error C4839: 作为可变参数函数的参数的非标准用法

by

报错语句为：

1

	_stprintf_s(filepath, _T("%s\\%s"), curpath, CA2T(iniFilePath));

改为如下就不报错了：

1
2

	CString iniFilePathT = CA2T(iniFilePath);
	_stprintf_s(filepath, _T("%s\\%s"), curpath, (LPCTSTR)iniFilePathT);

targetSdkVersion未安装应用程式

发布后在Android 6.1的手机上安装不了，显示“未安装应用程序”，检查源码发现build.gradle文件中

1
2
3
4

    defaultConfig {
        minSdkVersion 14
	targetSdkVersion 27
    }

于是，把targetSdkVersion改为23，而发布release版时，Signature Versions只选V1(Jar Signature)。
再将生成的apk包在安卓6.1手机上装，顺利安装成功。
