deprecated

问题 This method was deprecated in API level 19 Database paths are managed by the implementation and calling this method will have no effect. I use setDatabasePath to set the database path of the webview. String databasePath = this.getApplicationContext().getDir("database", Context.MODE_PRIVATE).getPath(); settings.setDatabasePath(databasePath); Does this mean in API 19 it cant find my database anymore?? How to solve this? ( What do they mean with: Database paths are managed by the implementation

问题 Since PHP's call_user_method() and call_user_method_array() are marked deprecated I'm wondering what alternative is recommended? One way would be to use call_user_func(), because by giving an array with an object and a method name as the first argument does the same like the deprecated functions.

The other way I can think of is using the Reflection API, which might be the most comfortable

问题 Starting with 2.10, -Xlint complains about classes defined inside of package objects. But why? Defining a class inside a package object should be exactly equivalent to defining the classes inside of a separate package with the same name, except a lot more convenient. In my opinion, one of the serious design flaws in Scala is the inability to put anything other than a class-like entity (e.g. variable declarations, function definitions) at top level of a file. Instead, you're forced to put them

问题 Let's say I define a custom annotation called @Unsafe . I'd like to provide an annotation processor which will detect references to methods annotated with @Unsafe and print a warning. For example, given this code ... public class Foo { @Unsafe public void doSomething() { ... } } public class Bar { public static void main(String[] args) { new Foo().doSomething(); } } ...
