I have questions about delta update:   Is delta updates world wide? What version of Android work with delta updates? Are all apps supported for delta updates? Is there any work to do to activate this feature?   I ask this question because I can't use this feature and still have to download whole size of app for updates

I find it rather strange that for updating an app in Android (or even iOS) the entire app is downloaded instead of only the actual "Updates".  The reason I find this strange is because in Windows while updating an app, only the update files are downloaded -- not the entire app -- which is more practical as it saves both time and data usage.  This would seem trivial to most, but when you need to download a huge app just for a tiny feature addition/bug fix it becomes a real PITA.  Does anyone have an explanation as to why this model was implemented?

I am trying to update from version 2.0.0 to version 2.1.2 in Ubuntu 64bit/14.04LTS but when I click "update and restart" it says "Downloading patches" and it closes.   It does not start again and if I try to open it, the version is still 2.0.0.   Is there any tutorial to manually update android studio? (keep all settings and etc).

Ever since I upgraded to 13.10, the software updater does not show all the available updates. Some will appear and can be installed just fine, but once it claims that all software is up to date, using sudo apt-get upgrade shows that there are still more packages waiting to be updated. I can update them via the command line, but that only solves things temporarily. I'm not sure why some show up and others don't. How can I make Update Manager update all packages?  Update-manager shows this:    But apt-get shows this:   Thanks!

I've been having an issue with my apps where an error "" keeps appearing. I read a tutorial somewhere which told me to "uninstall updates" for the Google Play Store application. I was told doing this would uninstall the application, and then the device would automatically reinstall Google Play Store.  I did this, restarted my phone, but the application never reappeared.  I think tried downloading an .apk file to install this manually, but on install the application wouldn't load.  Has anyone done this before? How can I reinstall this application? I believe I need it for all future downloads and updates to my applications.  For the record, my phone is not rooted.

I have Ubuntu computers and an Android phone, and it's always perplexed me why the default update manager on Ubuntu and Google Play on the phone don't update existing versions of applications by calculating the difference between them and the new versions. I'm sure this is the case with other operating systems as well (which is why this question isn't in Ask Ubuntu or Android enthusiasts)  Consider, for example, the latest update (a minor release) of  (as of April 18,2012). The "What's new" section says it includes a critical bug fix. It's safe to assume a lot of code wasn't modified, and yet, when you update the app, it downloads over 6 MB, as if it's a fresh install.   Why can't the update servers calculate the difference (a la git) with installed versions and send only the difference? Can it really be that hard to do that with all versions? Wouldn't the saved bandwidth be a major motivation?  Edit 6 Dec 2016: Google just announced that they are going to use file-by-file patching for Android APK updates -

In the  of the Android app, it says Android 4.1 or higher is required. However, the  argues that 1.6 is the required Android version. Why do these two pages argue with each other, and which one is lying?  Screen shot:

The alpha channel launch page says there is version 1.0.1.84 to install but actually installs 1.0.1.83 resulting in the app asking to update again.  Can't use alpha app as result.

Does the Android operating system support installing new fonts?  I am that person who adores calligraphy and improving handwriting, and I am proud to say that my handwriting is now more beautiful than my teachers in almost every language I know! Anyway, can anyone answer that question (about Android fonts), because this will judge if I will buy a ruuning-Android tablet pc or not!

As the title says, I'd like to enable auto-update for trusted apps (e.g. Google apps), but if I open the app in Play Store and check Auto-update, I get the question "Auto-update is currently disabled for all apps. Do you want to enable it? You can always change this in Settings. Data charges may apply." Now, if I select Yes, auto-update is turned on for all apps and I have to deselect each one separately.  What I'm looking for is a way to enable auto-update, deselect all apps from auto-update and manually select which apps are allowed to auto-update (i.e. opt-in instead of opt-out).  Running stock 4.2.2 on Sony Xperia Z. I haven't rooted the device so solutions without root are preferred.  EDIT: The situation turned even worse. Now, if I have several apps waiting to be upgraded and I select Update all, I get a popup for each and every app asking "Auto-update has been disabled for [app], are you sure you want to update?". Seems like we're being driven to enable auto-update for all apps, and I don't like it.

The update from Ubuntu 13.10 to 14.04 LTS does not work it keeps showing me an error as could not calculate the upgrade, even when I want it to get updated from the terminal it says the same error. I did not use the beta its the final Ubuntu 14.04 LTS.I have restarted my laptop for like 5-10 times no change. Disabling the software sources also does not help.

I am looking at using  , but I am not sure how easy it is to update a distribution when a new version comes out.  Also, can I use drush to do it, or do I have to manually download and unpack the distribution?

Not a problem, but have been seeing questions recently of people not being offered upgrade from 18.04 to 20.04.  I thought these upgrades were offered back in June.  I upgraded to 20.04 from 19.10 and this was offered back in May.  Imagine that different versions paths have different schedules, but google does not help explaining(that I found).  Does someone know the schedules?

I'm subscribed to the Ubuntu Security Notes, so everytime that I receive an e-mail, a new update is avalable.  But in the last update, they wrote something in the end that I coudn't undertand much, so can anyone please tell me what does that means?  ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.   I tried to ask to my friend (who also uses Linux), but he don't know much about kernel.

Android Market has just updated an app in my device. I liked the update, but its fully different from last version which was also my favorite. So, I want to keep last version too. I have last version's apk thanks to Titanium Backup. But, I can't install it without replacing current one (Android architecture sucks). Is there any way to do this? Hacks etc.. Note: I want to keep current version which must be connected with Market to receive future updates.

I'm wondering why Android apps won't be able to be run natively on . I mean, isn't it all just Linux?

I'm using the official Stack Exchange mobile app for iOS or Android, and  My app crashed! It doesn't look good on my new smartphone. It won't run after I updated my device. I noticed another bug. I have an idea for a new feature which is currently not in the app.  How do I report bugs with or request features for the iOS and Android apps? Also:  I've used the built-in functionality of the app to report a bug or submit a feature request. Did I do the right thing? The app prompted me to post on Meta after an error occurred. Should I post about it here? I'm wondering why the latest version is from 2017. I've heard rumors that the apps are no longer supported; is that true? I can't find the app on my device's app store anymore! Where did it go?     We get a lot of bug reports from users about the mobile apps, which are unsupported, and at the moment, there is no centralized Q&amp;A pair for those to be closed as duplicates of (the relevant answers are spread across multiple unrelated questions). This question is an FAQ proposal, to serve as a directly-related duplicate target for those questions.
