I am making an Android widget to display real time transportation information based on bus stop numbers. It displays the next 3 bus arrivals for the stop number and has a button where the user can refresh the data. That was working ok until I tried adding my widget configuration activity.
Now when you select the widget, a configuration screen is opened where you enter your bus stop number. Once you do that the widget is added to the home screen, but it will not execute the method to gather data and the refresh button will not work for that either. I have not been able to figure out why.
WidgetConfig
public class WidgetConfig extends Activity implements OnClickListener{
EditText info;
AppWidgetManager awm;
Context c;
int awID;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.widget_config);
Button b = (Button)findViewById(R.id.bWidgetConfig);
b.setOnClickListener(this);
c = WidgetConfig.this;
//getting info about the widget that launched this activity
Intent i = getIntent();
Bundle extras = i.getExtras();
if (extras != null){
awID = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
}else{
finish();
}
awm = AppWidgetManager.getInstance(c);
}
public void onClick(View v) {
// TODO Auto-generated method stub
info = (EditText)findViewById(R.id.etWidgetConfig);
String e = info.getText().toString();
RemoteViews views = new RemoteViews(c.getPackageName(), R.layout.widget_layout);
views.setTextViewText(R.id.tvStopNum, e);
Intent in = new Intent(c, WidgetConfig.class);
PendingIntent pi = PendingIntent.getActivity(c, 0, in, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.tvStopNum, pi);
awm.updateAppWidget(awID, views);
Intent result = new Intent();
result.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, awID);
setResult(RESULT_OK, result);
finish();
}
AppWidgetProvider
public class MyWidgetProvider extends AppWidgetProvider {
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds){
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
// Create a new intent that will target this class
Intent intent = new Intent(context, MyWidgetProvider.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[0]);
intent.setAction("update");
// Create a new PendingIntent which will be run whenever the refresh button is pressed
// This PendingIntent will run the intent we just created before this
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.button1, pi);
// Manually run the AsyncTask to initially populate the 5 question fields
new RTPIinformation().execute(context);

I'm trying to create a Widget which update the text every time I press the save button and get the information from 2 editText. When I press the button to send by Intent the variables it throws
"android.content.ActivityNotFoundException: Unable to find explicit activity class"
in the logcat. Here my code:
Main.class
public class MainActivity extends AppCompatActivity {
Button save;
EditText Nom;
EditText Cognom;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
save = (Button) findViewById(R.id.save);
Nom = (EditText) findViewById(R.id.editTextNom);
Cognom = (EditText) findViewById(R.id.editTextCognom);
save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i;
i = new Intent(MainActivity.this, NewAppWidget.class);
i.putExtra("NOM",Nom.getText().toString());
i.putExtra("COGNOM",Cognom.getText().toString());
startActivity(i);
}
});
}
}

public class NewAppWidget extends AppWidgetProvider {

Dude first thing is you can not start an widget provider like an activity.
If you want update widget widget from activity you can do like this.
Intent intent = new Intent(this, MyAppWidgetProvider.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
// Use an array and EXTRA_APPWIDGET_IDS instead of AppWidgetManager.EXTRA_APPWIDGET_ID,
// since it seems the onUpdate() is only fired on that:
int[] ids = AppWidgetManager.getInstance(getApplication())
.getAppWidgetIds(new ComponentName(getApplication(), MyAppWidgetProvider.class));
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, ids);
sendBroadcast(intent);
You can pass your parameter to this intent or better you save your values in Shared Preference and use it in your widget provider class in onUpdate method.
I read your widgetprovider class, you will get many errors when using this class. For understanding android widget, you can fork and understand this Github sample.
In this sample you will get how to update widget, how to have multiple widget controls and much more. So i strongly recommend you go through this sample.
AppWidgetProvider extends BroadcastReceiver NOT ACTIVITY
i = new Intent(MainActivity.this, NewAppWidget.class);
startActivity(i);
To use startActivity you need to provide Activity class's child object
NewAppWidget is not an Activity !!
I've created a simple widget have only a button and textView. When I add my widget first time to the homescreen a FC message coming and widget will added. And button click toast message won't work. Only i need to have a toast message when clicking the widget button. I've gone through lots of tutorials but couldn't figure out whats the problem. Any genius who'd like to help..really appriciate the help..Thanks..
widgetProvider.java
public class widgetProvider extends AppWidgetProvider{
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,

final int N = appWidgetIds.length;
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
Intent intent = new Intent(context, widgetProvider.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widgetlayout);
views.setOnClickPendingIntent(R.id.button1, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(AppWidgetManager.ACTION_APPWIDGET_UPDATE)) {

your onUpdate is never called since you overriden the onReceive method.
My widget I've made goes onto the emulator and real device just fine with no errors, but when I go to click on the button to open a new activity on the widget, it doesn't open and all I get in Logcat is this:
10-12 12:54:23.721: I/ActivityManager(289): START u0 {dat=intent: flg=0x10000000 cmp=com.example.awesomefilebuilderwidget/.Drag_and_Drop_App bnds=[56,639][209,735] (has extras)} from pid -1
I don't understand why it doesn't open my activity (Drag_and_Drop_App.java) Here is my code in my AppProvider:
#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, 0);
v.setOnClickPendingIntent(R.id.bwidgetOpen, configPendingIntent);
appWidgetManager.updateAppWidget(awID, v);
}
}
Please note that I also have this coding in my WidgetConfig.java (the screen that first pops up when the widget is installed to collect a name for the widget):
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String e = info.getText().toString();
RemoteViews views = new RemoteViews(c.getPackageName(), R.layout.widget);
views.setTextViewText(R.id.tvConfigInput, e);
Intent in = new Intent(c, Drag_and_Drop_App.class);
in.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, awID);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Make the pending intent unique...
in.setData(Uri.parse(in.toUri(Intent.URI_INTENT_SCHEME)));
PendingIntent pi = PendingIntent.getActivity(c, 0, in, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.bwidgetOpen, pi);
awm.updateAppWidget(awID, views);
Intent result = new Intent();
result.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, awID);
setResult(RESULT_OK, result);
finish();
}
}

In my application, I have a Fragment which is attached to the main activity. This Fragment displays data with the help of an adapter. In the adapter, I have inflated a layout which has a clickable text "Watch From Home". The adapter displays data from the server. I want to show the same data on the home screen and when I click on the "Watch From Home" text, a home screen widget should be created without any user interaction.
I made a receiver MyWidgetProvider.What should the method onClickText() for "Watch From Home" have so that it takes me to the widget? I must admit, I am new to android. Thanks

Simply saying, You can't create a home widget without any user interaction.
Update:
Your receiver tag should start like this:
<receiver
android:name=".MyWidgetProvider"
android:label="My widget label" >
<!-- The rest as is -->
</receiver>
Home Screen Widget can only add to Home Screen directly by user.Only user can add widget as guest to Home Screen or other applications.
Edit:
To see your widget in widgets list:
It is necessary that register your AppWidgetProvider in manifest.
Your App has to have Launcher/Main Activity,and App must be directly run by user,before it be visible in widgets list.This is necessary ,because no broadcastreceiver(and so no AppWidgetProvider),no service,... of your App could not register before your App run directly by user.If you look at your manifest,you will see that your App has no Launcher/Main Activity(it has only a receiver),so it can not run by user and your AppWidgetProvider(that is a broadcastreceiver) will not register and thereupon you can not see your widget in widget list.
This had me scratching my head for a while.
I had the meta-data tag as child of the intent-filter tag, which is wrong. The meta-data is to be child of the receiver tag.
Incorrect version
<receiver
android:name=".AppWidgetReceiver"
android:label="AppWidgetReceiver" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/appwidget_info" />
</intent-filter>
</receiver>
Following is the correct version
<receiver android:name=".AppWidgetReceiver"
android:label="AppWidgetReceiver" >
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="#xml/appwidget_info" />
</receiver>
I have an Android widget that has a configure activity. I also have an ImageView "button" set up on the widget to launch the configure activity, in case the user wants to change his/her preferences after initializing them.
So, basic lifecycle:
User adds the widget
Configure activity pops up, user fills in fields and clicks "Submit"
Widget is added on screen
User taps the ImageView to launch the configure activity
Configure activity pops up, user edits fields
After either hitting "Submit" or backing out, the widget is updated
User can continue to go through steps 5 and 6 as needed.
My problem is at step 5. The very first and only the first time that the user taps the ImageView, it looks like two configure activities are launched. That is, when I back out of the first one, there's still another one "behind" it. On all subsequent launches of the configure activity, however, only one is launched and everything works great.
What could be the problem? I'll post relevant code below.

I think these are the most relevant sections. The places I'm going to be looking further into are in ConfigActivity.java in the submitListener and in the updateDisplayState method in Widget.java
Any help would be awesome! Thanks!
When calling an explicit intent, you should consider using one of the intent flags like FLAG_ACTIVITY_CLEAR_TOP to keep the stack organized. For example:
configIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
You can spot the lack of this flag in some apps like the IMDB app where each click of the Home button adds another instance of the home activity on the stack, so you need to click the Back button as many times to pop through the stack and back out of the app. :)
add to the activity at manifest file android:noHistory="true" and android:excludeFromRecents="true"
it suppose to solve the problem
<activity
android:name=".ConfigActivity"
android:label="#string/app_name"
android:noHistory="true"
android:excludeFromRecents="true">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_CONFIGURE" />
</intent-filter>
</activity>
