Body
I'm trying to trace AOSP code from the <a href="http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/4.1.1_r1/android/content/Context.java?av=f" rel="nofollow">grepcode site</a>. When I call <code>getSystemService(Context.WIFI_P2P_SERVICE)</code>, it gets to the following code: <pre><code> @Override public Object getSystemService(String name) { if (getBaseContext() == null) { throw new IllegalStateException( "System services not available to Activities before onCreate()"); } if (WINDOW_SERVICE.equals(name)) { return mWindowManager; } else if (SEARCH_SERVICE.equals(name)) { ensureSearchManager(); return mSearchManager; } return super.getSystemService(name); } </code></pre> And since <code>WIFI_P2P_SERVICE</code> declared as <code>public static final String WIFI_P2P_SERVICE = "wifip2p";</code>, if will not fall in one of the conditions and will go to the <code>super.getSystemService(name);</code> <pre><code>Activity extends ContextThemeWrapper, the code there is: @Override public Object getSystemService(String name) { if (LAYOUT_INFLATER_SERVICE.equals(name)) { if (mInflater == null) { mInflater = LayoutInflater.from(mBase).cloneInContext(this); } return mInflater; } return mBase.getSystemService(name); } </code></pre> Here also, the required service name will not match, <code>mBase</code> is an instance of <code>Context</code> so the code in Context is: <pre><code>public abstract Object getSystemService(String name); </code></pre> which means that classes which extends from it must handle that functionality. Well, Where my request is being treated?

1. COOn grepcode.com, between `Object` and `getSystemService(` there is a down arrow, click it and select "Find derived methods". It will bring you to the interface's implementation.

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.
