    <p>I believe <code>basket</code> is <code>null</code>. You need to initialize it before callling <code>put()</code> on it</p> <pre><code>Bundle basket = new Bundle(); </code></pre> <p>Knowing how to read the logcat is imperative for debugging your work. Looking at the above output</p> <pre><code>04-25 19:04:11.912: E/AndroidRuntime(999): FATAL EXCEPTION: main 04-25 19:04:11.912: E/AndroidRuntime(999): java.lang.NullPointerException 04-25 19:04:11.912: E/AndroidRuntime(999): at com.example.assignment2.MainActivity$5.onClick(MainActivity.java:121) </code></pre> <p>from here we see that there is a <code>NPE</code> at line 121 of <code>MainAcitivty</code></p> <p>*Edit**</p> <p>In <code>Second</code> change the way you get your extras. Change</p> <pre><code>Intent i = getIntent();//MAking an intent called i Bundle basket = this.getIntent().getExtras(); </code></pre> <p>to </p> <pre><code>Intent i = getIntent();//MAking an intent called i Bundle basket = i.getBundleExtra("basket"); </code></pre> <p>Since you are putting the <code>Bundle</code> into the <code>Intent</code> instead of each <code>extra</code> itself, you do it this way. If you had put each <code>extra</code> in there then you would get a <code>Bundle</code> the way you currently have it. </p> <p><a href="https://stackoverflow.com/questions/9577024/what-is-the-difference-between-getextras-and-getbundleextras">See this so answer</a> (the second one) it may make it more clear.</p> <p>In your first <code>Activity</code> change </p> <pre><code>intent.putExtras(basket); </code></pre> <p>to</p> <pre><code>intent.putExtra("basket", basket); </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
