Ionic app build issue

I am new to ionic. I have developed sample application ionic.
When I try to execute below command it gives gradle error.
$ ionic build android
Below is the build error:
Error: /home/myapp/platforms/android/gradlew: Command failed with exit code 1 Error output:
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred starting process 'Gradle build daemon'
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
Gradle version is 3.3

Android SDK and Android Studio located in /usr/local/ folder
You will either have to move it to your home directory (that involves reinstall).
Or run ionic build commands with sudo
sudo ionic build android
You could technically change permissions of the specific sdk and studio folders but it is not advisable especially in /usr directory.

Unable to build Android using ionic

I am trying to setup Ionic framework for developing android apps on my mac but I am having some problems in building android apps.
I have followed following procedure for installing ionic :
Run: "sudo npm install -g cordova"
Run: "sudo npm install -g ionic"
Run: “android” then install the following packages
Tools: Andoird SDK Tools, Android SDK Platform-tools, Android SDK Build-tools
Android 4.4.2 (API 19)
Extras: Android Support Library
My .bash file is like this :
export JAVA_HOME=$(/usr/libexec/java_home)
export PATH=${JAVA_HOME}/bin:$PATH
export PATH=${PATH}:~/Library/Android/sdk/tools:~/Library/Android/sdk/platform-tools
This is the error I am getting while building android app :
You have been opted out of telemetry. To change this, run: cordova telemetry on.

Please install Android target: "android-23".
Hint: Open the SDK manager by running: /Users/coderahul/Library/Android/sdk/tools/android
You will require:
1. "SDK Platform" for android-23
2. "Android SDK Platform-tools (latest)
3. "Android SDK Build-tools" (latest)

This happened to me just type this in your terminal "/Users/coderahul/Library/Android/sdk/tools/android" and proceed with the steps to download the sdk for android-23.
This happens because your device is using the higher version of OS than the sdk version
