यह त्रुटि क्यों हुई? java.lang.RuntimeException:

Question

का उपयोग करने से पहले छवि लोडर को कॉन्फ़िगरेशन के साथ अवगत होना चाहिए। मैंने गिटहब (from Here) से एक छवि डाउनलोडर कोड डाउनलोड किया है अब जब मैं अपने webservice से छवि डाउनलोड करने का प्रयास कर रहा हूं तो मुझे यह रनटाइम अपवाद मिल रहा है "ImageLoader होना चाहिए उपयोग करने से पहले विन्यास के साथ init "।

मैं इसे समझने में सक्षम नहीं हूं।

और ये मेरे अनुकूलक:

Answer 1

मैं अपने निर्माता में इस लाइन को शामिल किया है और इसकी मेरे लिए काम किया ...

imageLoader.init(ImageLoaderConfiguration.createDefault(context)); 

Answer 2

protected ImageLoader imageLoader; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.activity_main); 

imageLoader = ImageLoader.getInstance(); 
imageLoader.init(ImageLoaderConfiguration.createDefault(this));
