[Q] How do you make a clock widget open Alarm Clock App?

Okay, so i asked this question a while back and didnt get much help, but I am extremely lost. My partner who before actually programmed the app put in the necessary stuff, however i dont think it works in froyo+. I am extremely new to programming in general, and i cannot for the life of me figure this out. I have even tried other codes, but they dont work. Can someone please give me a detailed description on how to make a clock widget open the alarm clock app.
BTW this is the code that we are using at the moment:
package honeycomb.clocks;
import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;
public class BlueClock 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.blueclock);
Intent ClocksIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER).setComponent(new ComponentName("com.android.alarmclock", "com.android.alarmclock.AlarmClock"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, ClocksIntent, 0);
views.setOnClickPendingIntent(R.id.Widget, pendingIntent);
AppWidgetManager.getInstance(context).updateAppWidget(intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS), views);
}
}
}

Hi,
I don't know if there's a better aproach, but this is the actual code I'm using to launch the alarm:
Code:
public static final Intent alarmIntent(Context context) {
PackageManager packageManager = context.getPackageManager();
Intent alarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER);
// Verify clock implementation
String clockImpls[][] = {
{"HTC Alarm ClockDT", "com.htc.android.worldclock", "com.htc.android.worldclock.WorldClockTabControl" },
{"Standar Alarm ClockDT", "com.android.deskclock", "com.android.deskclock.AlarmClock"},
{"Froyo Nexus Alarm ClockDT", "com.google.android.deskclock", "com.android.deskclock.DeskClock"},
{"Moto Blur Alarm ClockDT", "com.motorola.blur.alarmclock", "com.motorola.blur.alarmclock.AlarmClock"},
{"Samsung Galaxy S", "com.sec.android.app.clockpackage","com.sec.android.app.clockpackage.ClockPackage"}
};
boolean foundClockImpl = false;
for(int i=0; i<clockImpls.length; i++) {
String packageName = clockImpls[i][1];
String className = clockImpls[i][2];
try {
ComponentName cn = new ComponentName(packageName, className);
packageManager.getActivityInfo(cn, PackageManager.GET_META_DATA);
alarmClockIntent.setComponent(cn);
foundClockImpl = true;
} catch (NameNotFoundException nf) {
}
}
if (foundClockImpl)
return alarmClockIntent;
else
return null;
}
Hope it helps!

Unfortunately it didnt help me , Im not a programmer, and I dont know what Im supposed to do with this code and my partner is pissing me off

in order to launch an external activity from an appwidget you need to set a very specific flag on the intent you broadcast. mine was for launching gmail.
Code:
Intent mailClient = new Intent(Intent.ACTION_VIEW);
mailClient.setClassName("com.google.android.gm", "com.google.android.gm.ConversationListActivity");
[B]mailClient.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);[/B]
PendingIntent onClickPending = PendingIntent.getBroadcast(context, 0, mailClient, 0);
RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.gitc_widget_html);
rv.setOnClickPendingIntent(R.id.full_widget, onClickPending);
//then update Your Appwidgets
//AppWidgetManager manager = AppWidgetManager.getInstance(context);
//manager.updateAppWidget(mAppWidgetId, rv);
and please realize that this was kinda a stub of what to do. i left alot out that was specific to my appwidget but that was needed for this to work. but the premise of creating an intent for what you want to launch then creating a pendingIntent and then attaching it to a view of your appwidget and then updating the remote view of you appwidget by using an AppwidgetManager holds true for any situation.
if you need me to elaborate then we can chat then.
-----
o and you aren't updating your appwidgets properly...
you need to get an array of all appwidgets you have and then call updateAppWidget on each like this (again, with my class names and such)
Code:
AppWidgetManager manager = AppWidgetManager.getInstance(context);
int[] ids = manager.getAppWidgetIds(new ComponentName(context, GITextCloud.class));
for (int id : ids) {
manager.updateAppWidget(id, rv);
//rv is the RemoteViews you created earlier up in the program...
//RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.gitc_widget_html);
}

this isnt actually launching the clock application. you are just returning an intent that can be used to launch the clock application (still need to make a pendingIntent and attach it to a view). there is a difference and a new programmer could be very confused by this post.
other than that it looks like a nice way to find the class and package names for what clock is installed. =)

Here is the Complete Source of my Appwidget Provider it generates a Clickevent on Appwidget to start the specific alarm app on the different phones.
Here is the Link to the simple Clock widget i have extended
Hope this helps!!

SUCCESS!!!!! Thank you guys so much, you have no idea how grateful I am for your help.

ImageView from url in listview

i created a java web service. it returns ArrayList type(text,image URL).
and my client side code i receive the by following code:
public class CustomeAdapter extends ArrayAdapter<RowItem> {
private List<RowItem> objects;
Context context;
private Bitmap bitmap;
Drawable d;
ViewHolder holder = null;
public CustomeAdapter(Context context, int listViewResourceId, List<RowItem> first) {
super(context, listViewResourceId, first);
this.context = context;
}
private class ViewHolder {
ImageView image;
TextView name,service,local;
}
@suppressLint("NewApi")
public View getView(int position, View convertView, ViewGroup parent){
//ViewHolder holder = null;
RowItem rowItem = getItem(position);
//final Bitmap bitmap = null;
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {

try {
URL url = new URL(src);
bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());
holder.image.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
return convertView;
}
i am getting followimg error:
android.os.NetworkOnMainThreadException
can any one help me

I think there is a library that does this well, but can't remember it right now...
Check the library repo, and some of the apps that list libraries. Also, maybe Google will turn up something helpful.

Lazy list perhaps?

Loading a new fragment from an OnClick set in asyncTask

I have a fragment, which contains a button that when pressed loads a new fragment. The new fragment runs an async task to populate a listview with data.
I am running into trouble, trying to load a new fragment from the onClick. The problem is I can not get the getFragmentManager();
My async task looks like this:
Code:
public class GetStyleStatisticsJSON extends AsyncTask<String, Void, String> {
Context c;
private ProgressDialog Dialog;
android.support.v4.app.Fragment Fragment_one;
public GetStyleStatisticsJSON(Context context)
{
c = context;
Dialog = new ProgressDialog(c);
}
@Override
protected String doInBackground(String... arg0) {
// TODO Auto-generated method stub
return readJSONFeed(arg0[0]);
}
protected void onPreExecute() {
Dialog.setMessage("Analyzing Statistics");
Dialog.setTitle("Loading");
Dialog.setCancelable(false);
Dialog.show();
}
protected void onPostExecute(String result){
//decode json here
try{
JSONArray jsonArray = new JSONArray(result);
//acces listview
ListView lv = (ListView) ((Activity) c).findViewById(R.id.yourStyleStatistics);
//make array list for beer
final List<StyleInfo> tasteList = new ArrayList<StyleInfo>();
for(int i = 0; i < jsonArray.length(); i++) {
String style = jsonArray.getJSONObject(i).getString("style");
String rate = jsonArray.getJSONObject(i).getString("rate");
String beerID = jsonArray.getJSONObject(i).getString("id");
int count = i + 1;
style = count + ". " + style;
//create object
StyleInfo tempTaste = new StyleInfo(style, rate, beerID);
//add to arraylist
tasteList.add(tempTaste);
//add items to listview
StyleInfoAdapter adapter1 = new StyleInfoAdapter(c ,R.layout.brewer_stats_listview, tasteList);
lv.setAdapter(adapter1);
//set up clicks
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
StyleInfo o=(StyleInfo)arg0.getItemAtPosition(arg2);
String bID = o.id;
//todo: add onclick for fragment to load
FragmentManager man= (Activity)c.getFragmentManager();
FragmentTransaction tran = man.beginTransaction();
Fragment_one = new StylePage2();
final Bundle bundle = new Bundle();
bundle.putString("beerIDSent", bID);
Fragment_one.setArguments(bundle);
tran.replace(R.id.main, Fragment_one);//tran.
tran.addToBackStack(null);
tran.commit();
}
});
}
}
catch(Exception e){
}
Dialog.dismiss();
}

}
return stringBuilder.toString();
}
}
can not resolve method FragmentManager() is the error I am receiving

Hi,
To be able to call getFragmentManager() or getSupportFragmentManager() you'll need to use FragmentActivity, so what I would do is:
1. Make sure the activity that calls the asycTask is a FragmentActivity.
2. Pass this actvity to the asycTask.
Something like: (asyncTask method)
setActivity(Activity activity)
{
fm = activity.getFragmentManager();
}

thats the problem, I launch the asyncTask from a fragment....

Oh! So you'll access your activity like this:
getActivity().getFragmentManager();

FC when using interface to launch new fragment form listView

I have an async task that loads a list view of items. I am currently trying to set the onClick to load a new fragment with an "id" that is being retrieved from the list item that is clicked. I have no errors in my code that the Android Studio shows me.
When I run the app and click on the item in the list view I get this FC:

String userName = prefs.getString("userName", null);
String userID = prefs.getString("userID", null);
//todo: code body goes here
// Inflate the layout for this fragment
return v;
}
@override

//todo: get json
new ReadJSONResult(getActivity()).execute(jsonUrl);
return false;

Let me know if you need any other code, I am stomped on this and could use a second pair of eyes. Thanks.

SharedPreferences Context Issue

I have created a questionnaire in the beginning of the app in order to base a user model off the answers chosen. The values of the chosen options are stored as Shared Preferences as shown below. With the data retrieved I am then trying to tag a Google map with certain tags based on the answers chosen. The issue I am encountering is that of reading the stored Shared Preference values across the different activities, from the Question2 Activity, to that of the Map Activity (code below). Any pointers on how to solve the *context* conflict would be greatly appreciated.
Question2 Activity:
Code:
public class Question2 extends Activity{
RadioButton q2a1,q2a2,q2a3;
Button btn2;
public static final String MY_PREF = "MyPreferences";
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View v = inflater.inflate(R.layout.activity_question2, null);
return v;
}
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_question2);
q2a1 = (RadioButton) findViewById(R.id.q2a1);
q2a2 = (RadioButton) findViewById(R.id.q2a2);
q2a3 = (RadioButton) findViewById(R.id.q2a3);
btn2 = (Button) findViewById(R.id.q2_button);
btn2.setOnClickListener(new OnClickListener(){
public void onClick(View v){
SharedPreferences prefernces = getSharedPreferences(MY_PREF, 0);
SharedPreferences.Editor editor = prefernces.edit();
if (q2a1.isChecked()){
editor.putInt("answer_value2", 1);
editor.commit();
}
if (q2a2.isChecked()){
editor.putInt("answer_value2", 2);
editor.commit();
}
if (q2a3.isChecked()){
editor.putInt("answer_value2", 3);
editor.commit();
}else {
editor.putInt("answer_value2", 0);
editor.commit();
}
editor.commit();
Intent intent = new Intent(getApplicationContext(), Question3.class);
startActivity(intent);
}
});
}
}
Map Activity:
Code:
public class MapActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map);
map = ((MapFragment) getFragmentManager().findFragmentById(R.id.mapLayout)).getMap();
map.setMyLocationEnabled(true);
SharedPreferences preferences = getSharedPreferences(Question2.MY_PREF,MODE_PRIVATE);
int q1answer = preferences.getInt("answer_value", 0);
int q2answer = preferences.getInt("answer_value2", 0);
int q3answer = preferences.getInt("answer_value3", 0);
if(q1answer == 1){
//method
}
if(q1answer == 2){
//method
}
if(q1answer == 3){
//method
}
if(q2answer == 1){
map.addMarker(new MarkerOptions().position(FOOD_FOOD).title("Food & Food").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
map.addMarker(new MarkerOptions().position(HEALTHSHOP).title("Health Shop").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
map.addMarker(new MarkerOptions().position(GRASSYHOPPER).title("Grasy Hopper").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));

map.addMarker(new MarkerOptions().position(MINT).title("Mint").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
}if(q2answer == 2){
Toast.makeText(getApplicationContext(), "Your result is " + q2answer, Toast.LENGTH_SHORT).show();
map.addMarker(new MarkerOptions().position(FOOD_FOOD).title("Food & Food").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
map.addMarker(new MarkerOptions().position(SUBWAY).title("Subway").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
map.addMarker(new MarkerOptions().position(NEWYORKSBEST).title("New York's Best").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));

map.addMarker(new MarkerOptions().position(BURGERKING).title("Burger King").icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));

Use this
create this class in your package
Code:
public class SharedPrefence{
// Shared Preferences
SharedPreferences pref;
// Editor for Shared preferences
Editor editor;
// Context
Context _context;
// Shared pref mode
int PRIVATE_MODE = 0;
// Sharedpref file name
private static final String PREF_NAME = "MyPreferences";
// Answers (make variable public to access from outside)
public static final String KEY_ANSWER_TWO = "answer_value2";
//similarly other answers tag can be added(this is the key of preference)
// Constructor
public SharedPrefence(Context context) {
_context = context;
pref = _context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
editor = pref.edit();
}
/**
* Create Answer.
* */
public void createAnswer(int ans) {
// Storing name in pref
editor.putInt(KEY_ANSWER_TWO, ans);
// commit changes
editor.commit();
}
public int getAnswer(String tag,int default) {
return pref.getString(tag, default);
}
}
now create an activity and initialise this class in the starting with the activity context.
next call the create answer method of this class and you are done.
also no need to create sharedprefence in each activity.
and it's even better if you create only one activity and use ViewPager for all questions.you can google for it.
