Question

I have received some code from another team and started to simple improvement and re-factoring.
The first phase is adding unit test to the project. I need to test functionality of parsing input sms.
Related to above information my question is:
– Can I send sms to the emulator port from test method?
I have writen next code but have no received anything …

@Test
public void sendSmsTest() {
    SmsManager smsManager = SmsManager.getDefault();
    smsManager.sendTextMessage("5554", null, getSms("sms1"), null, null);
}

private String getSms(String smsKey) {
    return (String) smsMessages.get(smsKey);
}

Thanks.

After restarting emulators and IDE I have received next error in console:

Test running failed: Exception thrown
in onCreate() of
ComponentInfo{com.example/android.test.InstrumentationTestRunner}:
java.lang.NullPointerException

Answer 1

I started 2 emulator instances and was able to send an SMS from instance to the other, but… I had a problem where it would only send from the second instance I started. Look at this post:
