You should use unregisterReceiver(BroadcastReceiver receiver) in your onPause() to unregister the Broadcast receiver. 

Example:

<pre><code>public class MyActivity extends Activity {
 private final BroadcastReceiver mybroadcast = new SmsBR();

 public void onResume() {
 super.onResume();

 IntentFilter filter = new IntentFilter();
 filter.addAction("android.provider.Telephony.SMS_RECEIVED");
 registerReceiver(mybroadcast, filter);
 }

 public void onPause() {
 super.onPause();

 unregisterReceiver(mybroadcast);
 }
}
</code></pre>

blocks|key|2485389|text|除了在应用程序类中使用广播接收器之外，您还可以在所有活动中使用基类。并在Base活动中注册BR，然后向childs提供回调。由于活动具有严格的生命周期模型，所以在活动中使用运行时广播接收器比在应用程序类中使用更好。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2485390|+public+class+BaseActivity+extends+AppCompatActivity+{

Except using Broadcast Receiver in Application class you can Use a Base class for all your Activities. And register BR in the Base Activity then provide call backs to the childs.
As Activity has a strict lifecycle model so its better to use Runtime Broadcast receivers in Activity rather than Application class .

<pre><code> public class BaseActivity extends AppCompatActivity {
 @Override
 protected void onResume() {
 super.onResume();
 //registerReceiver Here
 }

 @Override
 protected void onPause() {
 super.onPause();
 //unregisterReceiver here
 }
}
</code></pre>

One suggestion is in your launcher activity or desired activity unregister that like this:

<pre><code>@Override
protected void onDestroy() {
 super.onDestroy();
 ((MyApplication) getApplication()).unregisterReceiver();
}
</code></pre>

And implement <code>unregisterReceiver</code> method in <code>MyApplication</code> class:

<pre><code>public void unregisterReceiver() {
 unregisterReceiver(br);//your broadcast
}
</code></pre>

I think you should use <code>LocalBroadcastManager</code> to register and unregister receiver instead of <code>BroadcastReceiver</code>.

<a href="https://developer.android.com/reference/android/support/v4/content/LocalBroadcastManager.html" rel="nofollow noreferrer">Benefits to use LocalBroadcastManager</a>

<pre><code>@Override
public void onCreate(Bundle savedInstanceState) {

 LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
 new IntentFilter("custom-event-name"));
}

@Override
protected void onDestroy() {
 // Unregister since the activity is about to be closed.
 LocalBroadcastManager.getInstance(this).unregisterReceiver(mMessageReceiver);
 super.onDestroy();
}

Try with below code : 
 if you have registered from Manifiest.xml

<pre><code>ComponentName component = new ComponentName(context, MyReceiver.class);

 int status = context.getPackageManager().getComponentEnabledSetting(component);
 if(status == PackageManager.COMPONENT_ENABLED_STATE_ENABLED) {
 context.getPackageManager().setComponentEnabledSetting(component, PackageManager.COMPONENT_ENABLED_STATE_DISABLED , PackageManager.DONT_KILL_APP);
 }
</code></pre>

If programmatically registering reciever : 

<pre><code>@Override
public void onCreate(Bundle savedInstanceState) {

 LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
 new IntentFilter("custom-event-name"));
}

@Override
protected void onDestroy() {
 // Unregister since the activity is about to be closed.
 LocalBroadcastManager.getInstance(this).unregisterReceiver(mMessageReceiver);
 super.onDestroy();
}
</code></pre>

I use Application.ActivityLifecycleCallbacks, that listen all callbacks from activities lifecycle. It can replace the suggestion to use a Base Activity using inheritance and in other hand use composition to resolve this problem.
You implement <code>Application.ActivityLifecycleCallbacks</code> interface in a class and in on create from your application class register the callback as continue:
<pre><code>registerActivityLifecycleCallbacks(&lt;here your typed class with ActivityLifecycleCallbacks&gt;)
</code></pre>
Then, you have full control over al activities lifecycle to do something like unregister or register receivers.
I hope it can be helpful

As @Naruto Uzumaki mentioned above you can deregister it on the <code>onDestroy</code> method of Application.
But it's always a better option to use Broadcast Receiversin Activity instead of whole Application.
You can use the below approach to use it in Activity:-
<pre><code>public class DetailsActivity {

private BroadcastReceiver mNetworkReceiver;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 mNetworkReceiver = new NetworkReceiver();
 registerReceiver(mNetworkReceiver, new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
 }
</code></pre>
Here is the way to unregister it.
<pre><code> @Override
 protected void onDestroy() {
 super.onDestroy();
 unregisterNetworkChanges();
 }

 protected void unregisterNetworkChanges() {
 try {
 unregisterReceiver(mNetworkReceiver);
 } catch (IllegalArgumentException e) {
 e.printStackTrace();
 }
 }
</code></pre>

I register broadcast receiver in Android's Application Class,but now my question is where to unregister that broadcast ?

<pre><code>public class MyApplication extends Application 

{

@Override
public void onCreate() {
 ..... 
 // OTHER INITIALIZATIONS
 initNetworkBR();
} 
private void initNetworkBR() {

 br = new BroadcastReceiver() {
 ....
 };
 IntentFilter filter = new IntentFilter();
 filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
 registerReceiver(br, filter);
 }
}
</code></pre>
