Question

我在更新Android Studio和SDK后发现了这些错误：

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class
Error:(org.apache.log4j.chainsaw.ControlPanel$1) that doesn't come with an

如果有人知道任何事情......请帮助我！我在这个“NEULAND”中找不到任何东西

很抱歉这个问题很长...感谢所有在这里做过的人。

但一切都没有改变。我仍然有大约500个构建错误....我删除了mindpipe作为参考，我自己编码...没有发生任何事情！

卸载Android Studio 2.0并再次安装1.5.1后，我收到以下警告：

警告：需要Gradle版本2.10。目前的版本是2.8。如果使用gradle包装器，请尝试将C：\ Sources \ iRecyApps \ iRecyMulco-1.0.1iOS \ gradle \ wrapper \ gradle-wrapper.properties中的distributionUrl编辑为gradle-2.10-all.zip

所以gradle版本更新了2 ...

我告诉自己当前的gradle版本，它是2.12

我下载了两个并尝试了这个：

您需要更改文件＆gt;设置＆gt;构建，执行，部署＆gt;构建工具＆gt; Gradle＆gt; Gradle home path

在Mac OS上，更改Android Studio中的路径＆gt;偏好＆gt;构建，执行，部署＆gt;构建工具＆gt; Gradle＆gt; Gradle home

或设置使用默认gradle包装并编辑Project \ gradle \ wrapper \ gradle-wrapper.properties文件字段distributionUrl，如下所示

根据：

仍然没有

Answer 1

将此行添加到proguard-rules.pro

-keepattributes EnclosingMethod

我认为，几乎所有具有InnerClasses的类都可能发生此错误。（对于support.v4等）对我来说。

我已经测试过了 Android studio 2.2
（未测试log4j。经过测试的support.v4等。）

<强>的build.gradle

compileSdkVersion 24
buildToolsVersion "24.0.2"
...
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
...
dependencies {
    ...
    compile 'com.android.support:support-v4:24.2.1'
}

getDefaultProguardFile('proguard-android-optimize.txt')也有效。

Answer 2

我也面临同样的错误。它让我发疯，因为错误计数大于1K。我在启用proguard的版本构建中遇到了这些错误。

在进行一些挖掘后，我发现在-keepattributes EnclosingMethod文件中添加proguard-rules.pro所有这些错误都将消失。

GitHub上的

来源：Thread和Issue #294。

Answer 3

通过在Gradle配置中将所有com.android.support依赖项降级为23.1.1来解决。

Answer 4

就我而言，我在启用Instant Run时遇到了此错误，但在禁用Instant Run后，错误消失了。

Answer 5

在项目的proguard-rules.pro中编写此代码段。

-keepattributes EnclosingMethod

通过将上述代码段写入proguard-rules.pro文件，proguard规则实际上会更改类的混淆方式。

Answer 6

这对我有用，启动了一个新的Android工作室项目复制并粘贴旧项目中出现错误的gradle-wrapper.properties和build.gradle（项目：“项目名称”） - 以升级您的gradle

另外在proguard-rules.pro

中添加

-keepattributes EnclosingMethod

按如下所示更新build.gradle（Module：app）

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

    }

    dexOptions {
        preDexLibraries = false
    }

使用log4j更新Android Studio后，gradle构建出错
