============ Problem Description ============Because learning needs to look at the old Luo's video about the data stored in the SD card to write the part of the file to almost completely comply with the knock code results on the pad test and expected to have a difference originally should be stored in the SD card file results ran to the pad to bring in memory go ...And then I tried to write the path directly to myself or to my own memory. Why is that?

reproduce the painting. Based on this step, you can customize any gesture you want. The defined gestures will be saved to the mnt/sdcard directory: To use this gesture library, you need to export the file, select the file, click the icon in, and export it to your specified location: In this way, you can copy the exported file directly if you want to use it. Create a gesture Library: use the example GestureBuilder that comes with the SDK to creat
