方法ID不在[0,0xffff]: 65536小应用错误

Question

我们确实有一个小应用程序，不过，使用大约10jar。我被它缠住了。我配置了Proguard，它仍然显示同样的内容。根据Proguard的结果，我们只有500多个未使用的方法。我能做错什么或错过什么?

下面是gradle文件的依赖项:

Our "library"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')
}

app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')
}

下面是我的proguard代码:

Answer 1

ProGuard可能会为您删除许多类和方法，但是您的配置相当保守，显式地保留了许多类、字段和方法:

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

你可能在一个单独的文件中有更多的选项，例如Facebook SDK?

注意，文件proguard-project.txt基本上可以是空的，因为大部分配置已经在共享配置文件${sdk.dir}/tools/proguard/proguard-android.txt中指定(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。

你也不应该在配置文件中指定-injars或-libraryjars选项。Gradle构建过程已经自动为您指定了所有必需的-injars、-outjars和-libraryjars。

Answer 2

所以，我能够修复它。proguard代码实际上很好，但我把它放在错误的文件中。它应该在生成索引文件的模块中。我以前把它放在静态库中。

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

谢谢。:)
