Question

我正在尝试从我的应用程序启动一个将从流媒体服务器播放音频的意图。我有一个该流的网址，我正在使用bit.ly来简化发布的网址（我尝试过没有bit.ly并且有相同的结果）

intent = new Intent( Intent.ACTION_VIEW, Uri.parse( "http://bit.ly/gKltQE" ) );
intent.setFlags( Intent.FLAG_ACTIVITY_NEW_TASK ); // i tried with and without this, no luck
startActivity( intent );

浏览器启动，加载bit.ly链接，重定向到音频链接然后关闭并返回到我的应用程序

当我手动在浏览器中启动相同的bit.ly链接时，它工作正常（启动音频流应用程序）：

我试过摆弄各种intent.setFlags参数，但无济于事。可能是权限问题？或者与我如何调用startActivity有关？

Answer 1

不是权限问题，只是BrowserActivity过早结束，可能是因为没有当前标签。最好的办法是给Intent解析器一个额外的线索，它实际上不是应该处理数据的浏览器：

intent.setType("audio/mpeg");

不需要其他标志......声音播放器（或您选择的媒体播放器）现在将处理它。
