I found the problem. An InputStreamReader will not read() to a
String.toCharArray(). You have to use a char[]. Here is my new
function for reference:
public String loadFile(String filename)
{
try
{
FileInputStream fis = openFileInput(filename);
InputStreamReader in = new InputStreamReader(fis,
"utf-8");
File file = new
File("/data/data/com.android.webbed/files/" +
filename);
char[] buff = new char[(int) file.length()];
in.read(buff);
String contents = new String(buff);
return contents;
}
catch(FileNotFoundException e)
{
e.printStackTrace();
return "File Not Found";
} catch (IOException e) {
e.printStackTrace();
return "IO Exception";
}
}
