NullPointerException异常的三星Galaxy S调用铃声preference时

问题描述

我的三星Galaxy（一切正常，其他电话）呼叫铃声preference时，得到下面的消息

I am getting the following message when calling RingTonePreference on Samsung Galaxy (everything works fine on other phones):

java.lang.RuntimeException: Unable to start activity ComponentInfo{android/com.a

更新：这是它是如何被称为：

UPDATE: Here is how it is called :

 <RingtonePreference android:key="pref_notification_ringTone"
                android:title="@string/pref_notification_Ringtone"
                android:ringtoneType="notification" android:showDefault="true"
                android:showSilent="false" />

PS：我知道了类似的问题已经被问过，但没有答案被赋予（Notification或报警声选择器崩溃上的Galaxy S ?? ）

推荐答案

此问题是由在定义设置showSilent =真解决，显然是专门针对Galaxy S的一个bug。

This issue was resolved by setting "showSilent=true" in the definition and is apparently a bug specific to the Galaxy S.
