android studio 导入别人项目 gradle很久问题

  1.经常从github上面下载一个Android studio 项目,结果出现gradle很久很久,久到android studio 崩了 还是没好~,这里我提一下自己的解决办法:

先 修改 gradle\wrapper\gradle-wrapper.properties 改为自己的版本

distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip

       我们这里随便从网上下载一个项目,看一下他的目录结构:

,然后我们打开一个 我们自己新建的一个项目或者一个在自己电脑编译好的项目,目录结构如下:

我们先打开自己项目和别人项目的build.gradle文件,如下:

自己的:

 // Top-level build file where you can add configuration options common to all sub-projects/modules.

 buildscript {
     repositories {
         jcenter()
     }
     dependencies {
         classpath 'com.android.tools.build:gradle:2.2.0'

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

 allprojects {
     repositories {
         jcenter()
     }
 }

 task clean(type: Delete) {
     delete rootProject.buildDir
 }

，别人的:

 // Top-level build file where you can add configuration options common to all sub-projects/modules.

 buildscript {
     repositories {
         jcenter()
     }
     dependencies {
         classpath 'com.android.tools.build:gradle:2.2.2'

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

 allprojects {
     repositories {
         jcenter()
     }
 }

 task clean(type: Delete) {
     delete rootProject.buildDir
 }

1.将别人的 classpath  改成与自己相同的：classpath 'com.android.tools.build:gradle:2.2.0'

2.然后我们打开别人项目的当前文件;

打开文件如下,

 apply plugin: 'com.android.application'

 android {
     compileSdkVersion 25
     buildToolsVersion "25.0.0"
     defaultConfig {
         applicationId "com.kevin.tech.bottomnavigationbarforandroid"
         minSdkVersion 17
         targetSdkVersion 25
         versionCode 1
         versionName "1.0"
         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
     }
     buildTypes {
         release {
             minifyEnabled false
             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
         }
     }
 }

 dependencies {
     compile fileTree(include: ['*.jar'], dir: 'libs')
     androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
         exclude group: 'com.android.support', module: 'support-annotations'
     })
     compile 'com.android.support:appcompat-v7:25.0.1'
     testCompile 'junit:junit:4.12'
     compile 'com.ashokvarma.android:bottom-navigation-bar:1.3.1'
 }

，我们看一下我们自己项目的这个文件内容:

 apply plugin: 'com.android.application'

 android {
     compileSdkVersion 25
     buildToolsVersion "25.0.2"
     defaultConfig {
         applicationId "dyk.viewpagerdemo"
         minSdkVersion 19
         targetSdkVersion 25
         versionCode 1
         versionName "1.0"
         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
     }
     buildTypes {
         release {
             minifyEnabled false
             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
         }
     }
 }

 dependencies {
     compile fileTree(dir: 'libs', include: ['*.jar'])
     androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
         exclude group: 'com.android.support', module: 'support-annotations'
     })
     compile 'com.android.support:appcompat-v7:25.3.1'
     testCompile 'junit:junit:4.12'
 }

2.我们需要修改将下图的版本修改成自己的编译版本:

然后,导入后就可以了
