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");
}

the android widget content when device rotated are suddenly gone.
do I have to repopulate them when device is rotated? but the widget dont have onconfiguration change to listen to.
also I used alarmmanager with service to populate the widget for new app (adding to viewflipper) to display every 1 minute.
widget code:

// check if alarms not created, create 1
if(!GlobalStorage.tempStorage.containsKey(Widget_2_6.class.toString() + appWidgetIds[i]))

createAlarmService(context, appWidgetIds[i]);
// put to hash for alarms created
GlobalStorage.tempStorage.put(Widget_2_6.class.toString() + appWidgetIds[i], 0);

is there anything i missed?
Ok. got it working, the problem is with the RemoteView's behavior.(NOTE: RemoteView will send the latest changes to views needing a refresh/update)
so what I did was instead of using manager.updateAppWidget(widgetID, views); on all occasion.
I used a flag to know when to use updateAppWidget or partiallyUpdateAppWidget.
below is the modified code under the buildUpdate function from above listing, replacing manager.updateAppWidget(widgetID, views); into:
if(!GlobalStorage.tempStorage.containsKey(_class.toString() + widgetID) || GlobalStorage.tempStorage.get(_class.toString() + widgetID) == 0)
{
Log.e("buildUpdate -- WidgetUpdateService", "buildUpdate -- WidgetUpdateService: either not in collection or is 0: do full update");
manager.updateAppWidget(widgetID, views);
}
else
{
Log.e("buildUpdate -- WidgetUpdateService", "buildUpdate -- WidgetUpdateService: is not 0: do partial update");
manager.partiallyUpdateAppWidget(widgetID, views);
}
with the modified logic, when the view is needing for a refresh/update (which we cannot control most of the time like orientation change). it will not override the whole view and just the partial view.
I have a clock widget that updates every minute. It renders a bitmap and replaces an imageview. This is to use a custom font in a widget. Below I showed the important pieces of my code. My problem is that the widget is there, but nothing shows up. I can still tap the widget to bring up the settings, so I know it's there. It's like the service update isn't working correctly in Kitkat but it does in Lollipop. Any suggestions?

EDIT:
The issue seems to have to do with the Bitmap rendering. I replaced the imageview with a textview and it worked. So the Bitmap isn't displaying in KitKat, but it does in Lollipop
public Bitmap buildUpdate(String time, int AMPM, String date) {
Log.v("Penguin", "Building time string:" + time);
clockSettings = this.getSharedPreferences("ClockSettings", 0);
boolean showDate = clockSettings.getBoolean("showDate", true);
boolean showampm = clockSettings.getBoolean("ampm", true);
boolean leading0 = clockSettings.getBoolean("leading0", true);
textColor = clockSettings.getInt("clockColor", Color.WHITE);
int dateColor = clockSettings.getInt("dateColor", Color.WHITE);
Bitmap myBitmap = Bitmap.createBitmap(2500, 1100, Bitmap.Config.ARGB_8888);
int fontSize = 425;
Canvas myCanvas = new Canvas(myBitmap);
Paint paint = new Paint();
Typeface clock = Typeface.createFromAsset(this.getAssets(), "fonts/PressStart2P.ttf");
paint.setAntiAlias(true);
paint.setSubpixelText(true);
paint.setTypeface(clock);
paint.setStyle(Paint.Style.FILL);
paint.setColor(textColor);
paint.setTextSize(fontSize);
paint.setTextAlign(Paint.Align.CENTER);
myCanvas.drawText(time, myBitmap.getWidth() / 2, fontSize+200, paint);
paint.setTextSize(100);
if(showampm) {
// alert("AMPM");
String ampm = "AM";
if (AMPM == 1) ampm = "PM";
myCanvas.drawText(ampm, (myBitmap.getWidth() / 2) + ((time.length() * fontSize) / 2) + 100, 300, paint);
}
paint.setTextSize(125);
if(showDate) {
paint.setColor(dateColor);
myCanvas.drawText(date, myBitmap.getWidth() / 2, (myBitmap.getHeight() / 2 + 400), paint);
}
return myBitmap;
}
So the issue was that the size limit for my older phone running KitKat only allows for texture sizes no bigger than 2048x2048 pixels. My bitmap was 2500x1100, so scaling it down has fixed the issue
I have a problem to make a customizable AppWidget : I don't know how to do... I tried to update appearance regularly with this function :
public static void updateApparence(Context context)
{
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
for(int i = 0 ; i < widgetLayoutIds.length ; i++)
{
int[] appWidgetIds = appWidgetManager.getAppWidgetIds(new ComponentName(context, appWidgetProvidersClass[i]));
RemoteViews views = new RemoteViews(context.getPackageName(), widgetLayoutIds[i]);
views.setInt(R.id.widget_background, "setBackgroundColor", prefs.getInt(SettingsApparence.BACKGROUND_COLOR, 0xFFFFFFFF));
views.setInt(R.id.matiere, "setTextColor", prefs.getInt(SettingsApparence.COULEUR_MATIERE, 0xFF666666));
views.setInt(R.id.horaires, "setTextColor", prefs.getInt(SettingsApparence.COULEUR_HORAIRES, 0xFF888888));
views.setInt(R.id.salle, "setTextColor", prefs.getInt(SettingsApparence.COULEUR_SALLE, 0xFF888888));
Bitmap bm = BitmapFactory.decodeFile(context.getFilesDir() + PATH_CLE);
if(bm == null)
{
bm = BitmapFactory.decodeResource(context.getResources(), R.drawable.settings_icon);
bm = changeImageColor(bm, prefs.getInt(SettingsApparence.COULEUR_CLE, 0xFF000000));
}
views.setBitmap(R.id.settings, "setImageBitmap", bm);
bm = BitmapFactory.decodeFile(context.getFilesDir() + PATH_CALENDRIER);
if(bm == null)
{
bm = BitmapFactory.decodeResource(context.getResources(), R.drawable.calendrier_icon);
bm = changeImageColor(bm, prefs.getInt(SettingsApparence.COULEUR_CALENDRIER, 0xFF000000));
}
views.setBitmap(R.id.emploi_du_temps, "setImageBitmap", bm);
appWidgetManager.updateAppWidget(appWidgetIds, views);
}
}
But sometimes, the original appearance (in R.layout.widget, in appWidgetProvidersClass[]) reappear...
How can I do that ?
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 {

From my app, I do update these values in the widget using remoteViews.
Here is the helper class in my app:
public class WidgetHelper {
public static void UpdateCalorieIntake(int newValue, Context context) {
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.initial_widget_layout);
ComponentName thisWidget = new ComponentName(context, bbi_widget.class);
remoteViews.setTextViewText(R.id.calTextView, "Calories in " + String.valueOf(newValue));
appWidgetManager.updateAppWidget(thisWidget, remoteViews);
}
public static void UpdateWidgetSurplus(int newValue, Context context) {
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.initial_widget_layout);
ComponentName thisWidget = new ComponentName(context, bbi_widget.class);
if (newValue > 0) {
remoteViews.setTextViewText(R.id.surp_def_widgettextView, "Caloric Surplus " + String.valueOf(newValue));
remoteViews.setTextColor(R.id.surp_def_widgettextView, context.getResources().getColor(R.color.surplus_ball_color));
} else {
remoteViews.setTextViewText(R.id.surp_def_widgettextView, "Caloric Deficit " + String.valueOf(newValue));
remoteViews.setTextColor(R.id.surp_def_widgettextView, context.getResources().getColor(R.color.calorie_crush_ball));

int totalCalsToday = db.GetTodaysCalorieIntakeForWidget();
int bmrWithAct = db.GetBMRPlusActivity();
int additionalCalsCrushed = db.GetTodaysCaloriesBurnedForWidget();
int surp = totalCalsToday - (bmrWithAct + additionalCalsCrushed);
if (surp < 0)
surp = 0;
int def = totalCalsToday - (bmrWithAct + additionalCalsCrushed);
if (def > 0)

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 :)
