 *                                 Android AIDL自动生成Java文件测试

 * 说明：

 *     知道有aidl这东西已经挺久了，但是一直没有花时间来系统了解一下其工作机制，现在

 * 花点时间一点一点验证一下其功能。

二、cat forService.aidl

    package com.example.aidltest.aidl;

    import com.example.aidltest.aidl.forActivity;

    interface forService {

        void registerTestCall(forActivity cb);

        void invokCallBack();

    }

三、cat forService.java

    /*

     * This file is auto-generated.  DO NOT MODIFY.

     * Original file: D:\\soft\\Android\\workspace\\AidlTest\\src\\com\\example\\aidltest\\aidl\\forService.aidl

     */

    package com.example.aidltest.aidl;

    // 继承了android.os.IInterface接口

    public interface forService extends android.os.IInterface {

        /** Local-side IPC implementation stub class. */

        // Stub类继承了Binder，并继承我们在aidl文件中定义的接口

        public static abstract class Stub extends android.os.Binder implements

                com.example.aidltest.aidl.forService {

            private static final java.lang.String DESCRIPTOR = "com.example.aidltest.aidl.forService";

            /** Construct the stub at attach it to the interface. */

            public Stub() {

                this.attachInterface(this, DESCRIPTOR);

            }

            /**

             * Cast an IBinder object into an com.example.aidltest.aidl.forService

             * interface, generating a proxy if needed.

             */

            // 在使用的时候经常会看到这一部分的内容

            public static com.example.aidltest.aidl.forService asInterface(

                    android.os.IBinder obj) {

                if ((obj == null)) {

                    return null;

                }

                android.os.IInterface iin = obj.queryLocalInterface(DESCRIPTOR);

                if (((iin != null) && (iin instanceof com.example.aidltest.aidl.forService))) {

                    return ((com.example.aidltest.aidl.forService) iin);

                }

                return new com.example.aidltest.aidl.forService.Stub.Proxy(obj);

            }

            @Override

            public android.os.IBinder asBinder() {

                return this;

            }

            @Override

            public boolean onTransact(int code, android.os.Parcel data,

                    android.os.Parcel reply, int flags)

                    throws android.os.RemoteException {

                switch (code) {

                case INTERFACE_TRANSACTION: {

                    reply.writeString(DESCRIPTOR);

                    return true;

                }

                case TRANSACTION_registerTestCall: {

                    data.enforceInterface(DESCRIPTOR);

                    com.example.aidltest.aidl.forActivity _arg0;

                    _arg0 = com.example.aidltest.aidl.forActivity.Stub

                            .asInterface(data.readStrongBinder());

                    this.registerTestCall(_arg0);

                    reply.writeNoException();

                    return true;

                }

                case TRANSACTION_invokCallBack: {

                    data.enforceInterface(DESCRIPTOR);

                    this.invokCallBack();

                    reply.writeNoException();

                    return true;

                }

                }

                return super.onTransact(code, data, reply, flags);

            }

            private static class Proxy implements

                    com.example.aidltest.aidl.forService {

                private android.os.IBinder mRemote;

                Proxy(android.os.IBinder remote) {

                    mRemote = remote;

                }

                @Override

                public android.os.IBinder asBinder() {

                    return mRemote;

                }

                public java.lang.String getInterfaceDescriptor() {

                    return DESCRIPTOR;

                }

                @Override

                public void registerTestCall(

                        com.example.aidltest.aidl.forActivity cb)

                        throws android.os.RemoteException {

                    android.os.Parcel _data = android.os.Parcel.obtain();

                    android.os.Parcel _reply = android.os.Parcel.obtain();

                    try {

                        _data.writeInterfaceToken(DESCRIPTOR);

                        _data.writeStrongBinder((((cb != null)) ? (cb.asBinder())

                                : (null)));

                        mRemote.transact(Stub.TRANSACTION_registerTestCall, _data,

                                _reply, );

                        _reply.readException();

                    } finally {

                        _reply.recycle();

                        _data.recycle();

                    }

                }

                @Override

                public void invokCallBack() throws android.os.RemoteException {

                    android.os.Parcel _data = android.os.Parcel.obtain();

                    android.os.Parcel _reply = android.os.Parcel.obtain();

                    try {

                        _data.writeInterfaceToken(DESCRIPTOR);

                        mRemote.transact(Stub.TRANSACTION_invokCallBack, _data,

                                _reply, );

                        _reply.readException();

                    } finally {

                        _reply.recycle();

                        _data.recycle();

                    }

                }

            }

            static final int TRANSACTION_registerTestCall = (android.os.IBinder.FIRST_CALL_TRANSACTION + );

            static final int TRANSACTION_invokCallBack = (android.os.IBinder.FIRST_CALL_TRANSACTION + );

        }

        // AIDL中自定义的方法，没有实现

        public void registerTestCall(com.example.aidltest.aidl.forActivity cb)

                throws android.os.RemoteException;

        public void invokCallBack() throws android.os.RemoteException;

    }

四、cat MainActivity.java

    public class MainActivity extends ActionBarActivity {

        @Override

        protected void onCreate(Bundle savedInstanceState) {

        ......

        new forService.Stub() {

                @Override

                public void registerTestCall(forActivity cb) throws RemoteException {

                    // TODO Auto-generated method stub

                }

                @Override

                public void invokCallBack() throws RemoteException {

                    // TODO Auto-generated method stub

                }

            };

        ......

        }

    }
