How to get files in cache directory in android?

Question

In my android app, I make files in a directory I get using this function (notice its putting in a subdirectory).

gsFile = new File(getCacheDir(), "test/aa.txt");

But how do I iterate through the files in that directory now?

I tried

File dir = new File(getCacheDir(), "test/aa.txt");
for (File f : dir.listFiles()) {

}

but it crashed on File f

Change your code like this and try..

    File dir = new File(getCacheDir(), "test");
    if (dir.exists()) {
        for (File f : dir.listFiles()) {
            //perform here your operation
        }
    }
