Send SMS in android

You can use this to send sms to any number.
Use this in XML

<Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New Button"
        android:onClick="sendsms"
        android:id="@+id/button2"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true" />

Use this in Activity Class

 public void sendsms(View view) {
        String phoneNumber = "+880xxxxxxxxxx";
        String message = "Welcome to sms";
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("sms:" + phoneNumber));
        intent.putExtra("sms_body", message);
        startActivity(intent);
    }

Need SEND_SMS permission.

<uses-permission android:name="android.permission.SEND_SMS" />

Android: Time Loop in milliseconds

You can use timer or thread handler

   timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run() {

               Do your own code
                ///////schedule the timer, after the first 100ms the TimerTask will run every 1000ms
            }
        }, 1000, 1000);

Can Use Another handler

  Handler handler = new Handler();
        handler.postDelayed(
            new Runnable() {
                public void run() {
                    afficher();
                }
            }, 1000L);

How to (turn off wifi (if on wifi )) and turn on mobile data connection in Android

Use this method to (turn off wifi(if on wifi)) and turn on mobile data connection

  public boolean isConnected() {
        ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
        boolean NisConnected = activeNetwork != null && activeNetwork.isConnected();
        if (NisConnected) {
            //  if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE || activeNetwork.getType() == ConnectivityManager.TYPE_WIFI)
            if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
                WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
                //  wifi.setWifiEnabled(true);//Turn on Wifi
                wifi.setWifiEnabled(false);//Turn off Wifi
            } else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE)
                return true;
            else
                return false;
        }
        return false;
    }

after use up method , if you can see internet not connection then use bellow method to turn on Mobile data

 private void setMobileDataEnabled(Context context, boolean enabled) {
        try {
            final ConnectivityManager conman = (ConnectivityManager)
                    context.getSystemService(Context.CONNECTIVITY_SERVICE);
            final Class conmanClass = Class.forName(conman.getClass().getName());
            final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
            iConnectivityManagerField.setAccessible(true);
            final Object iConnectivityManager = iConnectivityManagerField.get(conman);
            final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
            final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
            setMobileDataEnabledMethod.setAccessible(true);
            setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
    }

Also Need Permission in Manifests

 <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"></uses-permission>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>

Pass a String from one Activity to another Activity in Android

Post Value from Activity Class

 Intent ii = new Intent(this, GameStartPage.class);
                   // ii.putExtra("pkgName", B2MAppsPKGName);
                    ii.putExtra("pkgName", YourValue);
                    ii.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    startActivity(ii);

Get Value from Another Activity Class

  pkgn = getIntent().getExtras().getString("pkgName");

Find application running in foreground from service in Android

Use this code in Service to get foreground apps and take your own task.

 try {
            ActivityManager activityManager = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE);
            List<ActivityManager.RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();

            //   final String packageName = context.getPackageName();
            for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
                //   if (appProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND && appProcess.processName.equals()) {
                if (appProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
                    Log.i("Foreground App", appProcess.processName);
                    String B2MAppsPKGName = appProcess.processName;

                    ////////Select Package name From SQLite DataBase//////////

                    OurStoreAppsPackages = new ArrayList<String>();
                    OurStoreAppsPackages = databaseHelper.getOurAllAppsPackage();

                    if (OurStoreAppsPackages.contains(B2MAppsPKGName)) {
                        //  if (storedPackageName == true) {
                        Log.i("DatabaseForeground App", B2MAppsPKGName);

                        ////// Go to GameStartPage page ./////////
                        Intent ii = new Intent(this, GameStartPage.class);
                        ii.putExtra("pkgName", B2MAppsPKGName);
                        ii.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                        startActivity(ii);
                    }
                }
            }
        } catch (Exception e) {
