Squeaky for Android 
SQLite is simple and lightweight; it follows that managing SQLite databases on Android should be also.
Squeaky strives to be a straightforward approach to creating, migrating, and accessing SQLite databases.
Setup
Add jitpack.io to your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}Add Squeaky-Android as a dependency to your app's build.gradle:
dependencies {
compile 'com.github.jasonwyatt:squeaky-android:1.2.0'
}Getting Started
Define your Tables
import co.jasonwyatt.squeaky.Table
public class TodosTable extends Table {
@Override
public String getName() {
return "todos";
}
@Override
public int getVersion() {
return 1;
}
@Override
public String[] getCreateTable() {
return new String[] {
"CREATE TABLE todos ("+
" name TEXT NOT NULL"+
" completed INTEGER NOT NULL DEFAULT 0"+
")"
};
}
@Override
public String[] getMigration(int nextVersion) {
return new String[0];
}
}
Create your Database and add Tables to it
// in your Application's or Activity's onCreate() method
Database myDB = new Database(this, "todos_db");
myDb.addTable(new TodosTable());
myDb.prepare();
Use it!
myDb.insert("INSERT INTO todos (name) VALUES (?)", "Learn how to use Squeaky");
myDb.insert("INSERT INTO todos (name, completed) VALUES (?, ?)", "Already done", 1);
// query
Cursor c = myDb.query("SELECT rowid, name, completed FROM todos");
while (c.moveToNext()) {
// get values
long rowid = c.getLong(0);
String name = c.getString(1);
boolean completed = c.getInt(2) == 1;
}
// in an OnClickListener, for example..
myDb.update("UPDATE todos SET completed = 1 WHERE rowid = ?", rowid);
Migrate a Table
Modify your Table definition class:
import co.jasonwyatt.squeaky.Table
public class TodosTable extends Table {
@Override
public String getName() {
return "todos";
}
@Override
public int getVersion() {
return 2;
}
@Override
public String[] getCreateTable() {
return new String[] {
"CREATE TABLE todos ("+
" name TEXT NOT NULL"+
" completed INTEGER NOT NULL DEFAULT 0"+
" due_date INTEGER"+
")"
};
}
@Override
public String[] getMigration(int nextVersion) {
if (nextVersion == 2) {
return new String[] {
"ALTER TABLE todos ADD COLUMN due_date INTEGER"
};
}
return new String[0];
}
}
That's it. Next time your database is prepared after adding the table definition, the table will be migrated for you!
