need to write a method
public void
saveFile(Bitmap bm, String fileName)
throws
IOException { File dirFile =
new
File(Environment.
getExternalStorageDirectory
().getPath());
if
(!dirFile.exists()) { dirFile.mkdir(); } fileName = UUID.
randomUUID
().toString() +
".jpg"
; File jia =
new
File(Environment.
getExternalStorageDirectory
().getPath() +
"/imgpic/"
);
if
(!jia.exists()) {
//判断文件夹是否存在，不存在则创建
jia.mkdirs(); } File myCaptureFile =
new
File(jia +
"/"
+ fileName); BufferedOutputStream bos =
new
BufferedOutputStream(
new
FileOutputStream(myCaptureFile)); bm.compress(Bitmap.CompressFormat.
JPEG
,
80
, bos); bos.flush(); bos.close(); }
Then put it in the resources you need to put,
saveFile(
bitmap
, Environment.
getExternalStorageDirectory
() +
"/imgpic/"
);
This bitmap can be an image or a file
