Fig. 4 is a schematic diagram of system level font switching in the related art, and as shown in fig. 4, the basic idea of the font switching method in the related art is to directly replace the font/system/fonts/file in the system. Android system font files all exist in system partitions, and directly replacing font. However, system partition data is of great importance, protective measures are set before the mobile phone leaves a factory, and general programs and users have no permission to modify the data unless the root permission is obtained by a third-party tool in a forced mode to modify the data directly, so that great potential safety hazards are brought.

<font weight＝"400"style＝"normal">CustomFont.lnk</font>
Secondly, a primary link is newly added in a system font storage directory/system/fonts/through a script, copying and other modes, the naming is consistent with the self-defined name in the step I, such as CustomFont. lnk, the file actually pointed by the link is a file B under a special work directory in a user data/data partition, such as/data/fontDir/B, the file B can be a specific font file (in a format of ttf/ttc/otf and the like) or a link file, and finally other effective font files can be pointed.
Note that before the font switching operation is not performed by the user or after the font switching is cancelled, in order to ensure that the font display is normal, the B file points to the default font in the Android original font storage directory by default, such as/system/fonts/Roboto-regular.
And presetting a user operation entrance, such as a special app or other related setting interfaces. This interface is responsible for modifying the/data/fontDir/B file, modifying the font file it actually points to.
After the mobile phone leaves the factory: after purchasing a mobile phone, if the system font needs to be switched, the user selects the required custom font through the operation entry preset by the system, and the system completes the font switching work.
