e.g. It is impossible to add server-side errors obfuscation
Some security XSS concerns that are not quite elegantly solvable, see docs (I am not sure whether this is more elegant for RequestFactory)

How do I use a file grep comparison inside a bash if/else statement?
...grep:
Exit status is 0 if any line was selected, 1 otherwise;
if any error occurs and -q was not given, the exit status is 2.

What are the differences between a pointer variable and a reference variable in C++?
...ontain nullptr.
int *p = nullptr;
int &r = nullptr; <--- compiling error

...getApi and @SuppressLint have the same core effect: they suppress the Lint error.
The difference is that with @TargetApi, you declare, via the parameter, what API level you have addressed in your code, so that the error can pop up again if you later modify the method to try referencing something ne...
Volatile vs Static in Java
...les.
Using volatile variables reduces the risk of memory consistency errors, because any write to a volatile variable establishes a happens-before relationship with subsequent reads of that same variable. This means that changes to a volatile variable are always visible to other threads
