Unable to Build Android App

rminor · January 29, 2017, 11:43pm

Hello,

I am receiving errors (outlined below) when trying to build the Android version of my app. I am using a MacBook Pro with OSX 10.12.2. I tried to remove and add the Android platform but that didn’t work. It seems like something is wrong with my JAVA version but I am not sure how to debug or fix that. Any help is appreciated. Here is my output from the terminal when I run “ionic build android”:

Running command: /Users/ryanminor/Code/patriot-reward-ionic/hooks/after_prepare/010_add_platform_class.js /Users/ryanminor/Code/patriot-reward-ionic

add to body class: platform-android

ANDROID_HOME=/Users/ryanminor/Library/Android/sdk

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

Incremental java compilation is an incubating feature.

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.

I believe you need Java 1.8, so I would upgrade that.

rminor · January 30, 2017, 12:05am

I checked that and it says I have Java 8 Update 121. Is there something I need to do with my PATH?

rapropos · January 30, 2017, 12:06am

That “1.7.0” suggests to me that JAVA_HOME is pointing at the wrong JDK.

rminor · January 30, 2017, 12:16am

How do I update it to the new JAVA version? I’ve never had to do this before. Here is my bash_profile:

export PATH=${PATH}:/Users/ryanminor/Library/Android/sdk/platform-tools:/Users/ryanminor/Library/Android/sdk/tools
export PATH=${PATH}:~/.composer/vendor/bin
export JAVA_HOME=$(/usr/libexec/java_home)

When I type echo $JAVA_HOME I get this:
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

rapropos · January 30, 2017, 12:22am

Maybe something useful in here, although you can probably google “osx java 8” as well as I can.

rminor · January 30, 2017, 12:23am

I did. I think installing the Java SE Development Kit should work. I’m doing that now. Thanks for the help.

rminor · January 30, 2017, 12:34am

Installing the Java SE Development Kit fixed my problem and it now builds successfully.
