Question

Just out of curiosity. How can I create a new class from Class where the constructor does not require parameters? Here’s an example:

public static BroadcastReceiver startBroadcastReceiver(Context context, Class<?> receiverClass, String receiverTag) {
    BroadcastReceiver receiver = null;

    IntentFilter intentFilter = new IntentFilter(receiverTag);

    receiver = new receiverClass(); // <---- What's the correct syntax?

    if (receiver != null && intentFilter != null) {
        context.registerReceiver(receiver, intentFilter);
    }

    return receiver;
}

Here’s how I would call it:

MyTools.startBroadcastReceiver(context, MyBroadcastReceiver, MyBroadcastReceiver.TAG);

Thanks in advance.

Use this:

try{
    receiver = (BroadcastReceiver) receiverClass.newInstance();
}catch(Exception e){
    //do stuff
}

And you will call it

MyTools.startBroadcastReceiver(context, MyBroadcastReceiver.class, MyBroadcastReceiver.TAG);
