無法獲得寫設置權限當我在AndroidMPreview 3上的目標API為23時，我似乎無法獲得Manifest.Licsion.WRITE_SET權限。 requestPermissions(new String[]{Manifest.permission.WRITE_SETTINGS},
101);請求權限不會彈出我期望的對話框，但是如果我在沒有此權限的情況下進行以下調用， RingtoneManager.setActualDefaultRingtoneUri(activity, RingtoneManager.TYPE_RINGTONE, ringUri);除非我沒有得到許可，否則我會打電話的。我不知道從這里往哪里走。有23的新鈴聲API嗎？還是這一權限的改變僅僅使任何非系統應用程序都無法改變鈴聲？
