Remove the Drawable object from FolderModel and from AppModel and save it as an id or image url.
The Drawables are not serializable clases and it's expensive to keep them in memory.
Try something like this:
JSONArray list;
list = new JSONArray(jsonString);
foldersList = new ArrayList<FolderModel>();
FolderModel f;
for (int i = 1; i < list.length(); ++i) {
f=new FolderModel();
JSONObject obj = list.getJSONObject(i);
f.setName(obj.getString("name").toString());
}
I usually use another way to parse:
FolderModel[] arrayModels = gson.fromJson(jsonString, FolderModel[].class);

I would like to add texture to my model but I keep getting this error . Any help would be appreciated. Thanks
for (String i : faces) {
for (String j : i.split(" ")) {
iCoords[faceIndex] = (short) faceIndex++;
String[] faceComponent = j.split("/");
String vertex = vertexes.get(Integer.parseInt(faceComponent[0]) - 1);
// this line throws NFE
String texture = textures.get(Integer.parseInt(faceComponent[1]) - 1);
String vertexComp[] = vertex.split(" ");
String textureComp[] = texture.split(" ");
for (String v : vertexComp) {
vCoords[vertexIndex++] = Float.parseFloat(v);
}
for (String t : textureComp) {
tCoords[textureIndex++] = Float.parseFloat(t);

Your problem is in
String imgSrc = divimg.attr("src");
because divimg== null. The stacktrace is clearly showing this. Further the app crashes. Why didn't you tell? Why didn't you post more of the logcat/stacktrace? You would have been helped sooner.
Change your code to:
Element divimg = imgsdiv.getElementsByClass("lazy img-responsive").first();
if ( divimg==null)
{
Log.e(TAG, "divimg==null: " + titolo);
immaginiart.add(null);
}
else
{
String imgSrc = divimg.attr("src");
InputStream input = new java.net.URL(imgSrc).openStream();
bitmap = BitmapFactory.decodeStream(input);
immaginiart.add(bitmap);
}
This will not decode the image but just display an empty image.
I am developing an android application in which I am displaying conversation List.
My code works fine in Samsung Galaxy S,Nexus one and Galaxy Nexus but the query is giving a problem in my Galaxy Grand phone.
Here is my code:
public ArrayList<String> getSMS()
{
ArrayList<String> sms = new ArrayList<String>();
Uri uriSMSURI = Uri.parse("content://mms-sms/conversations/");
Cursor cursor = getContentResolver().query(uriSMSURI, null, null, null, "date desc");
//cursor.moveToFirst();
while (cursor.moveToNext())
{
String address = cursor.getString(cursor.getColumnIndex("address"));
String body = cursor.getString(cursor.getColumnIndexOrThrow("body"));
String read = cursor.getString(cursor.getColumnIndexOrThrow("read"));
//to fetch the contact name of the conversation
String contactName = address;
Uri Nameuri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(address));
Cursor cs= getContentResolver().query(Nameuri, new String[]{PhoneLookup.DISPLAY_NAME},PhoneLookup.NUMBER+"='"+address+"'",null,null);
if(cs.getCount()>0)
{
cs.moveToFirst();
contactName = cs.getString(cs.getColumnIndex(PhoneLookup.DISPLAY_NAME));
}
sms.add(contactName + "\n"+body);
}
return sms;
}
The following is the stackTrace:

I tried to use Text-to-Speech but getting an nullpointerexception.I have many textviews with text init.what i tried to do is that when user clicks on this textviews than text-to-speech speaks up the text which is on that particular textview.Following is the code of 2 of my classes which handles text-to-speech.I have also marked down the lines where i'm getting the nullpointerexception.Please tell me what am i doing wrong?! Thank you.
My TextSpeaker class:
public class TextSpeaker implements OnInitListener{
TextToSpeech tts;
public TextSpeaker(Context c,OnInitListener listener){
tts = new TextToSpeech(c,listener); //Getting NullPointerException here
}
#Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR){
tts.setLanguage(Locale.US);
}
}
}
My TextViewClick class:
public class TextViewClick implements OnClickListener{
public String textHolder;
Context c;
TextToSpeech.OnInitListener listener;
TextSpeaker tts1 = new TextSpeaker(c,listener); //Getting NullPointerException here
#Override
public void onClick(View v) {
TextView tv=(TextView) v;
tv.setTextColor(R.color.red);
textHolder = (String) tv.getText();
System.out.println(textHolder);
tts1.tts.speak(textHolder, TextToSpeech.QUEUE_FLUSH, null);
}
}

It appears that your Context is never initialized. Make sure that you initialize the context before you call the constructor for TextSpeaker.
You also don't need to pass an onInitListener, your TextSpeaker is already an OnInitListener. You can try this in your TextViewClick:
public class TextViewClick implements OnClickListener
{
public String textHolder;
public TextViewClick(Context c)
{
TextSpeaker tts1 = new TextSpeaker(c);
}
#Override
public void onClick(View v)
{
TextView tv=(TextView) v;
tv.setTextColor(R.color.red);
textHolder = (String) tv.getText();
System.out.println(textHolder);
tts1.tts.speak(textHolder, TextToSpeech.QUEUE_FLUSH, null);
}
}
And your TextSpeaker would change as well:
public class TextSpeaker implements OnInitListener
{
TextToSpeech tts;
public TextSpeaker(Context c)
{
tts = new TextToSpeech(c, this);
}
#Override
public void onInit(int status) {
if(status != TextToSpeech.ERROR){
tts.setLanguage(Locale.US);
}
}
}
In addition, make sure you have enabled TTS in your device settings.
