Reason for Unknown Error code message


Before going to the solution, please understand why this error massage displayed on your device.  Simply saying the main reason of this issue is because of the presence of same folder name on your device memory.

How to solve “Unknown error code during application install ” issue?


1. Doing a factory reset


This is an well proven and self tried method of solving this issue. As I said earlier, I faced problem when installing Clash of Clans. Then I tried a factory reset. I will not recommend this method for anyone those having important files and data on Phone memory. Performing Factory reset and Wiping Cache will erase all wanted and unwanted files without any backup. In my case, I am using my tablet for entertainment purpose and done without looking future activities. After rebooting, I installed the same app from market and I got a positive result. As I self tested and have experience I recommend this as the best solution.


2. Deleting the corresponding files and folders [Only for rooted device]


If you are afraid of doing a factory reset, try this method. Before that, keep in mind that this would work if you have a rooted mobile or tablet. As I mentioned earlier the reason for this error is the multiple arriving of same data files and folders. In this solution you can solve this issue by deleting the older or duplicate files and folders. On your File explorer you could able to view all the data files of installed applications.

  • Go to File Explorer
  • Find the folder and files having the same name of the corresponding app.

"Unknown error code during application install

  • The folder may named like .com.appname. eg: .com.clashofclans.
  • Long tap on the Folder



  • From the list of options choose delete option. This will delete the folder and files. Note that this will possible only if you had a rooted device.

In both the solutions you are doing the same concept. Delete the related files and folders.


Another solutions found on Android forums


I had viewed many other suggestions made by android users on several forums. I don’t know whether this work or not. Try this for fun and if you success it would be great.

One of the user commented that he faced this issue while downloading this app via Wi-Fi connection. After he download the same app through mobile data network, it worked fine and installed without any errors.

Another commented that he changed the static ROM to Custom ROM. I know that this will work because changing ROM requires a Factory Reset. So I requesting readers that there is no need of changing ROM for solving this issue.
