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

Best Solution

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.
