Android Gradle配置

编译加速

在gradle.properties中配置

1 org.gradle.configureondemand=true               #demand2 org.gradle.daemon=true                          #单独的守护进程3 org.gradle.parallel=true                        #串行编译4 org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8                  #内存设置

build.gradle中添加

1 lintOptions { 2     disable 'InvalidPackage', 'ContentDescription' 3     abortOnError false 4 } 5  6 dexOptions { 7     jumboMode = true 8     preDexLibraries = false 9     javaMaxHeapSize "4g"10 }

 

只支持特定abi

abiFilters配置，可配合Product flavors使用。

1 ndk {2     abiFilters "armeabi", "x86"3 }

 

依赖库版本管理

在项目工程build.gradle中统一定义

1 ext { 2     // Sdk and tools 3     minSdkVersion = 10 4     targetSdkVersion = 22 5     compileSdkVersion = 23 6     buildToolsVersion = '23.0.2' 7  8     // App dependencies 9     supportVersion = '23.4.0'10 }

在模块工程build.gradle使用

1 android { 2     compileSdkVersion rootProject.ext.compileSdkVersion 3     buildToolsVersion rootProject.ext.buildToolsVersion 4 } 5  6 dependencies { 7     // App's dependencies, including test 8     compile "com.android.support:appcompat-v7:$rootProject.supportVersion" 9     compile "com.android.support:cardview-v7:$rootProject.supportVersion"10     compile "com.android.support:design:$rootProject.supportVersion"11     compile "com.android.support:recyclerview-v7:$rootProject.supportVersion"12     compile "com.android.support:support-v4:$rootProject.supportVersion"13 }

 

依赖库多版本解决

1 configurations.all {2     resolutionStrategy.force "com.android.support:support-v4:$rootProject.supportVersion"3 }

 

签名信息

项目中添加sign.properties

1 keystore=[path to]\release.keystore2 keystore.password=*********3 keyAlias=***********4 keyPassword=********

在build.gradle读取文件并设置签名信息

1 if(new File(project.property("sign.properties")).exists()) { 2  3     Properties props = new Properties() 4     props.load(new FileInputStream(file(project.property("sign.properties")))) 5  6     signingConfigs { 7         release { 8             storeFile file(props['keystore']) 9             storePassword props['keystore.password']10             keyAlias props['keyAlias']11             keyPassword props['keyPassword']12         }13     }14 }
