Android Studio Tips（部分问题可能集成ionic才会出现）

导入项目时进度条卡住不动

查看gradle版本：

C:\Users\用户名\.gradle\wrapper\dists\gradle-1.XX-all

存放位置：

C:\Users\用户名\.gradle\wrapper\dists\gradle-1.XX-all\3jdgemv0iv8uqohg3kcp2o88r1\gradle-1.XX-all.zip

手工下载gradle
​​​https://downloads.gradle.org/distributions/gradle-2.2.1-all.zip​​​​https://downloads.gradle.org/distributions/gradle-2.4-all.zip​​

放到对应位置
C:\Users\king.gradle\wrapper\dists\gradle-x.x.x-all\c64ydeuardnfqctvr1gm30w53
重启android studio ， 自动解压。

或者单击：
android studio工具栏 => Sync Project Gradle Files

另外网上有一种处理方式，我没有测试：

java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0

修改build.gradle Module:app
把

android {
    compileSdkVersion 23
    buildToolsVersion "24.0.0"

改为

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

或者在这里修改：

Android Studio菜单异常，不能正常新建Project

删除 C:\Users\用户名.AndroidStudio1.5
其中.AndroidStudio1.5可能不是这个名字。

Execution failed for task:’:transformClassesWithDexForDebug’.

修改：build.gradle

defaultConfig {

        multiDexEnabled true   加这一句
        versionCode cdvVersionCode ?: Integer.parseInt("" + privateHelpers.extractIntFromManifest("versionCode") + "0")
        applicationId privateHelpers.extractStringFromManifest("package")

        if (cdvMinSdkVersion != null) {
            minSdkVersion cdvMinSdkVersion
        }

    }

Error:Execution failed for task ‘:transformClassesWithJarMergingForDebug’.

> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/annotation/BinderThread.class

删除：

Error:Execution failed for task ‘:transformClassesWithMultidexlistForDebug’.

> java.io.IOException: Can't read [D:\Documents\adt-bundle-windows-x86_64-20140702\sdk\build-tools\19.1.0\multidex\shrinkedAndroid.jar] (No such file or directory)

修改build.gradle

buildToolsVersion ‘23.0.3’

minSdkVersion 错误

Error:Execution failed for task ':processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 18 declared in library [android:cloudkit-release-9.0.0.999:unspecified] D:\Documents\WhrSmartV1\ionic\platforms\android\build\intermediates\exploded-aar\android\cloudkit-release-9.0.0.999\unspecified\AndroidManifest.xml
  Suggestion: use tools:overrideLibrary="com.yunos.cloudkit" to force usage

修改：

为18

A problem occurred evaluating root project ‘android’. Cannot execute null+null

Gradle sync failed

Could not download gradle-core.jar (com.android.tools.build:gradle-core:2.2.1): No cached version available for offline mode
Consult IDE log for more details (Help | Show Log)

把Settings-Build、Execution、Deployment-Gradle 下的Offline work的钩去掉，重启Android Studio

安装platform-tools提示checksum错误

处理方式1：
clear cache-for htts to http-重试下载
处理方式2：
手工下载，放到sdk/platform-tools

Unable to resolve dependency for ‘:app@debug/compileClasspath’: Could not resolve com.android.support:appcompat-v7:26.1.0

在build.gradle 写在 dependencies 里加上：

compile "com.android.support:support-core-utils:27.1.0"

Unable to resolve dependency for ‘:@debug/compileClasspath’: Could not resolve project :CordovaLib.

把这种依赖方式

debugCompile project(path: "CordovaLib", configuration: "debug")
releaseCompile project(path: "CordovaLib", configuration: "release")

改成:

implementation project(':CordovaLib')

Caused by: java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details

在Terminal使用​​gradle compileDebug --stacktrace -info​​打印详细错误

​​Minimum supported Gradle version is 4.1. Current version is 2.13. If using the gradle wrapper, try editing the distribution Url in D:\Documents\WhrSmartV1\ionic\platforms\android\gradle\wrapper\gradle-wrapper.properties to gradle-4.1-all.zip​​

提示CurrentVersion is 2.13，但gradle-wrapper.properties里值已经是gradle-4.1-all.zip
修改系统变量的PATH，指向新版本的gradle，如：

C:\Users\用户名\.gradle\wrapper\dists\gradle-4.1-all\6aljcho5ti94cio10aoqa5qqs8\gradle-4.1\bin;
