How to use FileIOUtils.readFile2String function? I wrote this:
String externalString = PathUtils.getExternalStoragePath();
String testFileString = FileIOUtils.readFile2String(PathUtils.join(externalString,"test.txt"));
# i also tried:
String testFileString = FileIOUtils.readFile2String("/storage/emulated/0/test.txt");
And the testFileString is null. Could anyone tell me why? Thanks.
