the documentation for context.getExternal... (i.e.:
context.getExternalFilesDir, context.getExternalCacheDir())
tells there is NULL returned if no external storage is available
this leads to a problem for calls like this:
context.getExternalFilesDir(null).getParentFile();
context.getExternalFilesDir(null) returns null and there is a call to
null.getParentFile(); which throws NullPointerException
