Android exception handling best practice?

Here, check for the link for reference.

In here you create a class say ExceptionHandler that implements java.lang.Thread.UncaughtExceptionHandler..

Inside this class you will do your life saving stuff like creating stacktrace and gettin ready to upload error report etc....

Now comes the important part i.e. How to catch that exception. Though it is very simple. Copy following line of code in your each Activity just after the call of super method in your overriden onCreate method.

Thread.setDefaultUncaughtExceptionHandler(new ExceptionHandler(this));

Your Activity may look something like this…

public class ForceClose extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Thread.setDefaultUncaughtExceptionHandler(new ExceptionHandler(this));

        setContentView(R.layout.main);
    }
}

Hope this helps...

You could just use a generic alert dialog to quickly display error messages. For example...

//******************************************
//some generic method
//******************************************
private void doStuff()
{       
    try
    {
        //do some stuff here
    }
    catch(Exception e)
    {
        messageBox("doStuff", e.getMessage());
    }
}


//*********************************************************
//generic dialog, takes in the method name and error message
//*********************************************************
private void messageBox(String method, String message)
{
    Log.d("EXCEPTION: " + method,  message);

    AlertDialog.Builder messageBox = new AlertDialog.Builder(this);
    messageBox.setTitle(method);
    messageBox.setMessage(message);
    messageBox.setCancelable(false);
    messageBox.setNeutralButton("OK", null);
    messageBox.show();
}

You could also add other error handling options into this method, such as print stacktrace
