I am trying to emulate an app on my device with cordova in OpenSuse Leap 42.1.
But when I tried to emulate the app with the cordova run I get the error below:
cordova run
Running command: /home/soufraz/Projects/apps/myproject/platforms/android/cordova/run
ERROR: Error: Failed to run "java -version", make sure that you have a JDK installed.
You can get it from: http://www.oracle.com/technetwork/java/javase/downloads.
Your JAVA_HOME is invalid: /usr/lib64/jvm/java-1.8.0-openjdk-1.8.0
ERROR running one or more of the platforms: Error: /home/soufraz/Projects/apps/myproject/platforms/android/cordova/run: Command failed with exit code 2
You may not have the required environment or OS to run this project
I have the java installed and the paths set in ~/.profile.
Which is the configuration error in my environment?
Below my .profile:
JAVA_HOME=/usr/lib64/jvm/java-1.8.0-openjdk-1.8.0
export JAVA_HOME
ANDROID_HOME=/home/soufraz/Install/android-sdk-linux
export ANDROID_HOME
PATH=$PATH:$ANDROID_HOME:$JAVA_HOME
Info about java version:
java -version
openjdk version "1.8.0_60"
OpenJDK Runtime Environment (build 1.8.0_60-b27)
OpenJDK 64-Bit Server VM (build 25.60-b23, mixed mode)

Cordova needs a JDK not a JRE, since it is checking for javac. See check_reqs.js line 86. From your comments you are saying that "Inside this path, there isn't the bin folder" in a JDK you should have a bin directory!
In my specific case, I remove and reinstall all java packages and add one (for 'instinct'):
I removed:java-1_8_0-openjdkjava-1_8_0-openjdk-headlessjava-1_8_0-openjdk-plugin
And added:java-1_8_0-openjdkjava-1_8_0-openjdk-headlessjava-1_8_0-openjdk-pluginjava-1_8_0-openjdk-devel <<-- luckily I hit it
The bin inside main folder appears. With javac and another things.
Thank you guys!
Your path should be like this
PATH=$PATH:$ANDROID_HOME/bin:$JAVA_HOME/bin
and than
export PATH
It's a bit of misunderstanding with java-X_X_X-openjdk packages. Especially when you are used to default Oracle notation.
The JDK part is confusing, because OpenJDK is a project of an open-source implementation of the Java Platform and not a JDK - package actually allowing you to develop in Java. (more precise info here: http://openjdk.java.net/install/index.html)
TLDR:
java-X_X_X-openjdk is Oracle's JRE equivalent.
java-X_X_X-openjdk-devel is Oracle's JDK equivalent.
Verifying java & JDK installations resolved my problem.. Install java & JDK and try..
To build and run apps, you need to install SDKs for each platform you wish to target. Alternatively, if you are using browser for development you can use browser platform which does not require any platform SDKs.
To check if you satisfy requirements for building the platform:
$ cordova requirements
Requirements check results for android:
Java JDK: installed .
Android SDK: installed
Android target: installed android-19,android-21,android-22,android-23,Google Inc.:Google APIs:19,Google Inc.:Google APIs (x86 System Image):19,Google Inc.:Google APIs:23
Gradle: installed
Requirements check results for ios:
Apple OS X: not installed
Cordova tooling for iOS requires Apple OS X
Error: Some of requirements check failed
