First, please check whether you are allowed to install applications from unknown sources. Please check "Unknown Sources" in Settings-Security. Only by checking "unknown source" can you install software on your mobile phone through pea pods.
If you are prompted with "signature conflict" when installing the application, please check whether the software with the same name is installed in your mobile phone. If two software packages have the same name but different signatures, they will encounter the problem that they cannot be installed.
If you are prompted "Error parsing program" during installation, please enter the directory of wandoujia/app file, temporarily delete the apk file of the application that cannot be installed, and then reinstall the next file. This is usually because the file you downloaded has errors and cannot be successfully installed.
