Appwidget Never go to onUpdate
My app widget Never go to the onUpdate function I add 3000 mili for testing but other than the first time you add it it never goes to the onUpdate function.
what am I doing wrong?
my manifest file:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="layout.ClockWidgetClass">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="@xml/clock_widget_class_info" />
</receiver>
</application>
my clockWidget:
/**
* Implementation of App Widget functionality.
*/
public class ClockWidgetClass extends AppWidgetProvider {
static void updateAppWidget(final Context context, final AppWidgetManager appWidgetManager,
final int appWidgetId) {
//getting shered prefrences
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
String name = preferences.getString("randomString", "");
if(!name.equalsIgnoreCase(""))
{
name = name; /* Edit the value here*/
}
// Construct the RemoteViews object
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.clock_widget_class);
//set chosen design visible
//set all visibility to 0
views.setViewVisibility(R.id.AnalogClock0, View.INVISIBLE);
views.setViewVisibility(R.id.AnalogClock1, View.INVISIBLE);
views.setViewVisibility(R.id.AnalogClock2, View.INVISIBLE);
views.setViewVisibility(R.id.AnalogClock3, View.INVISIBLE);
//turning on the correct clock
if (name.equals("1")) {
views.setViewVisibility(R.id.AnalogClock0, View.VISIBLE);
} else if (name.equals("2")) {
views.setViewVisibility(R.id.AnalogClock1, View.VISIBLE);
} else if (name.equals("3")) {
views.setViewVisibility(R.id.AnalogClock2, View.VISIBLE);
} else {
views.setViewVisibility(R.id.AnalogClock3, View.VISIBLE);
}
// views.setTextViewText(R.id.appwidget_text, name);
//updateting the widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
// There may be multiple widgets active, so update all of them
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
}
@Override
public void onEnabled(Context context) {
// Enter relevant functionality for when the first widget is created
}
@Override
public void onDisabled(Context context) {
// Enter relevant functionality for when the last widget is disabled
}
@Override
public void onReceive(Context context, Intent intent) {
// Chain up to the super class so the onEnabled, etc callbacks get dispatched
super.onReceive(context, intent);
// Handle a different Intent
Log.d("reciving", "onReceive()" + intent.getAction());
}
}
my Widget XML file:
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:initialKeyguardLayout="@layout/clock_widget_class"
android:initialLayout="@layout/clock_widget_class"
android:minHeight="110dp"
android:minWidth="250dp"
android:previewImage="@drawable/example_appwidget_preview"
android:resizeMode="horizontal|vertical"
android:updatePeriodMillis="3000"
android:widgetCategory="home_screen"></appwidget-provider>

Can never be right. It just doesn't happen at a time when you expect it to happen. You will find an important note in the documentation forupdatePeriodMillis
:
Note . Updates requested with help
updatePeriodMillis
will not be sent more than once every 30 minutes.
Thus, you may need to wait for this 30 minutes before the next call occurs onUpdate()
.
