простой синтаксический анализ json с использованием папки с ресурсами (локальный)

Question

Json разбор с использованием папки с данными, но при запуске приложения xml макет не отображает проанализированные данные. Но это простой дизайн без json-анализа. Как это решить? , пожалуйста, дайте мне предложение. Ниже приведена информация о моем logcat. информация папки

public class MainActivity extends Activity { 
static String TAG = "MainActivity"; 
TextView text1,text2,text3,text4,text5,text6; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    text1=(TextView)findViewById(R.id.text2); 
    text2=(TextView)findViewById(R.id.text3); 
    text3=(TextView)findViewById(R.id.text4); 
    text4=(TextView)findViewById(R.id.text5); 
    text5=(TextView)findViewById(R.id.text6); 
    try{ 
    JSONObject obj= new JSONObject(loadJSONFromAsset()); 
    Log.e(TAG, "text1 :: " + obj.optString("dpfid")); 
    Log.e(TAG, "text2 :: " + obj.optString("version")); 
    Log.e(TAG, "text3 :: " + obj.optString("lastupdateon")); 
    Log.e(TAG, "text4 :: " + obj.optString("lastsyncdate")); 
    Log.e(TAG, "text5 :: " + obj.optString("emailid")); 
    text1.setText(obj.optString("dpfid")); 
    text2.setText(obj.optString("version")); 
    text3.setText(obj.optString("lastupdatedon")); 
    text4.setText(obj.optString("lastsyncdate")); 
    text5.setText(obj.optString("emailid")); 
}catch(Throwable e){ 
    Log.e(TAG,"Error e",e); 
    e.printStackTrace(); 
    } 
} 
public String loadJSONFromAsset(){ 
    String json=null; 
    try{ 
     InputStream is=MainActivity.this.getAssets().open("config.json"); 
     int size = is.available(); 
     byte[]buffer=new byte[size]; 
     is.read(buffer); 
     is.close(); 
     json =new String(buffer,"UTF-8"); 
    }catch(IOException e){ 
     Log.e(TAG,":e",e); 
    return null; 
    } 
    return json; 
}

Answer 1

Файл config.json есть проблема.

на "lastupdatedon": "2016-02-14 14:20" отсутствует ""

{ 
"dpfid": "sample-124-id", 
"emailid": "abc@gmail.com", 
"cmfoldername": "abc_at_gmail.com", 
"version": "4.4", 
"bulid": "abc", 
"configscreeninterval": 2, 
"pullrequestinterval": 60, 
"width": 400, 
"height": 300, 
"storagefree": 1024, 
"lastupdatedon": "2016-02-14 14:20" 
"lastsyncdate": "2016-02-14 14:20" 
}
