获得SDCard的路径
在android中获得sd卡的路径太常用了，那么如何获得sd卡的路径呢？
public String getSDPath(){
File sdDir = null;
boolean sdCardExist = Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED);//判断sd卡是否存在
if(sdCardExist) {
sdDir = Environment.getExternalStorageDirectory();//获取跟目录
}
return sdDir.toString();
}
