in ~/.profile i have:

export PATH=$PATH:/opt/android-sdk/tools

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

export PATH=$PATH:/opt/node/bin

export JAVA_HOME=/usr/lib/jvm/default-java

export ANDROID_HOME=/opt/android-sdk

$PATH is:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/android-sdk/tools:/opt/android-sdk/platform-tools:/opt/node/bin

Important issue:

in file: /home/javad/Desktop/javadApp/platforms/android/CordovaLib/cordova.gradle | line 38:

String[] getAvailableBuildTools() {     def buildToolsDir = new File(getAndroidSdkDir(), "build-tools")     buildToolsDir.list()         .findAll { it ==~ /[0-9.]+/ }         .sort { a, b -> compareVersions(b, a) } } 

just returned /opt/android-sdk/build-tools !!!

in /opt/android-sdk/build-tools folder i have:

android-5.1 folder that extract from: https://dl.google.com/android/repository/build-tools_r22-linux.zip

Answer 1

I fix this by downloading sdk package called platform-tools and buid-tools using sdkmanager. You can use sdkmanager.exe or if you are using SDK CLI, go to ~\AppData\Local\Android\sdk\tools\bin and run this command:

sdkmanager "platform-tools" "platforms;android-26" 

or

sdkmanager "build-tools;27.0.3" 

or both

After that you should be able to run ionic cordova run android or ionic build android.

Note: globalize sdkmanager command by adding ~\AppData\Local\Android\sdk\tools and ~\AppData\Local\Android\sdk\tools\bin to your environment variable.

For me running these three commands fix the issue on my Mac:

export ANDROID_HOME=~/Library/Android/sdk export ANDROID_SDK_ROOT=~/Library/Android/sdk export PATH=${PATH}:${ANDROID_HOME}/tools export PATH=${PATH}:${ANDROID_HOME}/platform-tools 

For ease of copying here's one-liner

export ANDROID_HOME=~/Library/Android/sdk && export PATH=${PATH}:${ANDROID_HOME}/tools && export PATH=${PATH}:${ANDROID_HOME}/platform-tools && export ANDROID_SDK_ROOT=~/Library/Android/sdk 

To add Permanently

Follow these steps:

1. Open the .bash_profile file in your home directory (for example, /Users/your-user-name/.bash_profile) in a text editor.
2. Add export PATH="The above exports here" to the last line of the file, where your-dir is the directory you want to add.
3. Save the .bash_profile or .zshrc file.
4. Restart your terminal. Or run source ~/.bash_profile or source ~/.zshrc depending on your terminal settings.

Adding to bash process for different systems
