android studio 在release打包时修改AndroidManifest.xml

在androidmanifest.xml 加入打包时间
第一步:androidmanifest.xml 中添加
<meta-data
android:name="releaseTime"
android:value="releaseTime_value">
</meta-data>
第二步：在build.gradle中添加

android.applicationVariants.all{ variant ->                variant.outputs.each { output ->                    output.processManifest.doLast{                        def manifestFile = output.processManifest.manifestOutputFile                        def updatedContent =manifestFile.getText('UTF-8').replaceAll("releaseTime_value","${releaseTime()}")                        manifestFile.write(updatedContent, 'UTF-8')                    }                }            }
