Go to https://play.google.com/apps/publish/ and login in to your developer account.

Click on the app that you want the information and go to `Statistics` on the left menu.

Now, you have a graph on your page. You can select the type of stats you want to see on the top in the middle, keep &quot;Installs on active devices&quot; selected. Right below that, you have another dropdown on &quot;Android version&quot;. You&#39;ll want to click that and find one of which says `App Version`. Click there and the second graph will update and show different color for each released version of your app.

[![Screenshot of the play console][1]][1]

You can see on the top of the graph the different versions (19, 21, 22). You can hover your mouse on the lines to see the quantity for each app version. There&#39;s also the default &quot;All app versions&quot;.

The date interval can also be changed on the top to see farther in the past.

Updated screenshot for new play console, since this answer keeps getting attention :)

The play console has changed, now you need to go to &quot;Statistics&quot; in the left menu, then click on &quot;configure report&quot;, choose &quot;app version&quot; in the right column. Then you have the statistics by app version in the last section of the page.

This is how it&#39;s done on the Google Play Console as of January 2021.

In `Statistics`, use the 2 dropdown menus below `Configure report` to select:
- `Users &gt; Installed audience`
- `View by: App version`

Unfortunately, there is a significant delay which prevents getting meaningful data during the first DAYS following a new release...

Surprisingly, Firebase Analytics &quot;Latest Release&quot; dashboard has an even worse delay in its `% of active users` data!

I had a problem with catching the exception from `Task.Run` which was resolved by changing the code as follows. I&#39;d like to know the difference between handling exceptions in these two ways :

In the `Outside` method I can&#39;t catch the exception, but in the `Inside` method I can.

    void Outside()
    {
        try
        {
            Task.Run(() =&gt;
            {
                int z = 0;
                int x = 1 / z;
            });
        }
        catch (Exception exception)
        {
            MessageBox.Show(&quot;Outside : &quot; + exception.Message);
        }
    }

    void Inside()
    {
        Task.Run(() =&gt;
        {
            try
            {
                int z = 0;
                int x = 1 / z;
            }
            catch (Exception exception)
            {
                MessageBox.Show(&quot;Inside : &quot;+exception.Message);
            }
        });
    }

Longer time I&#39;m curious about HTML tag `&lt;marquee&gt;`.

You can find in [MDN specification][1]:

&gt;  **Obsolete**
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

or on [W3C wiki][2]:

&gt; No, really. don&#39;t use it.

I searched several articles and found some mention about CSS relevant replacement. CSS attributes like:

    marquee-play-count
    marquee-direction
    marquee-speed

but it seems, they don&#39;t work. They were a part of specification in year [2008][3], but they were excluded in year [2014][4]

One way, proposed by W3 Consortium, is using [CSS3 animations][5], but it seems for me much more complicated than easy-to-maintain `&lt;marquee&gt;`.

There are also plenty of [JS alternatives][6], with lots of source code that you can add to your projects and make them larger.

I&#39;m always reading things as: &quot;don&#39;t ever use marquee&quot;, &quot;is obsolete&quot;. And I don&#39;t get why.

So, can anybody explain to me, **why** is marquee deprecated, why is so &quot;dangerous&quot; using it and **what is the easiest substitution**?

I found an [example][7], it looks nice. When you use all prefixes needed for good browser support, you have around 20-25 lines of CSS, with 2 values hardcoded (start and stop indent), depending on text length. This solution is not so flexible, and you can&#39;t create bottom-to-top effect with this.

I have recently pushed a new version of an Android App to the play store, and would like to see how many of our users have managed to get the update already. 

There seems to be stats for days on the android version and the devices that are being used, but I cant seem to find anything on what version of the app my users are using.

I want to add some child Views (List Items), which come to me from JSON formatted data. Each child list is under a parent list item row. How can I populate it in `RecyclerView` for each row item (Parent items with child list items)?

I have tried using `RecyclerView` within `RecyclerView` parent row (for populating child lists), but here child views are not visible.

How to have a ListView/RecyclerView inside a parent RecyclerView?

I just started using Android Studio 1.3 sdk 24 and it has worked fine until today. I get this error message about cache.properties and I delete that cache file but now I am getting this error message:          

   &gt;Error:C:\Users\user1\.gradle\caches\2.4\scripts\asLocalRepo15_dhjxrnvsgiyg1ow3dfj4myl7\InitScript\initscript\cache.properties (The system cannot find the file specified)       

I try file/invalidate caches/restart.. and rebuild project but am still getting this error message. How do I fix it?

When I attempt to navigate to the Android developer website, I am redirected to a version of it much of which is in Chinese. For instance, if I try to navigate to:

    developer.android.com

I am redirected to:

    http://developer.android.com/intl/zh-cn/index.html

I want the English language site. In some cases, I&#39;ve had to have web pages translated from Chinese. What am I doing wrong? How can I suppress this behavior?

How do I set the language for the Android developer website?

I&#39;m trying to add a night theme for my app and I&#39;ve wasted nearly three hours just trying to make the text and icons in my navigation drawer turn white along with the dark background. Here is the way I&#39;m trying to go about doing this in `onCreate()` in `MainActivity.java`:

    navigationView = (NavigationView) findViewById(R.id.navigation_view);
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

        // This method will trigger onItemClick of navigation menu
        @Override
        public boolean onNavigationItemSelected(MenuItem menuItem) {

            // Checking if the item is in checked state or not, if not make it in checked state
            if (menuItem.isChecked())
                menuItem.setChecked(false);
            else menuItem.setChecked(true);

            if (nightMode == 0) {
                SpannableString spanString = new SpannableString(menuItem.getTitle().toString());
                spanString.setSpan(new ForegroundColorSpan(Color.WHITE), 0, spanString.length(), 0); // fix the color to white
                menuItem.setTitle(spanString);
            }

The `nightMode` boolean is irrelevant because it works. When night mode is set to on (0), whatever menu item is selected in the navigation drawer turns white. However, that only happens when each item is selected which is obviously inconvenient. Here is my drawer_dark.xml:

        &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    &lt;menu xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;&gt;
        &lt;group
            android:checkableBehavior=&quot;single&quot;&gt;
            &lt;item
                android:id=&quot;@+id/unitone&quot;
                android:checked=&quot;true&quot;
                android:icon=&quot;@drawable/one_white&quot;
                android:title=&quot;Classical Period&quot; /&gt;
            &lt;item
                android:id=&quot;@+id/unittwo&quot;
                android:checked=&quot;false&quot;
                android:icon=&quot;@drawable/two_white&quot;
                android:title=&quot;Postclassical Period&quot; /&gt;
            &lt;item
                android:id=&quot;@+id/unitthree&quot;
                android:checked=&quot;false&quot;
                android:icon=&quot;@drawable/three_white&quot;
                android:title=&quot;Early Modern Era&quot; /&gt;
            &lt;item
                android:id=&quot;@+id/unitfour&quot;
                android:checked=&quot;false&quot;
                android:icon=&quot;@drawable/four_white&quot;
                android:title=&quot;Dawn of Industrial Age&quot; /&gt;
            &lt;item
                android:id=&quot;@+id/unitfive&quot;
                android:checked=&quot;false&quot;
                android:icon=&quot;@drawable/five_white&quot;
                android:title=&quot;Modern Era&quot; /&gt;
        &lt;/group&gt;
    &lt;/menu&gt;

I&#39;m using white icons on a transparent background for each item, yet they show up as black on the black background of the navigation drawer. I&#39;ve tried looking for an xml solution to changing the color of the text and I&#39;m scratching my head because I don&#39;t know why this was overlooked.

Can someone offer me a dynamic solution in getting what I&#39;m trying to achieve? All help is appreciated, thank you!

It completely ignores:

So I got exception:

&gt; Caused by: android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@86fb55b -- permission denied for this window type

It&#39;s not even listed:

&lt;b&gt;EDIT:&lt;/b&gt;

It&#39;s listed in Configure apps/ Advanced / Draw over other app. So i turn it on and now it works fine, but why there isn&#39;t any dialog to ask about permission when i run my app? All perrmissions was turned off by deafult and i need to go to settings and mannualy turn it on?

Permission from manifest doesn&#39;t work in Android 6

I have an app published to the alpha channel, with an in-app (un)managed item that costs $1.

When I purchase normally, i.e, use a credit/debit card Google returns the correct developer payload string, but if I choose to &quot;redeem&quot; a promo code and enter said code, Google returns an empty developer payload string, and thus authentication fails in &#39;onIabPurchaseFinished()&#39;.

I should mention that this only occurs if I choose to redeem a code from the app&#39;s purchase flow, and everything works flawlessly if I open Play Store first, redeem the code, and then come back and open the app.

Is this a bug on  Google&#39;s part?

EDIT: The Play Store thing is expected, since it can&#39;t know your payload and the purchase is done without having to check for it.

In-app purchases made via promo codes return empty developer payload string

I have gone through many questions like this on Google Play, I am using **Android 4.2.2 API 17**. 

My app requires Google play services 8.1 , It compiles fine and when it runs on emulator it shows message that **&#39;You need to update your Google play services &#39;** , 

When I click on update nothing happens, 

**How can I update the Google Play services  without downloading any latest API version ?**


updating Google play services in Emulator

I have a link which will open in webview. The problem is it cannot be open until I override onReceivedSslError like this:

     @Override
            public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
                handler.proceed();
            }

I am getting security alert from google play saying:

&gt; Security alert
Your application has an unsafe implementation of the WebViewClient.onReceivedSslError handler. Specifically, the implementation ignores all SSL certificate validation errors, making your app vulnerable to man-in-the-middle attacks. An attacker could change the affected WebView&#39;s content, read transmitted data (such as login credentials), and execute code inside the app using JavaScript.
&gt;
To properly handle SSL certificate validation, change your code to invoke SslErrorHandler.proceed() whenever the certificate presented by the server meets your expectations, and invoke SslErrorHandler.cancel() otherwise.

After googling quite a bit I am unable to find the answer to this question. Is google play store officially support in avd emulators. 

I know it was once stopped , then I hear that it was brought back after specific version of android. I am using avd android version 4.4.3 (api 19) google app . I dont see a google play store app there. Am I suppose to expect it? Or is there an official apk for google play store that can be installed on the avd officially?

&#39;Start rollout to beta&#39; disabled in Play Store Developer Console

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?

Google Play: Can&#39;t RELEASE TO PRODUCTION because &quot;a draft release in production already&quot;, what to do?

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)?
