容器迭代二

## 后台播放音频功能
### js接口调用方式
```js
ZhuanQuanJSBridge.call('media', data: JSON, function(res) {
  // 回调
});
```
### 其中data的格式有几种情况
#### 传递信息给后台播放器
```js
{
  key: "info",
  value: {
    url: "音频地址",
    id: "音频id",
  },
}
```
逻辑细节：
* 尝试使用边播边缓存，即播放过的内容缓存下来，下次再播可以节省网络请求。播放过的内容可能为整首音乐，也可能是一首音乐的一部分（如前10秒）。android中结合使用了`EXOPlayer`+`OKHttp`，http网络请求及缓存功能由`OKHttp`实现。
* 每次调用时判断id和上一次是否相同，如是则说明同一首，直接略过后续逻辑；如否将url传递给后台播放器，同时停止之前可能正在播放的音乐。
#### 播放
```js
{
  key: "play",
}
```
```js
{
  key: "play",
  value: {
    url: "音频地址",
    id: "音频id",
  },
}
```
逻辑细节：
* 没有value时，开始播放当前音乐（之前通过info传递）。
* 有value时，复用info逻辑将value作为参数传递给info，再开始播放。
* 调用结束后，进行回调，将id作为参数传回：https://github.com/uyutech/android/blob/fragment/app/src/main/java/cc/circling/MediaService.java#L249-L251
#### 暂停
```js
{
  key: "pause",
}
```
逻辑细节：
* 暂停当前播放的音乐，保持住当前的信息（如播放时间位置）。
* 调用结束后，进行回调，将id作为参数传回，同上。
#### 停止
```js
{
  key: "stop",
}
```
逻辑细节：
* 停止当前播放的音乐，播放进度清零但保持住当前的信息（如播放url和id）。
* 调用结束后，进行回调，将id作为参数传回，同上。
#### 停止并释放资源
```js
{
  key: "release",
}
```
逻辑细节：
* 停止当前播放的音乐，释放资源和清空信息（如url和id和记录的上次播放id）。
* 调用结束后，进行回调，将id作为参数传回，同上。
#### 跳转到特定时间位置进行播放
```js
{
  key: "seek",
  value: {
    time: int, // 秒数
  },
}
```
逻辑细节：
* 播放进度跳到多少秒
* 调用结束后，进行回调，将id作为参数传回，同上。
#### 其它
当传递的`data`或者`key`为空或者`key`为其它值时，忽略，此举为兼容老版android特定逻辑使用。
### 播放加载时的事件
这些事件均发送给当前的view（最上层可见活动view）的webview。
#### mediaPrepared
传递info后，播放器加载资源得到媒体信息（duration时长毫秒）后发出，附上id和duration信息：https://github.com/uyutech/android/blob/fragment/app/src/main/java/cc/circling/MediaService.java#L146-L150
#### mediaProgress
传递info后，播放器加载资源的进度，附上id、percent（已加载百分比）、duration、position（已加载时长毫秒）：https://github.com/uyutech/android/blob/fragment/app/src/main/java/cc/circling/MediaService.java#L130-L137
#### mediaEnd
当播放到末尾时调用，附上id信息：https://github.com/uyutech/android/blob/fragment/app/src/main/java/cc/circling/MediaService.java#L156-L158
特别注意音乐停止后可能会再调用一次`play`方法，此时要求音乐从头重新播放。android做法为停止时将播放器seek时间变为0。
#### mediaTimeupdate
在播放音乐时，发送当前播放时间，附上id、currentTime（当前播放时间毫秒）、duration、percent：https://github.com/uyutech/android/blob/fragment/app/src/main/java/cc/circling/MediaService.java#L197-L203
## 其它小优化调整
### 针对webview在进出前后台时的操作
如果可行，当每个页面的view进入后台时（按下Home键，或者有新的view进行pushwindow盖在当前view上面），其所包含的webview暂停运行js（android为调用webview.onPause()方法）；反之恢复到前台时，恢复js运行（android为调用webview.onResume()方法）。
### webview中视频全屏自动横屏
android自动，ios为竖屏。https://www.jianshu.com/p/f1a0b96fb03a
