android studio 打包release出现的错误

今天给项目打包apk，出现以下错误：

Error:Execution failed for task 'xxx'.
> 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
    }
}

解决方案：

在app的build.gradle中添加如下代码，重新Generate Signed APK

android{
    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }
}
