broadcastreceiver

Background When the user downloads a new image or captures one using the camera, the gallery app will get updated to show the new images. I need to be notified of each new image as soon as it was created, no matter how it was created (camera, browser,...) , just as the gallery app shows. The problem As it turns out there is a mediaScanner Android component that is responsible for scanning all types of media files, and when it finishes, it's supposed to send an intent " MEDIA_SCANNER_FINISHED " (as shown on this example ) . So I've added the next code , hoping it will show a toast each time the

I have an widget and I must update the widget when action android.media.RINGER_MODE_CHANGED occurs. I have the folowing broadcast receiver: public void onReceive(Context context, Intent intent) { AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context.getApplicationContext()); ComponentName thisWidget = new ComponentName(context.getApplicationContext(), ExampleAppWidgetProvider.class); int[] appWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget); if (appWidgetIds != null && appWidgetIds.length > 0) { for (int widgetId : appWidgetIds) { RemoteViews remoteViews = new

I'm new to android. I want to receive information via broadcastreceiver ( onReceive ) to know that if user enable/disable "Portable Wi-Fi Hotspot" (Settings->Wireless &Networks->Tethering & portable hotspot) . Check this link And I found that there is " android.net.wifi.WIFI_AP_STATE_CHANGED " but it was set to hidden. Any how I can use that ??? Thanks in advance to receive enable/disable "Portable Wi-Fi Hotspot" events you will need to register an Receiver for WIFI_AP_STATE_CHANGED as : mIntentFilter = new IntentFilter("android.net.wifi.WIFI_AP_STATE_CHANGED"); registerReceiver(mReceiver,

I have created BroadcastReceiver to schedule my Service execution every 30 seconds. This is what I have in AndroidManifest.xml : <receiver android:name="MyScheduleReceiver" > <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <action android:name="android.intent.action.QUICKBOOT_POWERON" /> </intent-filter> </receiver> This is working great now, but only after I added QUICKBOOT_POWERON action. Before that I had only BOOT_COMPLETED and when I reboot emulator or phone while debugging, my service would never start. So my question is what is the difference between these

Is there a possibility of handling the data displayed on call cost dialogue received by prepaid user. I want to save all the balance reduction for along with call duration in my sqlite db. As we learn from the already famous blog post As a start, look at the PhoneUtils class in the Android source code. [...] Specifically, looking at line 217, an intent with the name “com.android.ussd.IExtendedNetworkService” is being composed. So what you need to do is implement your own service that responds to that intent . The service needs to be implemented according to the IExtendedNetworkService.aidl

I know that onReceive() of the Broadcast receiver and handleMessage() of Handler run on the same UI thread. Suppose I want to communicate between two services, within the same app (process) . I can extend a broadcast receiver class and register an event OR a Handler and then pass its instance to the other service to be used for sendMessage() calls. In both the cases I would need to add some new switch case. But which approach is more efficient ? Lets assume that the code is thread safe (no UI updations). I can extend a broadcast receiver class and register an event If you mean that you are

I have two apps that I have complete control over. Both are signed with the same cert and both use the exact same intent filter. One sends the broadcast from a fragment, the other is suppose to receive it and do something. This however is not working: Strings.FILTER_INIT_REGISTER = "com.app.FILTER_INIT_REGISTER" Intent intent = new Intent(Strings.FILTER_INIT_REGISTER); getActivity().sendBroadcast(intent); I have registered the receiver in the Manifest app tag for the app containing the ReportingReceiver class: <receiver android:name=".receivers.ReportingReceiver" android:exported="true" >
