>在/ opt / android-sdk-linux中找不到哈希字符串为“ android-26”的目标 [英] > Failed to find target with hash string 'android-26' in: /opt/android-sdk-linux

问题描述

• Ubuntu 16.04


• / opt / android-sdk-linux上的android-sdk


• 配置的android home出口ANDROID_HOME = / opt / android-sdk-linux /）


• / opt / android-sdk-linux /

中没有其他工具文件夹

我的gradle文件：

  android {
 compileSdkVersion 26 
 buildToolsVersion 21.1.0 
 defaultConfig {
 applicationId hu.prject.sandbox.sample 
 minSdkVersion 21 
 targetSdkVersion 26 
 versionCode 1 
 versionName 1.0 
 testInstrumentationRunner android.support.test.runner.AndroidJUnitRunner 
} 
 buildTypes {
 release {
 minifyEnabled false 
 proguardFiles getDefaultProguardFile（'proguard-android.txt'），'proguard-rules.pro'
} 
} 
} 
  

在项目中运行 ./ gradelew clean build 时文件夹，我得到以下输出：

启动Gradle守护进程（后续构建会更快）
准备安装Android SDK Build-Tools 21.1。
准备安装Android SDK Build-Tools 21.1。
完成安装Android SDK Build-Tools 21.1
在/opt/android-sdk-linux/build-tools/21.1.0中安装Android SDK Build-Tools 21.1
安装Android SDK Build-Tools 21.1已完成。
正在准备安装Android SDK平台26。
准备安装Android SDK Platform 26。
完成安装Android SDK平台26
在/ opt / android-sdk-linux / platforms / android-26中安装Android SDK平台26
安装Android SDK平台26完成。 / p>

失败：构建失败，出现异常。

出了什么问题：
配置项目时发生问题'：app'。

在以下位置找不到带有哈希字符串'android-26'的目标：/ opt / android-sdk-linux

重要：在我的情况下，
没有android studio，没有ui，只有CLI

存在android-26文件夹，其内容位于/ opt / android-sdk-linux / platforms /

解决方案

1. 从中删除所有以前的android sdk文件/ opt /


2. cd / opt&& wget https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip



3. 解压缩sdk-tools-linux-3859397.zip -d android-sdk-linux




4. nano /etc/profile.d/android.sh

粘贴以下行：

  export ANDROID_HOME = / opt / android-sdk-linux 
 export PATH = $ ANDROID_HOME / tools：$ ANDROID_HOME / platform-tools：$ PATH 
  

5. source / etc / profile

检查android home：

  echo $ ANDROID_HOME 
  

/ opt / android-sdk-linux中的


6. 
   
   

   tools / bin / sdkmanager --update

   
   
   

   tools / bin / sdkmanager platforms; android-26 build-tools; 26.0。 2 extras; google; m2repository extras; android; m2repository

   
   
   

   tools / bin / sdkmanager- -许可证

在这一点上可能就足够了，构建可以正常工作...

但是在我的情况下，缺少一些依赖项，并与

进行检查

tools / bin / sdkmanager --list

使用缺少依赖项
tools / bin / sdkmanager extras; m2repository; com; android; support; constraint; constraint-layout; 1.0.0-alpha9

tools / bin / sdkmanager extras; m2repository; com; android; support; constraint; constraint-layout-solver; 1.0.0-alpha9

在这些构建成功之后

感谢NinjaCoder提供有关构建工具版本的帮助

• Ubuntu 16.04
• android-sdk at /opt/android-sdk-linux
• android home confugired (export ANDROID_HOME="/opt/android-sdk-linux/")
• there is no additional tools folder in /opt/android-sdk-linux/

my gradle file:

android {
    compileSdkVersion 26
    buildToolsVersion "21.1.0"
    defaultConfig {
        applicationId "hu.prject.sandbox.sample"
        minSdkVersion 21
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

when run ./gradelew clean build in the project folder, I got this output:

Starting a Gradle Daemon (subsequent builds will be faster) Preparing "Install Android SDK Build-Tools 21.1". "Install Android SDK Build-Tools 21.1" ready. Finishing "Install Android SDK Build-Tools 21.1" Installing Android SDK Build-Tools 21.1 in /opt/android-sdk-linux/build-tools/21.1.0 "Install Android SDK Build-Tools 21.1" complete. Preparing "Install Android SDK Platform 26". "Install Android SDK Platform 26" ready. Finishing "Install Android SDK Platform 26" Installing Android SDK Platform 26 in /opt/android-sdk-linux/platforms/android-26 "Install Android SDK Platform 26" complete.

FAILURE: Build failed with an exception.

What went wrong: A problem occurred configuring project ':app'.

Failed to find target with hash string 'android-26' in: /opt/android-sdk-linux

IMPORTANT: in my case no android studio, no ui, only CLI

There is android-26 folder exist with content at /opt/android-sdk-linux/platforms/

解决方案

1. remove all previous android sdk files from /opt/
2. cd /opt && wget https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip

3. unzip sdk-tools-linux-3859397.zip -d android-sdk-linux

4. nano /etc/profile.d/android.sh

paste this lines:

export ANDROID_HOME="/opt/android-sdk-linux"
export PATH="$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$PATH"

5. source /etc/profile

check android home:

echo $ANDROID_HOME

6. in /opt/android-sdk-linux

   tools/bin/sdkmanager --update

   tools/bin/sdkmanager "platforms;android-26" "build-tools;26.0.2" "extras;google;m2repository" "extras;android;m2repository"

   tools/bin/sdkmanager --licenses

maybe enough at this point and the build will work...

but in my case missing some dependency, and check with

tools/bin/sdkmanager --list

update with the missing dependencies tools/bin/sdkmanager "extras;m2repository;com;android;support;constraint;constraint-layout;1.0.0-alpha9"

tools/bin/sdkmanager "extras;m2repository;com;android;support;constraint;constraint-layout-solver;1.0.0-alpha9"

after these build success
