Question

我们确实有一个小应用程序，使用大约10个月。我坚持了下来。我配置了Proguard，它仍然说同样的事情。根据Proguard结果，我们只有500多种未使用的方法。我可能做错了什么或错过了什么？

以下是gradle文件依赖项：

我们的“图书馆”模块：

dependencies {
    compile 'com.android.support:support-v4:20.+'
    compile 'com.google.android.gms:play-services:+'
    compile files('libs/jackson-annotations-2.2.3.jar')
    compile files('libs/jackson-core-2.2.3.jar')
    compile files('libs/jackson-databind-2.2.3.jar')
    compile files('libs/okhttp-1.6.0.jar')
    compile files('libs/okhttp-urlconnection-1.6.0.jar')
    compile files('libs/okio-1.0.0.jar')
    compile files('libs/ormlite-android-4.48.jar')
    compile files('libs/ormlite-core-4.48.jar')
    compile files('libs/otto-1.3.4.jar')
    compile files('libs/picasso-2.3.2.jar')
    compile files('libs/retrofit-1.5.1.jar')
    compile project(':googlemapssdkm4b_lib')
}

应用模块：

dependencies {
    compile project(':sherpaTaxiLibrary')
    compile project(':facebookSDK')
    compile project(':v4PrefFragment')
    compile 'com.android.support:appcompat-v7:20.+'
    compile 'com.android.support:support-v4:20.+'
    compile 'com.google.android.gms:play-services:+'
    compile 'com.jakewharton:butterknife:5.1.1'
    compile 'com.braintreepayments.api:braintree:1.+'
    compile files('libs/twitter4j-core-4.0.2.jar')
}

以下是我的程序代码：

先谢谢。

Answer 1

ProGuard可能会为您删除许多类和方法，但您的配置相当保守，明确保留了许多类，字段和方法：

-keep class com.google.gson.** { *; }
-keep class com.google.inject.* { *; }
-keep class org.apache.http.* { *; }
.....

您可能在单独的文件中有更多选项，例如对于Facebook SDK？

请注意，文件proguard-project.txt在开始时基本上可以为空，因为已在共享配置文件${sdk.dir}/tools/proguard/proguard-android.txt中指定了大部分配置（从project.properties引用）。使用正确的-keep选项创建更好的配置可能需要一些研究和实验。

您也不应在配置文件中指定-injars或-libraryjars选项。 Gradle构建过程已自动为您指定所有必需的-injars，-outjars和-libraryjars。

Answer 2

所以，我能够解决它。 proguard代码实际上很好，但我将它放在错误的文件中。它应该在生成dex文件的模块中。我之前把它放在静态库中。

此外，我使用https://gist.github.com/dmarcato/d7c91b94214acd936e42删除了我不使用的Google Play服务包。我将代码放在生成APK的模块的gradle文件中。

感谢。：）
