在获得65k方法限制后,我实现了多索引。在实现多索引之后,我可以运行应用程序。但是现在我从外部jar中得到了一个类的错误noclasdeffounderror。
这是我的毕业档案--

dependencies {
    compile project(':pull-to-refresh')
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':gson-2.2.2')
    compile files('libs/android-support-multidex.jar')
    compile 'com.android.support:appcompat-v7:21.0.0'
    compile 'com.google.android.gms:play-services:6.1.71'
    compile 'com.android.support:support-v4:21.0.0'
}


android {
    compileSdkVersion 21
    buildToolsVersion '21.1.1'

    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
    dexOptions {
        preDexLibraries = false
    }
    afterEvaluate {
        tasks.matching {
            it.name.startsWith('dex')
        }.each { dx ->
            if (dx.additionalParameters == null) {
                dx.additionalParameters = ['--multi-dex']
            } else {
                dx.additionalParameters += '--multi-dex'`enter code here`
            }
        }
    }
}

最佳答案

我可以通过确保multidex.install行在调用super.attachbasecontext之后修复这个问题。如果在super.attach之前调用install,显然它没有正确注册。不过,简单地更改应用程序类以扩展多索引应用程序(而不是应用程序)可能是更好的选择。
注意:扩展multidexapplication之后,不再需要重写attachbasecontext并调用multidex.install(this)。如果您查看multidexapplication(here)的源代码,您将看到该类的全部用途是为您调用install。
google(posted here)的官方说明为您指出了multidexapplication(posted here)的文档,该页面包含了解决此问题的多个选项的说明,但我第一次错过了,因此我相信许多其他人也会这样做。
