Android - Clickable Widget - Working on emulator, but not on phone

I tried to create clickable widget on android. I was looking for solution on this site and I found it, but finally this widget is working only on the emulator - not on real phone. This is my code:
AppWidgetProvider:
public static String WIDGET_BUTTON = "apps.test.widget.WIDGET_BUTTON";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.main);
Intent clickIntent = new Intent(WIDGET_BUTTON);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0,
clickIntent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.imageView1, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, views);
}
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if (WIDGET_BUTTON.equals(intent.getAction())) {
Toast.makeText(context, "asdfsdgdasfg", Toast.LENGTH_SHORT).show();
}
}
Manifest:
<application
android:allowBackup="true"
android:icon="#drawable/image"
android:label="#string/app_name" >
<receiver
android:name=".Widget"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="apps.test.widget.WIDGET_BUTTON"/>
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/test_widget_provider" />
</receiver>
</application>
Toast is showing up on the emulator but not on phone.

Ok, nevermind.
I had to reset the phone to factory settings. I don't know what was wrong.

This is a common issue,had it a few times with my phone , if the app is installed on sdcard instead of internal storage ,the widget does not appear on the list,
you can simply go to Settings->apps->find the app and then select the option to move it to internal storage from your android itself.

There is another way to declare in the manifest as android:externalstorage(syntax isnt correct) which works as well (I cant find the link though to the answer and I have not tried it)

I've created a simple widget have only a button and textView. When I add my widget first time to the homescreen a FC message coming and widget will added. And button click toast message won't work. Only i need to have a toast message when clicking the widget button. I've gone through lots of tutorials but couldn't figure out whats the problem. Any genius who'd like to help..really appriciate the help..Thanks..
widgetProvider.java
public class widgetProvider extends AppWidgetProvider{
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
final int N = appWidgetIds.length;
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
Intent intent = new Intent(context, widgetProvider.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widgetlayout);
views.setOnClickPendingIntent(R.id.button1, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(AppWidgetManager.ACTION_APPWIDGET_UPDATE)) {
Toast.makeText(context, "Button Clicked", Toast.LENGTH_SHORT).show();
}
}
}
AndroidManifest.xml
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<receiver android:name=".widgetProvider" android:label="#string/app_name">
<intent-filter >
<action
android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/widgetprovider" />
</receiver>
</application>

your onUpdate is never called since you overriden the onReceive method.

Android: Widget onReceive() not getting called

I have a widget whose layout has an imageView. The view needs to be changed based on some activity. So, whenever that happens, I am calling a sendBroadcast() with the action set to UPDATE_WIDGET. However, the onReceive() in the widget code is not getting called. Below is my code.
public class TaskWidget extends AppWidgetProvider {
...
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "widget update", 2000).show();
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.searchwidget);
if (intent.getAction().equals(UPDATE_WIDGET)) {
views.setImageViewResource(R.id.newImage, R.drawable.Pic1);
}
super.onReceive(context, intent);
}
}
In the manifest,
<receiver
android:name="com.rahul.testwidget.TaskWidget"
android:label="Task Widget" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="com.rahul.UPDATE_WIDGET" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/widget" />
</receiver>

you have to update your widget layout
use this code just befor super.onReceive(context, intent);
ComponentName widget = new ComponentName(context, SimpleWidget.class);
AppWidgetManager.getInstance(context).updateAppWidget(widget, views);

I think your action name must be com.rahul.UPDATE_WIDGET instead of UPDATE_WIDGET.

If you are sending the broadcast from a listener on your widget you need to create a PendingIntent for a Broadcast.
PendingIntent sentPI = PendingIntent.getBroadcast(activity, 0, intent,PendingIntent.FLAG_CANCEL_CURRENT);
Also, you don't seem to be able to attach 2 pending intents to a button in the widget.

Android App Widget button click not working properly

I am making a simple app widget that displays a toast message when a button in the widget is touched. The issue I am having is that the toast never appears when the button is clicked. In fact, the onReceive event is never fired when the button is touched. I suspect the issue has to do with my manifest, but it looks ok to me.
Here is the relevant portions of my manifest:
<receiver android:name=".GPSWidget" android:label="GPS Receiver">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="luke.app.steal.GPSWidget.ACTION_WIDGET_RECEIVER"/>
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/widget_provider" />
</receiver>
Here is the code to "wire up" the button to an event listener, as well as the onReceive event it is in a class called GPSReceiver.
public static String ACTION_WIDGET_RECEIVER = "ActionReceiverWidget";
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(ACTION_WIDGET_RECEIVER)) {
Toast.makeText(context, "Button hit", Toast.LENGTH_SHORT).show();
}
super.onReceive(context, intent);
}
#Override
public void onUpdate( Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds )
{
RemoteViews remoteViews;
remoteViews = new RemoteViews( context.getPackageName(), R.layout.gpswidget );
remoteViews.setTextViewText( R.id.widgetTexts, "Click Me!");
Intent inte = new Intent(context, lukeService.class);
inte.setAction(ACTION_WIDGET_RECEIVER);
PendingIntent configPendingIntent = PendingIntent.getBroadcast(context, 0, inte, 0);
remoteViews.setOnClickPendingIntent(R.id.widgetTexts, configPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews );
}
widgetTexts is the button that should be launching the toast, but like I said nothing happens when the button is hit. I thought that my path in the manifest was wrong, luke.app.steal, but that same path works just fine for all my other activities.
Anyone got any ideas? or need more info?

Android alarm not being triggered

I"m sure this is something that is simple, but I'm not figuring it out. I'm trying to make a simple repeating alarm and it never gets triggered. What I have is:
private void setupAlarms()
{
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Intent intent = new Intent(this, RepeatingAlarm.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(HelloAndroid.this, 0, intent, 0);
GregorianCalendar fifteenSeconds = (GregorianCalendar)Calendar.getInstance();
fifteenSeconds.add(Calendar.MINUTE, 0);
fifteenSeconds.set(Calendar.SECOND, 15);
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime(), fifteenSeconds.getTimeInMillis(), pendingIntent);
}
This is called from the main onCreate call.
My alarm receiver:
public class RepeatingAlarm extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
Toast.makeText(context, R.string.hello, Toast.LENGTH_SHORT).show();
}
}
In my manifest, I have added:
<receiver android:name=".RepeatingAlarm" android:process=":remote" />
Any help, much appreciated

Have you added an intent filter to your BroadcastReceiver?
Code might look something like this in your AndroidManifest.xml file:
<receiver android:name=".RepeatingAlarm" android:exported="true">
<intent-filter>
<action android:name="intent id text" />
</intent-filter>
</receiver>
and when creating your intent do something like this:
Intent intent = new Intent("intent id text")
where the "intent id text" can be any string you use to identify your intent. Also Android alarms get reset if you reboot your device so that may be something you need to look into.
Hope this helps.
