How to create a backward compatible Android swap application widget?

I'm having trouble finding any tutorials on how to create a page widget widget, for example on Facebook, Twitter and FriendCaster.

I could use the new Android 3.0 + tools with an adapter, however it would be difficult to verify, since I have no devices, and my computer is not either.

This can be done by providing your appwidget with a state that determines the page displayed on it. And assign the broadcast to the buttons to change the state.

  • Send a broadcast when the PendingIntent buttons are pressed .
  • receiver listen to the broadcast and track the status (page)
  • Update the application depending on the current state

Here is an example of incomplete code:

RemoteViews remoteViews = new RemoteViews(mContext.getPackageName(), R.layout.widget_weather); // update appwidget remoteviews depending on state (ie which page to show) remoteViews = populateViews(remoteViews, mState); // set next button Intent intent = new Intent(MYBROADCAST_NEXT); PendingIntent pendingIntent = PendingIntent.getBroadcast(context, requestCode, intent, flags); remoteViews.setOnClickPendingIntent(R.id.appwidget_btn_next, pendingIntent); // set prev button intent = new Intent(MYBROADCAST_PREV); pendingIntent = PendingIntent.getBroadcast(context, requestCode, intent, flags); remoteView.setOnClickPendingIntent(R.id.appwidget_btn_prev, pendingIntent); // update the AppWidget ...

Hope this helps you achieve what you want.

You can use the compatibility package, it is compatible with feedback. The minimum API level is 4, this is Android 1.6
