How to determine if my app is running on Android [duplicate]

Question

I have an app that runs on several mobile devices running either Fedora or Android. To consolidate my codebase and distribution I would like to determine which OS I am on. I tried System.getProperty("os.name"), but that just returns "Linux". Is there something unique to Android in the System properties? Thanks

Answer 1

There are several properties you could check. Candidates are:

• java.vendor.url --> http://www.android.com
• java.vm.name --> Dalvik (I don't know, which one Fedora is using...)
• java.vm.vendor --> The Android Project
• java.vendor --> The Android Project

Maybe you want to check by yourself?

Properties p = System.getProperties(); Enumeration keys = p.keys(); while(keys.hasMoreElements()) {    String key = (String) keys.nextElement();    String value = (String) p.get(key);    System.out.println(key + " >>>> " + value); }

I do not know Android but if you do not find some unique system property you can sometimes identify the system if some specific class exists there. So you can do the following:

boolean isAndroid() {     try {         Class.forName("the class name");         return true;     } catch(ClassNotFoundException e) {         return false;     } }
