AndroidStudio打包出现问题: `Error:Execution failed for task ':app:lintVitalRelease'.

1，错误代码： 
`Error:Execution failed for task ‘:app:lintVitalRelease’.

Lint found fatal errors while assembling a release target. 
To proceed, either fix the issues identified by lint, or modify your build script as follows: 
… 
android { 
lintOptions { 
checkReleaseBuilds false 
// Or, if you prefer, you can continue to check for errors in release builds, 
// but continue the build even when errors are found: 
abortOnError false 
} 
}`

解决方法： 
在app的build.gradle里的android{}中添加如下代码,然后再次运行Generate Signed Apk。例如：

android{
    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }
}
