I'm making a widget and i know some of my code such as the broadcastReceiver is wrong at the moment but it wont even update to hardcoded setTextViewText.
My problem is I've no idea why this happens and my widget just wont update.
Here's my code i hope someone can figure out where ive gone wrong:
public class Widget extends AppWidgetProvider {
RemoteViews views;
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
int N = appWidgetIds.length;
views = new RemoteViews(context.getPackageName(), R.layout.widget);
for (int i = 0; i < N; i++) {
int appWidgetId = appWidgetIds[i];
IntentFilter batteryLevelFliter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
context.registerReceiver(batteryChangedReceiver, batteryLevelFliter);
String alarm = Settings.System.getString(context.getContentResolver(),
Settings.System.NEXT_ALARM_FORMATTED);
views.setTextViewText(R.id.tvAlarm, alarm);
views.setTextViewText(R.id.tvNextAlarm, "qwertyuiop");
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
private BroadcastReceiver batteryChangedReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
int rawLevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
int level = -1;
if (rawLevel >= 0 && scale > 0) {
level = (rawLevel * 100) / scale;
}
int status = intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
boolean charging = status == BatteryManager.BATTERY_STATUS_CHARGING;
if (charging) {
views.setTextViewText(R.id.tvBattery, "Charging: " + level + "%");
if (level == 100) {
views.setTextViewText(R.id.tvBattery, "Battery Full");
}
} else {
views.setTextViewText(R.id.tvBattery, "Battery: " + level + "%");
}
}
};
}
AppWidgetProvider extends android.content.BroadcastReceiver, so you cannot register new BroadcastReceiver to the your AppWidget's context. In your code, you will not receive battery event from your BroadcastReceiver. Refer these previous questions. :)

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);

I can't update the widget when is in charging state. The battery level stay the same. What is wrong in my code?
public class BatteryStatusWidgetActivity extends AppWidgetProvider {
/** Called when the activity is first created. */
private String batteryLevel = "init";
private String temperatura = "init";
private int widgetImageFrame = R.drawable.full;
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
context.getApplicationContext().registerReceiver(this,
new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
updateView(context);
}
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().contentEquals(
"com.sec.android.widgetapp.APPWIDGET_RESIZE")
|| intent.getAction().equals(
"android.appwidget.action.APPWIDGET_UPDATE_OPTIONS")) {
} else {
int rawlevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
int level = -1;
level = (rawlevel * 100) / scale;
batteryLevel = level + "%";
// temperatura
int temperature = intent.getIntExtra(BatteryManager.EXTRA_TEMPERATURE,
-1) / 10;
temperatura = temperature + "°C";
widgetImageFrame = R.drawable.full;
updateView(context);
}
super.onReceive(context, intent);
}
public void updateView(Context context) {
RemoteViews thisViews = new RemoteViews(context.getApplicationContext()
.getPackageName(), R.layout.widget_layout);
thisViews.setTextViewText(R.id.widget_text, batteryLevel + " | "
+ temperatura);
thisViews.setImageViewResource(R.id.imageView1, widgetImageFrame);
ComponentName thisWidget = new ComponentName(context,
BatteryStatusWidgetActivity.class);
AppWidgetManager.getInstance(context).updateAppWidget(thisWidget,
thisViews);
}
}
This is the main of widget

<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" android:initialLayout="#layout/widget_layout" android:minWidth="40dp" android:minHeight="40dp" android:updatePeriodMillis="3000" />
So what is the problem? android:updatePeriodMillis="3000"?
The updatePeriodMillis attribute defines how often the App Widget framework should request an update from the AppWidgetProvider by calling the onUpdate() callback method.
from http://developer.android.com/guide/topics/appwidgets/index.html#MetaData
I found this code to create a battery widget:
public class BatteryStatusWidgetActivity extends AppWidgetProvider {
/** Called when the activity is first created. */
private String batteryLevel = "init";
private int widgetImageFrame = R.drawable.widget_batt_frame01;
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
context.getApplicationContext().registerReceiver(this, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
updateView(context);
}
#Override
public void onReceive(Context context, Intent intent) {
int rawlevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
int level = 65;
level = (rawlevel * 100) / scale;
String batteryLevel = level + "%";
widgetImageFrame = R.drawable.widget_batt_frame01;
updateView(context);
super.onReceive(context, intent);
}
public void updateView(Context context) {
RemoteViews thisViews = new RemoteViews(context.getApplicationContext().getPackageName(), R.layout.widget_layout);
thisViews.setTextViewText(R.id.widget_text, batteryLevel);
thisViews.setImageViewResource(R.id.imageView1, widgetImageFrame);
ComponentName thisWidget = new ComponentName(context, BatteryStatusWidgetActivity.class);
AppWidgetManager.getInstance(context).updateAppWidget(thisWidget, thisViews);
}
This will display in the widget only the number of battery level. I mean "65" and i want display "65%". But if i try to write something like batteryLevel = Integer.toString(level+"%"); i get error.. How can i do it?
int level = 65;
String batteryLevel = level + "%";
Try this it will work
int level= 65;
String batterylevel = String.valueOf(level)+"%";
just replace your code in onReceive() to the following,
#Override
public void onReceive(Context context, Intent intent) {
int rawlevel = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
int scale = intent.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
int level = -1;
level = (rawlevel * 100) / scale;
batteryLevel = level+"%";
widgetImageFrame = R.drawable.widget_batt_frame01;
updateView(context);
super.onReceive(context, intent);
}
The basic reason you get an error for Integer.toString(level+"%") is Integer.toString() method used here accepts an int value but not a String value. level+"%" is a String value
Change it to this:
int level = -1
level = (rawlevel * 100) / scale;
String batteryLevel = level + "%";
I have a battery widget, and for some reason it does not receive the BATTERY_PLIGGED_AC integer when the phone is plugged into AC.
I have another widget for the BATTERY_PLUGGED_USB which works just fine.
I can't see anything wrong with my code:
public void onReceive(Context context, Intent intent) {
status = intent.getIntExtra("status", BatteryManager.BATTERY_STATUS_UNKNOWN);
batterylevel = intent.getIntExtra("level", 0);
updateAppWidget(context);
}
public void updateAppWidget(Context context){
RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.androidbatterywidget_layout);
updateViews.setTextViewText(R.id.textView1, " " + batterylevel + "%");
if (status == BatteryManager.BATTERY_PLUGGED_USB)
updateViews.setImageViewResource(R.id.imageView2, R.drawable.usb);
else if (status == BatteryManager.BATTERY_PLUGGED_AC)
updateViews.setImageViewResource(R.id.imageView2, R.drawable.bolt);
else
updateViews.setImageViewResource(R.id.imageView2, R.drawable.empty);
Hopefully someone will be able to spot what I have done wrong. Thanks!
Figured a way around. Sorry for this post I should have looked at it for a little longer myself. For future reference if people seem to have the same problem, it seems to me that the USB value is bundled with the BatteryManager.BATTERY_STATUS_UNKNOWN, but not the AC. So instead all i did was assign a new private int charging, to the value of the BatteryManager.BATTERY_PLUGGED_AC variable. If this is true (and the device is charging throygh AC), then the value is 1, so I simply replaced my previous if statement with
if (charging == 1)
updateViews.setImageViewResource(R.id.imageView2, R.drawable.bolt);
Now the code reads;
private int batterylevel = 0;
private int status;
private int charging;
private BroadcastReceiver myReceiver = new BroadcastReceiver()
{
public void onReceive(Context context, Intent intent)
{
status = intent.getIntExtra("status", BatteryManager.BATTERY_HEALTH_UNKNOWN);
charging = intent.getIntExtra("plugged", BatteryManager.BATTERY_PLUGGED_AC);
batterylevel = intent.getIntExtra("level", 0);
updateAppWidget(context);
}
public void updateAppWidget(Context context){
RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.androidbatterywidget_layout);
updateViews.setTextViewText(R.id.textView1, " " + batterylevel + "%");
if (charging == 1)
updateViews.setImageViewResource(R.id.imageView2, R.drawable.bolt);
else if (status == BatteryManager.BATTERY_PLUGGED_USB)
updateViews.setImageViewResource(R.id.imageView2, R.drawable.usb);
else
updateViews.setImageViewResource(R.id.imageView2, R.drawable.empty);
Im sure that there is a far more "majestic" way to do this, but i was just puzzled at why the USB int was passed if it was plugged into USB (2), but not the AC (1).
Thanks!
I tried solving my problem using this link
update - I figured out that there is something wrong with the setter of the pending intent- every time I click on the imageview- the intent sends the extre details of the last defined widget-
meaning that the other pending intents that where defined on the pre-added widgets were run-over by the newer widgets
I have an app widget that shows a picture chosen by the user.(many widgets- many pictures)
my problem is: no matter which widget on screen I press - only the last added widget gets updated:

The problem isn't your configActivity, the problem is in your widgetProvider. I had the same problem as you did but solved using the link you specified. You need to set the "hacked" intent on your configIntent in buildRemoteView.
I had the same problem when I tested my application on emulator of 2.2 or 2.3 version. On a real device everything should work fine. Moreover, in my case emulator 4.0 worked properly. In any case I recommend you to test it on a real device.
