    <p>I am working on an app that shows a google map (api v2) as a fragment. When the app loads it shows a blank white screen for a couple of seconds before showing the map. I have used log statements see where the delays is but I don't know why it's so slow.</p> <p>Here is my onCreate:</p> <pre><code>@Override protected void onCreate(Bundle savedInstanceState) { Log.i(TAG, "onCreate Start -------------------------------"); super.onCreate(savedInstanceState); Log.i(TAG, "onCreate 1 -------------------------------"); setContentView(R.layout.activity_main); Log.i(TAG, "onCreate 2 -------------------------------"); do_async_setup(); Log.i(TAG, "onCreate 3 -------------------------------"); prefs = getSharedPreferences(PREFS_NAME, 0); prefs_editor = prefs.edit(); Log.i(TAG, "onCreate Finish -------------------------------"); </code></pre> <p>And here is the output.</p> <pre><code>01-20 10:05:28.802: I/HeadsUp(19544): onCreate Start ------------------------------- 01-20 10:05:28.802: I/HeadsUp(19544): onCreate 1 ------------------------------- 01-20 10:05:30.396: I/HeadsUp(19544): onCreate 2 ------------------------------- 01-20 10:05:30.396: I/HeadsUp(19544): onCreate 3 ------------------------------- 01-20 10:05:30.403: I/HeadsUp(19544): onCreate Finish ------------------------------- </code></pre> <p>You can see a 1.5 sec delay for setContentView. Here is my layout.</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" &gt; &lt;fragment xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment"/&gt; &lt;/RelativeLayout&gt; </code></pre> <p>It's simply looks bad, like the app has frozen when loading. How can I either speed this up or hide the delay? </p> <p>thanks,</p>

    2. CO@CommonsWare , if I am reading it corectly it tells me what the logs told me. setContentView is using approx 44% of the 'time' for the onCreate method. Incl Real Time says 3211.060 which I assume are milliseconds? Also, it's ActionBarSherlockNative.setContentView() could that be why it's so slow loading the xml etc? Stepping down through the longest running child methods I get to LayoutInflater.createViewFromTag and and a few more steps SupportMapFragment.onCreateView() still at 1998ms and then into some more google gms code. So it looks like google map fragment. does that seem right?

    3. COWell, the most likely culprit would be the map, so I suppose it is not surprising. That being said, it also suggests that you are possibly just stuck. What sort of hardware are you running this on?

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.
