Answer 1

Things you have to keep in mind when updating your application on Google Play :

1. Change Version code +1 depending on the old value - if it's 1 , you have to change it to a bigger number.

2. Change your App Version Name to something bigger / different if it's string - if your old version is 1.0 - it should be 1.1 / 1.0.1 or whatever you like (it's always a better option t have some version name strategy, if it will contains the date update affffded or the revision it depends on you).

And if you want to be able to update your app, don't change project package name! That's how android system knows that this application is different than that one. If you change your package name, it's now acting like a new app and you won't be able to update it from Google Play Store! To change your package name to com.corntail.project first you need to change it in manifest and after that in your project's main package and you need to keep track of your activities, if you declared them with package name too. For example :

if your MainActiivty was declared in manifest like :

com.corntail.main.MainActivity 

you need to change it now to be like :

com.corntail.project.MainActivity.

Answer 2

If you build with gradlew, you should check the build.gradle file, the applicationId will overwrite the package value in the AndroidManifest.xml

android {
    defaultConfig {
        applicationId "xxx.xxx.xxx"
    }
}

Answer 3

You need to use a different version code for your APK because you already have one with version code 1.

You must change your version code in your androidmanifest.xml

Answer 4

You need to change your android:versionCode="1" to 2 on the AndroidManifest...

Answer 5

You have change version code in increasing order i.e. 1,2,3...so on as every time you uploaded. In every upload version code should have greater number than previous upload version code. You can change version code in APP Module Build.gradle file.

Image

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.2"
    defaultConfig {
        applicationId "com.xyz"
        minSdkVersion 14
        targetSdkVersion 24
        versionCode 5
        versionName "1.1.4"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

Answer 6

If you're using Android Studio or building with gradle, edit your gradle script (build.gradle) to change your package name and version. These values overwrite your AndroidManifest.xml file.

For example:

 defaultConfig {
        applicationId "com.xyz.abc"
        minSdkVersion 16
        targetSdkVersion 19
        versionCode 2
        versionName "1.1"
    }
