Basic localization

By default in Android all of your static text is in a separate file called strings.xml. This lends itself very neatly to localization. I will just look at localization of strings here. Images, currency, time etc. are more complex but also well supported.
First create your application as you normally would with your strings in their own xml file. Next using eclipse right click on your project and select New/Android XML file. In the dialog enter strings.xml as the file name (it won't clash with your existing strings it is going in a separate folder). Select 'language' as the resource configuration and enter the 2 letter code that corresponds to the language you are after. de for German in my case.
Click finish. Next you need to translate that text. I just took the whole xml file and pasted it into the input box on Google Translate. It does not mess with your ids as they have underscores in them. It translated most of my text into German. The rest I just manually pasted in there to get the values and edited the file. Also note that Google Translate tries to format your output nicely and so it capitalizes some stuff and inserts some unhelpful spaces in xml tags. Just edit these by hand. If you are translating a big file a bit of search and replace might be in order.
Now paste this fixed up German language version of  the strings into the strings.xml file that the wizard created for you.
Run the app on your emulator. It will be in your base language whatever that is. Hit home on your emulator. Then open the drawer (this will vary by emulator, but I am using the latest one so probably best for examples) and click on Custom Locale. Select the locale you want to check here. Then run your program (I ran it again from Eclipse, but if you have configured your app to have the appropriate intent filter in your manifest you can restart from the launcher).

Building a choropleth map for Irish agricultural data

I wanted to create a choropleth map  using Irish data. The Irish Government has made a large quantity of data available at data.gov.ie. The set I chose was for Bovine TB across Ireland over a number of years. You can get geojson for a variety of countries and Ireland's county boundaries are available. All I had to do was get the data labels to match. In the data some counties are split into 2 parts. I merged and summed these data points to get the choropleth to work with normal county boundaries. You can see the results here . A link to the github is included at the top of the notebook.

Early Stopping with Keras

Steps to train a model There are a number of things you have to do when working on a Machine Learning problem. Import your data and transform it as appropriate Define  your model using something like Keras - this includes your chosen hyperparameter values Run the training phase Evaluate the model If at the end of this process the evaluation shows that your model is not sufficient for your needs you will need to make some changes and rerun the training.  Ideally you should have a way to spot that training is not going as you want and stop it. This is one of the uses of early stopping. The other is if your model has reached a sufficient quality standard for you to use and further improvements have slowed, stopped altogether or an unnecessary.  Early Stopping Keras provides a way of doing this using the EarlyStopping callback . There are a range of callbacks in Keras and you can define your own. Details are here . The EarlyStopping callback works by choosing a metric

AutoCompleteTextView backed with data from SQLite in Android

Image
This is a handy piece of code. As your database gets bigger you can allow the user to pick the correct value by typing. If the db gets very big, you can always increase the threshold, so that the query does not run until there will be a suitably sized resultset returned. Running it at a threshold of 1 is fine for very small resultsets.  Here is the code you need to back your AutoCompleteTextView with a cursor adapter. @Override protected void onResume() { super.onResume(); text = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1); final AdapterHelper h = new AdapterHelper(this); Cursor c = h.getAllResults(); startManagingCursor(c); String[] from = new String[] { "val" }; int[] to = new int[] { android.R.id.text1 }; CursorAdapter adapter = new MyCursorAdapter(this, android.R.layout.simple_dropdown_item_1line, c, from, to); adapter.setFilterQueryProvider(new FilterQueryProvider() { public Cursor runQuery(Cha
