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：

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">allprojects {gradle<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.projectsEvaluated</span> {tasks<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.withType</span>(JavaCompile) {options<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.compilerArgs</span> << <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"-Xlint:unchecked"</span> << <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"-Xlint:deprecation"</span>}}

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
