+# Generating C++ Binder Interfaces with `aidl-cpp`
+
+## Background
+
+“aidl” refers to several related but distinct concepts:
+
+ - the AIDL interface [definition language](http://developer.android.com/guide/components/aidl.html)
+ - .aidl files (which contain AIDL)
+ - the aidl generator which transforms AIDL into client/server IPC interfaces
+
+The _aidl generator_ is a command line tool that generates client and server
+stubs for Binder interfaces from a specification in a file with the .aidl
+extension.  For Java interfaces, the executable is called `aidl` while for C++
+the binary is called `aidl-cpp`.  In this document, we’ll use AIDL to describe
+the language of .aidl files and _aidl generator_ to refer to the code generation
+tool that takes an .aidl file, parses the AIDL, and outputs code.
+
+Previously, the _aidl generator_ only generated Java interface/stub/proxy
+objects.  C++ Binder interfaces were handcrafted with various degrees of
+compatibility with the Java equivalents.  The Brillo project added support for
+generating C++ with the _aidl generator_.  This generated C++ is cross-language
+compatible (e.g. Java clients are tested to interoperate with native services).
+
+## Overview
+
+This document describes how C++ generation works with attention to:
+
+ - build interface
+ - cross-language type mapping
+ - implementing a generated interface
+ - C++ parcelables
+ - cross-language error reporting
+ - cross-language null reference handling
+
+## Detailed Design
+
+### Build Interface
+
+Write AIDL in .aidl files and add them to `LOCAL_SRC_FILES` in your Android.mk.
+If your build target is a binary (e.g. you include `$(BUILD_SHARED_LIBRARY)`),
+then the generated code will be C++, not Java.
+
+AIDL definitions should be hosted from the same repository as the
+implementation.  Any system that needs the definition will also need the
+implementation (for both parcelables and interface).  If there are multiple
+implementations (i.e. one in Java and one in C++), keep the definition with the
+native implementation.  Android
+[now has systems](https://developers.google.com/brillo/?hl=en) that run the
+native components of the system without the Java.
+
+If you use an import statement in your AIDL, even from the same package, you
+need to add a path to `LOCAL_AIDL_INCLUDES`.  This path should be relative to
+the root of the Android tree.  For instance, a file IFoo.aidl defining
+com.example.IFoo might sit in a folder hierarchy
+something/something-else/com/example/IFoo.aidl.  Then we would write:
+
+```
+LOCAL_AIDL_INCLUDES := something/something-else
+```
+
+Generated C++ ends up in nested namespaces corresponding to the interface’s
+package.  The generated header also corresponds to the interface package.  So
+com.example.IFoo becomes ::com::example::IFoo in header “com/example/IFoo.h”.
+
+Similar to how Java works, the suffix of the path to a .aidl file must match
+the package.  So if IFoo.aidl declares itself to be in package com.example, the
+folder structure (as given to `LOCAL_SRC_FILES`) must look like:
+`some/prefix/com/example/IFoo.aidl`.
+
+To generate code from .aidl files from another build target (e.g. another
+binary or java), just add a relative path to the .aidl files to
+`LOCAL_SRC_FILES`.  Remember that importing AIDL works the same, even for code
+in other directory hierarchies: add the include root path relative to the
+checkout root to `LOCAL_AIDL_INCLUDES`.
+
+### Type Mapping
+
+The following table summarizes the equivalent C++ types for common Java types
+and whether those types may be used as in/out/inout parameters in AIDL
+interfaces.
+
+| Java Type             | C++ Type            | inout | Notes                                                 |

+| long                  | int64\_t            | in    |                                                       |

+| String                | String16            | in    | Supports null references.                             |
+| @utf8InCpp String     | std::string         | in    | @utf8InCpp causes UTF16 to UTF8 conversion in C++.    |
+| android.os.Parcelable | android::Parcelable | inout |                                                       |
+| T extends IBinder     | sp<T>               | in    |                                                       |
+| Arrays (T[])          | vector<T>           | inout | May contain only primitives, Strings and parcelables. |
+| List<String>          | vector<String16>    | inout |                                                       |
+| PersistableBundle     | PersistableBundle   | inout | binder/PersistableBundle.h                            |
+| List<IBinder>         | vector<sp<IBinder>> | inout |                                                       |
+| FileDescriptor        | unique_fd           | inout | android-base/unique_fd.h from libbase                 |
+
+Note that annotations may be placed at the interface level, as well as on a
+type by type basis.  Interface level annotations will be applied
+opportunistically and be overridden by per type annotations.  For instance, an
+interface marked @nullable will still not allow null int parameters.
+
+### Implementing a generated interface
+
+Given an interface declaration like:
+
+```
+package foo;
+
+import bar.IAnotherInterface;
+
+interface IFoo {
+  IAnotherInterface DoSomething(int count, out List<String> output);
+}
+```
+
+`aidl-cpp` will generate a C++ interface:
+
+```
+namespace foo {
+
+// Some headers have been omitted for clarity.
+#include <android/String16.h>
+#include <cstdint>
+#include <vector>
+#include <bar/IAnotherInterface.h>
+
+// Some class members have been omitted for clarity.
+class IFoo : public android::IInterface {
+ public:
+  virtual android::binder::Status DoSomething(
+      int32_t count,
+      std::vector<android::String16>* output,
+      android::sp<bar::IAnotherInterface>* returned_value) = 0;
+};
+```
+
+Note that `aidl-cpp` will import headers for types used in the interface.  For
+imported types (e.g. parcelables and interfaces), it will import a header
+corresponding to the package/class name of the import.  For instance,
+`import bar.IAnotherInterface` causes aidl-cpp to generate
+`#include <bar/IAnotherInterface.h>`.
+
+When writing a service that implements this interface, write:
+
+```
+#include "foo/BnFoo.h"
+
+namespace unrelated_namespace {
+
+class MyFoo : public foo::BnFoo {
+ public:
+  android::binder::Status DoSomething(
+      int32_t count,
+      std::vector<android::String16>* output,
+      android::sp<bar::IAnotherInterface>* returned_value) override {
+    for (int32_t i = 0; i < count; ++i) {
+      output->push_back(String16("..."));
+    }
+    *returned_value = new InstanceOfAnotherInterface;
+    return Status::ok();
+  }
+};  // class MyFoo
+
+}  // namespace unrelated_namespace
+```
+
+Note that the output values, `output` and `returned_value` are passed by
+pointer, and that this pointer is always valid.
+
+#### Dependencies
+
+The generated C++ code will use symbols from libbinder as well as libutils.
+AIDL files using the FileDescriptor type will also explicitly require
+libnativehelper, although this is likely a transitive dependency of the other
+two, and should be included automatically within the Android build tree
+regardless.
+
+### C++ Parcelables
+
+In Java, a parcelable should extend android.os.Parcelable and provide a static
+final CREATOR field that acts as a factory for new instances/arrays of
+instances of the parcelable.  In addition, in order to be used as an out
+parameter, a parcelable class must define a readFromParcel method.
+
+In C++, parcelables must implement android::Parcelable from binder/Parcelable.h
+in libbinder.  Parcelables must define a constructor that takes no arguments.
+In order to be used in arrays, a parcelable must implement a copy or move
+constructor (called implicitly in vector).
+
+The C++ generator needs to know what header defines the C++ parcelable.  It
+learns this from the `cpp_header` directive shown below.  The generator takes
+this string and uses it as the literal include statement in generated code.
+The idea here is that you generate your code once, link it into a library along
+with parcelable implementations, and export appropriate header paths.  This
+header include must make sense in the context of the Android.mk that compiles
+this generated code.
+
+```
+// ExampleParcelable.aidl
+package com.example.android;
+
+// Native types must be aliased at their declaration in the appropriate .aidl
+// file.  This allows multiple interfaces to use a parcelable and its C++
+// equivalent without duplicating the mapping between the C++ and Java types.
+// Generator will assume bar/foo.h declares class
+// com::example::android::ExampleParcelable
+parcelable ExampleParcelable cpp_header "bar/foo.h";
+```
+
+### Null Reference Handling
+
+The aidl generator for both C++ and Java languages has been expanded to
+understand nullable annotations.
+
+Given an interface definition like:
+
+```
+interface IExample {
+  void ReadStrings(String neverNull, in @nullable String maybeNull);
+};
+```
+
+the generated C++ header code looks like:
+
+```
+class IExample {
+  android::binder::Status ReadStrings(
+      const android::String16& in_neverNull,
+      const std::unique_ptr<android::String16>& in_maybeNull);
+};
+```
+
+Note that by default, the generated C++ passes a const reference to the value
+of a parameter and rejects null references with a NullPointerException sent
+back the caller.  Parameters marked with @nullable are passed by pointer,
+allowing native services to explicitly control whether they allow method
+overloading via null parameters.  Java stubs and proxies currently do nothing
+with the @nullable annotation.
+
+Consider an AIDL type `in @nullable List<String> bar`.  This type
+indicates that the remote caller may pass in a list of strings, and that both
+the list and any string in the list may be null.  This type will map to a C++
+type `unique_ptr<vector<unique_ptr<String16>>>* bar`.  In this case:
+
+  - `bar` is never null
+  - `*bar` might be null
+  - `(*bar)->empty()` could be true
+  - `(**bar)[0]` could be null (and so on)
+
+### Exception Reporting
+
+C++ methods generated by the aidl generator return `android::binder::Status`
+objects, rather than `android::status_t`.  This Status object allows generated
+C++ code to send and receive exceptions (an exception type and a String16 error
+message) since we do not use real exceptions in C++.  More background on Status
+objects can be found here.
+
+For legacy support and migration ease, the Status object includes a mechanism
+to report a `android::status_t`.  However, that return code is interpreted by a
+different code path and does not include a helpful String message.
+
+For situations where your native service needs to throw an error code specific
+to the service, use `Status::fromServiceSpecificError()`.  This kind of
+exception comes with a helpful message and an integer error code.  Make your
+error codes consistent across services by using interface constants (see
+below).
