我想在android中开发一个视频通话程序.我想过使用android 2.3.3中引入的内置sip.但是,我该如何发起视频通话?我看到它不受支持.
我正在尝试集成 In App Review,但收到此编译错误:

现在,我的应用程序中有一个我不支持的链接.所以我在同时做的是用外部浏览器打开它.像这样:
String requestURL = "www.example.com/unsupportedlink";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(requestURL));
mActivity.startActivity(i);

我期望它会在浏览器上打开,但是如果用户选择默认情况下应用程序打开所有链接("Allways open"而不是"Just Once"),则再次调用app并发送链接再次访问浏览器 - 它会导致无限循环.我怎么能避免这个?
我有这个jQuery函数可以工作.除了微小的变化外,每两行是相同的.我怎样才能缩短它?

点代表代码.显然这不是方法,因为平台引发了异常.
有人可以帮忙吗?
我试图运行它但它崩溃时它到达getDefaultSharedPreferences().为什么?
这是首选项活动.IntentService当它被摧毁时它会发射
