ionic build Android | error: No installed build tools found. Please install the Android build tools

Question

When I run ionic build android command in root of ionic project, I am getting this error:

FAILURE: Build failed with an exception.

Answer 1

This works for me! be careful with the new java versions because they cause error, check that you have everything installed and in your specific directory,

I did not use openJDK

export JAVA_HOME="/usr/lib/jvm/java-8-jdk" \
&& export PATH=$JAVA_HOME/bin:$PATH \
&& export ANDROID_HOME=$HOME/Android/Sdk \
&& export PATH=${PATH}:${ANDROID_HOME}/tools \
&& export PATH=${PATH}:${ANDROID_HOME}/platform-tools \
&& export GRADLE_HOME=/usr/share/java/gradle/bin/gradle \
export PATH=$PATH:$GRADLE_HOME/bin

Answer 2

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

export ANDROID_HOME=~/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

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 file.
4. Restart your terminal

Adding to bash process for different systems

I Search this problem for days.... I hope it will be usefull

FINAL SOLUTION: (I assume that you have installed Oracle-JDK and ANDROID)

open /etc/environment with

 sudo nano /etc/environment


PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/shoniisra/Android/Sdk/tools:/home/shoniisra/Android/Sdk/platform-tools:/home/shoniisra/Android/Sdk/build-tools:/home/shoniisra/Android/Sdk:/home/shoniisra/android-studio/bin"
JAVA_HOME="/home/shoniisra/java/jdk1.8.0_231"
ANDROID_HOME="/home/shoniisra/Android/Sdk/build-tools/29.0.2"
ANDROID_SDK_ROOT="/home/shoniisra/Android/Sdk"
ANT_HOME="/home/shoniisra/ant/apache-ant-1.9.14"

Save and exit (CTRL+o CTRL+X)

Reload file source /etc/environment

If you recently installed Android you should accept some licences

cd ~/Android/Sdk/tools/bin/

Execute sdkmanager:

./sdkmanager --licenses

Then Accept all, and Finally generate your APK

cd {yourproyect}
sudo ionic cordova build android

Answer 4

This issue also occur if you do an upgrade to you cordova installation.

Check if your log error has something like:

Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=undefined (recommended setting) <-------------
ANDROID_HOME=/{path}/android-sdk-linux (DEPRECATED)
Using Android SDK: /usr/lib/android-sdk
Starting a Gradle Daemon (subsequent builds will be faster)

In such case, just change ANDROID_HOME to ANDROID_SDK_ROOT in your ~/.bashrc or similar config file.

Where before was:

export ANDROID_HOME="/{path}/android-sdk-linux"

Now is:

export ANDROID_SDK_ROOT="/{path}/android-sdk-linux"

Don't forget source it: $ . ~/.bashrc after edition.

Answer 5

Type android on your command line and install "Android SDK Build-tools"

Answer 6

This is very irritating error and i wasted my almost 9 hours to solve this.

Steps to solve:

Notice **ANDROID_HOME** while you run **ionic cordova build android** . command i. for example in my case it was pointing to some other android sdk which i uninstalled and then it started pointing to right sdk.
**In my case i uninstalled :**

brew cask uninstall android-sdk
brew cask uninstall android-platform-tool


then i ran **ionic cordova build android**

> cordova build android
ANDROID_HOME=/Users/anand/Library/Android/sdk
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_172.jdk/Contents/Home


Then it might say lineces not accepted then run below command :

cd /Users/Android/sdk/tools/bin/
then run ./sdkmanager --licenses
accepts all with y option


Then it might say unable to download jars then go to platform android and build.gradle

and search for buildscript and inside that reverse the order 


repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }

Thats it . Enjoy huh
