注: 某些输入文件使用或覆盖了已过时的 API。 android studio

参考：http://blog.csdn.net/u012416928/article/details/47356887

使用android studio打包应用程序出现如下错误：

注: 某些输入文件使用或覆盖了已过时的 API。 

注: 有关详细信息, 请使用 -Xlint:deprecation 重新编译。 

注: 某些输入文件使用了未经检查或不安全的操作。 

注: 有关详细信息, 请使用 -Xlint:unchecked 重新编译。

编译完之后就告诉我这寥寥无几的错误提示，让我情何以堪，于是google了下得到的答案：

我把这段代码粘贴过来了：

}
}

重新编译得到如下错误提示：

好吧，果然错误提示变的非常详细，接下来就可以去修改这些警告了，如果你有时间的话

在项目build.gradle中添加：显示出详细错误位置



allprojects { gradle.projectsEvaluated { tasks.withType(JavaCompile) { options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation" } }}
