在androidmanifest.xml 加入打包時間
第一步:androidmanifest.xml 中新增
<meta-data
android:name="releaseTime"
android:value="releaseTime_value">
</meta-data>
第二步：在build.gradle中新增

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')
                    }
                }

            }
