-arg constructor
    }

    // etc..
}

public class MyProvider extends OrmLiteSimpleContentProvider<OrmLiteSqliteSampleHelper>
{
    @Override
    protected Class<OrmLiteSqliteSampleHelper> getHelperClass()
    {
        return OrmLiteSqliteSampleHelper.class;
    }

    @Override
    public boolean onCreate()
    {
        setMatcherController(new MatcherController()
            .add(Account.class, SubType.DIRECTORY, "", Contract.Account.CONTENT_URI_PATTERN_MANY)
            .add(Account.class, SubType.ITEM, "#", Contract.Account.CONTENT_URI_PATTERN_ONE)
            
            .add(Account.class)
                .add(SubType.DIRECTORY, "", Contract.Account.CONTENT_URI_PATTERN_MANY)
                .add(SubType.ITEM, "#", Contract.Account.CONTENT_URI_PATTERN_ONE)
            // Add new table. You can add more than one table.
            // Is considered to be set to the table(class) that you have added to end.
            .add(NewTable.class)
                // Defined DefaultContentUri and DefaultContentMimeTypeVnd.
                .setDefaultContentUri(
                        Contract.AUTHORITY,
                        Contract.NewTable.CONTENT_URI_PATH)
                .setDefaultContentMimeTypeVnd(
                        Contract.NewTable.MIMETYPE_NAME,
                        Contract.NewTable.MIMETYPE_TYPE)
                // (NewTable.class)
                .add(SubType.DIRECTORY, "", Contract.NewTable.CONTENT_URI_PATTERN_MANY)
                .add(SubType.ITEM, "#", Contract.NewTable.CONTENT_URI_PATTERN_ONE)
                // add other pattern. 'content://com.example.app.provider/newtable/dataset'
                .add(SubType.DIRECTORY, "dataset", Contract.NewTable.CONTENT_URI_PATTERN_DATASET)
            );
        return true;
    }
}

The <provider> Element

See Android Developers : The <provider> Element.

Add AndroidManifest.xml

<provider android:name=".provider.MyProvider"
    android:authorities="com.tojc.ormlite.android.ormlitecontentprovidersample"
    android:exported="false"/>

Accessing a provider

See Android Developers : Content Provider Basics.
Run the test program.

public class MainActivity extends Activity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ContentValues values = new ContentValues();
        values.clear();
        values.put(Contract.Account.NAME, "Yamada Tarou");
        getContentResolver().insert(Contract.Account.contentUri, values);

        Cursor c = getContentResolver().query(Contract.Account.contentUri, null, null, null, null);
        while(c.moveToNext())
        {
            for (int i = 0; i < c.getColumnCount(); i++)
            {
                Log.d(getClass().getSimpleName(), c.getColumnName(i) + " : " + c.getString(i));
            }
        }
        c.close();
    }
}

Install

About the OrmLiteSimpleContentProvider easiest, I will introduce the procedure.

Apache Maven setup

If you use maven to build your Android project you can simply add a dependency for this library.

<dependency>
    <groupId>com.tojc.ormlite.android</groupId>
    <artifactId>ormlite-content-provider-library</artifactId>
    <version>${version}</version>
    <type>jar</type> <!-- or apklib -->
</dependency>

If you specify the 'apklib', you will need to imported the ormlite-content-provider-library to local workspace.

If you perform the automatic generation of Contract Class, Additional compiler is required.

<dependency>
    <groupId>com.tojc.ormlite.android</groupId>
    <artifactId>ormlite-content-provider-compiler</artifactId>
    <version>${version}</version>
    <scope>provided</scope>
</dependency>

Gradle setup

As with Maven, you can add the library easily with Gradle.

repositories{
    mavenCentral()
}

dependencies {
    compile "com.tojc.ormlite.android:ormlite-content-provider-library:${version}@aar" // @aar or @jar
}

If you perform the automatic generation of Contract Class, Additional compiler is required.

dependencies {
    compile "com.tojc.ormlite.android:ormlite-content-provider-compiler:${version}" // jar only
}

Other than this, you need a plugin to handle the APT. Please refer to the following.

android-apt
gradle-android-apt-plugin
gradle-apt-plugin

Manual setup

If you’re using the Eclipse with the ADT plugin, you can include a library project and compiler project.

Downloading Android-OrmLiteContentProvider

git clone git@github.com:jakenjarvis/Android-OrmLiteContentProvider.git <Anywhere>

Import Project's

Add these to your project.

ormlite-content-provider-library

Add the Android Library Project to your project.
See Android Developers : Referencing a library project

Downloading and add dependency

See stackoverflow : How to import a jar in Eclipse?

Download from ORMLite : OrmLite Releases

Copy the following files to libs folder.

ormlite-core-X.XX.jar
ormlite-android-X.XX.jar
ormlite-jdbc-X.XX.jar(If you need)

ormlite-content-provider-compiler(Optional)

Add the Java Project(Not Android Project) to your project.
Compiler will work when build your project. You do not need to include the compiler on your package.
NOTE: Manual setting be a very tedious task. You must solve all the dependencies. The following shows only important point.

Downloading and add dependency

Download from github : javawriter

javawriter-X.X.X.jar

Settings .factorypath to your project

ormlite-content-provider-compiler-sample is going to be your reference.

See Eclipse help JDT Annotation Processing : Getting Started

<factorypath>
    <factorypathentry kind="VARJAR" id="YOUR_LOCATION/ormlite-content-provider-compiler-X.X.X.jar" enabled="true" runInBatchMode="false"/>
    <factorypathentry kind="VARJAR" id="YOUR_LOCATION/ormlite-core-X.XX.jar" enabled="true" runInBatchMode="false"/>
    <factorypathentry kind="VARJAR" id="YOUR_LOCATION/ormlite-android-X.XX.jar" enabled="true" runInBatchMode="false"/>
    <factorypathentry kind="VARJAR" id="YOUR_LOCATION/javawriter-X.X.X.jar" enabled="true" runInBatchMode="false"/>
    <factorypathentry kind="VARJAR" id="YOUR_LOCATION/ormlite-content-provider-library-X.X.X.jar" enabled="true" runInBatchMode="false"/>
</factorypath>

Another solution : m2e-apt
This is a better solution to get annotation processing within eclipse using maven settings.

See m2e-apt
