前言

最近在使用Android Studio 3.1.2導(dǎo)入以前的項(xiàng)目遇到一些坑，借此機(jī)會(huì)把相關(guān)處理方法分享出來(lái)。

下面以導(dǎo)入Android Studio2.3.3項(xiàng)目為例：

在此之前先建議你用Android Studio 3.1.2創(chuàng)建一個(gè)新的項(xiàng)目，看看有哪些變化，這對(duì)你很有幫助。

修改app/build:gradle

修改compileSdkVersion和buildToolsVersion

修改前，

compileSdkVersion 23buildToolsVersion '25.0.0'

修改后：

compileSdkVersion 27buildToolsVersion '27.0.3'

其中buildToolsVersion 是在Android Studio 3.0之后取消了，你可以保留也可以注釋掉，在defaultConfig方法中將targetSdkVersion 為27并增加一下代碼。

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

修改依賴關(guān)鍵字 compile(implementation/api),provided(compileOnly),apk(runtimeOnly)

修改前：

dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile name: 'SMSSDK-3.0.0', ext: 'aar' compile name: 'SMSSDKGUI-3.0.0', ext: 'aar' compile 'com.android.support:appcompat-v7:23.4.0' compile 'com.android.support:design:23.4.0' compile 'com.android.support:recyclerview-v7:23.4.0' compile 'de.hdodenhof:circleimageview:2.1.0' compile 'com.youth.banner:banner:1.4.9' compile 'com.facebook.fresco:fresco:0.13.0' compile 'com.squareup.okhttp3:okhttp:3.4.1' compile 'com.google.code.gson:gson:2.8.0' compile 'com.github.bumptech.glide:glide:3.7.0' compile 'com.android.support:support-v4:23.4.0' compile 'com.foamtrace:photopicker:1.0' compile 'com.github.chrisbanes.photoview:library:1.2.4' compile 'com.android.support.constraint:constraint-layout:1.0.2' testCompile 'junit:junit:4.12' compile project(':ZXingAndroid') compile 'com.google.zxing:core:3.3.1'}

修改后：

dependencies { implementation fileTree(include: ['*.jar'], dir: 'libs') implementation 'com.android.support:appcompat-v7:27.1.1' implementation 'com.android.support.constraint:constraint-layout:1.1.1' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.2' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' implementation name: 'SMSSDK-3.0.0', ext: 'aar' implementation name: 'SMSSDKGUI-3.0.0', ext: 'aar' implementation 'com.android.support:appcompat-v7:27.1.1' implementation 'com.android.support:design:27.1.1' implementation 'com.android.support:recyclerview-v7:27.1.1' implementation 'de.hdodenhof:circleimageview:2.1.0' implementation 'com.youth.banner:banner:1.4.9' implementation 'com.facebook.fresco:fresco:0.13.0' implementation 'com.squareup.okhttp3:okhttp:3.4.1' implementation 'com.google.code.gson:gson:2.8.0' implementation 'com.github.bumptech.glide:glide:3.7.0' implementation 'com.android.support:support-v4:27.1.1' implementation 'com.foamtrace:photopicker:1.0' implementation 'com.github.chrisbanes.photoview:library:1.2.4' implementation 'com.android.support.constraint:constraint-layout:1.0.2' implementation 'com.google.zxing:core:3.3.1'}

修改項(xiàng)目下的XXX（項(xiàng)目名）/build:gradle

修改前：

<code class="language-html">// 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:2.3.3'   // NOTE: Do not place your application odependencies here; they belong  // in the individual module build.gradle files } }  allprojects { repositories {  jcenter()  maven {url "https://jitpack.io" } } }  task clean(type: Delete) { delete rootProject.buildDir }</code>

修改后：

// Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { google() jcenter() } dependencies { classpath 'com.android.tools.buiwld:gradle:3.1.3'//與AS版本號(hào)保持一致  // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files }} allprojects { repositories { google() jcenter() maven { url "https://jitpack.io" } }} task clean(type: Delete) { delete rootProject.buildDir}

repositories方法中都增加了google()，build:gradle改和當(dāng)前AS版本號(hào)一致。

修改gradle-wrapper.properties

修改前：

#Tue Aug 29 08:07:34 CST 2017distributionBase=GRADLE_USER_HOMEdistributionPath=wrapper/distszipStoreBase=GRADLE_USER_HOMEzipStorePath=wrapper/distsdistributionUrl=https/://services.gradle.org/distributions/gradle-3.3-all.zip

修改后：

#Tue Aug 29 08:07:34 CST 2017distributionBase=GRADLE_USER_HOMEdistributionPath=wrapper/distszipStoreBase=GRADLE_USER_HOMEzipStorePath=wrapper/distsdistributionUrl=https/://services.gradle.org/distributions/gradle-4.4-all.zip

主要修改了：distributionUrl=https/://services.gradle.org/distributions/gradle-4.4-all.zip

這里告一段落，上面都改好之后同步項(xiàng)目（sync）。我為什么建議你把上面的都改好之后再同步，這樣省事兒，剛開(kāi)始的時(shí)候我也是改一點(diǎn)同步一下，問(wèn)題多且很浪費(fèi)時(shí)間，如果其中有些問(wèn)題沒(méi)能解決就容易走偏。

如果報(bào)錯(cuò)：

<code class="language-html">Error: java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2Exception: AAPT2 error: check logs for details </code>

修改gradle.properties，增加如下代碼
