無法從Android應用程序啓動音頻鏈接

我試圖從我的應用程序啓動將從流式服務器播放音頻的意圖。我已經得到了該流的url和我使用bit.ly來簡化URL以啓動（我試過沒有bit.ly並具有相同的結果）無法從Android應用程序啓動音頻鏈接

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);

瀏覽器啓動時，加載了bit.ly鏈接，重定向到音頻鏈接，然後關閉並返回到我的應用程序

當我啓動手動瀏覽器相同的bit.ly鏈接，它工作正常（啓動音頻流應用程序）：

我試過擺弄各種intent.setFlags參數，但無濟於事。也許權限問題？或者我如何調用startActivity？

沒有權限問題，它只是BrowserActivity過早結束，也許是因爲沒有當前選項卡。做的最好的事情就是給一個額外的線索意圖解析器，它實際上不是應該處理數據的瀏覽器：

intent.setType("audio/mpeg");

不需要進行其他的標誌...聲音播放器（或媒體播放器選擇）現在將處理它。

啊，謝謝你的提示。這並沒有做到，但它指出了我的正確方向......我需要調用intent = new Intent（Intent.ACTION_VIEW）; intent.addCategory（Intent.CATEGORY_DEFAULT）; intent.setDataAndType（uriObj，mimeType）; 似乎需要調用「setDataAndType」。很奇怪。 – Eric 2010-12-23 19:37:49
