seems to work fine I have set up a Broadcast Receiver to capture SMS messages. The Class display the message using Toast but I need to write the String to a file but because it's not an Activity it doesn't work. , Try passing context into SaveMessage...
code :
SaveMessage(context, str);
public void SaveMessage(Context context, String message) {

    FileOutputStream FoutS = null;
    OutputStreamWriter outSW = null;

    try {
        FoutS = context.openFileOutput("Message.dat", Context.MODE_PRIVATE);

        // Rest of try block here
    }
    // 'catch' and 'finally' here
}

like below fixes the issue Move your BroadcastReceiver to a separate class. In your manifest you have declared "com.example.broadcastreceiver.MainActivity" to be both an Activity and a BroadcastReceiver, but it isn't. It is only an Activity. And it can't be both.
