With the start-up of Android 5.0 Lollipop and latest update in the various devices, a new Error 505 has started showing up in the Google Play Store. If you are one of the victims, you may have noticed that whenever you try to install any app from the Google Play Store, it says- Unknown error code during Application install: “-505”. To call it just ‘Error code 505‘ for ease, this code is also one of the various errors occurring in the Google Play Store, where the application downloads complete, but the error pops out whenever the device is trying to install the downloaded app.

Error 505As reported, most of the Adobe Air based apps are having the problem on working with the Lollipop and Marshmallow version, especially in the Samsung, OPPO, Nexus 7 2012 model tablet. The popular apps, such as RedTeam, Bingo Blitz, Evernote, Weather App, ITV, Adobe Air 15, SBI, We Chat have their icons missing after being updated to Android 5.0 Lollipop, and show the error 505 code while trying to install them again.

Fixes for error 505

SymptomsThe apps icons will vanish. When you go to the play store, it will show you the ‘install’ option, which suggests the apps are hidden (if not uninstalled) from the device. Any other method, such as using the app uninstaller option also proves the app is not working. After you tap in the ‘install’ option, error 505 occurs.

CauseNothing is known about this yet, but the incompatibility issues are reported to be the major cause for the occurance of Error 505 for the Air-based apps. The app incompatible with the version and thus, hidden seems to be logical.

SolutionAfter you update your Android device to Android 5.0 Lollipop from an older version using Over-the-air update or sideloading factory image, do a factory reset. It has been found out that if you do a factory reset immediately after updating your Android version, the error does not occur, but if you don’t the error persists. Don’t forget to clear the cache too, going to Menu > Settings > Apps > Google Play Store > Clear Cache. Clear the data too, from the very same option.

  • If the error still persists after having the factory reset after update, or in case you haven’t reset your device and using it suffering the updates, you can try a next method. If you are using the Adove Air 15 version, and it is showing the error, try using Adobe Air 14 and create the APK with captive runtime. This will most probably help you solve your problem.
  • If you are familiar with the Android Debug Bridge, use it to uninstall the apps (if they are just hidden and not uninstalled), and afterwards try to install the app again from the Play Store. [Useful for you: How to Install Android Debug Bridge (ADB).]

Though this is the solution for the short term, let’s hope the developers of the apps will figure out the incompatibility issues of the apps soon, and repair it. Also share your thoughts with smartphone and app on comment below.

  1. Booted into CWM, performed a backup to sd, did a factory reset from CWM, cleared cache from CWM, Restored backup and Reboot, Have been in reboot with lollipops whirling for about a hour now, ???

      • It did not work what a mess , lol phone went into a soft brick I quest lollipops whirling no way to stop I tried resets backup restores nothing worked, Finally hat to use root toolbox to flash stock image then after I got it up after boot I did factory reset then let Google restore my last backup that they had , overall with some computer space issues in order to unzip the file for the image I was with out my phone for over 20 hours lol, and guess what I’m right back where I started 505 error still can’t install tasker so I can figure out how it works with utter, so it’s got to be something with the Google image file going around that there pushing, factory reset no go. I did exactly as it said as soon as image was done after first boot did the reset lol almost thought I was going to buy new phone still might. Do you know what its like to use a converted HD2 windows phone to android haha

  2. This is not an incompatibility issue by the app. You make it sound like developers are to blame. This is an Android bug that google needs to fix. Android lollipop is calculating a different sha1 from the certificate than KitKat did and thus not allowing the app to install. Developers cannot change certificates of existing apps so it is out of their hands. The solution is to do an adb uninstall of the app that won’t update but then the app data will not persist.

  3. I Finally got time to try adb and still get duplicate permissions when using install over adb, if I try uninstall the error is just a internal error like it can’t find the file. File attempted adb install tasker.4.5u1.apk

  4. Same problem here for Verizon GS5 running stock. After taking it to the store and getting hokey resolution (buy another battery and ‘just don’t use gps with any of the other radios’ advice) I have been racking my brain to fix. Have nearly all Tasker plugin out there. Apparently the problem has to do with pebble taskwatch and tasker. Try uninstalling taskwatch and then installing Tasker to see if that fixes the issue. Currently under lollipop they both cannot be installed on your device at the same time. I didn’t find out this suggestion until after another solution that worked for me. I did a factory reset. During the restore wizard I chose NOT to install any apps (I didn’t know which ones were causing the 505 error at that point) and only let the restore install basic data. After the restore wizard completed, I could easily go into play store and install tasker with no issues. The only caveats with this solution is that I can’t install Pebble Taskwatch (non-issue since I only really use AutoPebble) and I think I have to manually re-install all the other 658 apps I had on my phone before Verizon and Android screwed me over. Overall impression- Lollipop aint too sweet, but at least I got Tasker back.

  5. So, I found a workaround to get past the -505 error, but it requires a few things: a rooted device, a custom recovery that can install zipped apps, and the app2zip app available on the play store (should be free).

    Here’s what I did:
    1. Install Tasker first.
    2. Run the App2Zip app, and have it back up the app you installed.
    3. Uninstall Tasker, and install Utter.
    4. Repeat the backup procedure using App2Zip.
    5. Boot into your custom recovery, and install both zipped apps.
    6. Boot back into your OS after the installs finish, and you should have both Tasker and Utter installed.

    It is sad that this is still an issue, but hopefully this will help as a workaround until they fix this issue in 5.x

    • Technically you should be able to do this with any offending apps, but you need to know what apps you already have installed that cause the 505 permission error first. If you can find a zipped version of that app online (preinstalled and zipped after) all the better.

    • Thanks very much for this – I had the identical problem, and was going crazy trying to understand what was going on. As an alternative to App2Zip, Titanium Backup also has the ability to convert an app or apps to an update.zip file.

  6. Mystery solved on Error Code 505!!! I discovered from Samsung tech support that the reason I was getting this error when trying to install a mobile banking app was that I already had a similar app installed – even though it was from a different bank. It will allow only one app of that type to be installed on the phone at once. Those apps are competing for the same settings. Also, it is a security measure to prevent viruses from reaching your phone.

    I had to uninstall the app from the first bank before installing the second one. I’ll have to take turns between the two apps installing and uninstalling so that only one is active at a time.

    Hallelujah for the solution (because I really needed to make a deposit immediately). Maybe this applies to other types of apps as well.

    • Hey! Beverly Glover!

      Do you think that this is a permanent solution? What if I need to use both the apps installed simultaneously in the Samsung phone?

    • My Dad just came to me and said that every time i try to re-install Facebook (after uninstalling it due to the fact it wouldn’t update or open the app) it downloads the app the app from the play store and gets so far into installing it and then says ERROR -505 cant install the app any ideas on a way round it ?

  7. What i did was Cleared data and flashed Euphoria rom 5.1 June/02 release, skipped gapps and then downloaded play games from playstore. Then it asked to update google play services and updated that too. Everything is fine now.

    We are such slaves to games that i lost lots of data and time in this whole process 🙁

  8. I got this error too, icon & widget disappears. I simply reapplied the widget, adding it back on homescreen. Icon in applications still doesn’t work and looks different, as if app has been deleted. But if I copy that same icon, to the homepage, it also works, altjought, it’s appearance stays same. The widget is fully operational.
    I’m not ready to try factor reboot.
    I don’t think I need the update that bad, maybe I’ll wait until someone in charge fixes the bug.

  9. I tried uninstall, reinstall, and nothing. The same crap. Error 505 and no icon. But I could play the game and it was updated. Day or so later the icons reappeared on their own. So idk, maybe do nothing and see what happens. Maybe it will correct itself like mine did.

  10. For root user with SuperSU, working solution for error code 505.
    1. Google the apps com. name (eg. com.candycrushsodasaga)
    2. Install “Terminal Emulator” from play store.
    3. Open apps, and enter following command on Terminal Windows:
    su

    (enter, SuperSu promt to “Grant” access)
    4. Enter another 2 command:
    adb shell
    pm uninstall com.candycrushsodasaga

    (This should remove all installation cached from your device. Goto play store and reinstall the apps.)

  11. First of all it’s not client side error, it’s developer’s side error. If a developer has uploaded 2 or more applications with same signature then it is impossible to install even two of them. Best solution for you is to uninstall any other app you have from the same developer and install the installation you were trying before.

    For developers: You need to change your app signature in every application which is different from other. But if you are just publishing an update to, make sure just change the version number not signature.

  12. Still can’t download Google play games because if the error 505. I used the local SKK lollipop version 5.01 aAndroid so I can’t play coc on may phone since I can’t switch may account

  13. NONE OF THE ABOVE: had both MS Word & Messenger working just fine in Lolipop 5.1 untill it says they have to update. Then 505 error, and, Icon disappeared, so It really has nothing to do with resetting or fac update
    I’ve been using Messenger & Word right up until this bad update. Has nothing to do with Lolipop, if it did I wouldn’t have been using Messenger this past year. It’s these constant unnecessary updates by poor coders wanting to change something that’s not broke, that’s the problem. #Dumb

  14. Excuse me I know the perfect cause why this error505 occurs. Let me explain. I have downloaded gangster vegas which is a Gameloft game and later I tried to download six guns then this annoying thing showed up. This is because both the packages have the same name ie., Com.gamloft.GNMP or something else. So to avoid this you need to move one app to sd card so the package also transfers. If the error perror persists again it means there may be junk folder in Android/obb. If you delete it then everything thing will be fine.
    Thanking you

  15. Here it is. I have got the final solution. These developers are using same certificates for all of their apps. so you can not install 2nd app from the same developer if u have an app already installed from the same developer. Just uninstall the previous app and there u go. Now u can install ur desired app, just only one from the same developer.

    • Please how do I go about this? I use a Hauwei y6 pro. I’m trying to download the WPS + PDF app. How do I find out the apps that are from the same developer or have same certificates? Thank you.
