Schematic

Automatically generate a ContentProvider backed by an SQLite database.

Usage

First create a class that contains the columns of a database table.

public interface ListColumns {

  @DataType(INTEGER) @PrimaryKey @AutoIncrement String _ID = "_id";

  @DataType(TEXT) @NotNull String TITLE = "title";
}

Then create a database that uses this column

@Database(version = NotesDatabase.VERSION)
public final class NotesDatabase {

  public static final int VERSION = 1;

  @Table(ListColumns.class) public static final String LISTS = "lists";
}

And finally define a ContentProvider

@ContentProvider(authority = NotesProvider.AUTHORITY, database = NotesDatabase.class)
public final class NotesProvider {

  public static final String AUTHORITY = "net.simonvt.schematic.sample.NotesProvider";

  @TableEndpoint(table = NotesDatabase.LISTS) public static class Lists {

    @ContentUri(
        path = Path.LISTS,
        type = "vnd.android.cursor.dir/list",
        defaultSort = ListColumns.TITLE + " ASC")
    public static final Uri LISTS = Uri.parse("content://" + AUTHORITY + "/lists")
  }

Including in your project

I recommend using the android-apt plugin. It doesn't include the compiler artifact in the final apk, and also sets the source paths so AS picks it up the generated classes.

apply plugin: 'com.android.application'
apply plugin: 'android-apt'

buildscript {
  repositories {
    mavenCentral()
  }

  dependencies {
    classpath 'com.android.tools.build:gradle:{latest-version}'
    classpath 'com.neenbedankt.gradle.plugins:{latest-version}'
  }
}

dependencies {
  apt 'net.simonvt.schematic:schematic-compiler:{latest-version}'
  compile 'net.simonvt.schematic:schematic:{latest-version}'
}
