How to copy a large number of pre-installed apk files in Android recovery

A large number of third-party apps are required to be pre-installed in the product. The apk file is larger than MB, and the related resource files are added, totaling 4 GB.

How to Build so many files into the system during installation becomes a problem. Solution 3: 1. Copy Data in update.zip. Write updater-script and copy it by using script. See my other custom updater-script article. Disadvantage: the script must be written by yourself and cannot be generated with make. 2. copy the file in update.zip. Implemented in recovery. c. Disadvantage: SDCARD fat has a limit on the size of zip files. 3. Automatic Installation is enabled after the first system startup. Disadvantage: It is too slow. It takes about 30 minutes. Implementation of Method 2:
