gradlew build freezing at mergeDebugResources

问题

I build debug app use gradlew as in google tutorial https://developer.android.com/training/basics/firstapp/running-app.html

I was created project use

android create project --target 2 -g -v 2.9--name myAppName --path ./MyAppDirectory --activity MyActivity --package com.mypackage

and this is my build.gradle file

buildscript {
repositories {
    mavenCentral()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.5.0'
}
}

apply plugin: 'android'

android {
    compileSdkVersion 'Google Inc.:Google APIs:23'
    buildToolsVersion '23.0.2'

buildTypes {
    release {
        //runProguard false
          //minifyEnabled true
        proguardFile getDefaultProguardFile('proguard-android.txt')
    }
}
}

I build debug app use command

$ ./gradlew assembleDebug

and building is freezing at 40% as

    :preBuild UP-TO-DATE
:preDebugBuild UP-TO-DATE
:checkDebugManifest
:prepareDebugDependencies
:compileDebugAidl UP-TO-DATE
:compileDebugRenderscript UP-TO-DATE
:generateDebugBuildConfig UP-TO-DATE
:generateDebugAssets UP-TO-DATE
:mergeDebugAssets UP-TO-DATE
:generateDebugResValues UP-TO-DATE
:generateDebugResources UP-TO-DATE
:mergeDebugResources

回答1:

Most likely you have a 64bit system and still some 32bits are missing for android development.

If you're running on a 64bit-Ubuntu system, see 32-bit-libs for Ubuntu 64-bit Android Development for further details.

If you're running on a 64bit-Fedora system, see installing-android-sdk-on-64-bit-fedora/ for further details.

Fixed it by installing the libraries

sudo apt-get install lib32z1

sudo apt-get install zlib1g:i386
