I am trying to implement a login after is shown progressbar but it shows an erro.Below is the code I am using
class PostService extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... params) {
String s = UserFunctions.response;
Log.d(Details.TAG, "checking i response...");
UserFunctions.basicLogin(email, password);
Log.d(Details.TAG,
s + " " + UserFunctions.basicLogin(email, password));
return s;
}
Intent i;
#Override
protected void onPostExecute(String r) {
// TODO Auto-generated method stub
super.onPostExecute(UserFunctions.response);
Log.d(Details.TAG, "Password Point");
if(UserFunctions.basicLogin(email, password)){
i = new Intent("com.example.eve_haps.DASHBOARDACTIVITY");
startActivity(i);
}else {
Toast.makeText(MainActivity.this,
"Login UnSuccesful. Check email and/or password",
Toast.LENGTH_SHORT).show();
}
}
}
But it returns an error log

Try this, hope it helps you,

lname.setText(obj.getString("Lname").toString());
I'm trying to get a looper thread to work but despite all attempts, it crashes. I'm not using the HandlerThread class, as I'm doing quite a bit of 802.11 related stuff in the thread itself and posting Runnables with lots of duplicate code doesn't seem to be the right way to go here.
Here the skeleton of the looper thread class:
public class WiFiScanner extends Thread {
Looper mLooper;
Handler mHandler;
#Override
public void run() {
Looper.prepare();
synchronized(this) {
mLooper = Looper.myLooper();
notifyAll();
}
mHandler = new Handler() {
#Override
public void handleMessage(Message msg) {
..... // message parsing
}
}
}
/* waits for Looper initialization */
public boolean waitForLooper() {
synchronized(this) {
while(mLooper == null) {
try {
wait();
} catch (InterruptedException e) {}
}
}
return true;
}
}
and the code initializing it in the main activity:
wifiScanner = new WiFiScanner(
... // callback stuff
);
wifiScanner.start();
wifiScanner.waitForLooper();
wifiScanner.initialize();
initialize is a simple function in the WiFiScanner class, posting a message bundle to the message queue:
public void initialize() {
Message msg = mHandler.obtainMessage();
Bundle b = new Bundle();
WiFiMsg msgId = WiFiMsg.INITIALIZE;
b.putSerializable("msgId", msgId);
msg.obj = b;
mHandler.sendMessage(msg);
}
Despite waitForLooper() returning successfully, the call to initialize() causes a null pointer exception. I assume the looper isn't really in a state to have message dispatched into the queue as a static delay of 500ms between waitForLooper() and initialize() circumvents this issue.
Any ideas on how to fix this in a reasonably elegant way?

Your notify should be after mHandler is set, not mLooper - since your NPE is on mHandler.
I am making a music player application for my Computing project. I got it working but found that using objects would get more more marks. As a result, I changed some of my code to incorporate the use of objects, but it doesn't work when I execute my application. Btw I am quite new to Java so it's possible I made a silly mistake.
When I used this code the function I tried to implement worked:
private void SongTitleEndTime(){
try {
TextViewSongTitle = (TextView)findViewById(R.id.songTitle);
if (id != 0 ){
String where = MediaStore.Audio.Media._ID + " = " + "'" + id + "'";
final Cursor mCursor = managedQuery(
MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
new String[] {MediaStore.Audio.Media.TITLE, MediaStore.Audio.Media.ARTIST, MediaStore.Audio.Media._ID.toString(), MediaStore.Audio.Media.ALBUM_ID.toString()}, where , null,
null);
mCursor.moveToFirst();
String title = mCursor.getString(0);
String artist = mCursor.getString(1);
String name = title + " - " + artist;
TextViewSongTitle.setText(name);
String fulltime;
albumfullid = Long.parseLong(mCursor.getString(3));
TextView EndTime = (TextView) findViewById(R.id.endtime);
long Minutes = TimeUnit.MILLISECONDS.toMinutes(mMediaPlayer.getDuration());
long Seconds = TimeUnit.MILLISECONDS.toSeconds(mMediaPlayer.getDuration()) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(mMediaPlayer.getDuration()));
if (Seconds < 10) {
String second = "0" + String.valueOf(Seconds);
fulltime = Minutes + ":" + second;
} else {
//else display as normal
fulltime = Minutes + ":" + Seconds;
}
EndTime.setText(fulltime);
//display the duration of song
}
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} //catch for errors
}
But when I tried this, I got an error:
Main Class:
private void SongTitleEndTime() {
try {
final TextView TextViewSongTitle = (TextView) findViewById(R.id.songTitle);
if (CurrentSongID != 0) {

Song is an Activity. Thus you can't call manageQuery before onCreate has been called. That's your error.
I'm developing an app for Android to download the pic from all the friends. I successfully made my app logging in. Now, I need to parse a JSON and download some of the pics. Here the sources:

for (int y = 0; y < validContacts.toArray().length; y++){
if (jFriend.getString("name").equals((String)(validContacts.get(y)))){
String id = jFriend.getString("id");
Log.d("SYNCRO", "Adding pic for id \"" + id + "\"");
idToDowload.add(id);
}
}
}
FacebookPicDownloader downloader = new FacebookPicDownloader(context);
downloader.execute((String[]) idToDownload.toArray());
} catch (JSONException e) {
Log.d("SYNCRO", e.getMessage());
}
return null;
}
#Override
protected void onPostExecute(Integer result){
dialog.dismiss();
}
}
The problem is that it downloads just the first pic, and then the app crashes...here the logcat:

Thanks to anyone will help me.
The crash is caused by this code: (String[]) idToDownload.toArray().
Try creating a new String array instead of using the cast:
Replace the line
downloader.execute((String[]) idToDownload.toArray());
By:
String[] stringArray= new String[idToDownload.size()];
idToDownload.toArray(stringArray);
downloader.execute(stringArray);
