Change an Android intent action from opening URI to displaying a toast? - android

I'm trying to have my widget use an onClick action to prompt a refresh. I found some demo code that works, but it opens a URI in browser. I'm having trouble replacing the URI action with something simpler, like displaying a toast. I've marked the line that I'm trying to change, but I don't know how to make Android set a different action other than Action.VIEW.
public class NewAppWidget extends AppWidgetProvider {
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
//I AM TRYING TO CHANGE THIS INTENT
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://google.com/"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
views.setOnClickPendingIntent(R.id.refresh, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
#Override //Nothing changed here
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
}
}
The specific lines are
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://google.com/"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

I got this to work completely unexpectedly. I followed this post but left my intent declarations where they were. The resulting lines were:
Intent intent = new Intent(context, NewAppWidget.class);
intent.setAction(refresh);
intent.putExtra("appWidgetId", appWidgetId);
views.setOnClickPendingIntent(R.id.refresh, PendingIntent.getBroadcast(context,0,intent, PendingIntent.FLAG_UPDATE_CURRENT));
appWidgetManager.updateAppWidget(appWidgetId, views);
followed by onReceive:
#Override
public void onReceive(Context context, Intent intent) {
if(refresh.equals(intent.getAction())) {
Toast.makeText(context, "Clicked", Toast.LENGTH_LONG).show();
}
}
Edit for clarity: intent.getAction() needs to be a registered action within the receiver's intent filter.

appWidgetIds only contain one id

I have appWidgetProvider that updates views of each widget located on homescreen and each widget has a button which triggers updating the view but apparently no matter which button I press on whichever widget only and always the one of them is being updated
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
for (int widgetId: appWidgetIds){
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget);
Intent update = new Intent(context, QuotesAppWidgetProvider.class);
Bundle bundle = new Bundle();
bundle.putIntArray(AppWidgetManager.EXTRA_APPWIDGET_IDS, new int[]{widgetId});
update.putExtras(bundle);
update.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, update, 0);
views.setOnClickPendingIntent(R.id.widget_refresh, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, views);
}
}
Let's say I have widget with id=30 and widget with id=31 and I click the refresh button on widget30 and then widget30 is being updated which is desired but when I click on refresh button on widget31 then widget30 is being updated for I don't know what reason.
It took me a bit but I finally figured it out. All of the widgets had pendingintents with the same request code and since it was broadcast it overwritten all of them with one. This was the line that helped me:
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, widgetId, update, PendingIntent.FLAG_UPDATE_CURRENT);
Use this code and check.
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
for (int widgetId: appWidgetIds){
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget);
Intent update = new Intent(context, getClass());
update.setAction("actUpdateWidgets");
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, update, 0);
views.setOnClickPendingIntent(R.id.widget_refresh, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, views);
}
}
#Override
public void onReceive(Context context, Intent intent)
{
super.onReceive(context, intent);
if (intent.getAction().equalsIgnoreCase("actUpdateWidgets"))
{
Intent i = new Intent(context, QuotesAppWidgetProvider.class);
i.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
int ids[] = AppWidgetManager.getInstance(context).getAppWidgetIds(new ComponentName(context, QuotesAppWidgetProvider.class));
i.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, ids);
context.sendBroadcast(i);
}
}

How to launch an activity after clicking a widget?

I want to create a simple widget with an icon to launch my app.
I have the widget and its layout working properly, but I can't find the way to make it launcher the app when clicking it.
This is the widget class:
public class LauncherWidget extends AppWidgetProvider {
private static final String ACTION_CLICK = "ACTION_CLICK";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager) {
Intent intent = new Intent(context, SplashActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Attach the intent to the widget's button.
final PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
remoteViews.setOnClickPendingIntent(R.id.widget, pendingIntent);
}
}
I have never created a widget so I have no idea what to do here.
I have checked round here for more info but all I can find are widgets that update its content when clicking, but I tried to use their code but it isn't working.
Thanks in advance.
This is what worked for me...
The onUpdate method code should be:
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int i = 0; i < appWidgetIds.length; i++) {
int appWidgetId = appWidgetIds[i];
try {
Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
intent.setComponent(new ComponentName(context.getPackageName(),
"Activity.class"));
PendingIntent pendingIntent = PendingIntent.getActivity(
context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.widget_layout);
views.setOnClickPendingIntent(R.id.widget, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
} catch (ActivityNotFoundException e) {
Toast.makeText(context.getApplicationContext(),
"There was a problem loading the application: ",
Toast.LENGTH_SHORT).show();
}
}
}
Use this snippet in onUpdate() method of your widget AppWidgetProvider class:
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widgetlayout);
Intent configIntent = new Intent(context, Activity.class);
PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0);
remoteViews.setOnClickPendingIntent(R.id.widget, configPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}

Settings Activity Not Launching

So far i have coded:
public class WidgetActivity extends AppWidgetProvider
{
public void onReceive(Context context, Intent intent)
{
String action = intent.getAction();
if (AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action))
{
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_activity);
Intent settingsIntent = new Intent(context, Info.class);
PendingIntent clickPendIntent = PendingIntent.getActivity
(context, 0, settingsIntent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.Widget, clickPendIntent);
AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);
}
}
}
To no success i click the widget when its on screen and nothing launches. Am I missing anything?
Put the code that makes sure the PendingIntent is set, in the onUpdate() method instead. This makes sure that as soon as the widget is put on the homescreen that the PendingIntent is set.
So:
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgets) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_activity);
Intent intent = new Intent(context, Info.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
remoteViews.setOnClickPendingIntent(R.id.Widget, pendingIntent);
Also:
If you would also like to have the info Activity pop up automatically when first adding the widget to the home screen, you should read this userful piece of information.

Android Widget: OnClickPendingIntent won't Work

Why doesn't recieve get called when I click on Button wid??
Code:
public class Widget extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int i = 0; i < appWidgetIds.length; i++) {
int appWidgetId = appWidgetIds[i];
Intent intent = new Intent(context, Widget.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
views.setOnClickPendingIntent(R.id.wid, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
Log.d("ARH","CLICKK");
}
Becuase I need a button to manual refresh the widget but it seems that Log.d("ARH","CLICKK"); only gets called when i add the Widget.
Thanks!
You using a PendingIntent to call an Activity but your Widget class is not an activity.
If you want to update to your widget, then you need to use getBroadcast that sends an APPWIDGET_UPDATE action.

Android simple widget that launches activity

Hi i've never worked with widgets before but what i'm looking to do is create a very simple widget i basically want to make a 1 by 1 widget that has just an icon, just an image set as the background no text nothing just a small icon and when the icon is pressed i want to open an activity. Basically i want to make a second icon like in the app drawer in a widget form that opens another activity rather than the main one.
Any help is greatly appreciated
My provider ended up looking like this after a lot of research and playing
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, ClassToLaunchHere.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
views.setOnClickPendingIntent(R.id.widget, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
}
Couple of app widget implementations that show the easiest way to do that are visible at https://github.com/commonsguy/cw-advandroid/tree/master/AppWidget.
Specifically, https://github.com/commonsguy/cw-advandroid/blob/master/AppWidget/PairOfDice/src/com/commonsware/android/appwidget/dice/AppWidget.java shows how to use a PendingIntent as the onClick target for a Button. You can make your PendingIntent start an Activity and you should be good to go.
Declare a Variable
public static String YOUR_AWESOME_ACTION = "YourAwesomeAction";
then add onUpdate and onReceive
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
ComponentName thisWidget = new ComponentName(context, DigitalClock.class);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.digital_clock);
for (int widgetId : appWidgetManager.getAppWidgetIds(thisWidget)) {
remoteViews.setOnClickPendingIntent(R.id.imageView, getPendingSelfIntent(context, YOUR_AWESOME_ACTION));
appWidgetManager.updateAppWidget(thisWidget, remoteViews);
}
}
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
super.onReceive(context, intent);
if (YOUR_AWESOME_ACTION.equals(intent.getAction())) {
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.digital_clock);
ComponentName watchWidget = new ComponentName(context, DigitalClock.class);
appWidgetManager.updateAppWidget(watchWidget, remoteViews);
Intent ntent = new Intent(context, MainActivity.class);
ntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(ntent);
//Toast.makeText(context, YOUR_AWESOME_ACTION, Toast.LENGTH_SHORT).show();
}
}
protected PendingIntent getPendingSelfIntent(Context context, String action) {
Intent intent = new Intent(context, getClass());
intent.setAction(action);
return PendingIntent.getBroadcast(context, 0, intent, 0);
}
and add activity on Manifest
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
hope this will help
