    <p>In my application, I create alarms. So, when the phone is rebooted, I need to create again the alarms.</p> <p>But when I reboot the phone (emulator) and that alarms must be created, there is a Force Close. It says : </p> <pre><code>Unable to instantiate receiver com.yannv.vehiclesmanager.AlarmReceiver: java.lang.ClassNotFoundException: com.yannv.vehiclesmanager.AlarmReceiver in loader dalvik.system.PathClassLoader[/data/app/com..etc] </code></pre> <p>Here is the concerned part of my manifest (don't know if problem comes from there..)</p> <pre><code> &lt;receiver android:name="AlarmReceiver"&gt; &lt;intent-filter&gt; &lt;action android:name="afficherNotification" /&gt; &lt;data android:scheme="rappel" /&gt; &lt;/intent-filter&gt; &lt;/receiver&gt; &lt;receiver android:name="com.yannv.vehiclesmanager.BootReceiver"&gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.BOOT_COMPLETED" /&gt; &lt;/intent-filter&gt; &lt;/receiver&gt; &lt;/application&gt; &lt;uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /&gt; </code></pre> <p></p> <p>Thanks for your help</p> <p>BootReceiver Class :</p> <pre><code>package com.yannv.vehiclesmanager; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Date; import android.app.AlarmManager; import android.app.PendingIntent; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.database.Cursor; public class BootReceiver extends BroadcastReceiver{ /*Lorsqu'on éteint le téléphone, les alarmes sont supprimées.

It seems that all my problems came from this line of the BootReceiver class:</p> <pre><code>jour = dateRappel.getDay(); </code></pre> <p>I replace it by </p> <pre><code>jour = dateRappel.getDate(); </code></pre> <p>And it works.</p>

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).
