Some mobile phones have downloaded a software program but did not install it during installation. When checking the software management, it shows that the program is not installed. Why is this? How to solve it? Let’s take a look below!

What to do if the application is not installed

#When Android installs an application, it prompts that the program is not installed due to the following reasons: (recommended learning: PHP video tutorial)

  • An application with the same package name is already installed on the phone.

  • The current mobile phone operating system does not meet the system version required by the program package.

  • The phone has insufficient storage space.

  • The installation package has been damaged.

Solution:

  • If "The application is not installed" is displayed, you need to check first. If the "Unknown Sources" option is not checked, applications that are not provided by the electronic market cannot be installed.

  • Because the APP installation fails, a temporary file will appear in the memory card of the phone. You can connect to the computer through the data cable, and then you will see a "mobile phone" removable device on the computer. .

  • Then double-click to open the removable disk, you will enter the page in the picture below, and then you need to find the .android_secure folder in the SD directory, as shown in the picture below, just in the red box Select the location and delete the file named "smdl2tmp1.asec".

  • Finally, you need to turn on the phone again, and then find the security software installed on the phone, and then clean up the garbage. You can also use the phone’s built-in garbage removal program. After the cleaning is completed, Just re-download the APP.

  • Check whether it is installed on this machine. If so, uninstall it directly.

  • Check the version of the program package to see if it is consistent with the current phone.

  • Uninstall some useless or rarely used apps on your phone to free up storage space on your phone.

  • Re-download the installation package.
