Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Android-accessing file from sdcard???

whole day i was trying to get access of a file "t.txt" that i had put in my sdcard:

 FString InPath="/mnt/sdcard/t.txt";
 FString InPath="/sdcard/t.txt";
 FString InPath="./t.txt";

then i tried to check its existence with FPaths::FileExists(InPath). but it always was returning false.

what InPath value I should have use to get proper address?

note: i also have added read permission under: project settings->android->extra permissions: android.permission.WRITE_EXTERNAL_STORAGE android.permission.READ_EXTERNAL_STORAGE
