Android的音頻流站（進入暫停）

我有一個銀河S5採用Android 6.0.1版本節電模式爲「關」和超省電模式爲「關」Android的音頻流站（進入暫停）

我已經試過三大互聯網音樂流媒體應用程序即：潘多拉，SiriusXM和WDET Radio。

在每種情況下，音樂/音頻素材會播放一段時間（大約幾分鐘），然後在「暫停」時應用會關閉應用程序（播放按鈕出現，音頻將在按下播放按鈕時繼續播放）。這可能隨時發生，換句話說，它不會發生在音軌的末尾。

我已經在這個主題上搜索過，唯一能找到的建議是確保省電模式設置爲關閉。我沒有這些應用程序的源代碼，所以我只能記錄應用程序啓用的內容。

我在「aud」上過濾時捕獲了一些logcat痕跡。我嘗試了各種過濾器（也沒有過濾），但是我在「aud」過濾之前看不到模式。

我粘貼了一段logcat，顯示潘多拉的啓動時間從21:33:53到21:39，當我關閉應用時。條目：

12-29 21:38:03.712 767-1806/? W/MediaFocusControl: AudioFocus audio focus client died

指示何時檢測到靜音音頻（通過收聽）。沒有用戶干預導致這種情況。該logcat的條目如下：

音頻重點客戶的第二個實例死亡發生在：

12-29 21:39:41.392 767-786/? W/MediaFocusControl: AudioFocus audio focus client died

發生這種情況，我打的後退按鈕，然後從媒體通知關閉該應用程序後。

就「音頻焦點客戶端死亡」和屏蔽行爲而言，SiriusXM和WDET Radio應用程序都給出了類似的行爲。我是這些應用程序的最終用戶，但由於他們都以類似的方式行事，我認爲它必須與我的設備配置有關。無論是否有Wifi或LTE作爲我的數據鏈接，都會發生這種情況。此外，同樣的最終行爲發生（當它進入「暫停」時，音頻丟失），無論是通過USB還是USB連接啓用日誌記錄。

我在過去並沒有注意到這種行爲，但我不能說它在什麼時候開始發生。

什麼會導致音頻像這樣單方面靜音？

在我的Android上有一些設置會導致這種情況嗎？

是否有更多信息可以幫助解決此問題？

非常感謝。吉姆

新信息： 我跑了一些測試，發現如下logcat的模式（四分之四個的測試結果）時，音頻重點客戶被宣佈死亡：

測試1：

Test3的：

TEST4：

12-30 17:10:18.731 809-1502/? W/MediaFocusControl: AudioFocus audio focus client died

在每種情況下的音頻停在本質上是相同的時間ActivityManager被殺害連接BMW應用程序。

這是否意味着BMW Connected應用程序具有音頻焦點，即使它沒有流出音頻？

其他應用程序（SiriusXM，潘多拉或WDET無線電）是流音頻。

我卸載了Connected BMW應用程序，並且三個應用程序（SiriusXM，Pandora和WDET Radio）每個都連續播放了20分鐘。無論如何，我從未使用連接的應用程序。

這可能是因爲Android操作系統將會終止的服務，由於缺乏資源。你可以使你的服務前景避免它。這裏是snippit：

private void sendToForeground() { 
    Notification note = new Notification(0, null, 
     System.currentTimeMillis()); 
    note.flags |= Notification.FLAG_NO_CLEAR; 
    startForeground(0, note); 
}

只是在onCreate服務。

正如我在我的文章中指出的，這些應用程序已下載到我的Android手機中。我是這些應用程序的最終用戶。我只是想弄清楚爲什麼3個應用程序似乎以相同的方式失敗，並且如果有什麼我可以在設備上配置，以防止這種行爲。 – JimCzek
