    Hi there,

    I have issues with android services and broadcast activity when doing some development.

    I am using Android 8.0 as a test device btw.

    Code (Text):
    1.    
    2. serviceIntent.setComponent(new ComponentName("com.service.sillyservice", "com.service.sillyservice.SillyService"));
    3. serviceIntent.putExtra("COMMAND","ls");
    4. startService(serviceIntent);
    5.  
    Assuming it will invoke the start service from another activity:
    public int onStartCommand(Intent var1, int var2, int var3) {

    its return value is "1", how do I get the value of "1" and store it some where.


    Code (Text):
    1.         broadcastIntent.setComponent(new ComponentName("com.broadcast.vulnerablereceiver", "com.elearnsecurity.vulnerablereceiver.VulnerableReceiver"));
    2.                     broadcastIntent.setAction("com.broadcast.vulnerablereceiver.CHANGEPW");
    3.                     broadcastIntent.putExtra("PASSWORD",1);
    I am trying to mirror the same here:
    run app.broadcast.send --action com.broadcast.vulnerablereceiver.CHANGEPW" --component com.broadcast.vulnerablereceiver com.broadcast.vulnerablereceiver.VulnerableReceiver --extra string PASSWORD 1

    However, for some it show something like:
    Unable to start receiver com.broadcast.vulnerablereceiver.VulnerableReceiver: java.lang.NullPointerException: println needs a message
