I am making an Android application to lock applications.
I have selected the applications I want to lock and saved them in SharedPreferences, but I don't know how to make the service which will detect every application which will be launched on the mobile and compare that package name with the package names saved in SharedPreferences and display my lock activity instead of that application.
This is the code I have written in my service.
public class DetectorService extends Service {
#Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
String foregroundTaskPackageName;
RunningTaskInfo foregroundTaskInfo;
try {
Thread.sleep(100);
ActivityManager am = (ActivityManager) getBaseContext().getSystemService(ACTIVITY_SERVICE);
foregroundTaskInfo = am.getRunningTasks(1).get(0);
foregroundTaskPackageName = foregroundTaskInfo.topActivity.getPackageName();
PackageManager pm = getBaseContext().getPackageManager();
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
return;
}
String[] abc = AppLockerPreference.getInstance(getApplicationContext()).getApplicationList();
for(int i = 0 ; i < abc.length ; i++)
{
if(abc[i].equals(foregroundTaskInfo.topActivity.getPackageName().toString()))
{
Intent lockIntent = new Intent(getApplicationContext(), GalleryImages.class);
lockIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplicationContext().startActivity(lockIntent);
}
}
}
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
}
And this is my code where I select the applications and save them in SharedPreferences. I am starting the service onPause method of this code.
public class AllAppsActivity extends ListActivity {
private PackageManager packageManager = null;
private List<ApplicationInfo> applist = null;
private ApplicationAdapter listadaptor = null;

New Activity UI load but does not respond, After running onStop() which trigger submit()
List View with the checkbox is bound by a custom adapter. On touch of the Submit button, an intent is triggered which takes me to HomeActivity and onStop() method is triggered which in return call submit method. All submit method is created under a new thread which interfere with UI.

Android's AsyncTask class will help you. Do the bluetooth discovery task in the doInBackground() method of AsyncTask.You can Toast a message a after the task in the onPostExecute() method. Here is sample code snippet to demonstrate the use of AsyncTask
I have this problem. I need to send a call to my SAX Parser (every time user tries enter name of the student) to get the names. What I am doing right now is sending a token-string to my HttpHandler which is returning 10 records every time because total no of students are about 40K so I can't parse them all at once. I am calling my AsyncTask for ParsingXML in onTextChanged event of AutoCompletetextview. but still I am not able to set the adapter to Autocomplete.
public ArrayList<AutoCompleteUserDataGetterSetter> parsexml(String token)
{
try {
SAXParserFactory saxPF = SAXParserFactory.newInstance();
SAXParser saxP = saxPF.newSAXParser();
XMLReader xmlR = saxP.getXMLReader();
URL url = new URL(xyz.com/xyz.ashx?token=+"token"); // URL of the XML
AutoCompleteUserDataXMLHandler myXMLHandler = new AutoCompleteUserDataXMLHandler();
xmlR.setContentHandler(myXMLHandler);
xmlR.parse(new InputSource(url.openStream()));
} catch (Exception e) {
System.out.println(e);
}
return data=AutoCompleteUserDataXMLHandler.getArrayData();
}
Here is my AutoCompleteTextViewAdapter Code
ArrayList<AutoCompleteUserDataGetterSetter> data=new ArrayList<AutoCompleteUserDataGetterSetter>();
public UserNewMessageAutoCompleteAdapater(Context context,
int textViewResourceId,
ArrayList<AutoCompleteUserDataGetterSetter>data) {
super(context, textViewResourceId, data);
// TODO Auto-generated constructor stub
this.context = context;
this.data=data;
vi = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
final AutoCompleteUserDataGetterSetter i = this.data.get(position);
if (i != null) {
Log.d("adapter", "in here");
AutoCompleteUserDataGetterSetter si = (AutoCompleteUserDataGetterSetter) i;
v = vi.inflate(R.layout.autocompletetext_layout, null);
final TextView title = (TextView) v
.findViewById(R.id.autocomplete_name);
TextView userid = (TextView) v
.findViewById(R.id.autocompleteuserid);
if (title != null)
title.setText(si.GetFullName());
userid.setText(si.GetUserId());
}
return v;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return data.size();
}
#Override
public AutoCompleteUserDataGetterSetter getItem(int arg0) {
// TODO Auto-generated method stub
return data.get(arg0);
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
and here is my AsyncTask Class
class SomeTask extends AsyncTask<Void, Void, Void> {
private final ProgressDialog dialog = new ProgressDialog(UserMessagesComposeNewActivity.this);
#Override
protected void onPreExecute() {
}
#Override
protected Void doInBackground(Void... voids) {
UserMessagesComposeNewActivity.this.data=parsexml(users.getText().toString());
for(int i=0;i<data.size();i++)
{
nameadapter.add(data.get(i).GetFullName());
useridadapter.add(data.get(i).GetUserId());
}
if(data==null)
{
AutoCompleteUserDataGetterSetter umsgs=new AutoCompleteUserDataGetterSetter();
umsgs.SetFullName(" ");
umsgs.SetUserID("");
data.add(umsgs);
}
return null;
}
#Override
protected void onPostExecute(Void aVoid) {
if (this.dialog.isShowing()) {
this.dialog.dismiss();
}
users.setAdapter(nameadapter);
}
}
