Since Android Studio 3.0 update, the apk generated will be in
{project-folder}/app/release/app-release.apk
Also 1 more file is generated Output.json which holds the apk generation details.
Sample:
[
{
"outputType":{
"type":"APK"
},
"apkInfo":{
"type":"MAIN",
"splits":[
],
"versionCode":1
},
"path":"app-debug.apk",
"properties":{
"packageId":"njscommunity.xxxxx",
"split":"",
"minSdkVersion":"19"
}
}
]
All depends on Gradle build, so at the end it all depends on Gradle version you build with. i.e. Gradle Android plugin for Android Studio.
