アプリケーションを完成させたばかりなので、ProGuard で難読化したいと考えました。アプリケーションはholoeverywhereAction Bar Sherlock のライブラリを使用しているので、ProGuard に伝えてみました。私は Eclipse を使用しています。これは project.properties ファイルです。
# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system edit
# "ant.properties", and override values to adapt the script to your
# project structure.
#
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
# Project target.
target=android-19
android.library.reference.1=..\\HoloEverywhere Addon Preferences
何も追加も削除もしていません。
これは私のproguard-project.txtです：
# 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 *;
#}
-keep class com.actionbarsherlock.**
-keep class org.holoeverywhere.**

それが役立つ場合、これは私の依存関係の画面です:
アプリケーションをエクスポートするときにエラーや警告は表示されませんが、Android フォンにインストールすると、アプリケーションを開くとクラッシュします。これは、スタック トレースです。
