I doubt this question can be answered conclusively, as it’s a matter of opinion. Or at least I believe so — an opinion too. 🙂 I understand you want “0 warnings” (a very laudable goal) but there’s probably not a “one size fits all” issue. That said… Things I believe you should not do: Use … Read more
The difference is static typing of the expressions at compile time: Summary E1: `(false ? 1.0f : null)` – arg 2 ‘1.0f’ : type float, – arg 3 ‘null’ : type null – therefore operator ?: : type Float (see explanation below) – therefore autobox arg2 – therefore autobox arg3 E2: `(false ? 1.0f : … Read more
The severe method is only used to log severe messages without associated throwable information. If you need to log throwable information then you should use the log method instead: try { data = new GameData.Builder().enemy(enemy).build(); log.fine(“new data object\t\t” + data.getEnemy()); setChanged(); notifyObservers(data); } catch (NullPointerException npe) { log.log(Level.SEVERE, npe.getMessage(), npe); }
I deleted the home/.android folder and everything is normal now.

When the EditText isn’t focused anymore, getCurrentFocus() may return null (unless some other view is focused). void hideKeyboard() { InputMethodManager inputManager = … Read more

Through a combination of @Contract annotations and the External Annotations feature, you can now annotate Preconditions methods such that IntelliJ applies the correct static analysis to calls to these methods. Let’s say we have this example public void doSomething(Object someArg) { Preconditions.checkArgument(someArg != null); someArg.doSomethingElse(); //currently gives NPE warning if (someArg != null) { //no … Read more
I have discovered the root cause for this behavior. You can choose in what way IntelliJ evaluation will display the data: the result can be the Object or toString evaluation. Therefore the error i had experienced, View as->toString was used, while not all the objects had toString implemented. Hope it will help someone in the … Read more
