回调执行：

1. 进入 entry: onStart---->onResume---->onAttachedToWindow------->onWindowVisibilityChanged--visibility=0---------->onWindowFocusChanged(true)------->

2. 退出应用 exit: onPause---->onStop---->onWindowFocusChanged(false) ---------------------- (lockscreen)

3. 返回上一个界面 exit : onPause----->onWindowFocusChanged(false)-------->onWindowVisibilityChanged--visibility=8------------>onStop(to another activity)

监听onActivityResult：

page

Page page = ScriptUtils.createImagPage(jsContext, this);
page.setUrl(url);
page.setXml(xml);
page.parse(url, xml);

获取activity,jsContext
public Imag(org.mozilla.javascript.Context jsContext, Activity activity) {
        this.jsContext = jsContext;
        this.activity = activity;
        this.context = activity;

this.imag = (Imag) ScriptableObject.getTopLevelScope(this);
this.jsContext = imag.getJsContext();
this.activity = imag.getActivity();
