byte[] ops = XXXXX; //将文件保存到手机内存中。。。 //FileOutputStream fos = this.openFileOutput("test.txt" , Context.MODE_PRIVATE); //将文件保存到sd卡中 String sdcard = android.os.Environment.getExternalStorageDirectory().toString(); File dir = new File(sdcard + "/item"); dir.mkdir(); FileOutputStream fos = new FileOutputStream(sdcard+ "/item"+"/car.jpg" ); //FileOutputStream fos = new FileOutputStream(sdcard+ "/item"+"/test.txt" ); fos.write(ops); fos.close();
