Hello, now let’s take a look at the reasons and solutions for why the application is not installed when installing games on the mobile phone.

Methods/Steps

1

The first idea is that there are program residues in the system. It may not be installed because it has not been deleted, so use the RE browser. Search for program-related keywords, delete all relevant files and directories found, and then restart and install the program again. The result is invalid;

2

I thought of a backup before, so I opened Titanium Backup , find the relevant software, and restore: the first choice is program + data, which shows that the restore failed, and then selects the restore program alone, which prompts that the restore is successful, but there is no successfully restored program in the system, so I was fooled (here I I haven't tried to restart the system. I don't know if it will be effective if I restart the system after restoring. Friends who are interested can try it~);

There is no other way but to Google, the first thing I found is the most successful method: connect to the computer in storage mode or use Root Explorer to find the .android_secure folder in the SD card directory. There should be a smdl2tmp1.asec in it, or it may be another name. In short, it is the same as If the file naming format is obviously different from the normal program, delete it and try to install the software again. However, I cannot find the relevant directories and files in either the system or the SD card, so this method is completely useless to me;

The second method: If the installation of the application on the PC fails, please first check whether the U0SB driver corresponding to the Android phone is installed. Generally, use Haozhuo Mobile Assistant or other mobile assistants. It will automatically install the mobile phone driver for you. I was prompted with a failure on the mobile phone, and my driver was installed correctly and Wandoujia was working normally, so this has nothing to do with me;

The third method: Check whether the phone settings - applications - unknown sources are checked, otherwise some applications not provided by the electronic market will not be installed. I checked it, so this has nothing to do with me;

Fourth method: Use the system's own program management to view the programs on the SD card. Some programs do not have colored icons. It turns out that these software without icons are causing trouble. Software without icons are software data that were not installed correctly or were incompletely uninstalled in the past. If you install it again, an error will be reported. Now we use the system’s own software management to uninstall them cleanly. There will be no errors when installing the software again, but I can’t even see any icons using the system’s built-in program management, so this method is useless to me;

7

The fifth method: just delete /mnt /secure/asec/smdl2tmp1.asec (in driver mode: removable disk/.android_secure/smdl2tmp1.asec), then install it. This method is a supplement to the first method. Unfortunately, my system and card are There is no mnt directory at all, so it is useless;

8

Sixth method: When upgrading an installed program, the prompt "The application is not installed" will appear when upgrading a small number of software. , I can only uninstall the old version and install the new version. I can't find the uninstall at all, so it's useless;

9

The seventh method: in Settings-Development- If you check Allow simulated locations, it's OK. I checked this but it still doesn't work;

10

The eighth method: connect the phone to the computer and open 91 Mobile Assistant, and install it casually For an application, choose the installation path as the phone's memory. I am running a 2.1 system. The software is originally installed in the "memory", so this is useless;

11

The ninth method: There is also a part where the software signature has changed, so the installation cannot be overwritten. Just delete it and reinstall the new version. This principle is the same as method six, so it does not work for me;

12

The tenth method: directly restore factory settings. This is a method I don’t want to do. In theory, it should be effective.

END

Solution

After all the above attempts, the problem still cannot be solved. It’s so frustrating. Do I have to do a factory reset? I hesitate. Thirdly, I have started to prepare for reinstallation, but when I searched for the installation principles of Android system, I actually found a way to solve this non-installation problem that has troubled me for a long time. Let's take a look at the solution together:

In fact, the Android system program installation is to copy the APK file to the APP directory and grant permissions. The backup is also to copy the APK file and related data files. According to this principle, I did the following:

First download the APK installation package of the application and put it into the SD card;

Rename the APK file to the form com.xxx.xxx.apk (compare the file name in the system APP directory)

Put it in the app folder and modify the permissions before installing

Still "the program is not installed"

At this point, all possible methods have been tried, the solution is: Decisive Abandon this software!
