Android onReceive in BroadcastReceiver not working

I added a receiver to listen when app is installed. But it is not working. Here is my code in AndroidManifest.xml
<receiver android:enabled="true"
android:exported="true"
android:name="com.bsp.iqtest.reiceiver.IQTestReceiver">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_ADDED" />
<action android:name="android.intent.action.PACKAGE_REPLACED" />
<data android:scheme="package"/>
</intent-filter>
</receiver>
Here is my code in MainActivity (launcher activity) , function onCreate.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
IQTestReceiver br = new IQTestReceiver();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED);
intentFilter.addAction(Intent.ACTION_PACKAGE_REPLACED);
intentFilter.addDataScheme("package");
registerReceiver(br, intentFilter);
}
Here is my code in IQTestReceiver (this class is written in other file)
public class IQTestReceiver extends BroadcastReceiver {
public IQTestReceiver() {
}
#Override
public void onReceive(Context context, Intent intent) {
String packageName=intent.getData().getEncodedSchemeSpecificPart();
Log.e("HELLO",packageName);
}
}
I set a breakpoint in onReceive function , but it doesn't run when i debug.
Thanks for your helping.

You can not receive PACKAGE_ADDED or PACKAGE_REPLACED for your own app, if that is what you're trying.
"Broadcast Action: A new application package has been installed on the device. The data contains the name of the package. Note that the newly installed package does not receive this broadcast."
See http://developer.android.com/reference/android/content/Intent.html

set your broadcasrt in manifest like this
<receiver
android:name=".IQTestReceiver"
android:exported="true"
android:enabled="true">
<intent-filter>
<action android:name="check_values"/>
</intent-filter>
</receiver>
and send the broadcast like this.....Intent it1=new Intent(Intent.ACTION_USER_PRESENT);
it1.setAction("check_values");
it1.putExtra("data_key1",message);
sendBroadcast(it1);
and in on receive would be like this....
#Override
public void onReceive(Context context, Intent intent)
{
data1=intent.getStringExtra("data_key1");
System.out.println("ffffff11" + data1);
}

BroadCast receiver on boot

I'm starting with android and I'm having some lessons to learn some android concepts. In this case, I'm practicing with the BroadCast receivers.
I have to create a BroadCast Receiver that when I boot the phone/emulator, starts an activity which shows a plain text.
I have this class:
public class MainActivity extends Activity {
private final BroadcastReceiver receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
IntentFilter mfilter = new IntentFilter(Intent.ACTION_BOOT_COMPLETED);
registerReceiver(receiver, mfilter);
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
But i'm not getting to do what I need, it simply does nothing, so... What I'm doing wrong here?
In the manifest I just have the activity declared.

Try this...
Step1:
set the permission in AndroidManifest.xml
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
Step2:
Add this is intent filter in receiver,
<receiver android:name=".BootReciever">
<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
Step3:
Now you can start your application's first activity from onReceive method of Receiver class..
public class BootReciever extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(context, MainActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(myIntent);
}
}

You can not register ACTION_BOOT_COMPLETED receiver dynamically(it's not a way).
ACTION_BOOT_COMPLETED receiver has to be registered statically in manifest file
ex
<receiver android:name="com.myapp.receiver.BootReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>

When you register a receiver in Activity or in Service it's lifetime is bound with them
You need to define your receiver inside app manifest.
For ex:
Class
class MyClass extends BroadCastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
IntentFilter mfilter = new IntentFilter(Intent.ACTION_BOOT_COMPLETED);
registerReceiver(receiver, mfilter);
}
}

Create your own MyReceiver class by extending BroadcastReceiver class, and register your MyReceiver in the manifest with filter ACTION_BOOT_COMPLETED.
<receiver android:name="com.test.MyReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>

Dynamic register to broadcast receiver not working

When I'm setting my broadcast receiver as anonymous class his never called
but when I'm setting it as class and declare it on android manifest its work fine
i want the ability of register and unregister the broadcast receiver dynamically
why its won't working
here is my code:
public class AppChangedProbe extends Probe.Base implements Probe.ContinuousProbe{
private BroadcastReceiver appReceiver;
#Override
protected void onEnable() {
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_PACKAGE_ADDED);
filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
appReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_PACKAGE_REMOVED))
Logger.i(getClass(), "App Removed");
if (intent.getAction().equals(Intent.ACTION_PACKAGE_CHANGED))
Logger.i(getClass(),"App Updated");
if (intent.getAction().equals(Intent.ACTION_PACKAGE_ADDED))
Logger.i(getClass(),"App Added");
}
};
getContext().registerReceiver(appReceiver, filter);
}
#Override
protected void onDisable() {
getContext().unregisterReceiver(appReceiver);
}
#Override
protected boolean isWakeLockedWhileRunning() {
return false;
}
}
the Probe.Base and Probe.ContinuousProbe are FUNF project jars.
i set this permissions on the manifest:
<uses-permission android:name="android.permission.BROADCAST_PACKAGE_REMOVED" />
<uses-permission android:name="android.permission.BROADCAST_PACKAGE_CHANGED" />
<uses-permission android:name="android.permission.BROADCAST_PACKAGE_ADDED" />
when i use the broadcast receiver as class its work
here is the code that work:
public class AppChangedReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_PACKAGE_REMOVED))
Logger.i(getClass(),"App Removed");
if (intent.getAction().equals(Intent.ACTION_PACKAGE_CHANGED))
Logger.i(getClass(),"App Updated");
if (intent.getAction().equals(Intent.ACTION_PACKAGE_ADDED))
Logger.i(getClass(),"App Added");
}
}
and in the manifest:
<receiver android:name =".sensors.EventBaseProbes.AppChangedReceiver">
<intent-filter android:priority="100">
<action android:name="android.intent.action.PACKAGE_REMOVED"/>
<action android:name="android.intent.action.PACKAGE_CHANGED"/>
<action android:name="android.intent.action.PACKAGE_ADDED"/>
<data android:scheme="package"/>
</intent-filter>
the occurred is that when i use other actions its work in both ways.
for example if i replace the filter on the example to this filter
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
the receiver works fine and get called when the screen is on
are they 2 kinds of action:
1) need to be declared on manifest
2) don't need to be declared on manifest

I have been dealing with the same problem recently. Here is how you should do.
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_PACKAGE_ADDED);
filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
filter.addDataScheme("package");
Since you have <data android:scheme="package"/> inside your AndroidManifest file. You should have it programatically too. Otherwise it won't work.
And lastly, you don't have to add any permission. These Broadcasts doesn't require permission.

How can I track an APK install

I'm trying to track an APK install. When a user lands on the downloadpage (not the store), he is coming from a specific source. When user clicks on download, the APK will be installed. After it's installed, I need to map the install to the source the user was coming from before installing. Is there any good way to do this?
My plan so far: Save the user IP and screen resolutions on the download page to a database. After install, pass IP and screen resolution to the server and map with the row in the database. Is this a good way of doing this?
Hope you guys can help me.

You just need to write a BroadcastReceiver for this which can receive the PACKAGE_ADDED and PACKAGE_INSTALL Intent:
InstallBroadcastReceiver.Class
public class InstallBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if(action.equals(Intent.ACTION_PACKAGE_ADDED)
||action.equals(Intent.ACTION_PACKAGE_INSTALL)){
notifyServerForApplicationInstall(context, intent);
}
}
private void notifyServerForApplicationInstall(Context context,Intent intent){
//send the data to your server here
}
}
Register the receiver in AndroidManifest file
<receiver
android:name=".InstallBroadcastReceiver"
android:exported="false"
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.PACKAGE_ADDED" />
<action android:name="android.intent.action.PACKAGE_INSTALL" />
<data android:scheme="package" />
</intent-filter>
</receiver>
Don't forget to give this permissions in manifest :
<uses-permission android:name="android.permission.INSTALL_PACKAGES"/>

I have prepared a BroadcastReceiver class :
public class newPackageReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("DEBUG"," test for application install/uninstall");
}
}
In the main activity, I first register a new receiver object, then instanciate button for application install.
public void onCreate(Bundle savedInstanceState) {
...
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_PACKAGE_ADDED);
filter.addAction(Intent.ACTION_PACKAGE_CHANGED);
filter.addAction(Intent.ACTION_PACKAGE_DATA_CLEARED);
filter.addAction(Intent.ACTION_PACKAGE_INSTALL);
filter.addAction(Intent.ACTION_PACKAGE_REMOVED);
filter.addAction(Intent.ACTION_PACKAGE_REPLACED);
filter.addAction(Intent.ACTION_PACKAGE_RESTARTED);
receiver = new newPackageReceiver();
registerReceiver(receiver, filter);
...
dlButton.setText(R.string.dl_button);
dlButton.setOnClickListener(new AppliDownloadOnClickListener(this ));
#Override
public void onDestroy(){
unregisterReceiver(receiver);
super.onDestroy();
}

My Broadcast receiver get execute even if my application is not working

My broadcast receiver is Still getting execute even if My application is not working.
as an example I am using android.intent.action.NEW_OUTGOING_CALL to check outgoing call and than i stop music and push notification ..
but even i close my app and kill all task and after if i call than i get notification of my app..
So how do i manage to work my broadcast when i am using my app.
I have crated Service to play music and 2 broadcast receiver file for incoming and outgoing.
Help to solve this problem.
Also How can i destroy my app with service running behind If user press exit button.
**Update I made edited it and its working now fine..thank you so much you all
here is my code
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main"
android:launchMode="singleTask">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="OutgoingCallInterceptor">
<intent-filter android:priority="1">
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
<receiver android:name="IncomingCallInterceptor">
<intent-filter android:priority="1">
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="android.media.AUDIO_BECOMING_NOISY" />
</intent-filter>
</receiver>
Update
as you all suggest me i have made receiver into main class file and register it from there but it wont work
public class MainActivity extends Activity {
RemoteViews layout;
int SDK_INT;
BroadcastReceiver br;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
IntentFilter filter = new IntentFilter("android.media.AUDIO_BECOMING_NOISY");
this.registerReceiver(br, filter);
setContentView(R.layout.activity_main);
SDK_INT = android.os.Build.VERSION.SDK_INT;
System.out.println(SDK_INT);
Button start = (Button)findViewById(R.id.play);
Button stop = (Button)findViewById(R.id.stop);
start.setOnClickListener(startListener);
stop.setOnClickListener(stopListener);
br = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
if (intent.getAction().equals(android.media.AudioManager.ACTION_AUDIO_BECOMING_NOISY)) {
context.stopService(new Intent(context, myPlayService.class));
Toast.makeText(context, "Headphones disconnected.", Toast.LENGTH_SHORT).show();
}
} }
};
#Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(br);
}

an example: how a broadcast reciver can be registered and un registered change as per your need "i hope the code is self explanatory"
private final BroadcastReceiver xyz= new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
//ur reciver
}
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
IntentFilter filter = new IntentFilter(ACTION);//ur action
this.registerReceiver(xyz, filter);
}
#Override
protected void onDestroy(){
super.onDestroy();
unregisterReceiver(xyz);
}

You need to declare unregisterReceiver() in onResume() or in onpause() methods.
This will solve your problem.

First:
use unregisterReceiver() in onPause() and re-register in onStart().
It's always better to have locally registering the receiver if you want to provide the functionality only when your app is up.
Second:
Use service after binding it and don't call unBind while exiting the app will keep your service alive even after your app is down. I guess you are starting the service locally. Start service by binding it.
Hope this will solve your problem.
