安卓API 19以上如何发送文件？

protected void selectFileFromLocal() { 
Intent intent = null; 
if (Build.VERSION.SDK_INT < 19) { 
//api 19 and later, we can't use this way, demo just select from images 
intent = new Intent(Intent.ACTION_GET_CONTENT); i
ntent.setType("*/*"); 
intent.addCategory(Intent.CATEGORY_OPENABLE); 
} else { 
intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
} 
startActivityForResult(intent, REQUEST_CODE_SELECT_FILE); 
}
 
 
官方的demo里说，api 19以上就不能用那种方式获取文件了，那该怎么办呢？
