as3.0以上在gradle.properties使用android.enableAapt2=true，as就会提示将要过期了，请设置成
android.enableAapt2=false。当我设置成false啦，这时候编译出错误。

Multiple substitutions specified in non-positional format; did you mean to add the formatted="false"

就是当你的string.xml上含有要格式的字符串比如

<string name="time_picker">%s时</string>

这时候会提示上述错误，因为sdk采用了更加严格的aapt编译，正确的用法如下

If you need to format your strings using String.format(String, Object...) , then you can do so by putting your format arguments in the string resource. For example, with the following resource:


In this example, the format string has two arguments: %1$s is a string and %2$d is a decimal number. You can format the string with arguements from your application like this:


 <string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>

解决方法：

之前我们用的%s 改为%1$s,如果在一个字符串有两个%s,%s。现在要改为%1$s，%2$s，重新编译没ok了。

拓展

如果字符串含有%，而不需要格式化可以有三种方法解决

1. 加上formatted="false"

<string name="time_picker" formatted="false">%s时</string>

1. 用两个%%

<string name="time_picker">%%s时</string>

2. 用转义字符\

<string name="time_picker" >\%s时</string>
