1. is not compatible with the mobile phone system, so it cannot be installed. It is suggested to upgrade the mobile phone system and try downloading again;
2. The memory of the mobile phone is insufficient, and the user installs it in the memory of the mobile phone by default, so check whether the memory is full;
3. The SD card has insufficient space, so it is installed on the SD card by default. Check whether the SD card is out of space.
Why can't ZTE mobile phones install applications? I wonder what software you downloaded. Many domestic ZTE mobile phones do not support java, but may support mrp programs. Please search Baidu mrp software to see if the mobile phone supports it.
Why can't some applications be installed on mobile phones? If the phone can't install software/games, I suggest:
1. Check whether the Unknown Source setting is turned on.
2. Check whether the machine supports the downloaded software format. The software format supported by Android phones is. APK format.
3. Please read the software details when downloading the software to see if there are any requirements for the machine operating system.
4. If you still can't install the software/game, it may be because the software version is low or there are compatibility problems between the software version and the system. It is recommended to download a new version and try to install it;
5. If it is invalid, back up the data (contacts, information, photos, etc. ) and try to restore the factory settings.
If the problem still exists, please take the purchase invoice, maintenance card and machine to the service center, and the professional after-sales engineer will help you test it.
Why can't I install security privacy in the application settings on my mobile phone? The unknown source inside has been changed to allow, which means that in addition to the applications in the mobile phone application market, third-party applications can also be installed.
Why can't I install the application? Not installed. 1, the first thought is that the system has program residues, which may not be completely deleted, so it cannot be installed. So use re browser to search the relevant keywords of the program, delete all the found relevant files and directories, and then restart the installation program, the result is invalid;
2. I thought I had a backup before, so I opened the titanium backup, found the relevant software, and resumed: at first, I chose the program+data, indicating that the recovery failed, and later I chose the recovery program alone, indicating 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 whether it is effective to restart the system after recovery, so interested friends can try it ~);
There is no choice but Google. The most successful way is to connect to the computer in storage mode, or find. 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 a word, the naming format of files is obviously different from that of normal programs. Try reinstalling the software after deleting it, but I will try it on both the system and the SD card.
4. The second method: If the installation of the application prompt on the PC fails, please check whether the USB driver corresponding to the Android phone is installed first. Generally, using 9 1 mobile assistant or pea clip will automatically help you install the mobile phone driver. My mobile phone prompt failed, my driver was installed correctly, and pea pods used it normally, so this has nothing to do with me;
5. The third method: check whether the mobile phone settings-applications-unknown sources have been checked, otherwise some applications not provided by the electronic market will not be installed, I have checked, so this has nothing to do with me;
6. The fourth method: use the program management provided by the system to view 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 provided by the system to clean them up, so that there will be no mistakes in reinstalling the software. But I can't even see the icon of program management provided by the system, so this method.
7. The fifth method: directly delete/mnt/secure/asec/* * dl2tmp1.asec (in drive mode: removable disk/. Android _ secure/* * dl2tmp1.asec) and then install it. This method is a supplement to the first method.
8. 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.
9. The seventh method: Check Settings-Development-Allow Simulation Location, and it will be OK. It's still useless for me to tick this;
10, the eighth method: after connecting the mobile phone to the computer, open 9 1 mobile assistant, install an application at will, and select 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, so it can't 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 should be effective in theory.
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:
1. Download the APK installation package of the application first and put it in the SD card;
2. Rename the APK file to the form of xxx.xxx.apk (compare the file names in the system APP directory).
3. put it in the app folder, modify the permissions and install it.
4. Still "Program Not Installed"
At this point, all possible methods have been tried, and the solution: give up the software decisively!
Why can't my m9 suddenly hold many applications? Connect the computer, open the storage mode and find. Check the android_secure folder under the SD card directory to see if there is *** dl2tmp 1.asec in it, which may be a file with another name or a file with a significantly different naming format from the normal program. Delete it and reinstall the software to see if it works properly.
Why does oppo mobile phone open software suddenly show that hello has no application? This is caused by the following reasons: 1, the mobile phone does not open from unknown sources.
This is an option added by operators to ensure that users will not install unofficial applications indiscriminately, which will cause disorder in the mobile phone system. Solution: Open the location source of the mobile phone.
2. The installation software prompts insufficient memory. Solution: Free up the memory space of the mobile phone by deleting some useless third-party programs.
3. The installation position is incorrect. For example, some programs are installed in the phone memory by default when they leave the factory, which belongs to the built-in system application and can only be installed in the system space. For models supporting external SD cards such as R827T and R833T, some users will choose the "SD card" space as the preferred installation location. If the SD card is pulled out later, the installation will fail.
Solution: The preferred installation location is determined by the system.
4. The system version is too low. At present, many softwares do not support systems below 2.3, and the installation failure caused by this situation is solved by upgrading the Android version (for example, the model of U70 1 has been upgraded from 2.3 to 4.0).
5. An error occurred while parsing the installation file. The apk file is not installed, but the suffix extension has been maliciously changed by others. Solution: Download through the formal green platform and try it in the software store.
6. Problems with the software itself Due to the openness of the Android platform, there are always some softwares that are incompatible with the system, and such softwares will also fail to install. To confirm whether it is a problem of the software itself, you can compare it with other models.
If you have any other questions, you can enter the OPPO enterprise platform to ask the customer service!
