Android widget ListView item clicks not working

So I'm trying to set up a widget with a list but clicks aren't working, so I understand to do this I need a template pending intent as individual items cannot have their own, and then add to the pending intent template using a fill in intent, I've added all this to my app but it still isn't working, I've followed advice here and here but when I click on an item its just highlighted to show it has registered a click and does nothing but I do get this in the
logcat

so here is my code, my onUpdate method calls a static update widget method that defines my template pending intent, and my onReceive method
AppWidgetProvider
public class MessageMeAppWidget extends AppWidgetProvider {
private static final String TAG = "MsgMeWdgt";
#Override
public void onReceive(Context context, Intent intent) {
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
if (intent.getAction().equals(Constants.LAUNCH_ACTIVITY)) {
int appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
//String recipientId = intent.getStringExtra(Constants.FS_ID);
//String recipientName = intent.getStringExtra(Constants.FS_NAME);
Intent i = new Intent(context, MessageListActivity.class);
Bundle b = new Bundle();
//b.putString(Constants.FS_ID, recipientId);
//b.putString(Constants.FS_ID, recipientName);
i.putExtras(b);
Bundle bundle = intent.getExtras();
String toastText = "position is " + bundle.getInt(Constants.LAUNCH_ACTIVITY);
Toast.makeText(context,toastText,Toast.LENGTH_SHORT).show();
//context.startActivity(i);
}else if(intent.getAction().equals(Constants.DONT_LAUNCH_ACTIVITY)){
//Toast.makeText(context,"",Toast.LENGTH_SHORT).show();
}
super.onReceive(context, intent);
}
public static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId) {
SharedPreferences sharedPreferences = context.getSharedPreferences(Constants.SHARED_PREFS,Context.MODE_PRIVATE);
boolean userSignedIn = sharedPreferences.getBoolean(Constants.SIGNED_IN, false);
if (userSignedIn){
//move everything in here after i know its working
}
Intent intent = new Intent(context, MessagingService.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_list_view);
//populates data
remoteViews.setRemoteAdapter(R.id.widget_list,intent);
//remoteViews.setRemoteAdapter(appWidgetId, R.id.widget_list, intent);
remoteViews.setEmptyView(R.id.widget_list,R.id.empty);
Intent launchIntent = new Intent(context, WidgetAdapter.class);
launchIntent.setAction(Constants.LAUNCH_ACTIVITY);
launchIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
PendingIntent launchPendingIntent = PendingIntent.getBroadcast(context, 0, launchIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setPendingIntentTemplate(R.id.widget_list, launchPendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
// There may be multiple widgets active, so update all of them
Log.d(TAG,"on update");
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
}
Then my widget service is standard
public class MessagingService extends RemoteViewsService {
private String TAG = "MsgSrvc";
#Override
public RemoteViewsFactory onGetViewFactory(Intent intent) {
Log.d(TAG,"item clicked");
return new WidgetAdapter(this.getApplicationContext(), intent);
}
}
and then in the getViewAt method of my widget adapter I fill my fill in intent like this
Bundle extras = new Bundle();
extras.putInt(Constants.LAUNCH_ACTIVITY, position);
Intent fillInIntent = new Intent();
fillInIntent.putExtras(extras);
remoteViews.setOnClickFillInIntent(R.id.holder, fillInIntent);
in my manifest I'm registering my widget service and the receiver
<receiver android:name="com.sealstudios.aimessage.MessageMeAppWidget">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/message_me_app_widget_info" />
</receiver>
<service android:name=".MessagingService"
android:permission="android.permission.BIND_REMOTEVIEWS" />
any help appreciated

i fixed this it wasthe intent was pointing to the wrong class so
Intent launchIntent = new Intent(context, WidgetAdapter.class);
should have been
Intent launchIntent = new Intent(context, MessageMeAppWidget.class);

Android - Appwidget with Remoteviews not updating after reboot

I saw similar questions here on SO, but nothing seems to work in my case...
I created an appwidget with an AdapterViewFlipper (Simple ViewAnimator that will animate between two or more views that have been added to it). The appwidget has a Next button that enables the user to navigate to the next view on the widget.
It all works fine when I first add the appwidget. But if the smartphone reboots, the Next button of the widget no longer works on my Samsung S4 (the method onReceive is called, but nothings happens, it doesn't navigate to the next view and is stuck at the first view). I have to delete the widget and add it again in order for it to work...
I suspect that it is a problem of Touchwiz since I tested it on another phone (Moto G) and it worked fine.
Here are some portions of my code :
AppWidgetProvider
public class AppWidgetProvider extends AppWidgetProvider {
public static final String NEXT_ACTION = VersionUtil.getPackageName() + ".action.NEXT";
private static final String TAG = DailyAppWidget.class.getSimpleName();

Any help would be appreciated !

Depends on the launcher, there is no guarantee that your AppWidget will be updated immediately after the device started. It may be refreshed immeidately, or wait till the updatePeriodMillis passed after system started.
To solve your problem, define a BroadcastReceiver that will trigger the update of AppWidget after the reboot.
In AndroidManifest.xml, define the BootReceiver to get the boot_complete message.
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver android:name=".BootReceiver" android:enabled="true" android:exported="false" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
And define the BootReceiver.java to start your AppWidgetUpdateService
public class BootReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent){
//start appwidget update service
}
}

Widget onclick not working with configuraion activity

When I click a button in a widget, a Toast appears. But when I use a configuration activit to set the button's caption and then I click the button, the Toast doesn't appear. Why?
public class MyWidget extends AppWidgetProvider {
public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget";
public static String ACTION_WIDGET_RECEIVER = "ActionReceiverWidget";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
Intent intent = new Intent(context, MyWidget.class);
intent.setAction(ACTION_WIDGET_RECEIVER);
PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
remoteViews.setOnClickPendingIntent(R.id.btn_widget, actionPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews); //update our widget
}
#Override
public void onDeleted(Context context, int[] appWidgetIds) {
super.onDeleted(context, appWidgetIds);
}
#Override
public void onDisabled(Context context) {
super.onDisabled(context);
}
#Override
public void onEnabled(Context context) {
super.onEnabled(context);
}
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_WIDGET_RECEIVER))
{
Toast.makeText(context, "You have just clicked the button!", Toast.LENGTH_LONG).show();
}
super.onReceive(context, intent);
}
Appwidget-provider xml:
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider

</receiver>
Configuration Activity:
public class ConfigActivity extends Activity {
Button btn;
EditText et;
Context c;
AppWidgetManager awm;
int awID;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.config);
btn = (Button)findViewById(R.id.btn);
et = (EditText)findViewById(R.id.et);
c = ConfigActivity.this;
//Getting info about the widget that launched this Activity
Intent i = getIntent();
Bundle extras = i.getExtras();
if (extras != null)
{
awID = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
}
else
{
finish();
}
awm = AppWidgetManager.getInstance(c);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String newcaption = et.getText().toString();
RemoteViews views = new RemoteViews(c.getPackageName(), R.layout.widget_layout);
views.setTextViewText(R.id.btn_widget, newcaption);
views.setTextColor(R.id.btn_widget, Color.RED);
awm.updateAppWidget(awID, views);
Intent result = new Intent();
result.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, awID);
setResult(RESULT_OK, result);
finish();
}
});
}
}
If I remove the line android:configure="com.bfarago.tutorials.widget.ConfigActivity" from the appwidgetprovider xml, I see the Toast.

Your configure Activity's onClick calls updateAppWidget without having called setOnClickPendingIntent on the RemoteViews it passes in, so once it has run, there will be no click event from your widget. Fix it to be the same as your onUpdate method, or better yet, refactor the code so there's only one function that creates the RemoteViews and calls updateAppWidget.

update textView in a widget

I've read a lot of Q&As but I couldn't find my answer.
May be something in my implementation is wrong.
The problem is that my TextView in the widget doesn't get updated.
The logic is this:
1.setOnClickPendingIntent on a specific button in the onUpdate()
2.clicking on this button will broadcast an intent with a declared action
3.at last i'll update the text of the textView in the onRecieve()
Widget2.class :
public class Widget2 extends AppWidgetProvider {
private static final String SCROLL_LEFT = "widget2.SCROLL_LEFT";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
for (int i = 0; i < appWidgetIds.length; i++) {
int appWidgetId = appWidgetIds[i];
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.small);
Intent scrollLeft = new Intent(Widget2.SCROLL_LEFT);
PendingIntent leftScrollPendingIntent = PendingIntent.getBroadcast(context,
appWidgetId, scrollLeft, appWidgetId);
remoteViews.setOnClickPendingIntent(R.id.left_scroller, leftScrollPendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
}
}
#Override
public void onReceive(Context context, Intent intent) {
Log.e(getClass().getSimpleName(), "onReceive()");
int appWidgetId = intent.getFlags();
if (intent.getAction().equals(SCROLL_LEFT)) {
updateCurrentWidget(context, appWidgetId);
Log.i("onReceive", SCROLL_LEFT + " appWidgetId = " + appWidgetId);
}
super.onReceive(context,intent);
}
private void updateCurrentWidget(Context context, int appWidgetId) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.small);
remoteViews.setString(R.id.name_of_the_app, "setText", "android os");
remoteViews.setTextViewText(R.id.description, "best ever");
Log.i("updateCurrentWidget", "the text have been set");
AppWidgetManager manager = AppWidgetManager.getInstance(context);
manager.updateAppWidget(appWidgetId, remoteViews);
}
manifest.xml :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="4"
android:targetSdkVersion="14" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<receiver android:name=".Widget2" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="widget2.SCROLL_LEFT" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/widget_small" />
</receiver>
</application>
</manifest>
and here is the simplified logcat logs:
onReceive()
"myPackageName".Widget2.SCROLL_LEFT
the text have been set
"myPackageName".Widget2.SCROLL_LEFT appWidgetId = 268435456
everything seems to be correct but the text is never changed!

The key in the widget is you have to set every View and every Intent before calling the updateAppWidget() method. Here You can call updateWidgetInstance(...) from your onReceive() method:
// action = the String that you get from your intent in the onRecive() method
// id = the id of the appWidget instance that you want to update
// you can get the id in the onReceive() method like this:
// int id = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
private static void updateWidgetInstance(Context context, AppWidgetManager manager, String action, int id) {
RemoteViews remoteViews = updateCurrentWidget(context, id);
remoteViews = setIntents(remoteViews, context, id);
manager.updateAppWidget(id, remoteViews);
}
updating the View: (Here you can also change the layout of this instance depending on your needs)
private static RemoteViews updateCurrentWidget(Context context, int appWidgetId) {
RemoteViews remoteViews;
remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_small_layout);
remoteViews.setTextViewText(R.id.widget_name_of_the_app, "Android OS");
remoteViews.setTextViewText(R.id.widget_app_description, "best ever");
remoteViews.setImageViewUri(R.id.widget_icon_of_the_app, ...);
return remoteViews;
}
updating intents:
private static RemoteViews setIntents(RemoteViews rm, Context context, int appWidgetId) {
Intent click = new Intent(context, Widget.class);
click.setAction("[name of the action]");
click.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent pendingIntent =
PendingIntent.getBroadcast(context, appWidgetId, click, PendingIntent.FLAG_UPDATE_CURRENT);
rm.setOnClickPendingIntent(R.id.button1, pendingIntent);
return rm;
}

you are setting your appWidgetId in the PendingIntent flags. that's just wrong since PendingIntet flags have meanings, they are not meant to save some data.
You should use the extras for that.

Android widget, start intent

I'm trying to make an Android widget, to show some info from my app.
I have succeed to show some info, but know i what to have a feature to "switch page" in my app. It means pressing a button, and new info is showing. But how do i do it? I have tried different thing, and I'm ending up with the following code:
public class HelloWidget extends AppWidgetProvider {
RemoteViews remoteViews;
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
Toast.makeText(context, "onUpdate", Toast.LENGTH_SHORT).show();
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
Intent intent = new Intent();
intent.setAction(TestReceiver.TEST_INTENT);
intent.setClassName(TestReceiver.class.getPackage().getName(), TestReceiver.class.getName());
PendingIntent pendingIntent = PendingIntent.getBroadcast(context.getApplicationContext(), 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.bbutton1, pendingIntent);
remoteViews.setTextViewText(R.id.widgetTxt, "The textview");
appWidgetManager.updateAppWidget(appWidgetIds[0], remoteViews);
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
public class TestReceiver extends BroadcastReceiver {
public static final String TEST_INTENT = "MyTestIntent";
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "You reached the TestReceiver", Toast.LENGTH_SHORT).show();
if (intent.getAction() == TEST_INTENT) {
remoteViews.setTextViewText(R.id.widgetTxt, "Is changed");
}
}
}
#Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
final int appWidgetId = intent.getExtras().getInt(
AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
this.onDeleted(context, new int[] { appWidgetId });
}
} else {
super.onReceive(context, intent);
}
}
#Override
public void onDeleted(Context context, int[] appWidgetIds) {
Toast.makeText(context, "onDelete", Toast.LENGTH_SHORT).show();
super.onDeleted(context, appWidgetIds);
}
}
Toast are showing "onUpdate" and then i remove it at "onDeleted". The textview also change in the onUpdate, but nothing happens when i press the button.
My Manifest look like this:
<receiver android:name=".HelloWidget" 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/hello_widget_provider" />
</receiver>
<receiver android:name=".TestReceiver" android:label="#string/app_name">
<intent-filter>
<action android:name="MyTestIntent">
</action>
</intent-filter>
</receiver>
What am i doing wrong?
Thanks

Is your TestReceiver an inner class of HelloWidget?
Then you didn't specify the correct name in the manifest.
