I thought I had a backup before, so I opened the titanium backup, found the relevant software, and resumed: at first, I chose program+data to show that the recovery failed, and then I chose the recovery program alone to show that the recovery was successful, but I didn't see a successful program in the system, so I was fooled (I didn't try to restart the system here, and I don't know if it is effective to restart the system after recovery, so interested friends can try it ~);

There is no choice but Google. The most successful method is to connect the computer or find it in storage mode. Android_secure folder under SD card directory with Root Explorer. There should be *** dl2tmp 1.asec in it, and there may be other names. In short, I deleted the file whose naming format is obviously different from the normal program and tried to reinstall the software, but I couldn't find it in the system or the SD card.

The second method: If installing the application prompt on the PC fails, please check whether the U0SB driver corresponding to the Android phone is installed first. Generally, using Haozhuo mobile assistant or other mobile assistants will automatically install the mobile phone driver for you. My mobile phone prompt failed, my driver was installed correctly, and pea pods was working normally, so this has nothing to do with me.

The third method: check whether the mobile phone settings-applications-unknown sources have been checked, otherwise some applications provided by non-electronic markets will not be installed, I have checked, so this has nothing to do with me;
six
The fourth method: use the program management that comes with the system to check the programs on the SD card. Some programs don't actually have colored icons. It turns out that these softwares without icons are at work. These software without icons are incomplete software data that have not been installed or uninstalled correctly before. If you install them again, you will report an error. Now we use the software management that comes with the system to uninstall them, so there will be no mistakes in reinstalling the software. But I can't even see any icon with the program management of the system, so this method is useless to me.

The fifth method: directly delete/mnt/secure/asec/* * dl2tmp1.asec (in drive mode: removable disk/. Android _ secure/* * dl2tmp1.asec), and then install. This method is a supplement to the first method. Unfortunately,

The sixth method: When upgrading the installed program, you will be prompted "The application is not installed". Some software will appear when upgrading. You can only uninstall the old version and install the new version. I can't find the uninstall at all, so it's useless.
nine
The seventh method: check Settings-Development-Allow Simulation Location, and you will be happy. It's still useless for me to check this;
10
The eighth method: connect the mobile phone to the computer, then open the 9 1 mobile assistant, install an application casually, and choose the installation path as the memory of the mobile phone. I am a 2. 1 system, and the original software is installed in the "memory", so this is useless;
1 1
The ninth method: Some software signatures have changed and cannot be cover the installation. Just delete and reinstall the new version. This principle is the same as the sixth method, so it is invalid for me;
12
The tenth method: restore the factory settings directly, which is a method I don't want to do, and it should be effective in theory.

solution
After all these attempts, the problem still cannot be solved. It's really depressing. Must I go back to the factory? Hesitate again and again, I have already begun to prepare for reloading. As a result, when I was searching for the installation principle of Android system, I found a solution to this problem that has been bothering me for a long time. Let's look at the solution:
In fact, the program installation of Android system is to copy the APK file to the APP directory and give permission, and 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 in the SD card;
Rename the APK file to xxx.xxx.apk (compare the file names in the system APP directory).
Put it in the app folder, modify the permissions and install it.
Still "Program Not Installed"
At this point, all possible methods have been tried, and the solution: give up the software decisively!
What do you mean the application is not installed? According to your description, it may be the following aspects:
1. The software cannot be installed normally due to the lack of memory in the mobile phone. It is suggested that you move the multimedia files stored in your mobile phone to an external SD card to expand the memory space of your mobile phone and try to reinstall it.
2. Unknown source is not open: Set the-Security-Unknown source check box, and then try to reinstall;
3. Check whether the software format supports mobile phones. The software format supported by mobile phone is apk.

What does it mean that the APK file of mobile phone installation shows "Application not installed"? When the APK file is installed on the mobile phone, "Application not installed" is displayed, which means that the program has not been successfully installed.
There are many reasons for the unsuccessful installation. The most common thing is that APK requires your mobile phone to be android2.0 or above, but your mobile phone is actually 1.5 1.6 system, which is not supported. It is also possible that the memory of the mobile phone is full and the APK cannot be installed.
If the software is already in the mobile phone, the general mobile phone will prompt whether to replace the installed software.
"? Software/games cannot be installed on the mobile phone. The following actions are recommended:

4. The software format supported by 4.Android phone is APK, so you can download the software in other ways. For example:

3) Install 9 1 assistant, 360 assistant, etc. In your mobile phone or computer, find the needed software through this kind of software and try to download it. "
Note 2 What if there is no application installed when installing the game? Dear Samsung users:
According to your description, I suggest you try the following methods:
1. It is recommended that you uninstall and reinstall the software.
2. Change other versions or try to update the game software.
3. If other third-party software can be used normally, only this software can't have compatibility problems with the mobile phone system.
4. Update the mobile phone system version and then try to install it.
5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset-restore factory settings).
If the problem still exists, it is recommended that you send your mobile phone to the nearest Samsung service center for testing and further processing. Please visit the address and contact information of the service center:
