我的戴尔inspiron N4010笔记本电脑采用英特尔酷睿i5 CPU M 480 @ 2.67GHz,4GB内存,500GB硬盘运行ubuntu 16.04LTS - 64位操作系统。我一直在Android Studio 1.5+版本中开发Android应用程序。现在已迁移到Android Studio 2.1.2。在我的笔记本电脑中以前版本的AS中,一切都很顺利。
在最新版本中构建应用程序太慢;只需在编辑xml文件时,需要30秒到1.5分钟才能构建。如果我对Java文件进行了任何更改,那么构建时间将达到10分钟。
所以,我将硬盘格式化为ext4并安装了ubuntu 16.04(单一操作系统) - 500GB完全...
下载并安装了Android Studio 2.1.2和Oracle jdk 8.每次更改任何java文件时,还需要10分钟。
这是我的app(模块)gradle文件:

项目级gradle文件:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
我试图从互联网上搜索并找到了一些解决方案。这是我的gradle.properties文件:
org.gradle.jvmargs=-Xmx11000m -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
org.gradle.parallel=true
org.gradle.daemon=true
还禁用了一些插件:
CVS integration
Git
Github
Google cloud tools
Subversion Integration
通过文件更改以下设置为选中标记 - >设置 - >构建,执行,部署--->
Global Gradle settings- offline work
Compiler- Compile independent modules
- Make project automatically
- command line options: --offline --profile --parallel
- Use in-process build
- Configure on demand
Instant run - unchecked(disabled) everything in that tab.
还是太慢了...... 8到10分钟! 因此决定通过命令行构建;关闭每个应用程序甚至Android工作室,Firefox和一切。
./ gradlew assembleDebug --profile - 离线 第一次,它说后续构建会更快。现在建造时间缩短到3到4分钟......

同样的项目在具有相同配置的另一台HP笔记本电脑上运行顺畅(i5,4GB RAM,500GB HDD,ubuntu 16.04-64位操作系统),相同的工具:Android Studio 2.1.2,oracle jdk-8;只需几秒钟即可在该机器上构建和运行。
但对我来说,整个系统都悬而未决;从Android Studio或终端构建时无法执行任何操作。
请帮帮我们......
