How to pause the current activity when internet connection is not available in android app

Question

My android app requires internet connectivity. I have used broadcastreceiver to monitor the status of network connectivity. But, how do I pause the activity when the network connectivity goes off?

Answer 1

If you get the status of the network connectivity, when it is not connected just call your Activity's onPause method?

public void onPause() {
    super.onPause();
    //pause anything else
}

then call onResume when you have network again?

public void onResume() {
    super.onResume();
    //resume application
}

Answer 2

It depends on what you mean by pause the activity:

• If you want to prevent the user from doing anything on the activity when there is no internet then you should show a no network view and hide everything else
• If you want to actually trigger the on pause on that activity I think that can only happen when you move to another activity
• You can also finish the activity and show a toast message that you can't work without an internet connection

Please provide more clarification I might be able to help

• UPDATE:

Based on your comment, you can show a view with a retry button and hide the ListView

You can also make use of ListView.setEmptyView(View), have a look at this StackOverflow post about that setEmptyView on ListView not showing its view in a android app

But I usually create something like that inside a RelativeLayout:

`

<LinearLayout
    android:id="@+id/layoutNoInternet"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical"
    android:visibility="gone">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textStyle="bold"
        android:text="Please check your internet connection!" />

    <Button
        android:id="@+id/btnRetry"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Retry"/>
</LinearLayout>

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

`

I set the visibility of no internet layout to gone or visible
