Hey,
I'm doing a task that, in my opinion should be relatively simple. I have an
application on android, and I want to make a widget that, when clicked on,
launches the application. I've followed many forum posts online, and yet
have come up short. I would really appreciate any insight into the issue.
Thanks in advance. The following are the details of my widget:
*My Widget Class:*
package com.followup;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;
public class IconWidgetProvider extends AppWidgetProvider {
@Override
public void onUpdate(final Context context, final AppWidgetManager
appWidgetManager, final int[] appWidgetIds) {
final int N = appWidgetIds.length;
for (int i=0; i<N; i++) {
final int appWidgetId = appWidgetIds[i];
final Intent intent = new Intent(context, FollowUpActivity.class);
//FollowUpActivity.class is the class of the main app
final PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);
final RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.icon_widget_layout);
views.setOnClickPendingIntent(R.id.image_in_widget, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
}
