由于Android Studio中的Gradle问题，无法启动Android应用

Question

我正在尝试使用我的Samsung /虚拟机编译我的android项目，但出现以下错误：

    Error:Execution failed for task ':app:dexDebug'.
    > com.android.ide.common.process.ProcessException:         
    org.gradle.process.internal.ExecException: Process 'command
    '/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home/bin/java'' 
    finished with non-zero exit value 2

我在任何地方都找不到答案，请问有什么想法吗？

Answer 1

尝试在gradle中启用多dex文件支持。

将以下代码添加到您的build.gradle

defaultConfig {        
    // Enabling multidex support.
    multiDexEnabled true
}

Answer 2

据我所知，该错误与JDK或gradle本身无关，并且可能有很多原因，例如：

1. 超过65k方法限制。

您可以尝试在gradle中启用Multi dex支持：

defaultConfig {        
    // Enabling multidex support.
    multiDexEnabled true
}

或者只是尝试通过删除一些不必要的库来最小化应用程序。

2. 一些jar或库文件包含在多个位置。

为此，请在Android Studio中执行以下命令：

gradlew -q dependencies yourProjectName_usually_app:dependencies --configuration compile

搜索列出的依存关系中的重复项（标有星号*）并将其删除。

Answer 3

classpath 'com.android.tools.build:gradle:1.3.0' -> Should be 1.3.1

buildToolsVersion '23.0.0' -> Should be '23.0.2'

还添加

 defaultConfig {        
// Enabling multidex support.
multiDexEnabled true

}

清理您的代码并重新构建

Answer 4

For me the problem was, i had put a unnecessary compile library code in build.gradle

dependencies {
    compile 'com.google.android.gms:play-services:7.5.0'
}
which was causing over 65k methods, so removed it,gradle sync, cleaned project, and then ran again and then this error stopped. I needed just maps and gcm so i put these lines and synced project

compile 'com.google.android.gms:play-services-gcm:7.5.0'
compile 'com.google.android.gms:play-services-location:7.5.0'

Hi people i again encountered this problem and this time it was because of changing build tools version and it really required me to enable multidex..so i added these my app's build.gradle file..

defaultConfig {
    applicationId "com.am.android"
    minSdkVersion 13
    targetSdkVersion 23
    // Enabling multidex support.
    multiDexEnabled true
}

dexOptions {
    incremental true
    javaMaxHeapSize "2048M"
    jumboMode = true
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:multidex:1.0.1'
}
And create a class that extends Application class and include this method inside the class..

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}
also include in OnCreate method too

@Override
public void onCreate() {
    MultiDex.install(this);
    super.onCreate();
}
