There are many reasons for the installation failure of the apk program, and all of these errors are basically attributed to "errors occurred when parsing the package". Therefore, you can take the method of troubleshooting one by one to find out why the apk program cannot be installed.
1. Get apk programs through formal channels and well-known websites.
2. The apk version is incompatible. In general, when the version of the apk program downloaded from the Internet is higher than the current version of the mobile phone, the warning "Error occurred when parsing the package" will appear when installing the program. The solution to this kind of situation is to search the Android market for the app of the same kind, but the version should not be higher than the current mobile phone version, to download, install and use this apk program.
3. The apk program is incomplete. Some mobile phones have their own download tools that do not have the breakpoint resume function, so the downloaded programs may not be completely downloaded, and some programs may be lost first. For such problems, it is recommended to download it again, or download it through a computer, and then copy the apk program to the mobile phone memory card with the help of the data cable for installation.
4. The current phone does not support Chinese names or paths, and does not support long file names. The solution is to rename the file, and the name only contains English letters (note that the ". apk" name should be reserved), such as "abc. apk", and then move the installer again after the change.
5. The apk program cannot be installed normally due to the insufficient memory of the phone, poor contact of the phone memory card, poor quality of the memory card, and other factors. For this kind of problem, try to re insert and unplug the mobile phone's extended memory card. If you can't, replace it with a high-quality memory card.
