android - 当应用程序被杀死时，互联网广播接收器不工作

Question

我用广播接收器监听改变了的互联网连接。在前台，一切都很棒。但是当应用程序被杀死时它不起作用。

list :

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />

我的广播接收器( NetworkReceiver ):

application.registerReceiver(new BroadcastReceiver() {
                @Override
                public void onReceive(Context context, Intent intent{
            }, new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));

网络约束:

public class NetworkConstraint implements Constraint {

    @Override
    public boolean isConnected() {
        ConnectivityManager connectivityManager = (ConnectivityManager) application.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();

        return activeNetworkInfo != null && activeNetworkInfo.isConnected();
    }


    @Override
    public void applyToJobInfo(@NonNull JobInfo.Builder jobInfoBuilder) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        jobInfoBuilder.setRequiredNetworkType(JobInfo.NETWORK_TYPE_ANY);
        }
    }

}

细胞约束:

public class CellServiceConstraint implements Constraint {

    @Override
    public boolean isConnected() {
        return new TelephonyServiceState().isConnected(application);
    }

    @Override
    public void applyToJobInfo(@NonNull JobInfo.Builder jobInfoBuilder) {
    }
}

请引用此链接 https://developer.android.com/training/monitoring-device-state/connectivity-monitoring.html . O 不支持 connectivity_change 操作。你可以尝试另一种方式。
