I was trying to build an Ionic2 app with Android platform on my Win 7 (32 bt) system.
I ran the ionic build android
command in the CLI and the following error occurred :
...ionic build android

Starting a new Gradle Daemon for this build (subsequent builds will be faster).
FAILURE: Build failed with an exception.
* What went wrong:
Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at https://docs.gradle.org/2.14.1/userguide/gradle_daemon.html
Please read the following process output to find out more:
-----------------------
Error occurred during initialization of VM
Could not reserve enough space for 2097152KB object heap
Then as suggested I read the ' https://docs.gradle.org/2.14.1/userguide/gradle_daemon.html ' and created the gradle.properties file with the following
org.gradle.daemon=true
The error still persists with the same result !!!
What is going wrong ?? Please help .
Found the solution after a hour long R&D.
Basically as per ' https://cordova.apache.org/docs/en/latest/guide/platforms/android/ ' - As of cordova-android@4.0.0, Cordova for Android projects are built using Gradle. Earlier it was built using Apache Ant.
Now Gradle looks for latest Android SDK. When I removed the android platform and added again with ionic platform add android
command - the CLI listed that the latest Android SDK ( in my case it was SDK 24 ) was not installed.
I installed the required SDK version using Android SDK Manager and subsequent add of Android Platform along with the cordova plugin smoothly installed without any error.
The CLI printed the following -
..ionic plugin add onesignal-cordova-plugin
Fetching plugin "onesignal-cordova-plugin" via npm
Installing "onesignal-cordova-plugin" for android
ANDROID_HOME=C:\Program Files (x86)\Android\android-sdk
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_121
Subproject Path: CordovaLib
Incremental java compilation is an incubating feature.
:clean

BUILD SUCCESSFUL

Try using cordova platform add https://github.com/apache/cordova-android
Ive had to start using this command ever since updating Ionic.
