    text
    copied!<p>I try to enable and disable a broadcast receiver by using this PackageManager method:</p> <pre><code>setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); </code></pre> <p>The broadcast receiver is registered in the manifest. The receiver works fine but when i try to disable it, it still receives the broadcast messages. When i disable the receiver in the manifest by "android:enabled="false"", the receiver does not receive anything but I can not enable it.</p> <p>I call the method from inside a service.</p> <pre><code> PackageManager pm = getApplicationContext().getPackageManager(); ComponentName componentName = new ComponentName("com.app", ".broadcast_receivers.OnNetworkChangedReceiver"); pm.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); </code></pre> <p>Android manifest:</p> <pre><code> &lt;receiver android:name=".broadcast_receivers.OnNetworkChangedReceiver" android:enabled="true"&gt; &lt;intent-filter&gt; &lt;action android:name="android.net.conn.CONNECTIVITY_CHANGE"/&gt; &lt;/intent-filter&gt; &lt;/receiver&gt; </code></pre> <p>The Receiver</p> <pre><code>public class OnNetworkChangedReceiver extends BroadcastReceiver { private static final String TAG = "OnNetworkChangedReceiver"; @Override public void onReceive(Context context, Intent intent) { Log.d(TAG, "in OnNetworkChanged"); } } </code></pre> <p>I also called the method from inside an Activity yesterday. I thought it worked but today nothing works anymore. Could it be that there is sometimes a big delay in the intent (android.net.conn.CONNECTIVITY_CHANGE) that I misinterpreted yesterday as disabling the receiver?</p> <p>Is the approach with the PackageManager the right direction or is there a basic error in the idea?</p> <p>Thanks a lot, Sven</p>
