Android - twitter4j Proguard 错误

Question

我在尝试混淆我的 apk 时遇到问题 - 与 this SO question 中报告的问题相同。我为该问题应用了公认的答案，然后构建了我的 apk。

但是，当我运行我的应用程序时，它在显示第一个初始屏幕之前就崩溃了。

我该如何调试这个和/或我的 proguard-project.txt 文件中是否缺少任何内容？？...

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

-dontwarn twitter4j.**

注意 - 我还在我的应用中使用 android-support-v4.jar 和 acra-4.5.0.jar 库。

Answer 1

将-keep class twitter4j.** { *; } 添加到您的proguard-project.txt 文件中。

Answer 2

看起来有很多问题。最后整理好了。如果它对其他人有帮助，这里是我完整的 proguard-project.txt 文件：

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
