My Soundboard force closes every now and again

I have a problem: Everytime I click a button on my soundboard it has a 50/50 chance of force closing. the only thing I can think of is something in this line of code maybe:
Code:
public class MyMain extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//set up the button sounds
final MediaPlayer mpButtonClick = MediaPlayer.create(this, R.raw.money);
Button bmoney = (Button) findViewById(R.id.money);
bmoney.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
mpButtonClick.start();
}
});
final MediaPlayer pButtonClick = MediaPlayer.create(this, R.raw.pants);
Button bpants = (Button) findViewById(R.id.pants);
bpants.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
pButtonClick.start();
}
});

...If you wish to later replay the media, then you must reset() and prepare() the MediaPlayer object before calling start() again. (create() calls prepare() the first time.)....
Click to expand...
Click to collapse
Thats probably the problem.

[Q] Schedule with long delay

Hello guys. I'm making an app, its a kind of alarm scheduler but I have a problem with the code. Thats what im using
Code:
ScheduledThreadPoolExecutor scheduler=new ScheduledThreadPoolExecutor(1);
scheduler.schedule(new Runnable() {
public void run(){
alarm(1);
} }, delay , TimeUnit.SECONDS);
It works for low values of "delay" if I put a high value (11000 for example) and leave the device alone, I think it enters in sleep mode and dont execute the timer.
How can I solve that?
Thanks in advance

I dont know about the scheduler but an alarm manager can wake the phone from sleep if you want. Or run the alarm in the background while asleep
From something awesome

Thanks for your answer, worked for me.
Here's the code, it maybe help others

Passing data between two fragments

Hello guys,
I have a list of fragments created and I want to delete these fragment by long pressing on them. However, before doing so I want dialog fragment to pop up and offer the user the choice to delete or not. I have created the two fragments but I can't get the data across each other. I can't give functionality to the 'OK' button. Here is my code:
Code:
public class CourseListFragment extends Fragment implements
OnItemClickListener, OnItemLongClickListener {
public static final String ARG_ITEM_ID = "course_list";
public static final String YES_NO = "modify";
Activity activity;
ListView courseListView;
ArrayList<Course> courses;
CourseListAdapter courseListAdapter;
CourseDAO courseDAO;
private GetEmpTask task;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
activity = getActivity();
courseDAO = new CourseDAO(activity);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.schedule_fragment_course_list,
container, false);
findViewsById(view);
task = new GetEmpTask(activity);
task.execute((Void) null);
courseListView.setOnItemClickListener(this);
courseListView.setOnItemLongClickListener(this);
return view;
}
private void findViewsById(View view) {
courseListView = (ListView) view.findViewById(R.id.list_course);
}
@Override
public void onItemClick(AdapterView<?> list, View view, int position,
long id) {
Course course = (Course) list.getItemAtPosition(position);
if (course != null) {
Bundle arguments = new Bundle();
arguments.putParcelable("selectedCourse", course);
CustomCourseDialogFragment customEmpDialogFragment = new CustomCourseDialogFragment();
customEmpDialogFragment.setArguments(arguments);
customEmpDialogFragment.show(getFragmentManager(),
CustomCourseDialogFragment.ARG_ITEM_ID);
}
}
@Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {
// Show dialogFragment
FragmentManager fm = getActivity().getSupportFragmentManager();
CheckDialogFragment dialog = new CheckDialogFragment();
dialog.show(fm, YES_NO);
Course employee = (Course) parent.getItemAtPosition(position);
// Use AsyncTask to delete from database
courseDAO.deleteEmployee(employee);
courseListAdapter.remove(employee);
return true;
}
public class GetEmpTask extends AsyncTask<Void, Void, ArrayList<Course>> {
private final WeakReference<Activity> activityWeakRef;
public GetEmpTask(Activity context) {
this.activityWeakRef = new WeakReference<Activity>(context);
}
@Override
protected ArrayList<Course> doInBackground(Void... arg0) {
ArrayList<Course> courseList = courseDAO.getCourses();
return courseList;
}
@Override
protected void onPostExecute(ArrayList<Course> empList) {
if (activityWeakRef.get() != null
&& !activityWeakRef.get().isFinishing()) {
courses = empList;
if (empList != null) {
if (empList.size() != 0) {
courseListAdapter = new CourseListAdapter(activity,
empList);
courseListView.setAdapter(courseListAdapter);
} else {
Toast.makeText(activity, "No Course Records",
Toast.LENGTH_LONG).show();
}
}
}
}
}
/*
* This method is invoked from MainActivity onFinishDialog() method. It is
* called from CustomEmpDialogFragment when an employee record is updated.
* This is used for communicating between fragments.
*/
public void updateView() {
task = new GetEmpTask(activity);
task.execute((Void) null);
}
@Override
public void onResume() {
getActivity().setTitle("Course Schedule");
getActivity().getActionBar().setTitle("Course Schedule");
super.onResume();
}
}
//Dialog Fragment
Code:
public class CheckDialogFragment extends DialogFragment {
CourseListAdapter courseListAdapter;
CourseDAO courseDAO;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// TODO Auto-generated method stub
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity())
.setTitle("Do you want to delete?")
.setPositiveButton(android.R.string.ok,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
}
})
.setNegativeButton(android.R.string.cancel,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
dialog.cancel();
}
});
return builder.create();
}
}
I have problems trying to get the data from onItemLongClick() of CourseListFragment to CourseListFragment. Any help would be greatly appreciated.

[Q] PreferenceFragment - problems in changing language preference

I have written the following code to allow user to display in chinese or english language. But when I select the language in the settings. There is no response and change in the App. I would like to ask if anyone could see the problems. Thank you for your help!
I have created the following folders
- values-en
- values-rTW
- values-rCN
Code:
public class AppPrefActivity extends Activity {
private SharedPreferences.OnSharedPreferenceChangeListener prefListener;
SharedPreferences pref;
public static final String PREF_LANGUAGE = "language_pref";
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
getFragmentManager().beginTransaction().replace(android.R.id.content, new PrefsFragement()).commit();
}
public static class PrefsFragement extends PreferenceFragment implements SharedPreferences.OnSharedPreferenceChangeListener{
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preference);
}
@Override
public void onResume() {
super.onResume();
getPreferenceManager().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
}
@Override
public void onPause() {
getPreferenceManager().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
super.onPause();
}
@Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
if(key.equals(PREF_LANGUAGE))
{
Preference connectionPref = findPreference(key);
connectionPref.setSummary(sharedPreferences.getString(key, ""));
changeLanguagePref(sharedPreferences.getString(key, ""));
}
}
private void changeLanguagePref(String lang){
Locale locale = null;
if (lang.equals("Traditional Chinese")){
locale = new Locale("zh_rTW");
}else if (lang.equals("Simplified Chinese")){
locale = new Locale("zh_rCN");
}else{
locale = new Locale("en");
}
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
this.getResources().updateConfiguration(config, null);
}
}
}
This is part of the xml for language selection
Code:
<PreferenceCategory android:title="@string/pref_cat_app">
<ListPreference
android:title="@string/pref_def_lang"
android:entries="@array/app_language"
android:entryValues="@array/app_language"
android:defaultValue="English"
android:key="language_pref"/>

you need to recreate the activity after you reload all the resources.
