First I get the root directory path under the SD card:privatestring Issdcard () { File sdcarddir=null; Boolean issdexist=environment.getexternalstoragestate (). Equals (environment.media_mounted); if (issdexist) { // If there is sdcard, locate the directory sdcarddir= Environment.getexternalstoragedirectory (); return sdcarddir.tostring (); }else { returnnull;}}

For example, this requirement is not a complicated process, but there are some hidden risks. I recently encountered this problem in the project, I made a small research on Android's image acquisition through a camera or album and finally displayed on the interface.
