Hi,
For my app,It is very necessary to display the location of a vehicle at a particular location.The location of the vehicle is given by the json webservices.Also the vehicle is moving and location is updated by the webservice.But according to my code the vehicle is not moving.How can I implement the movement of vehicle in my app?How can I implement the location change using timer?Is there any other methods to implement this?
Please help me
Here is my code

Use Timer..
mytimer = new Timer();
final TimerTask mytask = new TimerTask() {
public void run() {
//your code here
}
});
mytimer.scheduleAtFixedRate(mytask, int delay, int time);

Class To Start Service
allVehiclesSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int position, long arg3) {
String item=allVehiclesSpinner.getItemAtPosition(position).toString();
if(!item.equalsIgnoreCase("Select")){
position=0;
vdetails.vehicleNo = item;
dbhHelper.opendatabase();
vdetails=dbhHelper.getVehicleId(item);
dbhHelper.close();
Intent intent = new Intent(A.this,
Service_A.class);
startService(intent);
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
USE SERVICE TO UPDATE WEBSERVICE AFTER 1 SEC
Service_ A extend service
{
private Handler handler = new Handler();
#Override
public void run() {
// TODO Auto-generated method stub
handler.postDelayed(Service_ A.this,1000);
}
//do you code
}

Try to use thread to invoke async task every second use below code to replace
getLiveTrackingsAsyncTask livetask=new getLiveTrackingsAsyncTask();
livetask.execute();
Thread thread = new Thread(new Runnable() {
#Override
public void run() {
try {
Thread.sleep(1 * 1000);
new getLiveTrackingsAsyncTask.execute();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
});
thread.start();

Use Multiple Android Activities

Anyone can help me to debug where I m going wrong. Test Code may get from:
https://drive.google.com/file/d/0Bz1lc03pNQm6Qkw3bE93dWxjdXc/view?usp=sharing
Scenario, I have 3 activities
Main, Splash and menu. First I call Splash activity for 5 seconds after 5 seconds I call menu activity its not working from menu I want to call Main activity. If I skip Menu activity than its working fine.
Splash Activity
public class Splash extends Activity{
MediaPlayer ourSong;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
ourSong = MediaPlayer.create(Splash.this, R.raw.dj);
ourSong.start();
Thread timer = new Thread()
{
public void run()
{
try
{
sleep(5000);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
finally
{
Intent start = new Intent("com.example.test.menu");
startActivity(start);
}
}
};
timer.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
ourSong.release();
finish();
}
}
Menu Activity
public class menu extends ListActivity{
String classes[] = {"MainActivity", "example1", "example1", "example1", "example1"};
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(menu.this, android.R.layout.simple_list_item_1, classes));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
String cheese = classes[position];
try
{
Class ourclass = Class.forName("com.example.test."+cheese);
Intent ourIntent = new Intent(menu.this, ourclass);
startActivity(ourIntent);
}
catch(ClassNotFoundException e)
{
e.printStackTrace();
}
}
}
Main Activity
public class MainActivity extends Activity {
int counter;
Button add, subtruct;
TextView textarea;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
counter = 0 ;
add = (Button)findViewById(R.id.button1);
subtruct = (Button)findViewById(R.id.button2);
textarea = (TextView)findViewById(R.id.textView1);
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
counter++;
textarea.setText("Your total is"+counter);
}
});
subtruct.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
counter--;
textarea.setText("Your total is"+counter);
}
});
}
}

Your code:
Thread timer = new Thread()
{
public void run()
{
try
{
sleep(5000);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
finally
{
Intent start = new Intent("com.example.test.menu");
startActivity(start);
}
}
};
timer.start();
Right code:
Thread timer = new Thread()
{
public void run()
{
try
{
sleep(5000);
}
catch (InterruptedException e)
{
e.printStackTrace();
}
finally
{
Intent start = new Intent(Splash.this, menu.class);
startActivity(start);
}
}
};
timer.start();
Tip: Don't use lowerCase for Class Names

Android: Not able to store location in SharedPreference

Here, I'm using the current location of the user as well as the a location which is stored previously and showing path between them.
I'm able to get the correct current location but the location I'm trying to store permanently in Shared Preferences are just getting stored until application is running. Once the application is removed and opened again the saved location gets initialised back to 0.0.
I want to store latitude and longitude permanently once after user press save/change location button.

Please let me know the correct changes in the code to get store the location permanently...

You can saved value in preference on onPause() or any Button click event where you want using below code.
edit.putFloat("latestlati", Float.valueOf((float) loc.getLatitude()))
edit.putFloat("latestlongi", Float.valueOf((float) loc.getLatitude()));
edit.putBoolean("locsaved", true);
edit.commit();
You can get saved value from preference on onResume() using below code.
savelati = pref.getFloat("latestlati", 0.0);
savelongi= pref.getFloat("latestlongi", 0.0);
islocsaved=edit.getBoolean("locsaved", true);
and for more information go to Android Shared preferences example or http://www.vogella.com/tutorials/AndroidFileBasedPersistence/article.html

You need to save the value of longitide and latitude first in the shareprefrences.
edit.putFloat("latestlati", Float.valueOf((float) loc.getLatitude());
edit.putFloat("latestlongi", Float.valueOf((float) loc.getLongitude);

For the better suggestion you have to take your SharedPreferance instance globally
then in your onLocationChanged(Location location) change method you can do this code
edit.putFloat("latestlati", Float.valueOf((float) loc.getLatitude()))
edit.putFloat("latestlongi", Float.valueOf((float) loc.getLatitude()));
edit.putBoolean("locsaved", false);
edit.commit();
So, that every location change your value for the location is updated and after come to your activity you always get the refresh/latest value.
with onCreate() or onResume() you can get the
savelati = pref.getFloat("latestlati", 0.0);
savelongi= pref.getFloat("latestlongi", 0.0);
islocsaved=edit.getBoolean("locsaved", false);

Running SoundPool on Background with AsyncTask

I am trying to play 5 SoundPool one after the other on Background using AsyncTask for it. But I wanna click an ImageView while sounds are running. The problem begins when SoundPool uses getBaseContext() that blocks my ImageView while doInBackground is running.

Call updatePosition() method after mediplayer starts..It works for me.
private final Handler handler = new Handler();
private final Runnable updatePositionRunnable = new Runnable() {
public void run() {
updatePosition();
}
};
private void updatePosition() {
handler.removeCallbacks(updatePositionRunnable);
if (player != null) seekbar.setProgress(player.getCurrentPosition());
handler.postDelaye(updatePositionRunnable, 500);
}
#Override
public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {
// TODO Auto-generated method stub
player.seekTo(arg1);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}

SurfaceView mPreview=(SurfaceView)findViewById(R.id.surface);
mPreview.postDelayed(runnable,200);
Runnable runnable = new Runnable() {
#Override
public void run() {
if (mMediaPlayer != null) {
if (isPlaying) {
// converting current position into seconds so dividing by
// 1000
try {
currentPosition = mMediaPlayer.getCurrentPosition();
mVideoProgress
.setProgress((int) ((currentPosition / (float) mMediaPlayer
.getDuration()) * 100f));
} catch (Exception e) {
e.printStackTrace();
}
mPreview.postDelayed(runnable, 150);
}
}
}
};
