在android開發中會遇到各種SDK的接入，很是麻煩。最初在想能不能把所有的SDK都融合到一個當中，發現有點異想天開。但是也可以解決SDK資源不小心沒有引入，導致程式呼叫介面崩潰問題。經過查資料，還是寫了一個小Demo，僅供參考！很早之前寫的了，估計移動基地SDK，有變動，不過道理是一樣的。

        僅以移動基地SDK舉例。

1.移動支付需要的SO檔案匯入。

public class CarrotApplication extends Application {
	//是否含有移動支付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");
		}
	}
}
 

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異常捕捉", "異常："+e.toString());
		}
	}
 

3.上面 invokeStaticMethod 的實現

/**
	 * 執行某個類的靜態方法
	 * @param	className		類名
	 * @param	methodName		方法名
	 * @param	oArray			方法引數
	 * @param	paramTypeArray		構造引數型別
	 * @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);
	}
 

/**
	 * 執行移動支付
	 * @param		isUsesim		sim卡是否可用
	 * @param		isRepeat		計費點是否可重複
	 * @param		index			計費點編號
	 * @param		order			訂單號
	 * @param 		callback		支付回撥
	 */
	protected void cmcc_pay(boolean isUsesim,boolean isRepeat,String index,String order,final CarrotPayCallBack callback){
		try {
			//這裡的 callback  是自定義的回撥函式，會在步驟7裡介紹
                        cmcc_PayendHandler = new CarrotHandler(CarrotPaySDK.mContext){
				@Override
				public void handleMessage(Message msg) {
					// TODO Auto-generated method stub
					super.handleMessage(msg);
                                        //這裡處理返回結果
                                        callback.onPayEnd(msg.what);
				}
			};
			// 傳入引數
			Object [] cmcc_pay_param = {CarrotPaySDK.mContext,isUsesim,isRepeat,index,order,new Object()};
			// 引數對應的TYPE
			Class<?> [] cmcc_pay_paramtyp = {Context.class,boolean.class,boolean.class,String.class,String.class,Object.class};
			// "IPayCallback" 是移動支付的回撥函式名
			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異常捕捉", "異常："+e.toString());
		}
	}

5.重點就是上面 invokeContainsInterfaceStaticMethod 方法的實現

/**
	 * 執行包含介面的靜態方法
	 * @param	className		類名
	 * @param	methodName		方法名
	 * @param	oArray			具體引數
	 * @param	paramTypeArray		構造引數型別
	 * @param	interfaceName	介面名
	 * @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());
		//因為介面的最後一個引數是回撥函式，所以要設定監測回撥
		oArray[oArray.length -1] = Proxy.newProxyInstance(
	            clazz.getClassLoader(),
	            new Class[]{clazz},
	            new CarrotPayCallbackMethodInterceptor(payType));
		othre_callBack = null;
		return method.invoke(ownerClass, oArray);
	}

6.還有如何捕獲回撥的介面返回的引數 CarrotPayCallbackMethodInterceptor 類的實現

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:
                //在這裡獲得回撥函式返回的引數，通過自定義carrotSdkHelper傳送給callback處理返回結果
                          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;  
	}

}

public interface CarrotPayCallBack {  
	    public void onPayEnd(int isSuccess);  
	} 

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(), "支付失敗", Toast.LENGTH_SHORT).show();
						break;
					case CarrotPaySDK.CARROT_PAY_UNKNOW:
						Toast.makeText(getApplicationContext(), "未知錯誤", Toast.LENGTH_SHORT).show();
						break;
					default:
						break;
					}
				}
			}
