How to make a widget work on the click of a button?

My Midget works perfectly when i drag and drop it on my desktop. However, I want to perform my widget's action from my TestActivity's Interface as well, on button click.
Here is my Widget's receiver-
package com.droideilhan.ultrasimpletaskkiller;
public class USTaskKillerWidget extends AppWidgetProvider {
public static String ACTION_WIDGET_RECEIVER = "ActionReceiverUltraSimpleTaskKillerWidget";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);
Intent clicSurBtnKillIntent = new Intent(context, USTaskKillerWidget.class);
clicSurBtnKillIntent.setAction(ACTION_WIDGET_RECEIVER);
PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, clicSurBtnKillIntent, 0);
remoteViews.setOnClickPendingIntent(R.id.btnKill, actionPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}
#Override
public void onReceive(Context context, Intent intent) {
// v1.5 fix that doesn't call onDelete Action
final String action = intent.getAction();
if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
final int appWidgetId = intent.getExtras().getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
this.onDeleted(context, new int[] { appWidgetId });
}
} else {
// On a cliqué sur le bouton
if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) {
// Liste des packages à ne pas tuer.
List<String> reservedPackages = new ArrayList<String>();
reservedPackages.add("system");
reservedPackages.add("com.android.launcher2");
reservedPackages.add("com.android.inputmethod.latin");
reservedPackages.add("com.android.phone");
reservedPackages.add("com.android.wallpaper");
reservedPackages.add("com.google.process.gapps");
reservedPackages.add("android.process.acore");
reservedPackages.add("android.process.media");
// On tue tous les processus, sauf ceux de la liste
int compteProcessusTues = 0;
ActivityManager am = (ActivityManager) context.getSystemService(Activity.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> listeProcessus = am.getRunningAppProcesses();
for(RunningAppProcessInfo processus : listeProcessus) {
//Log.d("TKTKTK", "========="+processus.pid+" : "+processus.processName);
String packageName = processus.processName.split(":")[0];
if (!context.getPackageName().equals(packageName) && !reservedPackages.contains(packageName)) {
am.restartPackage(packageName);
compteProcessusTues++;
}
}
// Auto-kill (désactivé dans le cas d'un widget)
//am.restartPackage(context.getPackageName());
}
super.onReceive(context, intent);
}
}
}

Problem- Widgets's action never gets called, no force closes, no errors.
Here is the button in my TestActivity (well this is what i have tried so far)
public void test(View view) {
Intent intent = new Intent();
intent.setAction("android.appwidget.action.APPWIDGET_UPDATE");
sendBroadcast(intent);
intent.setAction("com.droideilhan.android.widget.buttons.ButtonWidget.ACTION_WIDGET_RECEIVER");
sendBroadcast(intent);
}

Widget Flashlight

I want to create a widget for turning on/off the flashlight and this is What I did:
Widget class:
public class FlashLightWidget extends AppWidgetProvider {
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId) {
Intent receiver = new Intent(context, FlashLightReceiver.class);
receiver.setAction("NINJA_KRZYSZTOF_FLASHLIGHT");
receiver.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetId);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, receiver, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.flash_light_widget);
views.setOnClickPendingIntent(R.id.imageView, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
}
#Override
public void onEnabled(Context context) {
}
#Override
public void onDisabled(Context context) {
}
}
My BroadcastReceiver:
public class FlashLightReceiver extends BroadcastReceiver {
private boolean isLightOn = false;
private Camera camera;
#Override
public void onReceive(Context context, Intent intent) {
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.flash_light_widget);
if (isLightOn) {
views.setImageViewResource(R.id.imageView, R.drawable.light_off);
} else {
views.setImageViewResource(R.id.imageView, R.drawable.light_on);
}
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
appWidgetManager.updateAppWidget(new ComponentName(context, FlashLightWidget.class), views);
if (isLightOn) {
if (camera != null) {
camera.stopPreview();
camera.release();
camera = null;
isLightOn = false;
}
} else {
camera = Camera.open();
if (camera == null) {
Toast.makeText(context, "No camera found", Toast.LENGTH_SHORT).show();
} else {
Camera.Parameters param = camera.getParameters();
param.setFlashMode(Camera.Parameters.FLASH_MODE_TORCH);
try {
camera.setParameters(param);
camera.startPreview();
isLightOn = true;
} catch (Exception e) {
Toast.makeText(context, "No LED found", Toast.LENGTH_SHORT).show();
}
}
}
}
}
AndroidManifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="ninja.majewski.jutswidgetflashlight">
<uses-permission android:name="android.permission.CAMERA" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"

<receiver android:name=".FlashLightWidget">

<receiver android:name=".FlashLightReceiver">
<intent-filter>
<action android:name="NINJA_KRZYSZTOF_FLASHLIGHT" />
</intent-filter>
</receiver>
</application>
</manifest>
The problem is when I click this ImageView on widget layout it switches on the flashlight but when I want to switch it off it crashes ("sorry but app was stopped..." message).
What am I doing wong?

You don't state the actual error message but I am getting a crash when pressing the widget a 2nd time as well. I'm seeing:
java.lang.RuntimeException: Fail to connect to camera service
It looks to me like your problem is because isLightOn is always false, so your code is attempting to re-open the already open camera. To fix this specific issue, make isLightOn static, like this:
private static boolean isLightOn = false;

Clikable widget button doesn't do anything when clicked

I have a widget which installs OK on the screen but when I press the button on it it's supposed to open a activity in my project. I've tried everything, but it still doesn't work.
Here is my code:
public class MyWidgetProvider extends AppWidgetProvider {
public static String INTENT_ACTION="OPEN_SECOND_VIEW_ACTIVITY";
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
final int N = appWidgetIds.length;
for (int i = 0; i < N; i++) {
int appWidgetId = appWidgetIds[i];
Intent intent = new Intent(context, SecondViewActivity.class);
intent.setAction(INTENT_ACTION);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
views.setOnClickPendingIntent(R.id.widgetButton, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
#Override
public void onReceive(Context context, Intent intent) {
Log.v("MT","onReceive called");
super.onReceive(context, intent);
Log.v("MT","constructor passed");
Log.v("MT",intent.getAction());
if (intent.getAction().equals(INTENT_ACTION)) {
Log.v("MT","works");
Toast.makeText(context, "works", Toast.LENGTH_SHORT).show();
}
}
}
Here the activity(which is not the main acitivity which I want to open)
public class SecondViewActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_dialog);
Intent intent = getIntent();
Bundle extras = intent.getExtras();
int mAppWidgetId = -1;
if (extras != null) {
mAppWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
}
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(getApplicationContext());
RemoteViews views = new RemoteViews(getApplicationContext().getPackageName(), R.layout.widget_layout);
appWidgetManager.updateAppWidget(mAppWidgetId, views);
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, resultValue);
finish();
}
And here my manifest

The problem with your code is that PendingIntent created in a wrong way. Based on the code it looks like You want to receive that intent in AppWidgetProvider. If so, then you need to provide providers class for intent (instead of activity class):
final Intent intent = new Intent(context, MyWidgetProvider.class);
And get broadcast PendingIntent, not activity one:
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, appWidgetId, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Refer to PendingIntent documentation for additional details of it's usage.
Below is working example of activity launch by click from AppWidget:
#Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
}
static void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
final Intent intent = new Intent(context, MyWidgetProvider.class);
intent.setAction(INTENT_ACTION);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, appWidgetId, intent, PendingIntent.FLAG_UPDATE_CURRENT);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
views.setOnClickPendingIntent(R.id.widgetButton, pendingIntent);
// Tell the AppWidgetManager to perform an update on the current app widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if (intent.getAction().equals(INTENT_ACTION)) {
Toast.makeText(context, "works", Toast.LENGTH_SHORT).show();
final Intent activityIntent = new Intent(context.getApplicationContext(), MyActivity.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(activityIntent);
}
}

appwidget onupdate not called as well as button click not working after some time

I am having a simple widget which has three button for three different system operation.
I made a XML in xml folder and the code is below.

Here is the MainActivity's code which extends AppWidgetProvider
public class MainActivity extends AppWidgetProvider{

views.setOnClickPendingIntent(R.id.button1, getPendingSelfIntent(context, ABC));
views.setOnClickPendingIntent(R.id.button3, getPendingSelfIntent(context, CFV));
appWidgetManager.updateAppWidget(currentWidgetId,views);
Toast.makeText(context, "widget used", Toast.LENGTH_SHORT).show();
}
}
protected PendingIntent getPendingSelfIntent(Context context, String action) {
Log.v("ONMESSAGE", action);
Intent intent = new Intent(context, getClass());
intent.setAction(action);
return PendingIntent.getBroadcast(context, 0, intent, 0);
}
#Override

It was all working when first installed however after I change the code and then reinstall, now its not working. I am making widget for the first time.
N:B:- just tried installing it in a new phone and now it is working, I think after some time, it either does not get updated or stops receiving pending intent from widget!
