Android Android Data Persistence Introduction to Data Persistence Handling an Exception

I have called printStackTrace() in my catch block (ge.printStackTrace()), but the compiler keep asking me to call it.

I have even added an IOException to catch the exception thrown by copyFile but it keeps asking me to printStackTrace().

It would helpful if you could paste the code snippet that is causing the error.

I haven't done any of the videos, but I am a Java developer. As far as I can tell something is not right from their end. This is my code:

try {
  InputStream in = assetManager.open(assetName);
  FileOutputStream out = new FileOutputStream(fileToWrite);
  copyFile(in, out);
}
catch(Exception exception) {
  exception.printStackTrace();
}

Yet it also keeps asking me to call it. In fact, if I try to catch IOException and then Exception I get no error. So Joseph, I don't think what you are doing is wrong.

Oh, and after I thought about it some more and looked at the error:

JavaTester.java:45: error: unreported exception IOException; must be caught or declared to be thrown
  copyFile(in, out);
          ^
1 error

I think the issue is in the method copyFile(). It needs to throw an IOException. It doesn't, so we can't catch it. The error is in code we can't access.

Thanks to you all for the great help :)

Sorry all! Looks like I introduced some sort of bug in that challenge. This should now be fixed.
