Android Build a Weather App (2015) Hooking Up the Model to the View Setting the Weather Icon

Do Butterknife bindings fail? My code compiles, runs then fails on first line in updateDisplay().

I have tested the code, and attempted to isolate the error. Logcat details indicate that the error is occurring on the first executable line of the updateDisplay() method. If I put in a log.d call to write the temperature value to the log - it does. If I comment out the mTemperatureLabel.setText() line, then the failure moves to the next line. Logging values from getCurrentDetails() and directly from mCurrentWeather indicate that the JSON data is being received correctly. I just can't get it to display correctly. I suspect that the culprit is the Butterknife bindings (yes I am using @Bind).

Hey Michael! Could you post the problematic code? And maybe the error message you get as well?

Hey Michael! Check out the previous video at about the 1:25 mark :)

Thanks Ben. Somehow that part had been overlooked.

Hey Ben,

code as follows

    public static final String TAG = MainActivity.class.getSimpleName();

    private CurrentWeather mCurrentWeather;

    @Bind(R.id.temperatureLabel) TextView mTemperatureLabel;
    @Bind(R.id.humidityValue) TextView mHumidityValue;
    @Bind(R.id.precipValue) TextView mPrecipValue;
    @Bind(R.id.summaryLabel) TextView mSummaryLabel;
    @Bind(R.id.iconImageView) ImageView mIconImageView;

Hmm not sure. We should be able to see a more descriptive error message though. If you change the Log Level to 'Error' and change the box at the top right of Logcat to 'No Filters', are you able to see more about the error?

Logcat with No filters and Error level gives:

''' 11-12 07:33:29.690 902-933/com.mikelane9143.stormy E/AndroidRuntime: at com.mikelane9143.stormy.MainActivity.updateDisplay(MainActivity.java:96) 11-12 07:33:29.690 902-933/com.mikelane9143.stormy E/AndroidRuntime: at com.mikelane9143.stormy.MainActivity.access$200(MainActivity.java:29) 11-12 07:33:29.690 902-933/com.mikelane9143.stormy E/AndroidRuntime: at com.mikelane9143.stormy.MainActivity$1.onResponse(MainActivity.java:75) 11-12 07:33:37.800 359-388/system_process E/InputDispatcher: channel 'b3100858 com.mikelane9143.stormy/com.mikelane9143.stormy.MainActivity (server)' ~ Channel is unrecoverably broken and will be disposed!

Also worth noting - the code did work until adding in the Icon feature
