android – SecurityException：使用应用内结算将Binder调用到错误的界面

我在尝试使用Google提供的应用内结算库时遇到了SecurityException.以下是完整的例外情况：

07-05 15:56:47.783  26481-26481/com.andrewq.planets E/AndroidRuntime﹕ FATAL EXCEPTION: main
    Process: com.andrewq.planets,PID: 26481

这是带有第227行的IabHelper.java方法：

@Override
    public void onServiceConnected(ComponentName name,IBinder service) {
        if (mDisposed) return;
        logDebug("Billing service connected.");
        mService = IInAppBillingService.Stub.asInterface(service);
        String packageName = mContext.getPackageName();
        try {
            logDebug("Checking for in-app billing 3 support.");

            // check for in-app billing v3 support
            //**LINE 227**
            int response = mService.isBillingSupported(3,packageName,ITEM_TYPE_INAPP);
            if (response != BILLING_RESPONSE_RESULT_OK) {
                if (listener != null) listener.onIabSetupFinished(new IabResult(response,"Error checking for billing v3 support."));

                // if in-app purchases aren't supported,neither are subscriptions.
                mSubscriptionsSupported = false;
                return; 
            }
            logDebug("In-app billing version 3 supported for " + packageName);

            // check for v3 subscriptions support
            response = mService.isBillingSupported(3,ITEM_TYPE_SUBS);
            if (response == BILLING_RESPONSE_RESULT_OK) {
                logDebug("Subscriptions AVAILABLE.");
                mSubscriptionsSupported = true;
            } else {
                logDebug("Subscriptions NOT AVAILABLE. Response: " + response);
            }

            mSetupDone = true;
        } catch (RemoteException e) {
            if (listener != null) {
                listener.onIabSetupFinished(new IabResult(IABHELPER_REMOTE_EXCEPTION,"RemoteException while setting up in-app billing."));
            }
            e.printStackTrace();
            return;
        }

        if (listener != null) {
            listener.onIabSetupFinished(new IabResult(BILLING_RESPONSE_RESULT_OK,"Setup successful."));
        }
    }
};

最后,这是IInAppBillingService.java文件,其中第208行是：

@Override public int isBillingSupported(int apiVersion,java.lang.String packageName,java.lang.String type) throws android.os.RemoteException
{
    android.os.Parcel _data = android.os.Parcel.obtain();
    android.os.Parcel _reply = android.os.Parcel.obtain();
    int _result;
    try {
        _data.writeInterfaceToken(DESCRIPTOR);
        _data.writeInt(apiVersion);
        _data.writeString(packageName);
        _data.writeString(type);
        mRemote.transact(Stub.TRANSACTION_isBillingSupported,_data,_reply,0);
        //**LINE 208**
        _reply.readException();
        _result = _reply.readInt();
    }
    finally {
        _reply.recycle();
        _data.recycle();
    }
    return _result;
}

现在,当我第一次启动我的应用程序时会发生将调试器附加到进程后,我得到了异常.

解决方法

找到我的答案( here),希望它能解决你的问题. (它是中文的,但Chrome翻译了它.) 它与客户端的.AIDL位置有关.它必须与服务器中的.AIDL文件完全相同.它必须放在客户端的src文件夹中的同名包中.
