Question

我正在获取自定义DialogPreference类的ClassNotFoundExption，但只能在发布版本之后。我非常适合调试版本。

这是堆栈跟踪：

在堆栈跟踪中调用的xml文件是：

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" android:key="screen">
  <PreferenceCategory android:title="@string/pref.title" android:key="cat1" android:order="1">
    <path.to.my.app.preferences.SeekBarPreference android:title="@string/perimeter.head" android:key="myapp.perimeter" android:defaultValue="30" android:text=" km" android:max="80" min="5" android:progress="0"/>
    <CheckBoxPreference android:key="myapp.saveFav" android:enabled="true" android:title="@string/fav.save.title" android:summary="@string/fav.save"></CheckBoxPreference>
  </PreferenceCategory>
    <PreferenceCategory android:title="@string/pref.personal" android:order="2">
    <EditTextPreference android:title="@string/search.customerNumber" android:key="myapp.wizard" android:inputType="textCapCharacters" android:maxLength="7"></EditTextPreference>

    <EditTextPreference android:title="@string/reservation.lastName" android:key="myapp.lastName" android:inputType="textCapWords|textPersonName"></EditTextPreference>

    <EditTextPreference android:title="@string/reservation.zip" android:key="myapp.zip" android:inputType="textCapWords|textPostalAddress"></EditTextPreference>
    <EditTextPreference android:title="@string/reservation.city" android:key="myapp.city" android:inputType="textCapWords"></EditTextPreference>
    <EditTextPreference android:title="@string/reservation.phone" android:key="myapp.phone" android:inputType="phone"></EditTextPreference>
</PreferenceCategory>
<PreferenceCategory android:order="3">
    <EditTextPreference android:title="@string/search.awdNumber" android:key="myapp.awd" android:inputType="textCapCharacters" android:maxLength="6">                    </EditTextPreference>
    <EditTextPreference android:title="@string/costControl.label" android:key="myapp.costControl" android:inputType="textCapWords" android:maxLength="15"></EditTextPreference>
    </PreferenceCategory>
</PreferenceScreen>

对于发布版本，我正在使用ProGuard，并且已经有一行

-keep public class path.to.my.app.preferences.SeekBarPreference

在配置文件中。

对此有任何有用的提示吗？

我找到了解决方案（可能不是最好的？）。我添加了

-keep class * extends android.preference.DialogPreference { 
    public <init>(android.content.Context); 
    public <init>(android.content.Context, android.util.AttributeSet); 
    public <init>(android.content.Context, android.util.AttributeSet, int); 
    public void set*(...); 
}

到proguard.cfg。
