gradle慢 - android studio gradle下载



android:将字节转换为dex时出错 (20)

因此,从以下版本升级build.gradle(Project)后,在运行项目时出现以下错误

dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
}

dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-alpha3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
}

我只是将gradle从 2.0.0-alpha2 更改为 2.0.0-alpha3 ,然后尝试构建项目。

之前:

compile 'com.google.android.gms:play-services-location:10.0.1'
compile 'com.google.android.gms:play-services-auth:10.0.1'
compile 'com.google.firebase:firebase-database:10.2.0'
compile 'com.google.firebase:firebase-core:10.2.0'
compile 'com.google.firebase:firebase-messaging:10.2.0'

后:

compile 'com.google.android.gms:play-services-location:10.2.0'
compile 'com.google.android.gms:play-services-auth:10.2.0'
compile 'com.google.firebase:firebase-database:10.2.0'
compile 'com.google.firebase:firebase-core:10.2.0'
compile 'com.google.firebase:firebase-messaging:10.2.0'

终于解决了。


升级到Android Studio 2.1之后,下次重新启动时,系统要求我升级到JDK 1.8。 在我升级到JDK 1.8之后,那就是我的AS项目无法编译的时候。 我遵循了此页面中的所有建议,但无济于事。 最后,我决定检查项目使用的JDK版本,令我惊讶的是,它某种程度上指向了JDK 1.8!

故事的寓意:如果compileSdkVersion <= 23,请仔细检查您的项目是否使用JDK1.7,如下所示:

  • 鼠标在顶层模块上
  • 项目结构=> JDK位置

只需 restart 您的AS,然后 Rebuild 您的应用程序即可!


在我的情况下,我发现此问题是由于build.gradle的配置不正确引起的。 我有com.google.firebase的两个不同版本。 一旦版本相同,问题就解决了


如果从2个不同的来源将相同的库引入代码中,则会导致错误。


如果它对某人有所帮助,就我而言,我是在发布模式下而不是在调试模式下使用自定义程序包。

我只是将软件包从“发行版”更改为“调试”,它就可以了。


如果您要应用任何插件。 然后,确保在模块Gradle文件(通常是 app/build.gradle )中,确保 在文件底部 添加 apply plugin 行以启用Gradle插件。

例如


对我有用的东西。

  1. 转到您应用的android文件夹。
  2. 运行./gradlew clean

尝试通过 :app:installDebug 。 如果有效,则与Android Studio的缓存有关。 我删除了项目中的 .gradle/ 文件夹,它可以正常工作。


就我而言

apply plugin: 'com.google.gms.google-services'

build.gradle 文件的底部,并在 defaultConfig 中将 multiDexEnabled true 设置 multiDexEnabled true 。 然后运行即可。


就我而言,这是由于我的库未配置为“ android”。 例如, apply plugin:'java' 而不是 apply plugin:'com.android.library'


就我而言,问题是由于某些包装中的大写字母。


我的项目在 build.gradle 文件(1.7和1.8)中使用了具有异构Java兼容版本的外部库。 我通过为lib和app项目使用相同的版本来修复它。 就我而言:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
    }

我遇到了同样的问题。
首先从项目位置 删除 build 文件夹(您可以通过android studio或使用资源管理器访问它),然后 build 项目。


我遇到了同样的问题,我清理了项目,导致其他一些问题无法清理,因此我手动删除了dir'build',这样就可以清理好了,然后为我运行。


我遇到了同样的问题,这是由不相同版本的Google Analytics(分析)和Firebase引起的。 我使用了 'com.google.gms:google-services:3.1.0' ,然后添加了以下依赖项:

compile 'com.google.android.gms:play-services-gcm:10.2.6'
compile 'com.google.firebase:firebase-crash:10.0.1'

因此,将Firebase版本更改为10.2.6可以解决此问题。

compile 'com.google.android.gms:play-services-gcm:10.2.6'
compile 'com.google.firebase:firebase-crash:10.2.6'

由于某些原因,@ ChintanSoni的答案无效。 我尝试手动删除 build 文件夹,但由于某些进程正在使用它们而无法删除某些文件。 清理和重新构建项目没有帮助,所以我打开了 task manager ,选择了 JAVA(TM) Platform SE binary 然后按了“结束任务”。

然后,我尝试再次运行该项目,并且开始编译正常。


请在build.gradle中的android内部添加此块

dexOptions { preDexLibraries = false }


这个问题有很多答案,但是,如果您还没有解决错误,这可能会起作用:

有时我们会从Google产品/ API导入不同的版本,因此,请尝试组织您的gradle文件来解决以下问题: Mixing versions 警告


首先,构建->清理项目->再次重建它。

如果它不起作用,则在 build.gradle ,将 multiDexEnabled 设置为 true

例如:

defaultConfig {
    applicationId "com.example.myapplication"
    minSdkVersion 21
    targetSdkVersion 27
    multiDexEnabled true
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner"
}
