27,595 PointsFrames Skipped! (app may be doing too much work)
Hey Guys,
So this one has been giving me some difficulty... I did the TreeHouse Blog Reader Tutorial (all the code worked for their blog), tried to redo it with my wordpress blog (TechWarriorz) and it came up with the following error:
Exception caught: java.lang.NegativeArraySizeException: -1
Then it said: I/Choreographer﹕ Skipped 1405 frames! The application may be doing too much work on its main thread.
Here is a copy of my code:
public class MainListActivity extends ListActivity {
protected String[] mBlogPostTitles;
public static final int NUMBER_OF_POSTS = 20;
public static final String TAG = MainListActivity.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_list);
if (isNetworkAvailable()) {
GetBlogPostsTask getBlogPostsTask = new GetBlogPostsTask();
getBlogPostsTask.execute();
}
else {
Toast.makeText(this, "Network is unavailable!", Toast.LENGTH_LONG).show();
}
//Toast.makeText(this, getString(R.string.no_items), Toast.LENGTH_LONG).show();
}
private boolean isNetworkAvailable() {
ConnectivityManager manager = (ConnectivityManager)
getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = manager.getActiveNetworkInfo();
boolean isAvailable = false;
if (networkInfo != null && networkInfo.isConnected()) {
isAvailable = true;
}
return isAvailable;
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main_list, menu);
return true;
}
private class GetBlogPostsTask extends AsyncTask<Object, Void, String> {
@Override
protected String doInBackground(Object... arg0) {
int responseCode = -1;
try {
URL blogFeedUrl = new URL("http://techwarriorz.com/v2/?json=1");
HttpURLConnection connection = (HttpURLConnection) blogFeedUrl.openConnection();
connection.connect();
responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
InputStream inputStream = connection.getInputStream();
Reader reader = new InputStreamReader(inputStream);
int contentLength = connection.getContentLength();
char[] charArray = new char[contentLength];
reader.read(charArray);
String responseData = new String(charArray);
JSONObject jsonResponse = new JSONObject(responseData);
String status = jsonResponse.getString("status");
Log.v(TAG, status);
JSONArray jsonPosts = jsonResponse.getJSONArray("posts");
for (int i = 0; i < jsonPosts.length(); i++) {
JSONObject jsonPost = jsonPosts.getJSONObject(i);
String title = jsonPost.getString("title");
Log.v(TAG, "Post " + i + ": " + title);
}
}
else {
Log.i(TAG, "Unsuccessful HTTP Response Code: " + responseCode);
}
}
catch (MalformedURLException e) {
Log.e(TAG, "Exception caught: ", e);
}
catch (IOException e) {
Log.e(TAG, "Exception caught: ", e);
}
catch (Exception e) {
Log.e(TAG, "Exception caught: ", e);
}
return "Code: " + responseCode;
}
}
}
You guys can see a copy of my JSON data over at http://techwarriorz.com/v2/?json=20

4,266 PointsI came up with the same error and got an answer that helped:
I'm hoping Ben Jakuben can weigh in a bit more on this showing up on this particular project.
