Android - make programmatically created broadcast receiver exported

I am trying to make my receiver that I statically defined in the manifest dynamic by creating it programmatically.
That's the static version in the manifest:
<receiver android:name=".receivers.PackageReceiver" android:enabled="true" android:exported="true">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_ADDED" />
<action android:name="android.intent.action.PACKAGE_REMOVED" />
<action android:name="android.intent.action.PACKAGE_CHANGED" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="package" />
</intent-filter>
</receiver>
That's how I did it in code:
val intentFilter = IntentFilter()
intentFilter.addAction(ACTION_PACKAGE_ADDED)
intentFilter.addAction(ACTION_PACKAGE_REMOVED)
intentFilter.addCategory(CATEGORY_DEFAULT)
intentFilter.addDataScheme("package")
registerReceiver(PackageReceiver(), intentFilter)
The programmatic version is not triggered when a package is installed/uninstalled whereas the static one is. I figure it's because the first version is exported - how can I achieve this in code?

Send a mobile number from default android dialer to my application

I have a application for calling an API for phone call,
When a user dials a number from default dialer of android phone, the number should be copied into the second app(free call twilio),shown in picture.
Here is what I tried, but no luck.
<activity
android:name=".MainActivity"
android:screenOrientation="portrait"
android:theme="#android:style/Theme.NoTitleBar" >
<intent-filter>
<action android:name="android.intent.action.CALL_BUTTON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.CALL_PRIVILEGED" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="tel" />
</intent-filter>
</activity>
Can anyone help please? :-)

please use below code
Register a BroadcastReceiver like this in Manifest file:
<!-- DIAL Receiver -->
<receiver
android:exported="true"
android:name="receivers.DialBroadcastReceiver" >
<intent-filter >
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
You need Permission for NEW_OUTGOING_CALL :
<!-- OUTGOING CALL PERMISSION-->
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
public class DialBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.v("DileBroadCastReceiver","In onReceive()");
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.v("DialBroadcast Receiver","Number is: "+number);
}
}
}

I think you forgot to add intent-filter in your mainActivty like below
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
also add your existing intent-filter as well. Gud luck

It can be possible after searching a lot in google. Finally I got an answer I am sharing it for others.
It can be possible by adding following intent filter in manifest file.
<intent-filter>
<action android:name="android.intent.action.CALL_BUTTON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

create a broadcast reciever with android.intent.action.NEW_OUTGOING_CALL and then call
dialledNumber=intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
This will give you outgoing number
try this.it might help
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber));
callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(callIntent);

Cannot receive Uninstall broadcast

I am trying to detect the uninstall action of my application. Till now, I have got a specific code that catch the uninstall action and inflate an Activity. Here is the code:
Manifest:
<activity
android:name=".UninstallActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.DELETE" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="package" />
</intent-filter>
</activity>
I have created a simple Activity called UninstallActivity and It works fine. When the user try to uninstall the app this Activity has been inflated.
I am trying to listen on those intents with a Receiver instead of Activity but I have failed to get this action. My code is:
Manifest:
<receiver android:name=".PackageUninstallReceiver" >
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.DELETE" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="package" />
</intent-filter>
</receiver>
PackageUninstallReceiver:
public class PackageUninstallReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("uTag", "In the PackageUninstallReceiver onReceive()");
if (intent.getAction().equals(Intent.ACTION_DELETE) && intent.getDataString().contains(context.getPackageName())) {
Log.d("uTag", "Uninstallation is being happened....");
}
}
}
First, is it possible to listen to this Intent with the receiver?
If yes, what is wrong with my code?

The Intent used to start an Activity (in this case, an Intent to VIEW or DELETE a PACKAGE) is a completely different thing from a braodcast Intent. They share some of the same properties, but are still completely different things. a broadcast Intent will never start an Activity and an Intent used to start an Activity will never be seen by a BroadcastReceiver.
Therefore, the answer to your question
First, is it possible to listen to this Intent with the receiver?
is "no".

The actions you are listening are generic and could be applied in any context with a different schema. What you should be listening to is the package changing.
<receiver android:name="PackageChangeReceiver">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_ADDED"/>
<action android:name="android.intent.action.PACKAGE_REPLACED"/>
<action android:name="android.intent.action.PACKAGE_REMOVED"/>
<data android:scheme="package"/>
</intent-filter>
</receiver>

Android Notification App

I'm currently working on an android application. I have to log any new installed app name whenever the user is installing/downloading a new third party app. How can I get the notification if the user is installing a new app. Thanks in advance.
Java File
public class ApplicationBroadcastService extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
System.out.print("-------");
}
}
Manifest
<receiver android:name=".applicationlog.ApplicationBroadcastService">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_ADDED" />
<action android:name="android.intent.action.PACKAGE_CHANGED" />
<action android:name="android.intent.action.PACKAGE_INSTALL" />
<action android:name="android.intent.action.PACKAGE_REMOVED" />
<action android:name="android.intent.action.PACKAGE_REPLACED" />
</intent-filter>
</receiver>
But still I do not enter the onReceive method, when I am installing/uninstalling any app.
Here is the solution:
I did a small change in my Manifest file.
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.PACKAGE_ADDED" />
<action android:name="android.intent.action.PACKAGE_CHANGED" />
<action android:name="android.intent.action.PACKAGE_INSTALL" />
<action android:name="android.intent.action.PACKAGE_REMOVED" />
<action android:name="android.intent.action.PACKAGE_REPLACED" />
<data android:scheme="package" />
</intent-filter>
Now it's working fine.. :)
Thanks again #willytate

Ajay,
You will need to setup a BroadcastReceiver with an intent filter to receive the following Action: ACTION_PACKAGE_ADDED then from the onReceive() method of the BroadcastReceiver you can launch a Notification.

Take a look at the intent documentation. You are looking for ACTION_PACKAGE_INSTALL (which seems to be never used, see comments) and ACTION_PACKAGE_REMOVED.

You can listen for the android.intent.action.PACKAGE_ADDED intent.

Can't receive broadcasts for PACKAGE intents

I am trying to register a Broadcast Receiver to receive broadcast events for the package events. Following is the code and my receiver in the manifest file. The log statment never happens, but I can clearly see the same broadcast firing for "HomeLoaders" (the Launcher) debug statements. What am I missing?
public class IntentListener extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Log.i("INTENT LISTNER:", intent.getAction());
}
}
<receiver android:name="IntentListener" android:enabled="true" android:exported="true">
<intent-filter>
<data android:scheme="package"></data>
<action android:name="android.intent.action.PACKAGE_ADDED"></action>
<action android:name="android.intent.action.PACKAGE_ADDED"></action>
<action android:name="android.intent.action.PACKAGE_CHANGED"></action>
</intent-filter>
</receiver>

It is possible that these Intents cannot be received by components registered in the manifest, but only by receivers registered in Java via registerReceiver().

These three intents namely,
Intent.ACTION_PACKAGE_ADDED
Intent.ACTION_PACKAGE_REMOVED
Intent.ACTION_PACKAGE_CHANGED
when broadcasted by the system, have
Intent.FLAG_RECEIVER_REGISTERED_ONLY_BEFORE_BOOT
flag added so that only the registered receivers will receive the broadcasts and no broadcast receiver components will be launched. Refer Intent and PackageManagerService class of source for further details.

This is my manifest, without
<category android:name="android.intent.category.DEFAULT" />
My app detects only the Android Market app install, but does not remove. Now it receives also the non-Android Market app broadcasts.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:label="#string/app_name"
android:name=".SomeActivity" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="com.som.pakage.PackageInstallReceiver" >
<intent-filter >
<action android:name="android.intent.action.PACKAGE_ADDED" />
<action android:name="android.intent.action.PACKAGE_REMOVED" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="package" />
</intent-filter>
</receiver>
</application>
