由 谁说胖子不能爱 提交于 2019-11-28 02:13:36
I know this question has been asked many times but i am unable to find the right direction. I have registered BroadcastReceiver which I want to trigger when the Android System Date is changed automatically but its not firing. I have used the following approaches: 1 IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Intent.ACTION_TIME_CHANGED); registerReceiver(new DateTimeChangeReceiver (), intentFilter); 2-> AndroidManifest.xml <receiver android:name=".DateTimeChangeReceiver "> <intent_filter> <action android:name="android.intent.action.DATE_CHANGED"/> </intent_filter> <

Widget sending multiple types of intents

由 白昼怎懂夜的黑 提交于 2019-11-28 02:11:51
问题 I am building a widget that has multiple buttons, each one sending off its own intent to a broadcast receiver. The broadcast receiver is suppose to display a Toast message based on which button was pushed. The code currently looks like this: public class WidgetProvider extends AppWidgetProvider { @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds){ ComponentName thisWidget = new ComponentName(context, WidgetProvider.class); int[] allWidgetIds

Broadcast-receiver which always receives broadcast (even in background) for API Level +26

由 安稳与你 提交于 2019-11-28 01:46:43
问题 I'm posing this as Q&A style because I found this idea working. And it's a fix to the hard problem to crack for beginners with Android. Google has deprecated registering Broadcast Receiver into manifest like this below from API Level 26+ ( Except Some ) <receiver android:name=".MyBroadcastReceiver" android:exported="true"> <intent-filter> <action android:name="android.net.wifi.STATE_CHANGE" /> </intent-filter> </receiver> But, If one wants to receive particular device state changes like

Android capturing volume up/down key presses in broadcast receiver?

由 别来无恙 提交于 2019-11-28 01:24:46
I'm trying to make an application where the user can override the default behaviour of the volume up/down buttons (as well as the screen on/off button - is this possible?). Anyways, using some code along the lines of the following I can do this: @Override public boolean onKeyDown(int keyCode, KeyEvent event) { super.onKeyUp(keyCode, event); if ((keyCode == KeyEvent.KEYCODE_VOLUME_UP)) { //this is where I can do my stuff return true; //because I handled the event } return false; //otherwise the system can handle it } But I would like it to be possible even when the application is not open,

Is android.permission.RECEIVE_BOOT_COMPLETED not required?

由 南楼画角 提交于 2019-11-28 01:18:40
问题 Does anyone know why my application still receives the ACTION_BOOT_COMPLETED broadcast even when my app doesn't have the permission android.permission.RECEIVE_BOOT_COMPLETED in the manifest file? I thought it was required but a few tutorials I used also didn't have it. A few did. I use my phone running CyanogenMod for testing but I doubt that matters. LogCat shows my "Notified of boot" log upon each boot. See below for code used. AndroidManifest.xml <receiver android:name="AlarmReceiver">

Getting multiple broadcasts from intents?

由 我与影子孤独终老i 提交于 2019-11-28 01:02:29
问题 http://mobiforge.com/developing/story/sms-messaging-android I used the example code in the above link my own application for sending an SMS, but I run into a problem when checking the sent status of my message. What happens is, the toast message will pop up for every message I have attempted to send. So basically, let's say I've already sent 3 messages. When I go to send my 4th message, the toast message will pop up 4 times. It seems that perhaps the BroadcastReceiver is receiving the same
