What's the scope of System.setProperty in Android?
If I set a property (say System.setProperty("http.keepAlive", "false")), does it affect all apps in the system, the current app, the current task or the current thread only?
Where is this documented?

Java™ system properties determine the environment in which a Java program runs by starting a Java virtual machine with a set of values. You can choose to use the default values for Java system properties or you can specify values for them by adding parameters to the command line when you start your application.
Scope of the System properties (Beware that running the two programs above will make them go into an infinite loop!) It turns out, when running the two programs using two separate java processes, the value for the property set in one JVM process does not affect the value of the other JVM process.
System properties include information about the current user, the current version of the Java runtime, and the character used to separate components of a file path name.
setProperty manages the initialization of the Chrome driver in the first step. The System. setProperty() method forms the basis for test case automation on any browser. Naturally, QAs must understand how to use this fundamental method for all automation purposes in Selenium.
Java "system" properties do not cross process boundaries, they are held in memory and are tied to a single instance of the virtual machine. Therefore if you set a system property within application it will not be visible to other applications running on the device.
