A NullPointerException is thrown in case of an attempt to dereference a null value. The dereference may be a function call, a read or write of a field, or an array access. An ANDROID.NPE error is reported for Android-specific null pointer dereference situations.

@PepijnKramer It's also there in the AOSP code and it's a valid nullptr because it's somewhat of an optional variable which don't need to be used. See android.googlesource.com/platform/frameworks/native/+/refs/tags/… which I also linked to in my question above.

If an attacker can control the program's environment so that "cmd" is not defined, the program throws a NULL pointer exception when it attempts to call the trim() method. String cmd = System.getProperty("cmd"); cmd = cmd.trim(); This Android application has registered to handle a URL when sent an intent:
