I am writing an application to listen the SMS inbox in android with one activity and one BroadcastReceiver. Once the SMS comes the Receiver is showing alert message. But I want to send the message information from Receiver to Activity. I don't know how to achieve this.

trying to create a broadcast receiver which responds to system events and change system settings. I don't need any interaction from the user so I don't need an activity and have been trying to do everything through the manifest file. I've put a log event into my onReceive method but it never logs anything so I'm presuming my method is never called. I've tried this with both the 1.5 and 1.6 SDKs. I was hoping somebody could have a look at my code please and let me know if there are any problems.
View 2 Replies View RelatedI basically want to make and intent and pass to a service from my BroadcastReceiver's onReceive(). So far I always used View.getContext(), but here, I'm stuck. How exactly can I get the context so I can use public Intent (Context packageContext, Class<?> cls). Or is there any other way I can create an Intent and send to a service?
View 1 Replies View RelatedA WAP PUSH (Broadcast)receiver basically doesn't need any UI. It is a silence application which handles the Push messages based on actions/ mimetype without needing any intreaction with user, I've tried to test it in a SMS receiver by removing the Activity from the project and it stopped receiving the SMS messages. My question: Does all android applications "MUST" define a activity? Is there a way to hide it?

View 3 Replies View RelatedI got a graphical problem regarding the Translucent theme at Samsung Galaxy i9000.It works well in the emulator with android version ranging from 1.6 to 2.2 as well as on SE x10 mini.I have yet to test on more devices.I am starting an activity from a broadcast receiver. The activity started got the theme @android:style/Theme.Translucent If all the activities in my application are destroyed when the broadcast occurs, then the new activity got a working translucent theme and is presented on top of the activity currently in front. However, if the user left the application with the HOME-key, not destroying the activity, I get a graphical bug when the broadcast triggers. The application gets brought to the front with the activity the user last visited showing instead of the new activity that I started from my broadcast receiver. When I press the back key I can see my Translucent activity quickly showing itself and then getting destroyed.This flow results in the graphical bug: Start application. Activity A will be shown. Leave application by pressing HOME-key. Home screen is shown. Trigger broadcast. Start activity B.
Application gets brought to foreground and activity A is shown. Press BACK-key. Activity B quickly shows itself and disappears. Now activity A is shown.Also, after activity B is started and when activity A is shown in its place. Pressing the screen will triggers buttons that belong in activity B even if the user can't see them. If I remove the theme, then activity B will show itself when it's supposed to.Is there anyone else who have encountered a similar problem? Is there any good workarounds I can apply? (I don't want to rebind home to finish all activities) Is the problem my fault or can there possibly be some glitch in Touchwiz?
I have a single Activity application, within it I have a service which creates an AlarmManager and sends a broadcast to a broadcast Receiver.If the activity which starts the services dies, (ie. divide by zero), the broadcast receiver stops the old service which created the AlarmManager.It works the first time. The second time, it does not.It seems like the AlarmManager is still active but the broadcast receiver is no longer receiving. It works great once!

I am adding some basic alarm functionality to my program via the use of AlarmManager and a BroadcastReceiver class (named AReceiver.java). My problem is that the data I add to the bundle attached to the Intent creating the PendingIntent appears to be lost. The only bundle data I can access in the AReceiver class is a android.intent.extra.ALARM_COUNT=1. Here is the basic code in the main activity class creating the Intent, PendingIntent and the AlarmManager: [Code in main activity - Notepadv3]
Intent intent = new Intent(Notepadv3.this, AReceiver.class);
intent.putExtra("teststring","hello, passed string in Extra");
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, pendingPeriodIntentId, intent, 0);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, timeOfNextPeriod.getTimeInMillis(), alarmIntent);..................
I have been trying to get this program to work but so far having no luck. I cannot find where I am doing wrong. I'm not sure if there's something wrong with the code, or debugging.
Here is my program:
package Technicaljar.SMSBroadcastReceiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
public class SMSBroadcastReceiver extends BroadcastReceiver {
private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
private static final String TAG = "SMSBroadcastReceiver";
@Override
public void onReceive(Context context, Intent intent) {
Log.i(TAG, "Intent received: " + intent.getAction());
if (intent.getAction() == SMS_RECEIVED) {
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[])bundle.get("pdus");
final SmsMessage[] messages = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
messages[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
} if (messages.length > -1) {
Log.i(TAG, "Message recieved: " + messages[0].getMessageBody());
} } } } }
And the manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="Technicaljar.SMSBroadcastReceiver"
android:versionCode="1"

I am sending SMS through Telnet, and I cannot see any Intent received messages in the logcat. Here is my logcat from the time of installation.

So the SMS seems to be received by the emulator, but looks like the no intents are firing.
What am I doing wrong here? After installing, do I have to somehow 'start' this receiver?
Because when I install, I get
[2010-11-07 21:24:41 - SMSBroadcastReceiver] No Launcher activity found!
[2010-11-07 21:24:41 - SMSBroadcastReceiver] The launch will only sync the application package on the device!
I know that the apps receive a ACTION_SHUTDOWN broadcast event when the device is shutting down.
When an application receives the shutdown, is there still an opportunity to send data packets out, or does android block such attempts(or does the platform tear down the network stack before it can go out).
I am trying to start TTS from a broadcast receiver and it as document an intent receiver can't bind the service. Is there a work around, I can't figure out how to start the service using startService(Intent, Bundle).

View 5 Replies View RelatedI am making a widget that needs a broadcast receiver, like the one in com.example.android.apis.appwidget.ExampleBroadcastReceiver. However, the example defines Intent.ACTION_TIMEZONE_CHANGED in the manifest, but there are some that do not allow this. For example, Intent.ACTION_TIME_TICK says "You can not receive this through components declared in manifests, only by exlicitly registering for it with Context.registerReceiver(). "
So I removed the manifest declarations and tried replacing the AppWidgetProvider.onEnabled function that was in the example with a call like the following: context.registerReceiver(myReceiver, new IntentFilter(Intent.ACTION_TIME_TICK));
(where "myReceiver" is an instance of the receiver I want.) However, when I try to run the code, I get the following error:
Unable to start receiver...android.content.ReceiverCallNotAllowedException: IntentReceiver components are not allowed to register to receive intents.
Any way to get this broadcast receiver working from a widget?
I am broadcasting an Intent from an activity. Can we make another application as a receiver. So that it will get invoked when that specific intent is broadcasted.
View 2 Replies View RelatedI wish to listen to android.intent.action.BOOT_COMPLETED. However I am not getting the broadcast intent, if I specify com.test.BootBroadcastReceiver in the manifest. When I change this value to simply BootBroadcastReceiver, then I am getting the broadcast intent.
<receiver android:name="BootBroadcastReceiver" android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />

My package in the manifest file is:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

And the BootBroadcastReceiver resides in this package. What is the reason behind this?
I have an application that uses an extended Broadcast Receiver class inside the Activity. I have the extended Broadcast Receiver class as a member variable of the Activity class.

View 3 Replies View RelatedI was wondering if its possible to have a broadcast receiver to listen when the app its in launches.I tried doing by creating a BroadcastReceiver to listen for the android.intent.action.MAIN action but it never gets called?Is there something I need to do or a different action I should be listening for?
View 3 Replies View RelatedI have here two applications in two different projects in eclipse. One application
(A) defines an activity
(A1) which is started first. Then i start from this activity the second activity

(B). This works fine.
Unfortunately, the message is never received. Although the method in activity A1 is called, i never receive an intent in B1.
I created a BroadcastReceiver and configured it with an android.provider.Telephony.SMS_RECEIVED action filter so it is called everytime the phone receives a text.Is there some event/action or other way for my application to be notified whenever the phone sends a text (preferably independent of the application that sends it)?So far the only option I see is to poll the content provider for content://sms/sent which doesn't even give me all sent texts because applications can choose not to put it there.
View 1 Replies View RelatedThe symptom: I have a broadcast receiver that listen to sms, when a sms is received, i call an activity to display. It works all fine if the screen is on and not locked. But when screen is locked, and as soon as i received the sms, the activity popup for a second then disappeared and I use the code to unlock the screen.
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
I think it might be the competitions with phone default sms program (the sms default program shows a notification only). I am wondering is there a way to set priority to broadcast receivers or even the activity that receiver stared, to avoid the conflicts between multiple receivers. or set orders to execute one by one? I have tried to thread.sleep my receiver for a second, still not working.
I need to be able to handle/catch Intents while my Activity is closed. So I am looking at either a Service or a BroadcastReceiver. Is it possible to "receive" intents to a service itself? I tried to search, but could not find anything helpful. With a BroadcastReceiver, I am not exactly sure how that works outside of an Activity. Does it depend on the Activity being open/running? Can it run by itself?
Let's say that my Activity is killed by Android(or a task killer app), does the BroadcastReceiver still receive intents and process them? I have used a BroadcastReceiver as a widget, but I do not want to use a widget this time. My goal is to have the user open the Activity to set some options. From there, they would be able to close the Activity, but I would still be able to process Intents that were sent out by the system. I am still fairly new to Android development, so I could be so far away from where I need to be.
I'm trying to receive SMS using broadcast receiver. MySMSReceiver :
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;

/** Tag string for our debug logs */
private static final String TAG = "MySmsReceiver";
@Override
public void onReceive(Context context, Intent intent) {
Log.i(TAG, "Recieved a message");
Bundle extras = intent.getExtras();
if (extras == null)
return;
Object[] pdus = (Object[]) extras.get("pdus");
for (int i = 0; i < pdus.length; i++) {
SmsMessage message = SmsMessage.createFromPdu((byte[]) pdus[i]);
String fromAddress = message.getOriginatingAddress();
String fromDisplayName = fromAddress;
Log.i(TAG, fromAddress);
Log.i(TAG, fromDisplayName);
Log.i(TAG, message.getMessageBody().toString());
break; } } }
and added in Mainfest file
<receiver android:name=".MySmsReceiver" android:enabled="false">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>

Here com.callhandller is my application package where I have Receiver...
So, I added the receiver (contained in application) in the manifest. Broadcast doesn't fire my broadcast receive.
<receiver android:name="mypkg.IncomingCallReceiver">
<intent-filter>
<action android:name="android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED"/ >
</intent-filter>
I am trying to understand the use of the broadcast receiver and the way of activate it. There's two ways isn't it? Register it from an activity or declare it in the manifest. So my question is: If I code a broadcast receiver which is watching incoming messages and I register it in the manifest, when a message comes my broadcast receiver will catch it automatically although any activity of my app had registered it. In a nutshells, I don't have to activate it so it works, only register it either in the manifest or in an activity.
