今天調(diào)用安卓系統(tǒng)文件之后獲取文件路徑突然出現(xiàn)了異常，不知道是什么情況庙睡，安卓版本5.1事富，先看代碼：

1.調(diào)用系統(tǒng)文件管理器

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
startActivityForResult(intent,0);

2.onActivityResults處理結(jié)果

filePath = UtilTools.getPath(getActivity(),intent.getData());

3.UtilTools

引用自CSDN論壇-Android 4.4前后版本讀取圖庫(kù)圖片和拍照完美解決方案
