I am writing one of my first apps where the idea is that user inputs a number into a getText, clicks a button which adds the users input to previous results and shows this to the screen. I've tried storing the data in SharedPreferences and it works when the user presses the home button and then comes back into the app, but the app crashes if they press the back button and then comes back into the app. Any advice? <pre><code>public class Calc extends Activity { int points = 0; SharedPreferences data; public static String filename = "Points"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); data = getSharedPreferences(filename, 0); points = data.getInt("key", 0); final TextView myTextView = (TextView) findViewById(R.id.mytextview); myTextView.setText("" + points); Button Button = (Button) findViewById(R.id.add); final EditText Edit = (EditText) findViewById(R.id.input); Button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { int temp = 0; try { temp = Integer.parseInt(Edit.getText().toString()); } catch (NumberFormatException nfe) { System.out.println("Could not parse " + nfe); } points = points + temp; if (points > 9999) { myTextView.setText("10000+"); } else { myTextView.setText("" + points); } Edit.setText(""); SharedPreferences.Editor editor = data.edit(); editor.putInt("key", points); editor.commit(); } }); } } </code></pre> crash log: <pre><code>05-19 03:24:02.352: D/dalvikvm(1120): GC_EXTERNAL_ALLOC freed 759 objects / 55808 bytes in 63ms 05-19 03:24:05.812: D/dalvikvm(1120): GC_EXTERNAL_ALLOC freed 193

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
