Facebook的Android ProGuard设置

Question

我终于找到了为什么我的应用程序崩溃为了发布而构建.ProGuard确实从我的应用程序中剥离了代码,但我通过在proguard-android.txt(在sdk中找到)中手动添加带有keep命令的类来防止这种情况.

对于Facebook,我用过:

-keep class com.facebook.android.*
-keep class android.webkit.WebViewClient
-keep class * extends android.webkit.WebViewClient
-keepclassmembers class * extends android.webkit.WebViewClient { 
    <methods>; 
}

但我想我仍然缺少一些东西.该应用程序现在无崩溃,但我无法登录Facebook并使用Open Graph.当我在调试模式下构建时,一切正常.

使用Facebook和Facebook的Open Graph有哪些设置？

编辑

这是我为ProGuard手动添加的命令:

-dontwarn android.support.**

# ActionBarSherlock 

-keep class android.support.** { *; } 

-keep interface android.support.** { *; } 

-keep class com.actionbarsherlock.** { *; } 

-keep interface com.actionbarsherlock.** { *; } 




# Keep line numbers to alleviate debugging stack traces 

-renamesourcefileattribute SourceFile 

-keepattributes SourceFile,LineNumberTable

-keepclassmembers class * implements java.io.Serializable
{
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}

-keep class com.facebook.android.*
-keep class android.webkit.WebViewClient
-keep class * extends android.webkit.WebViewClient
-keepclassmembers class * extends android.webkit.WebViewClient { 
    <methods>; 
}

编辑2 所以没有登录的问题是我使用了我的调试哈希键而不是我的发布哈希键.在我的应用程序设置(developers.facebook.com)中更改了该内容,发现我的应用程序最终登录但登录后崩溃.

不知道这是否仍然是ProGuard问题,但它返回了此错误:

Answer 1

固定:

-keep class com.facebook.** {
   *;
}

代替:

-keepattributes Signature
-keep class com.facebook.android.*
-keep class android.webkit.WebViewClient
-keep class * extends android.webkit.WebViewClient
-keepclassmembers class * extends android.webkit.WebViewClient { 
    <methods>; 
}

另外,请务必在Facebook应用设置中检查您的哈希键.

Answer 2

就我而言,你的解决方案

-keep class com.facebook.** {
   *;
}

工作,但我必须保持

-keepattributes Signature

为了让一切正常.
