I see now, the method i would like to use in 1.5 is setPackage not
setComponent; sorry for the misunderstanding.
I don't want to use setComponent because i don't know the classname to use
(and i don't want to hardcode it as i guess it might change as it is an
external application). And setPackage is only available since API level 4 :(
I have used your Launchalot exemples to dynamically retrieve the classname.
Here is what i did that seems to work:
String packageName = "com.foo.blabla";
Intent mainApps = new Intent(Intent.ACTION_MAIN);
mainApps.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> activities =
act.getPackageManager().queryIntentActivities(mainApps, 0);
Iterator<ResolveInfo> it = activities.iterator();
while (it.hasNext()) {
ResolveInfo info = it.next();
ActivityInfo activity=info.activityInfo;
if (activity.packageName.equalsIgnoreCase(packageName )) {
Intent intent=new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
ComponentName name = new
ComponentName(activity.packageName, activity.name);
intent.setComponent(name);
act.startActivity(intent);
return true;
}
}
// handle not found case
Any shorter and faster way (and compatible with 1.5) to do it is welcome :)
