今天测试一个例子：

有问题！

Server侧：

IMyService.java:

package com.test.frameworkBinder; import android.os.IInterface; import android.os.RemoteException; public interface IMyService extends IInterface { static final java.lang.String DESCRIPTOR = "com.test.frameworkBinder.MyServer"; public void sayHello(String str) throws RemoteException; static final int TRANSACTION_say = android.os.IBinder.FIRST_CALL_TRANSACTION; } MyService.java:

package com.test.frameworkBinder; import android.os.Binder; import android.os.IBinder; import android.os.Parcel; import android.os.RemoteException; public class MyService extends Binder implements IMyService { public MyService() { this.attachInterface(this, DESCRIPTOR); } @Override public IBinder asBinder() { return this; } // convert MyService to IMyService Interface public static com.test.frameworkBinder.IMyService asInterface( android.os.IBinder obj) { if ((obj == null)) { return null; } android.os.IInterface iInterface = obj.queryLocalInterface(DESCRIPTOR); if (((iInterface != null) && (iInterface instanceof com.test.frameworkBinder.IMyService))){ return ((com.test.frameworkBinder.IMyService) iInterface); } return null; } // Server side: receive remote message, and deal with OnTransact() @Override protected boolean onTransact(int code, Parcel data, Parcel reply, int flags) throws RemoteException { switch (code) { case INTERFACE_TRANSACTION: reply.writeString(DESCRIPTOR); return true; case TRANSACTION_say: data.enforceInterface(DESCRIPTOR); String str = data.readString(); sayHello(str); reply.writeNoException(); return true; } return super.onTransact(code, data, reply, flags); } // Server side's sayHello() @Override public void sayHello(String str) { System.out.println("MyService:: Hello, " + str); } } ServerDemo.java:

package com.test.frameworkBinder; import android.os.Looper; import android.os.ServiceManager; public class ServerDemo { public static void main (String[] args) { System.out.println("MyService start"); Looper.prepareMainLooper(); android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_FOREGROUND); ServiceManager.addService("MyService", new MyService()); Looper.loop(); } }

Client 侧：

IMyservice.java:

package com.test.frameworkBinder; import android.os.IInterface; import android.os.RemoteException; public interface IMyService extends IInterface { static final java.lang.String DESCRIPTOR = "com.test.frameworkBinder.MyServer"; public void sayHello(String str) throws RemoteException; static final int TRANSACTION_say = android.os.IBinder.FIRST_CALL_TRANSACTION; } MyServiceProxy.java:

package com.test.frameworkBinder; import android.os.IBinder; import android.os.RemoteException; public class MyServiceProxy implements IMyService { private android.os.IBinder mRemote; public MyServiceProxy(android.os.IBinder remote) { mRemote = remote; } public java.lang.String getInterfaceDescriptor() { return DESCRIPTOR; } @Override public void sayHello(String str) throws RemoteException { android.os.Parcel _data = android.os.Parcel.obtain(); android.os.Parcel _reply = android.os.Parcel.obtain(); try { _data.writeInterfaceToken(DESCRIPTOR); _data.writeString(str); mRemote.transact(TRANSACTION_say, _data, _reply, 0); _reply.readException(); } finally { _reply.recycle(); _data.recycle(); } } @Override public IBinder asBinder() { return mRemote; } }

ClientDemo.java:

package com.test.frameworkBinder; import android.os.IBinder; import android.os.RemoteException; import android.os.ServiceManager; public class ClientDemo { public static void main(String[] args) throws RemoteException { System.out.println ("Client start"); IBinder binder = ServiceManager.getService("MyService"); IMyService myService = new MyServiceProxy(binder); myService.sayHello("Binder"); System.out.println("Client end"); } }

编译完成后：

adb push ServerDemo /system/bin adb push ClientDemo /system/bin adb push ServerDemo.jar /system/framework adb push ClientDemo.jar /system/framework

运行：

窗口1：

adb shell root@:/ # /system/bin/ServerDemo Aborted (core dumped) 窗口2：

C:\>adb shell root@:/ # /system/bin/ClientDemo Aborted (core dumped)

看来要调试下。
