LitePal是一款開源Android資料庫框架，採用了物件關係對映的模式，

詳細的使用文件見LitePal專案的Github主頁

快速設定步驟：

1. Include library

Edit your build.gradle file and add below dependency.

If you program with Java:

dependencies {
    implementation 'org.litepal.android:java:3.0.0'
}

2. Configure litepal.xml

Create a file in the assets

<?xml version="1.0" encoding="utf-8"?> <litepal> <dbname value="demo" />  <version value="1" />  <list> </list> </litepal>

This is the only configuration file, and the properties are simple.

• dbname configure the database name of project.
• version configure the version of database. Each time you want to upgrade database, plus the value here.
• list configure the mapping classes.
• storage configure where the database file should be stored. internal and external are the only valid options.

3. Configure LitePalApplication

You don't want to pass the Context param all the time. To makes the APIs simple, just configure the LitePalApplication in AndroidManifest.xml as below:

<manifest>
    <application
        android:name="org.litepal.LitePalApplication" ... > ... </application> </manifest>
