我正在尝试为我的第一个Android应用程序创建圆形按钮.
为此,我compile 'com.cuboid:cuboidcirclebutton:1.0.5'在circlebutton/app/build.gradle中添加了库
当我同步时,我收到错误.下面是日志

假设我想将整个代码放在注释中,以便我可以在代码中测试其他内容
/* This is my first comment */
printf("\n This is my first print command");
/* This is my second comment */
printf("\n This is my second print command");
如果我做
/*
/* This is my first comment */
printf("\n This is my first print command");
/* This is my second comment */
printf("\n This is my second print command");
*/
这是在创造错误.
编译器正在考虑这两个.
