Exception :- android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0

Creating an alarm notification and just cant figure out why i keep running into the error of
android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0
it is failing on(in the schedule course alarm() part.
alarmManager.set(AlarmManager.RTC_WAKEUP, time, PendingIntent.getBroadcast(context, nextAlarmId, intentAlarm, PendingIntent.FLAG_ONE_SHOT));

c.mentor = courseMentor;
c.mentorPhone = courseMentorPhone;

c.note = courseNote;
c.notifications = courseNotifications;
return c;
}

Sure the error message says:
android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0
So this means:
CursorIndexOutOfBoundsException think of a cursor as a collection, you are out of bounds
Index 0 requested You wanted to access at position 0 in the collection
with a size of 0 but the collections size is 0 (empty) therefore Out of Bounds.
If you are expecting your database schema to be correct you should not use getColumnIndex but use getColumnIndexOrThrow https://developer.android.com/reference/android/database/Cursor#getColumnIndexOrThrow(java.lang.String) that way you will fail fast and see which part of your data is incorrect.
But yeah basically your cursor is empty, check the query that you are doing. You can also breakpoint on a cursor, and to try alternative queries on teh content resolver.
You could also use a Tool like Stetho, to inspect your on device database to see if it has any data (and practice some queries)
http://facebook.github.io/stetho/
Or move away from cursors altogther and use opne of the newer recommended database access libraries like Room:

Android widget becomes unresponsive after random amounts of time pass

My assumption is that I just do not fully understand widgets yet. Hopefully one of you guru's can see where my logic/thinking is flawed.
Ultimately what happens with my widget is that it eventually becomes unresponsive at very random intervals (usually > 5 hours).
My investigation so far has led me to believe that it's potentially a result of the OS running low on memory and my widget being recreated?
If that's the case, I would have thought that the OnUpdate() method would handle this but potentially I'm wrong here.
I have read pretty much every thread on here regarding widget unresponsiveness. The only one that showed promise for me was this one:
Android Homescreen Widget becomes Unresponsive
but I'm not using a service and not sure I need to.
The goal of the widget is to first check if the user has created a profile. This is done by checking for the existence of a local db along with a user record. If neither of these exist, the widget should display a "Get Started" image (which it does successfully).
Once the user taps on this image, they are launched into a profile creation wizard. Once the profile is created, the widget is updated from the app to display an image along with some caloric intake information.
There are three clickable items on the widget. The image and the two textviews. Each respectively launching a different activity in my app.
Here is the widget class:
public class bbi_widget extends AppWidgetProvider {
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);

android widget update text using activity

I want to update widget item when I Add or Remove item using activity in my WelcomeWidget class onReceive() as
public void onReceive(Context context, Intent intent) {
setup(context);
if (datalist.size() != 0)
{
if (intent.getAction().equals(ACTION_NEXT_TIP)) {
mMessage = getNextMessageIndex();
SharedPreferences.Editor pref = context.getSharedPreferences(
PREFS_NAME, 0).edit();
pref.putInt(PREFS_TIP_NUMBER, mMessage);
pref.commit();
refresh();
}
else if (intent.getAction().equals(ACTION_SETTING))
{
Intent articleIntent = new Intent(context,
LoremActivity.class);
articleIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(articleIntent);
} else {
refresh();
} } }
where refresh method is as :
private void refresh() {
RemoteViews rv = buildUpdate(mContext);
for (int i : mWidgetIds) {
mWidgetManager.updateAppWidget(i, rv);
}
Using Animation as :
AnimationSet farsiTelLogoAnimation = new AnimationSet(true);
RotateAnimation rotate = new RotateAnimation(0, 360,
RotateAnimation.RELATIVE_TO_SELF, 0.5f,
RotateAnimation.RELATIVE_TO_SELF, 0.5f);
rotate.setFillAfter(true);
rotate.setDuration(1000);
farsiTelLogoAnimation.addAnimation(rotate);
}
getting message index
private int getNextMessageIndex() {
return (mMessage + 1) % datalist.size();
}
where buildUpdate () method is as
public RemoteViews buildUpdate(Context context) {
RemoteViews updateViews =
new RemoteViews(context.getPackageName(), R.layout.widget);
// Action for tap on bubble
Intent bcast = new Intent(context,
WelcomeWidget.class);
bcast.setAction(ACTION_NEXT_TIP);
PendingIntent pending = PendingIntent.getBroadcast(context,
0, bcast, PendingIntent.FLAG_UPDATE_CURRENT);
updateViews.setOnClickPendingIntent(R.id.widget, pending);
// RemoteViews updateViews1 = new
RemoteViews(context.getPackageName(), // R.id.setting);
Intent bcast1 = new Intent(context, WelcomeWidget.class);
bcast1.setAction(ACTION_SETTING); PendingIntent pending1 =
PendingIntent.getBroadcast(context,
0, bcast1, PendingIntent.FLAG_UPDATE_CURRENT);
updateViews.
setOnClickPendingIntent(R.id.setting, pending1);
// Tip bubble text if (mMessage >= 0) { // String[] parts =
sNewlineRegex.split(mTips[mMessage], 2);
String to = datalist.get(mMessage).getFrom();
String from = datalist.get(mMessage).getTo();
String rate = datalist.get(mMessage).getRate();
// Look for a callout graphic referenced in the text Matcher m =
sDrawableRegex.matcher(to);
if (m.find()) {
String imageName = m.group(1);
int resId = context.getResources().getIdentifier(
imageName, null, context.getPackageName());
// updateViews.setImageViewResource(R.id.tip_callout, resId);
// updateViews.setViewVisibility(R.id.tip_callout,
// View.VISIBLE);
to = m.replaceFirst(""); } else {
// updateViews.setImageViewResource(R.id.tip_callout, 0);0
// updateViews.setViewVisibility(R.id.tip_callout, View.GONE); }
updateViews.setTextViewText(R.id.to, to);
updateViews.setTextViewText(R.id.from, from);
updateViews.setTextViewText(R.id.rate, rate);
updateViews.setTextViewText(
R.id.tip_footer,
context.getResources().getString(R.string.pager_footer,
(1 + mMessage), datalist.size()));
updateViews.setViewVisibility(R.id.tip_bubble, View.VISIBLE);
}
else {
updateViews.setViewVisibility(R.id.tip_bubble, View.INVISIBLE);
}
return updateViews;
}
where Button click event reload widget

I don't really understand your code because the format is horrible.
Anyway, to update a widget from your activity you can send a Broadcast intent with APPWIDGET_UPDATE. Use the following code:
Intent intent = new Intent(YourActivity.this, YourWidgetProvider.class);
intent.setAction("android.appwidget.action.APPWIDGET_UPDATE");
int ids[] = AppWidgetManager.getInstance(getApplication()).getAppWidgetIds(new ComponentName(getApplication(), ASquareAnalogClockProvider.class));
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS,ids);
sendBroadcast(intent);
Hope it helps :)

Download Manager failed the download

EDIT: I found the problem from logcat:

But I still need to know which format to use to parse url for DownloadManager.

The IllegalArgumentException occurs when the URL contains illegal characters such as [ ]. As mentioned in the comments, you need to encode such characters using URLEncoder.
I implemented it this way in my code -
private String checkUrl(String url) {
if(url.contains("[")) {
String[] a = url.split("\\[");
String b = "[" + a[1]; //contains text after [ e.g. [DJKANG.Com].mp3
url = a[0] + URLEncoder.encode(b, "UTF-8"); // encodes illegal characters
}
return url;
}

Allowing icon to change from user input

I am allowing the user to change the icon in the class Personalize by sending a request code holding an image from a user gallery.
The setIconImageinWidget() method sends the result here (in Drag_and_Drop_App):
else if(requestCode == RESULT_ICON){
byte[] byteArray = data.getByteArrayExtra("myIconBitmap");
Bitmap myIcon = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
setBackgroundImageForIcon(myIcon);
Log.d("Drag_and_Drop_App", "Icon is set");
}
}
Here is the setBackgroundImageForIcon method:
#SuppressLint("NewApi")
private void setBackgroundImageForIcon(Bitmap bitmap) {
ImageView ivICON = (ImageView) findViewById(R.id.bwidgetOpen);
Drawable dq = new BitmapDrawable(getResources(), bitmap);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
ivICON.setImageDrawable(dq);
} else {
ivICON.setImageDrawable(dq);
Log.d("Drag_and_Drop_App", "Icon is set");
}
}
This returns no errors but the icon is not changed at all based on whatever picture the user chooses to use.
After looking around a while I realized that I would have to change the app widget provider section of my coding here:
package com.example.awesomefilebuilderwidget;
IMPORTS
public class AFBWidget extends AppWidgetProvider{
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
// TODO Auto-generated method stub
super.onUpdate(context, appWidgetManager, appWidgetIds);
Random r = new Random();
int randomInt = r.nextInt(1000000000);
String rand = String.valueOf(randomInt);
final int N = appWidgetIds.length;
for (int i = 0; i < N; i++){
int awID = appWidgetIds[i];
RemoteViews v = new RemoteViews(context.getPackageName(), R.layout.widget);
v.setTextViewText(R.id.tvwidgetUpdate, rand);
Intent configIntent = new Intent(context, Drag_and_Drop_App.class);
PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, PendingIntent.FLAG_UPDATE_CURRENT);
v.setOnClickPendingIntent(R.id.bwidgetOpen, configPendingIntent);
//me trying to set the Bitmap from the above classes somehow... v.setImageViewBitmap(R.id.bwidgetOpen, R.id.);
appWidgetManager.updateAppWidget(awID, v);
}
}
#Override
public void onDeleted(Context context, int[] appWidgetIds) {
// TODO Auto-generated method stub
super.onDeleted(context, appWidgetIds);
Toast.makeText(context, "Thanks for checking us out!", Toast.LENGTH_SHORT).show();
}
}
And the imageView I am changing is this:
<ImageView
android:id="#+id/bwidgetOpen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"
android:contentDescription="#string/desc"/>
in Widget.xml
How can I change my Widget Provider so that it will allow the changing of the icon?
I know this is a lot to read but any help is apperciated!
UPDATED:
#SuppressLint("NewApi")
private void setBackgroundImageForIcon(Bitmap bitmap) {
Log.d("Drag_and_Drop_App", "Icon...");
ImageView ivICON = (ImageView) findViewById(R.id.bwidgetOpen);
BitmapDrawable dq = new BitmapDrawable(getResources(), bitmap);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
// ivICON.setImageDrawable(dq);
ivICON.setImageResource(R.drawable.pattern1);
} else {
// ivICON.setImageDrawable(dq);
ivICON.setImageResource(R.drawable.pattern1);
Log.d("Drag_and_Drop_App", "Icon is set");
}
}
