Todo: 3、添加“主动缓存”，下载后歌名附加图标(isCached=true存入本地数据库)（主动缓存前即使被动缓存完毕也不自动触发，但可以依赖于被动缓存，测试“未播放，不触发被动，仅主动缓存”后的play），主动缓存后存入与被动缓存不同本地文件夹(Next: 为其专门开设Local List)。 4、只能删除已经“主动缓存”过、isCached=true、有小图标的音乐，删除后被动缓存依然存在，可以[清空“被动缓存”]。 5、添加离线模式，在线模式：按照ALLMusic返回列表，结合SQL标注缓存过的文件。离线模式：Scan主动缓存文件夹(读取本地SQL)。

1. Run

• Platform (Recommended): "Xiaomi Redmi 5A (Android 7.1.2, API25)"
• Resolution (Recommended): W x H = 720 x 1280 (5-Inch)
• Network: Thie App needs Internet to access its server. For example, to "login", access file system.
• Browser: This App needs to start implicit intent of HTTP-URI targeting browser application. For example, to "download", "preview" and "upload".
• Downloader: This App could start implicit intent of HTTP-URI targeting downloader application (or download management application).

2. Develop

• IDE: Android Studio
• SDK Version: compileSdkVersion 28; targetSdkVersion 28; minSdkVersion 21;
• Extra Dependency: 'com.google.code.gson:gson:2.8.2', 'com.danikula:videocache:2.7.1'

3. Message Handler

• 0x11 - onLogin
• 0x21 - onRegister
• 0x12 - onFileGet for MainActivity/FileFragment/
• 0x13 - onAllMP3Get for MP3Fragment
• 0x16 - onDeleteFile for FileInfoListAdaptor
• 0x17 - onRenameFile for FileInfoListAdaptor
• 0x18 - onCreatedFolder for FileFragment
• 0x22 - onChangePassword

Music Passive Cache

• Basic: When listen to music, download it from the "playing stream" with no extra network cost.
• Clear Cache: Can Clear Music Passive Cache.
• Over-drag: When over-drag, wait for downloading all data in the middle, and continue.
• Network-cut: Available until timestamp when net is cut, when restart, former cached part also available.
• Offline Jump To Un-cached Song: Stop play without hint.

Implementation Logic Note

• MainActivity -> TabLayout -> ViewPager -> PagerAdaptor -> Fragment (-> ArrayAdaptor)
• MusicPlayerActivity (REAL BODY: Top Bar, Body, Progress Bar), Following Backdrop Design's "HIDDEN BODY".
• MusicPlayerActivity (HIDDEN BODY: Peek Height (Control Bar, Footer), Bottom Top Bar, Bottom Body)
• MusicService (HttpCacheProxy + ResourceList), Body, when change music, to find visible list item to make it highlight, in adaptor, also give a highlight logic.
