关于android编译时出现'Unable to resolve target 'android-5'
我用eclipse最新版的来编译一个android项目,在run as 的时候,出现了错误:'Unable to resolve target 'android-5',我根据网上查找,是这样来解决的:rnrn这种错误一般大部分是SDK 版本不符所造成的,一般会在Ecplise工作空间导入项目时候出现此错误,一般提示:Error:Unable to resolve target android-X(X是一个数字)。rnrn 解决方案:修改工程目录下的default.properties文件里的内容target=android-X改成target=android-N就可以了,X表示针对于当前项目的错误版本号,N表示针对于当前项目的正确版本号。rnrn rnrn问题是,我project里找不到"default.properties"文件,我看到工程里只有“project.properties”,请教一下。如下图是文件夹的目录:rn[img=http://img.my.csdn.net/uploads/201212/25/1356424149_2502.JPG][/img]rnrn

关于studio升级到3.1.3遇到的问题
1,配置'compile'已经过时,已被'implementation'和'api'取代。 将compile替换成api即可,conpile和api等同。 2,Android Gradle插件无法识别SourceSet的“instrumentTest”。 将androidTest替换instrumentTest,编译运行即可。 3,Configuration 'androidTestCom...

android studio 查看源码时有些类显示 can not resolve 的问题
Android studio的build.gradle的dependency的版本号后面的‘+’加号
如题,加号+的意思是保证依赖最新版本号的文件,但是不建议使用+,最好使用确定的版本的依赖。 如果我不知道一个依赖包该用什么具体版本,就可以使用加号+,代表使用最新的版本号。 为什么我会用到这个‘+’? 升级Android studio到3.0.1后,在我的公司的电脑需要配置重写repository{  }闭包,就是改变获取依赖的库的地址。 然后报错了,提示不能解析依赖,实际上就是没有找到此
