The invention discloses a plug-in loading processing method. The method includes the steps that when a plug-in shared library of a plug-in application program is initialized, a character string corresponding to function symbols of a set function in a character string table of the plug-in shared library is modified into a character string corresponding to function symbols of a function existing in a system library; in the plug-in loading process, the plug-in shared library with the modified character string table is loaded; the loaded plug-in shared library is called for executing operation. The invention provides a plug-in loading processing device correspondingly. According to the scheme, a browser can load plug-ins normally on an Android 4.4 platform or a platform with a higher version.
