    <p>I've tried to create a widget that, on click calls a routine on Configuration activity, on update calls another routine on Configuration activity, update must be under 30 minutes and all the instance created must work separately (in onUpdate and in onClick).</p> <p>The code below: Click doesn't work (Can't See Toast Message and other function) Update works fine for first instance but with multiple widget instance it works bad: If i create 2 instances between 10 seconds (and refresh is set to 20 seconds) all will update every 10 seconds.</p> <p>That's my Manifest:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="it.fraschi.controllogiardinowg" android:versionCode="1" android:versionName="1.0" &gt; &lt;uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" /&gt; &lt;application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" &gt; &lt;activity android:name="it.fraschi.controllogiardinowg.Configurazione" android:label="@string/app_name" &gt; &lt;intent-filter&gt; &lt;action android:name="android.appwidget.action.APPWIDGET_CONFIGURE"/&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;receiver android:name="it.fraschi.controllogiardinowg.ControlloWidget" android:label="@string/app_name"&gt; &lt;intent-filter&gt; &lt;action android:name="android.appwidget.action.APPWIDGET_UPDATE" /&gt; &lt;/intent-filter&gt; &lt;intent-filter&gt; &lt;action android:name="it.fraschi.controllogiardinowg.ControlloWidget.ACTION_WIDGET_CLICKED"/&gt; &lt;/intent-filter&gt; &lt;intent-filter&gt; &lt;action android:name="it.fraschi.controllogiardinowg.ControlloWidget.MY_OWN_WIDGET_UPDATE" /&gt; &lt;/intent-filter&gt; &lt;meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_provider" /&gt; &lt;/receiver&gt; &lt;/application&gt; &lt;/manifest&gt; </code></pre> <p>That's my Configuration:</p> <pre><code>package it.fraschi.controllogiardinowg; import java.util.Calendar; import java.util.Random; import android.os.Bundle; import android.app.Activity; import android.app.AlarmManager; import android.app.PendingIntent; import android.appwidget.AppWidgetManager; import android.content.Context; import android.content.Intent; import android.content.SharedPreferences; import android.view.Menu; import android.view.View; import android.view.View.OnClickListener; import android.widget.AdapterView; import android.widget.Button; import android.widget.EditText; import android.widget.RemoteViews; import android.widget.Spinner; import android.widget.Toast; import android.widget.AdapterView.OnItemSelectedListener; public class Configurazione extends Activity { private static final String PREFS_NAME = "it.fraschi.android.ControlloGiardinoWG"; public static final String NOME = "nome_"; private static long millis = 60000; private int mAppWidgetId = AppWidgetManager.INVALID_APPWIDGET_ID; private int selectedTextColor; private int selectedBackgroundColor; public Configurazione() { super(); } @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); // Set the result to CANCELED.

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).
