Am presently trying to call an AsyncTask from my service, but every time the service is called the AsyncTask that it is meant to perform is not called or not working. i have tried using this same service to call a text message method and it works but it is not working for the AsyncTask. My service class is below.
public class TimerLocationService extends Service {
private static boolean isRunning = false;
#Override

return null;

super.onDestroy();
stopSelf();
isRunning = false;
// Toast.makeText(this, "Timer onDestroy()", Toast.LENGTH_LONG).show();

i'm observing a weird scenario here. I have a background android service which is running perfectly. but when I kill the process or application from my RecentApps my Application calls the onStartCommand method again. I don't know where I went wrong. I have searched alot but didn't find any appropriate solution. Could someone please mention what I did wrong? Thanks in Advance

here in the logcat the last line shows that its call the onstartcommand method again. Why is it so? Even my Activity is not running I meant to say (the service starts in oncreate method on on acticity, but here in the logcat the control goes directly to the onStartCommand when i destroy my App ).
Your service will be START_STICKY so the android framework is restarting it -> This will give you call to onStartCommand()
I changed my service to START_NOT_STICKY so the android framework will not restart my service on its own without any explicit request from out application
To make your service of START_NOT_STICKY, just return value Service.START_NOT_STICKY from onStartCommand()
This worked and solved my issue

I am running app using Emulator.Is it possible to run this problem in emulator,because writing to external directory
Can anyone help me?
Use
public DownloadService() {
super("DownloadService");
// TODO Auto-generated constructor stub
}
Instead of
public DownloadService(String name) {
super("DownloadService");
// TODO Auto-generated constructor stub
}
UPDATE:
You have to declare a default constructor which calls the public IntentService (String name) super constructor of the IntentService class you extend. ie. In simple words, you need to provide no-argument constuctor for your service ,without which android wont be able to instantiate your service.
you start the intentservice using startService(your_intent); And as per the documentation
You should not override onStartCommand() method for your
IntentService. Instead, override onHandleIntent(Intent), which the
system calls when the IntentService receives a start request.

return JUMLAH_GANGGUAN;
}
}
How do I call method getambil_jmlgangguan() in another activity e.g MainActivity and get result of JUMLAH_GANGGUAN periodically.
For this,first i am getting the top activity from the stack and then matching the string of Facebook in logcat..
I am using this Code,
public class MyService extends Service
{
public static String Tag = "Task";
public static String Tag1 = "Top Running Task";
ActivityManager am ;
String packageName ;
Handler handler;
int count=0;
#Override
public int onStartCommand(Intent intent,int flags, int startId)
{
// TODO Auto-generated method stub
super.onStartCommand(intent, flags,startId);
Toast.makeText(this, "Service running", Toast.LENGTH_SHORT).show();
handler = new Handler(){
#Override
public void handleMessage(Message msg)
{
// TODO Auto-generated method stub
super.handleMessage(msg);
// Browser.clearHistory(getContentResolver());
//Browser.clearSearches(getContentResolver());
String packageName = am.getRunningTasks(1).get(0).topActivity.getPackageName();
if((packageName).indexOf("browser")!= -1)
{
// Toast tost=Toast.makeText(getApplicationContext(), packageName.toString(), 1);
//tost.show();
try {
Process process = Runtime.getRuntime().exec("logcat -d");
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(process.getInputStream()));
StringBuilder log = new StringBuilder();
String line = "";
while ((line = bufferedReader.readLine()) != null)
{
if(line.contains("facebook.com"))
{
//Browser.addSearchUrl(getContentResolver(), "google");
Log.i(Tag1,"ww"+ line);
/*Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);*/
//android.os.Process.killProcess(pid);
}
//log.;
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
//}
}
};
new Thread(new Runnable()
{
public void run()
{
while(true)
{
try
{
Thread.sleep(1000);
handler.sendEmptyMessage(0);
}
catch (InterruptedException e) {}
}
}
}).start();
return START_NOT_STICKY;
}
#Override
public void onDestroy()
{
super.onDestroy();
am.killBackgroundProcesses(packageName);
Log.i(Tag,"destory ");
}
#Override
public IBinder onBind(Intent intent)
{
//TODO for communication return IBinder implementation
return null;
}
}
I am deleting the History and cache too.
After that,i am able to block facebook but first time,it works fine but second time it does not work,it keeps its history for 5-6 seconds and after that again worked fine.
