At some point you probably hit &quot;Create release&quot; while you were in the Production Management page then left the draft there. Go and Edit that draft and click &quot;Discard&quot; on it then you&#39;ll be able to move an app from Beta to Prod

Java 9 has three ways to package compiled code in files:

 - JAR
 - JMOD
 - JIMAGE 

JIMAGE is optimized for speed and space and used by the JVM at runtime so it makes sense why JIMAGE was introduced. JIMAGE files are not supposed to be published to maven repos or used at compile or link time. 

The docs claim that JMOD can store native code and other things that can&#39;t be stored by JAR files and that developers can make and distribute their own JMOD files. The JDK ships with `jmods/` directory containing all the modules of the JDK for users to depend on. 

**Questions:** 

 - Why did Java 9 introduce the JMOD file format?
 - Should a library author distribute a JMOD file or a JAR file or both? 
 - Should jmod files be published to maven repos?

I am trying to release a new version of my app at Google Play Console.

I have one version which I didn&#39;t release and then I uploaded a new one to Beta that I want to release.

When I press on the &quot;RELEASE TO PRODUCTION&quot; button I get the following message:

&gt; &quot;To release to production, ensure that you don&#39;t have a draft release
&gt; in production already&quot;

If I try to &quot;RELEASE TO PRODUCTION&quot; the former version I get the same message. How can I break this loop? any ideas?

Upload new APK to Alpha - failed

I am trying to get familiar with Kotlin to use in my android apps. So first I want to try out some simple kotlin examples, just to get familiar with syntax of kotlin.

I made a class named `Main.kt` in my android project with just main method.

    fun main(args: Array&lt;String&gt;) {
    println(&quot;Hello World&quot;); }

Android studio shows me a kotlin icon to left of main method and when I click on this icon, It shows me below three option:

1) Run Mainkt

2) Debug Mainkt

3) Run Mainkt with coverage

I chose first one but it throws me 

    Exception in thread &quot;main&quot; java.lang.ClassNotFoundException: com.vikalp.kotlin.MainKt
	at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

	at java.lang.Class.forName(Class.java:264)
	at com.intellij.rt.execution.application.AppMainV2.main(AppMainV2.java:107)



I am stuck with such a small problem. Let me know if anyone of you have faced problem like this and what is the solution.

How to access values from strings.xml

I&#39;m getting the following **runtime error**:

     checkParameterIsNotNull, parameter oneClickTokens
        at com.info.app.fragments.Fragment_Payment_Profile$fetchMerchantHashes$1.onPostExecute(Fragment_Payment_Profile.kt:0)
        at com.info.app.fragments.Fragment_Payment_Profile$fetchMerchantHashes$1.onPostExecute(Fragment_Payment_Profile.kt:1543)


Here&#39;s **my code**:

     private fun fetchMerchantHashes(intent: Intent) {
        // now make the api call.
        val postParams = &quot;merchant_key=$key&amp;user_credentials=$var1&quot;
        val baseActivityIntent = intent
        object : AsyncTask&lt;Void, Void, HashMap&lt;String, String&gt;&gt;() {
    
            override fun doInBackground(vararg params: Void): HashMap&lt;String, String&gt;? {
                    ...
            }
    
            override fun onPostExecute(oneClickTokens: HashMap&lt;String, String&gt;) {

                ...
    
            }
        }.execute()
    }


It seems that the function call seems to be invalid. However, I don&#39;t know how to fix this problem. Is there anything Kotlin specific I&#39;ve missed?

Is there a way to remove an APK from the library in the Google Play Developer Console?

To make sure: I don&#39;t mean to revert to an earlier version or unpublish an app, but to remove it from the list that can be seen after clicking on &quot;ADD APK FROM LIBRARY&quot; in Release Management&gt;App Release.

The version that I want to remove has not been used in any release.


Remove APK from library in Google Play Developer Console

I&#39;m trying to release an app to the Google Play store. I&#39;ve gone through all the required steps in the Google Play Console (play.google.com/apps/publish)

But when I click App Releases on the left, then click Edit Release under Production, add an APK then click Review on the bottom, it takes me to the &quot;Confirm rollout to production: 1.0&quot; page, with the familiar START ROLLOUT TO PRODUCTION button on the bottom. That button is greyed out so I can&#39;t click it. The Review Summary at the top of the page says &quot;This release is ready to be rolled out.&quot;

What am I doing wrong?

&#39;Start Rollout to Production&#39; button disabled

i&#39;m desperate. I published the wrong update for an app on the play store by the new Play Developer Console. 

No i need to rollback my update, simply REMOVING it and re-publish the previous. 

I cannot understand 2 things: 

- how remove it from the apps versions menu
- re-publish the previous one


Please help me! 
Thanks in advance 

Google Play Console - How remove an update of published application

I am working to publish a private, internal release for our app in the Google Play Store. I&#39;m getting a message saying &quot;An opt-in link will be available here when you publish your app&quot;, but I don&#39;t know what else I need to do publish my alpha test apk. 

The release status says &quot;full rollout&quot;, which indicates to me that everything is done.

I know it takes hours for it to appear but I already waited for days. What do I need to do to get this URL? If I sideload the apk that I created, will it be the same as downloading from the store (in terms of IAP authorisation)?

Android Releases in the Google Play Store: Where is the Opt-in URL?

When a crash occurs in an application installed via the Google Play app, user&#39;s have the option to Send Feedback.

[![Send Feedback][1]][1]

A user can optional write feedback to describe the problem they have encountered and then submit their crash report.

 1. Is the written feedback provided by the user available anywhere in the Google Play Console?
 2. Can the feedback be associated with a stack trace of the crash the user encountered?
