Before this CL, calling overloaded methods on reverse bound Java
classes and interfaces involved confusing and ugly name mangling.
If a set of methods with the same name differed only in argument count,
the mangling was simply adding the argument count to the name:
func F()
func F1(int32)
But if two or more methods had the same number of arguments, the type
had to be appended:
func (...) F() int32
func (...) F1(int32) (int32, error)
func (...) F__I(int32, int32)
func (...) F__JLjava_util_concurrent_TimeUnit_2(int64, concurrent.TimeUnit)
This CL sacrifices a bit of type safety and performance to regain the
convenience and simplicity of Go by resolving overloaded method dispatch
at runtime.
Overloaded Java methods are combined to one Go method that, when invoked,
determines the correct Java method variant at runtime.
The signature of the Go method is compatible with every Java method with
that name. For the example above, the single Go method becomes the most
general
func (...) F(...interface{}) (interface{}, error)
The method is variadic to cover function with a varying number of
arguments, and it returns interface{} to cover int32, int64 and no
argument. Finally, it returns an error to cover the variant that returns
an error. The generator tries to be specific; for example
func G1(int32) int32
func G2(int32, int32) int32
becomes
func G(int32, ...int32) int32
Overriding Java methods in Go is changed to use the Go parameter types to
determine to correct Java method. To avoid name clashes when overriding
multiple overloaded methods, trailing underscores in the method name are
ignored when matching Java methods. See the Get methods of GoFuture in
bind/testpkg/javapkg for an example.

Before this CL, the type of the implicit "this" parameter to Java methods
implemented in Go could only be a super class of the generated Java
class. For example, the following GoRunnable type is an implementation of
the Java interface java.lang.Runnable with a toString method:
package somepkg
import "Java/java/lang"
type GoRunnable struct {
lang.Runnable
}
func (r *GoRunnable) ToString(this lang.Runnable) string {
...
}
The "this" parameter is implicit in the sense that the reverse generator
automatically fills it with a reference to the Java instance of
GoRunnable.
Note that "this" has the type Java/java/lang.Runnable, not
Java/go/somepkg.GoRunnable, which renders it impossible to call Java
methods and functions that expect GoRunnable. The most practical example
of this is the Android databinding libraries.
This CL changes the implicit this parameter to always match the exact
type. In the example, the toString implementation becomes:
import gopkg "Java/go/somepkg"
func (r *GoRunnable) ToString(this gopkg.GoRunnable) string {
...
}
One strategy would be to simply treat the generated Java classes
(GoRunnable in our example) as any other Java class and import it
through javap. However, since the Java classes are generated after
importing, this present a chicken-and-egg problem.
Instead, use the newly added support for structs with embedded prefixed types
and synthesize class descriptors for every exported Go struct type.

Since generated names now have their package names prefixed, the
extra prefix, "Go", is both confusing and counter-productive to
making the generated ObjC code look like any other native code.
Change the default to the empty prefix, while preserving support
for an explicit prefix if needed.
This is a backwards incompatible change; to keep the old behaviour,
specify "-prefix Go" to the gobind or gomobile command.

Before this CL, generated Java classes or interfaces were inner
classes to the top package class. That is both unnecessary and creates
ugly class names. Instead, move every generated class and interface to its
own package level class.
NOTE: This is a backwards incompatible change and requires every client
of gomobile APIs to be updated to leave out the package class in the
type names. For example, the Go type
package pkg
type S struct {
}
now generates (with the default java package name go) a Java class named
go.pkg.S. The name before this CL was go.pkg.Pkg.S.
Also, change the custom java package to specify the package prefix and
not the full package as before. This is an unfortunate change needed
to avoid name clashes between two bound packages. On the plus side,
the change brings the custom package case closer to the default behaviour,
which is a commen prefix, "go.", and a distinct java package for every
Go package bound.

All OpenGL functions are now methods on a Context interface. The

For mobile apps, the context is owned by an app.App. For now, it is
provided through the events channel on a lifecycle event. Long-term,
it should probably be available by a method on app.App, but this is
inherently racey with our current use of a channel to deliver events.
Shiny-based programs will have a gl.Context associated with a each
shiny.Window. The expectation is each Window will have different
contexts, allowing them to draw separately.

More than a name change, the painting model changes so that the app, not
the library, is responsible for driving painting. If the app is
animating and wants paint events at 60 Hz, it has to ask for that. If
the app is not animating and doesn't need to update its screen, it
shouldn't get any paint events.
Plenty of TODOs, and this CL doesn't get us to a perfect place, but it
is a checkpoint along the way.
The darwin_*.go code changes were minimal. I don't even have a Mac or

sending paint.Events unconditionally are important TODOs. That's the
whole point of switching to this model. I'll leave the actual
implementation to you (crawshaw).
Out of all the example apps, the change to example/network/main.go is

It seems like there ought to be some way to reduce the copy/paste
