I created my broadcast receiver AnprEventReciever that should be triggered when connectivity state changes, however it doesn't.
AnprEventReciever:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
import bi.anpr.layouts.SplashActivity;
public class AnprEventReciever extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.e("test","event recieved");
Toast.makeText(context, "event recieved" , Toast.LENGTH_LONG).show();
}
}
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Please note that i'd tested almost every possible action that all failed except the BOOT_COMPLETED, where my BroadcastReceiver was successfully fired.
Thanks for #TheWanderer who helped me through his comment to find the answer. In the Android 8.0 Behavior Changes Note developers mentioned the following:
Apps cannot use their manifests to register for most implicit
broadcasts (that is, broadcasts that are not targeted specifically at
the app).
So i tried to programatically registering my BroadcastReceiver like this below instead of creating a manifest entry for it:
private AnprEventReciever myReceiver;
private IntentFilter filter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video_resource);
filter = new IntentFilter();
filter.addAction(Intent.ACTION_AIRPLANE_MODE_CHANGED);
myReceiver = new AnprEventReciever();
}
#Override
protected void onResume() {
super.onResume();
registerReceiver(myReceiver, filter);
}
#Override
protected void onPause() {
super.onPause();
unregisterReceiver(myReceiver);
}
It works perfectly, however unfortunately the action "android.intent.action.CONNECTIVITY_CHANGE" seems to be deprecated where i couldn't find it in the Intent class and i don't know if it is found elsewhere.
Note: as i go through reading i found that it is necessary to un-register the broadcast receiver when the activity pauses or destroys, otherwise you might get an error when trying to register or re-register it.
UPDATE:
Create intent filter with ConnectivityManager.CONNECTIVITY_ACTION instead of "android.intent.action.CONNECTIVITY_CHANGE" in order to receive connectivity changed broadcasts.

I've seen a lot of question like this around and I've tried a bunch of things without success...
I just want to log a sms received using a subclass of BroadcastReceiver like I've seen in so many tutorial...
so here is my code and config
BroadcastReceiver
package com.example.koki.mysms;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class SmsReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("MainActivity", "test");
Toast.makeText(context, "ON RECEIVE BROADCAST", Toast.LENGTH_LONG).show();
}
}
there's nothing in my MainActivity beside what you get when creating a new projet with android studio.
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>

the way I test it (not very familiar in android development yet), is that I have two emulator and I sent sms to one another. They both receive the sms but nothing in the logcat nor the Toast appear. what am I doing wrong?
Hello fellow programmers,
I cant find a proper way to route my application, I would like one file to decide which activity has to be started
I am building an android application that in general contains:
-2 ways to start up
-3 activity's
The application can be launched by clicking the icon (standard launch)
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
And an activity is started when there is an incoming call
<action android:name="android.intent.action.PHONE_STATE" />
In the first setup there was 2 activity's one to register and one to use the application. In this
setup I added an extra activity to check if a token was present and route to the right activity.
In the setup that I have now, all the actions are in the of a broadcast receiver. I tried implementing the logic of the extra activity.
The problem I am facing is the check of the incoming call, it is always launching the same activity CallHandler,
I think routing the application within a broadcast receiver might be bad practice, but I can not find a better way of routing the application, and the current code does not work.
Your help is very much appreciated, the following pieces of code might help explain my issue:
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<receiver android:name=".RoutingCallReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</receiver>
<activity

</activity>
<activity
android:name=".CreateCallActivity"
android:label="#string/title_activity_create_call" >
</activity>
</application>
RoutingCallReceiver:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
public class RoutingCallReceiver extends BroadcastReceiver {
TelephonyManager telephony;
Intent in;
public void onReceive(Context context, Intent intent) {
PrimePhoneStateListener phoneListener = new PrimePhoneStateListener();
telephony = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
if(telephony.getCallState()== 1){
in = new Intent(context, CallHandler.class);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(in);
}
else {
TokenIO tokenHandler = new TokenIO();
String token = tokenHandler.getToken(context);
Log.d("AAfter", "Token");
if(token.equals("") || token.equals(null)){
in = new Intent(context, RegisterActivity.class);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(in);
}
else{
in = new Intent(context, CreateCallActivity.class);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(in);
}
}
}
// when finish your job, stop listen to changes
public void onDestroy() {
telephony.listen(null, PhoneStateListener.LISTEN_NONE);
}
}
you can make change in your xml file
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<receiver android:name=".RoutingCallReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
<activity
android:name=".RegisterActivity"
android:label="#string/app_name"
android:windowSoftInputMode="adjustResize|stateVisible" >
</activity>
<activity
android:name=".CallHandler"
android:label="#string/title_activity_main" >
</activity>
<activity
android:name=".CreateCallActivity"
android:label="#string/title_activity_create_call" >
</activity>
</application>
and put this tag into main activity
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
and i hope that will work fine.
i'm having trouble with the auto-start feature of my APP.
I've searched trhough the forums, seen many suggestions, none seems to work and I don't know why.
Here's the BootUpReciver.java
package com.???.???;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class BootUpReciver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
//Intent pushIntent = new Intent(context, BackgroundService.class);
//context.startService(pushIntent);
Toast.makeText(context, "Device Booted", Toast.LENGTH_LONG).show();
Log.d("TAG","Device Booted");
}
}
}
And here's my Manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.???.???"
android:versionCode="1"
android:versionName="1.0" >

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="17" />
<application
android:theme="#android:style/Theme.Holo"
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<receiver android:name=".BootUpReciver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
<activity
android:name="com.???.???.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>
</application>
When i restart my phone i don't even see the Toast, why? what should i do? I need to auto-start to get some sharedprefs and write a value to a file every boot.
Thanks.
While testing I found that If I show toast in onReceive then it is not showing. But if I start an activity in onReceive then it is working. So you can also check this. Start an activity or service and perform your task there.
I am trying to get my app to auto start on boot up and it will and an error occurs while launching the application
Here is my manifest and the program file for the "Auto Starter":
manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="this.bad.file"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name="autoBot"
android:enabled="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
Here is the "AutoBot" as I have called it (Not for spammy reasons I just like transformers):
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class autoBot extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Intent startUp = new Intent(context, MainActivity.class);
context.startActivity(startUp);
}
}
So there we have it!
In your manifest, you left out a vital name of the class, usually, can be abbreviated to [dot][ClassName] or the full package name, as in for example .autoBot or see the example below:
<receiver android:name="this.bad.file.autoBot">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
And in your Broadcast receiver:
public class autoBot extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent startUp = new Intent(context, MainActivity.class);
context.startActivity(startUp);
}
}
Notice the usage of #Override on the onReceive class.
The normal recommended route to take is usually, to start an alarm on boot, and listen for the broadcast when the alarm has expired, in that way your activity does not hog up the boot and also, allow the boot up process to "settle" for a bit.
I have some problem with BroadcastReceiver. There nothing happens when I catch an outgoing call.
public class demoBroadcastReceiver extends BroadcastReceiver {
/** Called when the activity is first created. */
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(context, "there is new calling", Toast.LENGTH_LONG).show();
}
}
This is content of my Manifest:
<uses-sdk android:minSdkVersion="7" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<receiver android:name=".demoBroadcastReceiver">
<intent-filter >
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
<intent-filter >
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
</application>
</manifest>
Updated:
Thanks Lucifer for solution:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED">
I also need this:
<uses-permission android:name="android.permission.NEW_OUTGOING_CALL" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />**strong text**
You should declare this permission in your AndroidManifest.xml file
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
maybe you should post your log here, so we can analyse it.
try add this permission:
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
Hope this
put this in your manifest
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
and this in your application node..
<receiver android:name="com.example.demoBroadcastReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" /> <--- add this intent filter
</intent-filter>
</receiver>
this is to start a service when a device boots up on android
