    <p>How in the world does Nova manage this? I'm literally trying to do exactly the same thing: provide users with a button to press to clear and pick their new default launcher. </p> <p>I'm able to get the default app name and display it: </p> <pre><code> private String getPrefered(Intent i) { PackageManager pm = this.getActivity().getPackageManager(); final ResolveInfo mInfo = pm.resolveActivity(i, 0); return (String) pm.getApplicationLabel(mInfo.activityInfo.applicationInfo); } </code></pre> <p>where <code>Intent i</code> is</p> <pre><code>Intent home = new Intent("android.intent.action.MAIN"); home.addCategory("android.intent.category.HOME"); </code></pre> <p>Then I call up the system ResolveActivity,</p> <pre><code>private void makePrefered() { Intent selector = new Intent("android.intent.action.MAIN"); selector.addCategory("android.intent.category.HOME"); selector.setComponent(new ComponentName("android", "com.android.internal.app.ResolverActivity")); startActivity(selector); } </code></pre> <p>The picker comes up and functions correctly, but it doesn't actually set or clear any values. While debugging it, it seems as if I'm missing some extras? When I call the <code>makePrefered</code> method, I get the following log message,</p> <pre><code>I/ActivityManager( 602): START {act=android.intent.action.MAIN cat=[android.intent.category.HOME] cmp=android/com.android.internal.app.ResolverActivity u=0} from pid 22641 </code></pre> <p>When I use the Nova implementation I see all of this however, </p> <pre><code> I/PackageManager( 602): Result set changed, dropping preferred activity for Intent { act=android.intent.action.MAIN cat=[android.intent.category.HOME] flg=0x10200000 (has extras) } type null I/ActivityManager( 602): START {act=android.intent.action.MAIN cat=[android.intent.category.HOME] flg=0x10200000 cmp=android/com.android.internal.app.ResolverActivity (has extras) u=0} from pid 22905 I/ActivityManager( 602): START {act=android.intent.action.MAIN cat=[android.intent.category.HOME] flg=0x10200000 cmp=com.mycolorscreen.canvas/.Launcher (has extras) u=0} from pid 22905 </code></pre> <ol> <li>How can I get in there and see what's being sent along with that bundle?</li> <li>How can I just clear the preferred app? Don't tell me you can't, I've seen enough of those answers. Nova does it and does it exactly the way that I would like to.</li> </ol>

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.
