Is it safe to use static class variables in an android application
<p>I am aware of the technique of extending the Application class to provide global storage. However in my case I am writing a class for a library function, so do not wish to force users of the class down this path. I have a requirement for some static class variables. I have seen passing references in StackOverflow that these might not be safe. However I've tried two different applications using the same class, and even when running both applications side by side on a Galaxy S3 in multi-window mode, the static class variables remain separate.</p>

<p>So, can someone with an in depth knowledge of Android internals confirm if this is safe or not.</p>

<p>If it is not safe, I can wrap the variables in a nested class and add them to a Serializable static HashMap, using the application package name as the key. This will force them to be safe. However if this is not necessary, then I'd rather not do it. </p>
