}
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?

Adding custom apps to an app switcher panel

I am currently working on an App Switcher with the ability to also add custom apps in the app switcher. So, I already got the recent apps loader built. This is the code for this part of the app:

}
}
SharedPreferences myPreference = PreferenceManager.getDefaultSharedPreferences(this);
String itembg = myPreference.getString("itembg_list", "");
if(itembg.equals("defaults"))
{

listView.setAdapter(adapter);
}
else if(itembg.equals("dark"))

listView.setAdapter(adapter);
}
else
{

listView.setAdapter(adapter);
}
listView.setOnItemClickListener(new OnItemClickListener() {
[user=439709]@override[/user]
public void onItemClick(AdapterView<?> parent, View view, int postion, long id) {
try{
boolean rightpanel = getSharedPreferences(getPackageName() + "_preferences", Context.MODE_PRIVATE).getBoolean("panelpos_right", true);
Intent taskintent = getPackageManager().getLaunchIntentForPackage(packageName.get(postion).toString());
startActivity(taskintent);
if(rightpanel){
overridePendingTransition(R.anim.right_slide_in, R.anim.zoom_out);
}
else
{
overridePendingTransition(R.anim.left_slide_in, R.anim.zoom_out);
}
finish();
}
catch (NullPointerException fail) {
Toast.makeText(getApplicationContext(), "!", Toast.LENGTH_SHORT).show();
}
}
});
SharedPreferences panelbgpref = PreferenceManager.getDefaultSharedPreferences(this);
String panelbgset = panelbgpref.getString("panelbg_list", "");
if(panelbgset.equals("light"))
{
panelbg.setImageResource(R.drawable.panelbg_light);
}
else
{
panelbg.setImageResource(R.drawable.panelbg);
}
imgbtn.setOnClickListener(new View.OnClickListener(){
[user=439709]@override[/user]
public void onClick(View v) {
if(v.getId() ==R.id.transparentbackground){
moveTaskToBack(true);
finish();
}
}
});
}
Now I want to let the users define in the app settings up to 3 own apps that should be shown on every moment.
How should I do that?
Thank you

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();
}
public String readJSONFeed(String URL) {

HttpGet httpGet = new HttpGet(URL);
try {

}
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();
}

Click to expand...
Click to collapse
thats the problem, I launch the asyncTask from a fragment....

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

How do I implement a onscroll Listener to my listview?

I have a large data to load from JSON.
I have implemented a custom list view by following a tutorial, now since the data is huge I want it load as the user scrolls.
This is my LoadRestaurant class code which is inside the main activity.
Code:
class LoadRestaurants extends AsyncTask<String, String, String> {
//Show Progress Dialog
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(SearchAll.this);
pDialog.setMessage("Loading All Restaurants...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
protected String doInBackground(String... arg) {
//building parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
//Getting JSON from URL
String json = jsonParser.makeHttpRequest(URL_RESTAURANT_LIST, "GET", params);
//Log Cat Response Check
Log.d("Areas JSON: ", "> " + json);
try {
restaurants = new JSONArray(json);
if (restaurants != null) {
//loop through all restaurants
for (int i = 0; i < restaurants.length(); i++) {
JSONObject c = restaurants.getJSONObject(i);
//Storing each json object in the variable.
String id = c.getString(TAG_ID);
String name = c.getString(TAG_NAME);
String location = c.getString(TAG_LOCATION);
String rating = c.getString(TAG_RATING);
//Creating New Hashmap
HashMap<String, String> map = new HashMap<String, String>();
//adding each child node to Hashmap key
map.put(TAG_ID, id);
map.put(TAG_NAME, name);
map.put(TAG_LOCATION, location);
map.put(TAG_RATING, rating);
//adding HashList to ArrayList
restaurant_list.add(map);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String file_url) {
//dismiss the dialog
pDialog.dismiss();
//Updating UI from the Background Thread
runOnUiThread(new Runnable() {
@Override
public void run() {
ListAdapter adapter = new SimpleAdapter(
SearchAll.this, restaurant_list,
R.layout.listview_restaurants, new String[]{
TAG_ID, TAG_NAME, TAG_LOCATION, TAG_RATING}, new int[]{
R.id.login_id, R.id.restaurant_name, R.id.address, R.id.rating});
setListAdapter(adapter);
ListView lv = getListView();
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// Bundle bundle = new Bundle();
Intent intent = new Intent(SearchAll.this, RestaurantProfile.class);
String loginId = ((TextView) view.findViewById(R.id.login_id)).getText().toString();
intent.putExtra("login_id", loginId);
startActivity(intent);
}
});
}
});
}
}
}
I want to load around 20 restaurants and then it auto loads another 20 as soon as user reaches the end of first 20.
There are lots of tutorials online but its confusing to implement.
Please help me out!

The custom ListView, support for automatic loading you can try https://github.com/chrisbanes/Android-PullToRefresh

[Q] Create notification when bluetooth data is received in the background

I am currently working on an arduino project that connects to my phone using a bluetooth module.
On the arduino I have various diagnostic sensors hooked up to it. When the sensors "sense an error," I would like to receive a notification on my phone.
I'm guessing this would require me to program an app that runs as a background service listening for data coming across the bluetooth connection. Then when it receives the data it would need to create a notification and play the system notification sound.
Is it even possible to listen to the data coming from the bluetooth module while being run in the background?
How hard would this be for me, a beginner, to program? I have programmed in several other languages (html, visual basic, and python), so I understand basic coding concepts.

I would like to thank everyone for all the help. The amount of replies just shows how useful this forum is to beginning devs.
Anyways, after three days of straight research, I pumped out a working app. Now I would like for someone to review my code and see if anything can be revised or done better, as I really don't know what I'm doing.
