I am currently working on an app that uses a broadcastreceiver to check for incoming text messages, but all of the sudden it seems to have stopped working, I even wrote a small test application that, to me at least, seems syntactically correct, but also is not functioning.
Here is the code from the test project:
The manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.AGApplications.test"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon" android:label="#string/app_name">
<activity android:name=".test"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".MsgMon">
<intent-filter>
<action android:name=
"android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.RECEIVE_SMS">
</uses-permission>
<uses-sdk android:minSdkVersion="8" />
</manifest>
The BroadcastReceiver:
package com.AGApplications.test;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class MsgMon extends BroadcastReceiver{
#Override
//Called when new message is received
public void onReceive(Context context, Intent intent) {
Log.d("PHONE", "Message Received");
}
}
And the main activity:
package com.AGApplications.test;
import android.app.Activity;
import android.os.Bundle;
public class test extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
As far as I can tell I'm not doing anything wrong, but obviously I am!
So I discovered the issue. You cannot use "PHONE" as a debug tag. Don't ask me why, as I cannot seem to figure it out, but after using multiple different tags, "PHONE" was the only one that wouldn't register.
My bug seems to lie elsewhere and I am hot on the trail again! Thank you all for your help!
All seems to ok for me i have done same example
here is my code :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.infostretch.broadcastex"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon" android:label="#string/app_name">
<receiver android:name="broadcastex" android:label="#string/app_name"><intent-filter><action android:name="android.provider.Telephony.SMS_RECEIVED"></action>
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
</manifest>
public class broadcastex extends BroadcastReceiver {
/** Called when the activity is first created. */
private static final String TAG = "smsfwd";
private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
public void onReceive(Context context, Intent intent) {
Log.i(TAG, "Intent recieved: " + intent.getAction());
Log.i(TAG, "Message recieved: " + messages[0].getMessageBody());
if (messages.length > -1) {
Log.i(TAG, "Message recieved: " + messages[0].getMessageBody());
}
}
this code is working for me in android 2.1 have a try i think all is same as you

I'm wondering why this simple receiver for detecting connection change don't work for me, it is like with al other sample which i search on google
in this sample application i have only one activity and broadcast
BroadcastReceiver:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class ConnectivityReceiver extends BroadcastReceiver {
public ConnectivityReceiver() {
super();
}
#Override
public void onReceive(Context context, Intent arg1) {
Log.e("onReceive ", " , ");
}
}
manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sample.sampleapp">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<receiver
android:name=".ConnectivityReceiver"
android:enabled="true">
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
</intent-filter>
</receiver>
</application>
</manifest>
after turning on/off i dont have any output on logcat
and its my activity:
public class MainActivity extends AppCompatActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
If your application is targeting Android N, then you must have to register your CONNECTIVITY_CHANGE broadcast dynamically Context.registerReceiver().

Android N Background Optimizations
I've tried:
This which doesn't work on my phone:
Trying to start a service on boot on Android
This which also fails to work properly:
http://www.compiletimeerror.com/2014/12/android-autostart-app-after-boot-with.html#.VpL6sxWLTIU
And a few others which I couldn't find again. Could someone please post a working example of code which will start a MainActivity with the default HelloWorld xml layout?
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<receiver android:name=".MyBroadcastReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<activity
android:name=".MyService"
android:label="#string/title_activity_my_service" >
</activity>
</application>
</manifest>
package com.example;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent startServiceIntent = new Intent(context, MyService.class);
context.startService(startServiceIntent);
}
}
package com.example;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MyService extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_service);
}
}
First：create a BroadcastReceiver, onReceive(Context context, Intent intent)，start the app you want to startup in this method
public class BootBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
xxx.class is the app you want to start
Intent service = new Intent(context,XXXclass);
context.startService(service);
Log.v("TAG", "you want to startup this app.....");
Intent intent = getPackageManager().getLaunchIntentForPackage(packageName);
context.startActivity(intent );
} }
Secondly:configure receiver and intent-filter
<receiver android:name="BootBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"></action>
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</receiver>
THirdly,add permission
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
For my app I use pushbullet to send push messages to my device. On this device, I have an app, that should display this message. Therefore I use the pushbullet - API, described here: https://docs.pushbullet.com/extensions/messaging/guide/
So I add a service to my manifest file and implemented a class, that only should write a Log message.
my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.stfgorbitzapp"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="com.pushbullet.android.permission.READ_MESSAGING_EXTENSION_DATA" />
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:name=".SampleMessagingExtension"
android:permission="com.pushbullet.android.permission.READ_MESSAGING_EXTENSION_DATA">
<intent-filter>
<action android:name="com.pushbullet.android.extension.MessagingExtension" />
</intent-filter>
<meta-data
android:name="protocolVersion"
android:value="1" />
</service>
</application>
</manifest>
my basic activity, only showing "Hello World"
package com.example.stfgorbitzapp;
import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
}
}
my class, that should be executed when receiving the intent:
package com.example.stfgorbitzapp;
import android.content.Intent;
import android.util.Log;
import com.pushbullet.android.extension.MessagingExtension;
public class SampleMessagingExtension extends MessagingExtension{
private static final String TAG = "SampleMessagingExtension";
#Override
protected void onMessageReceived(final String conversationIden, final String message) {
Log.i(TAG, "Pushbullet MessagingExtension: onMessageReceived(" + conversationIden + ", " + message + ")");
}
#Override
protected void onConversationDismissed(final String conversationIden) {
Log.i(TAG, "Pushbullet MessagingExtension: onConversationDismissed(" + conversationIden + ")");
}
}
but when I send a push message, I could not read the Log message. Can onyone help me? Did I forget something? I.e. specific permissions?
Maybe do you need also Network state and Wifi permissions?
Pushbullet should use network to exchange notifications..
About the log: the priority is set to INFO level. Maybe do you filter them?
Do you use Android Studio or Eclipse?
I want to check whether internet is present or no continuously in background service so that I get broadcast as soon as the device gets connected to internet. Suggest with some snippets. Thank you.
Create class that extends BroadcastReceiver , use ConnectivityManager.EXTRA_NO_CONNECTIVITY to get connection info.
Code :
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.widget.Toast;
public class CheckConnectivity extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent arg1) {
boolean isConnected = arg1.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false);
if(isConnected){
Toast.makeText(context, "Internet Connection Lost", Toast.LENGTH_LONG).show();
}
else{
Toast.makeText(context, "Internet Connected", Toast.LENGTH_LONG).show();
}
}
}
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.connect.broadcast"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="8"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<receiver android:exported="false"
android:name=".CheckConnectivity" >
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
</intent-filter>
</receiver>
</application>
</manifest>
Rather than creating Service just create intent-filter with connectivity change Developer Android
<receiver android:enabled="true" android:name=".YourReceiver"
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
</intent-filter>
With your BroadcastReciever:
public class YourReceiver extends BroadcastReceiver
{
#Override
public void onReceive( Context context, Intent intent )
{
}
}
So in my Android app, I've been testing how to detect an incoming and outgoing call. I got it to work by building a class that extends a BroadcastReceiver, but in that class if I call another class it crashes. For example MyClass mc = new MyClass(); mc.functionname();
My actual app is running a looping sound clip. I want to pause that sound clip when an incoming or outgoing call is made. The soundclip is played in a class that extends Activity. How do I do this?
This is what I have for the BroadcastReceiver class and my manifest.
package com.anthony.phone;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;
public class inComingReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle bundle = intent.getExtras();
if(null == bundle)
return;
Log.i("MYTAG",bundle.toString());
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
Log.i("MYTAG","State: "+ state);
if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
{
String phonenumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
Log.i("MYTAG",":) Incomng Number: " + phonenumber);
String info = "Detect Calls sample application\nIncoming number: " + phonenumber;
Toast.makeText(context, info, Toast.LENGTH_LONG).show();
}
}
}
and my manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.anthony.phone"
android:versionCode="1"
android:versionName="1.0" xmlns:android="http://schemas.android.com/apk/res/android">
<uses-sdk android:minSdkVersion="10" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".CallTActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="com.anthony.phone.inComingReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"/>
</intent-filter>
</receiver>
</application>
</manifest>
i had also this kind of problem. i solved by calling activity from broadcast receiver And writing my class code in particular Activity. As mentioned below
Intent i = new Intent(context,newActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
i hope it will help you to solve your query.
ask me if you further have any doubt.
