在android开发中会遇到各种SDK的接入，很是麻烦。最初在想能不能把所有的SDK都 融合到一个当中，发现有点异想天开。但是也可以解决SDK资源不小心没有引入，导致程序调用接口崩溃问题。经过查资料，还是写了一个小Demo，仅供参 考！很早之前写的了，估计移动基地SDK，有变动，不过道理是一样的。
仅以移动基地SDK举例。
1.移动支付需要的SO文件导入
public class CarrotApplication extends Application { //是否含有移动支付SDK boolean useCMBilling = false; @Override public void onCreate() { // TODO Auto-generated method stub try { Class.forName("cn.cmgame.billing.api.GameInterface"); useCMBilling = true; } catch (ClassNotFoundException ignored) { } if(useCMBilling){ System.loadLibrary("megjb"); } } }
2.初始化移动基地支付
protected void init_cmcc(String app_name, String app_company, String telphone_number) { try { Object [] cmcc_init_obj = {CarrotPaySDK.mContext,app_name,app_company,telphone_number}; Class<?> [] classparam = {Activity.class,String.class,String.class,String.class}; cfcaim.invokeStaticMethod("cn.cmgame.billing.api.GameInterface","initializeApp",cmcc_init_obj,classparam); } catch (Exception e) { // TODO: handle exception Log.e("init_cmcc异常捕捉", "异常："+e.toString()); } }
3.上面 invokeStaticMethod 的实现
/** * 执行某个类的静态方法 * @param className 类名 * @param methodName 方法名 * @param oArray 方法参数 * @param paramTypeArray 构造参数类型 * @author liudb * */ public Object invokeStaticMethod(String className, String methodName, Object[] oArray,Class<?> [] paramTypeArray) throws Exception { Class<?> ownerClass = Class.forName(className); Method method = ownerClass.getMethod(methodName, paramTypeArray); return method.invoke(ownerClass, oArray); }
4.调用支付接口
/** * 执行移动支付 * @param isUsesim sim卡是否可用 * @param isRepeat 计费点是否可重复 * @param index 计费点编号 * @param order 订单号 * @param callback 支付回调 */ protected void cmcc_pay(boolean isUsesim,boolean isRepeat,String index,String order,final CarrotPayCallBack callback){ try { //这里的 callback 是自定义的回调函数，会在步骤7里介绍 cmcc_PayendHandler = new CarrotHandler(CarrotPaySDK.mContext){ @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub super.handleMessage(msg); //这里处理返回结果 callback.onPayEnd(msg.what); } }; // 传入参数 Object [] cmcc_pay_param = {CarrotPaySDK.mContext,isUsesim,isRepeat,index,order,new Object()}; // 参数对应的TYPE Class<?> [] cmcc_pay_paramtyp = {Context.class,boolean.class,boolean.class,String.class,String.class,Object.class}; // "IPayCallback" 是移动支付的回调函数名 cfcaim.invokeContainsInterfaceStaticMethod("cn.cmgame.billing.api.GameInterface", "doBilling", cmcc_pay_param,cmcc_pay_paramtyp,"IPayCallback",CarrotPaySdkFinal.CMCC_PAY); } catch (Exception e) { // TODO: handle exception Log.e("cmcc_pay异常捕捉", "异常："+e.toString()); } }
5.重点就是上面 invokeContainsInterfaceStaticMethod 方法的实现
/** * 执行包含接口的静态方法 * @param className 类名 * @param methodName 方法名 * @param oArray 具体参数 * @param paramTypeArray 构造参数类型 * @param interfaceName 接口名 * @author liudb * */ public Object invokeContainsInterfaceStaticMethod(String className, String methodName, Object[] oArray,Class<?> [] paramTypeArray,String interfaceName,CarrotPaySdkFinal payType) throws Exception { Class<?> ownerClass = Class.forName(className); Class<?>[] argsClass = new Class[oArray.length]; Method [] ms = ownerClass.getDeclaredMethods(); for (int i = 0, j = oArray.length; i < j; i++) { argsClass[i] = oArray[i].getClass(); } Method method = findMethod(ms, methodName, paramTypeArray, interfaceName); Class<?> clazz = Class.forName(othre_callBack.getName()); //因为接口的最后一个参数是回调函数，所以要设置监测回调 oArray[oArray.length -1] = Proxy.newProxyInstance( clazz.getClassLoader(), new Class[]{clazz}, new CarrotPayCallbackMethodInterceptor(payType)); othre_callBack = null; return method.invoke(ownerClass, oArray); }
6.还有如何捕获回调的接口返回的参数 CarrotPayCallbackMethodInterceptor 类的实现
public class CarrotPayCallbackMethodInterceptor implements InvocationHandler { CarrotPaySdkFinal csf; public CarrotPayCallbackMethodInterceptor (CarrotPaySdkFinal paytype){ csf = paytype; } @Override public Object invoke(Object proxy, Method method, Object[] args) throws Throwable { // TODO Auto-generated method stub switch (csf) { case CMCC_PAY: //在这里获得回调函数返回的参数，通过自定义carrotSdkHelper发送给callback处理返回结果 for(int j = 0; j < args.length;j++){ if(args[j].getClass().getName().equalsIgnoreCase("java.lang.Integer")){ Integer result = (Integer)args[j]; switch (result) { case 1: Message msg_cmcc_success = new Message(); msg_cmcc_success.what = CarrotPaySDK.CARROT_PAY_SUCCESS; CarrotPaySDK.carrotSdkHleper.cmcc_PayendHandler.sendMessage(msg_cmcc_success); break; case 2: Message msg_cmcc_faild = new Message(); msg_cmcc_faild.what = CarrotPaySDK.CARROT_PAY_FAILD; CarrotPaySDK.carrotSdkHleper.cmcc_PayendHandler.sendMessage(msg_cmcc_faild); break; default: Message msg_cmcc_faild2 = new Message(); msg_cmcc_faild2.what = CarrotPaySDK.CARROT_PAY_FAILD; CarrotPaySDK.carrotSdkHleper.cmcc_PayendHandler.sendMessage(msg_cmcc_faild2); break; } } } break; case OTHER_PAY: Log.e("___________OTHER_______________", "____________________"+method.getName()); for(int j = 0; j < args.length;j++){ Log.e("___________OTHER_______________"+args[j].getClass().getName(), "____________________"+args[j].toString()); } Log.e("___________OTHER_______________", "______333333______________"); break; default: break; } return null; } }
7.（1）callback 类的介绍
public interface CarrotPayCallBack { public void onPayEnd(int isSuccess); }
（2）具体实现新建一个CarrotPayCallBack，传到4步骤的方法里
new CarrotPayCallBack() { @Override public void onPayEnd(int isSuccess) { // TODO Auto-generated method stub switch (isSuccess) { case CarrotPaySDK.CARROT_PAY_SUCCESS: Toast.makeText(getApplicationContext(), "支付成功", Toast.LENGTH_SHORT).show(); break; case CarrotPaySDK.CARROT_PAY_CANCEL: Toast.makeText(getApplicationContext(), "支付取消", Toast.LENGTH_SHORT).show(); break; case CarrotPaySDK.CARROT_PAY_FAILD: Toast.makeText(getApplicationContext(), "支付失败", Toast.LENGTH_SHORT).show(); break; case CarrotPaySDK.CARROT_PAY_UNKNOW: Toast.makeText(getApplicationContext(), "未知错误", Toast.LENGTH_SHORT).show(); break; default: break; } } }
