我有使用AAR文件在主android项目中使用的库项目.我现在得到了我所期望的着名的65k方法限制,但我几乎没有查询.

我在我的主项目的libs文件夹中添加了AAR文件,并在build.gradle中编译了相同的文件.

1)我是否需要在库以及主要的android项目中添加multi-dex支持？

2)我是否需要在两个项目中添加afterEvaluate脚本？

最重要的是,如果我们得到多dex工作,我们可能会遇到问题,在主要的android项目中,如果我们尝试使用的任何类不在主dex列表中,我们会得到Classnotfound异常.

编辑： – 我正在尝试根据我的测试发布更新,所以任何有任何想法的人都可以帮助我们所有人.

项目中使用的依赖项： –

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.1'
    compile 'com.google.android.gms:play-services-gcm:7.8.0'
    compile 'com.google.android.gms:play-services-location:7.8.0'

    // Crashlytics Kit
    compile('com.crashlytics.sdk.android:crashlytics:2.5.1@aar') {
        transitive = true
    }
}

17-08-2015 – 根据文档,我修改了我的代码及其现在的工作,但我无法使用proguard生成签名的apk.

Proguard文件看起来像： –

-keep class ch.qos.** { *; }
-keep class org.slf4j.** { *; }
-keep class io.protostuff.** { *; }
-keep class com.google.common.** { *; }
-keep com.amazonaws.http.** { *; }
-keep com.amazonaws.internal.** { *; }
-keepattributes *Annotation*

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

# Keep SafeParcelable value, needed for reflection. This is required to support backwards
# compatibility of some classes.
-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
    public static final *** NULL;
}

# Keep the names of classes/members we need for client functionality.
-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}

# Needed for Parcelable/SafeParcelable Creators to not get stripped
-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}

我之前也遇到过这个问题,我无法在上一个项目中解决它,但这次我需要解决它.

有任何想法吗？

解决方法:

首先,查看official documentation – 它解释了如何非常详细地添加multi-dex支持.

回答：

Do I need to add multi-dex support in both library as well as main
android project?

仅在主Android项目中指定’multiDexEnabled = true'(在defaultConfig下).无需在库中声明它.

Do I need to add afterEvaluate script in both project?

适用于Android的Gradle插件v0.14.0增加了对multi-dex的支持,您不再需要添加您提到的代码.该插件将自动创建主dex列表,并将所需信息传递给dex进程.

发布结果,如果您仍然有ClassNotFoundException错误,请告诉我们.

I’m receiving the following error when trying to build a release
variant with proguard:
Warning: com.amazonaws.AmazonWebServiceClient:

在其github repo中,AWS作者在instructions中介绍了如何设置proguard配置：

-keep class org.apache.commons.logging.**               { *; }
-keep class com.amazonaws.services.sqs.QueueUrlHandler  { *; }
-keep class com.amazonaws.javax.xml.transform.sax.*     { public *; }
-keep class com.amazonaws.javax.xml.stream.**           { *; }
-keep class com.amazonaws.services.**.model.*Exception* { *; }
-keep class com.amazonaws.internal.**                   { *; }
-keep class org.codehaus.**                             { *; }
-keep class org.joda.convert.*                          { *; }
-keepattributes Signature,*Annotation*,EnclosingMethod
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class com.amazonaws.** { *; }

-dontwarn com.amazonaws.auth.policy.conditions.S3ConditionFactory
-dontwarn org.joda.time.**
-dontwarn com.fasterxml.jackson.databind.**
-dontwarn javax.xml.stream.events.**
-dontwarn org.codehaus.jackson.**

-dontwarn org.apache.http.conn.scheme.**
-dontwarn org.apache.http.annotation.**
-dontwarn org.ietf.jgss.**
-dontwarn org.w3c.dom.bootstrap.**

请注意,您的proguard配置缺少org.apache.commons.logging.**条目.
