How to read file from res/raw by name

android, file-io, resources

Solution

With the help of the given links I was able to solve the problem myself. The correct way is to get the resource ID with

getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
                             "raw", getPackageName());

To get it as a InputStream

InputStream ins = getResources().openRawResource(
            getResources().getIdentifier("FILENAME_WITHOUT_EXTENSION",
            "raw", getPackageName()));

Problem

I want to open a file from the folder res/raw/. I am absolutely sure that the file exists. To open the file I have tried ``` File ddd = new File("res/raw/example.png"); ``` The command ``` ddd.exists(); ``` yields FALSE. So this method does not work. Trying ``` MyContext.getAssets().open("example.png"); ``` ends up in an exception with getMessage() "null". Simply using ``` R.raw.example ``` is not possible because the filename is only known during runtime as a string. Why is it so difficult to access a file in the folder /res/raw/ ?
