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;
}
}
}
