그리고 json소스를 빼면 잘돌아갑니다..

해당 소스입니다.

String url = "file:///android_asset/www/index.html";  
        
        Intent intent = getIntent();
		Bundle extra = intent.getExtras();
		String jsonData = extra.getString("com.parse.Data");
			
        try {		
			JSONObject json = new JSONObject(jsonData);
			url = json.getString("url");
		} catch (JSONException e) {
			e.printStackTrace();
		}

 

간략 설명드리고 전체소스첨부할꼐요..

폰갭으로 패킹하고 있구욧.

푸시는 PARSE.COM의 것을 사용하고 있습니다.

푸시에 담긴 데이타 추출할수있다고 하여 짠 부분입니다.

 

앱이 그냥 죽어버려 테스트를 할수가 없네요 ㅠㅠ

 

고수님들 도와주세요 ㅠㅠ

 

MainActivity.java

import android.content.Intent;
import android.os.Bundle;
import android.view.Gravity;
import com.parse.*;
import org.apache.cordova.*;
import org.json.JSONException;
import org.json.JSONObject;

public class MainActivity extends DroidGap {
	
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		
		//parse.com을 이용한 푸시알림
        Parse.initialize(this, "xxxxxxxx", "xxxxxxxx"); 
        PushService.setDefaultPushCallback(this, MainActivity.class); 
        ParseInstallation.getCurrentInstallation().saveInBackground();
        ParseAnalytics.trackAppOpened(getIntent());
        PushService.subscribe(this, "", MainActivity.class);  
        
        String url = "file:///android_asset/www/index.html";  
        
        Intent intent = getIntent();
		Bundle extra = intent.getExtras();
		String jsonData = extra.getString("com.parse.Data");
			
        try {		
			JSONObject json = new JSONObject(jsonData);
			url = json.getString("url");
		} catch (JSONException e) {
			e.printStackTrace();
		}
       
		super.loadUrl(url);
		
			    
	       
	}

자체 해결했습니다.

 

jsonObject json 이녀석이 null이라

 
 Intent intent = getIntent();
        try {
        Bundle extra = intent.getExtras();        
        String data = extra.getString("com.parse.Data");
        if(data !=null){
        JSONObject json = new JSONObject(data);
        url = json.getString("url");
        }        
        } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        }
 
 
jsonObject는 null값이면 안된다는걸 배웠네요 ㅎㅎ;

super.loadUrl(url); 이건 뭐죠? 이거 빼고 해보세요

Gradler (109,780 포인트) 님이 2013년 12월 27일 답변
그건 phonegap에서 url불러오는거예요..

Intent intent = getIntent();
        Bundle extra = intent.getExtras();
        String jsonData = extra.getString("com.parse.Data");
             
        try {       
            JSONObject json = new JSONObject(jsonData);
            url = json.getString("url");
        } catch (JSONException e) {
            e.printStackTrace();
        }

이거만 추가하면 죽어요 정확하겐

  try {       
            JSONObject json = new JSONObject(jsonData);
            url = json.getString("url");
        } catch (JSONException e) {
            e.printStackTrace();
        }

이 try {} catch {}를 넣으면 앱이 죽습니다 ㅠㅠ

super.loadUrl(url); 을 String url = "file:///android_asset/www/index.html"; 바로 밑에다가 옮겨보심이..
에러로그를 보면 저기에서 널포인트로 죽고 있습니다.

try에서 걸린거였습니다.

jsonObject json 이녀석이 null이라

 Intent intent = getIntent();
        try {
        Bundle extra = intent.getExtras();        
        String data = extra.getString("com.parse.Data");
        if(data !=null){
        JSONObject json = new JSONObject(data);
        url = json.getString("url");
        }        
        } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        }
