    android:layout_width="match_parent"

    android:layout_height="wrap_content">




    <com.google.android.gms.ads.AdView 

        xmlns:ads="http://schemas.android.com/apk/res-auto"

        android:id="@+id/adbhome"

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:layout_alignParentBottom="true"

        ads:adSize="BANNER"

        ads:adUnitId="@string/ads_banner">

    </com.google.android.gms.ads.AdView>




    <android.support.v7.widget.RecyclerView

        android:id="@+id/mrecycle"

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        android:layout_above="@+id/adbhome"

        android:layout_alignParentTop="true" />

How to get Device(Mobile) IME Number in Android Pro-grammatically

Need to add require permission in Android Manifest.xml file

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

Now need to Allow user permission at run time in your AppCompatActivity

public void FindIME() {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
                != PackageManager.PERMISSION_GRANTED) {
            // your READ_PHONE_STATE permission yet not granted.
            DevicePermission();
        } else {
            // your READ_PHONE_STATE permission is already been granted.
            ActivityCompat.requestPermissions(FlashScreen.this, new String[]{Manifest.permission.READ_PHONE_STATE}, PERMISSION_READ_STATE);
            GetIME();
        }
    }

Here we need to ask for user  permission

private static final int MY_PERMISSIONS_REQUEST_READ_PHONE_STATE = 0;
private void DevicePermission() {
        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.READ_PHONE_STATE)) {
   
       new AlertDialog.Builder(FlashScreen.this)
                    .setTitle("Permission Request")
                    .setMessage(getString(R.string.permission_read_phone_state_rationale))
                    .setCancelable(false)
                    .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            //re-request
                            ActivityCompat.requestPermissions(FlashScreen.this,
                                    new String[]{Manifest.permission.READ_PHONE_STATE},
                                    MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
                        }
                    })
                    .setIcon(R.drawable.ic_login)
                    .show();
        } else {
            // READ_PHONE_STATE permission has not been granted yet. Request it directly.
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE},
                    MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
        }
 }

public void GetIME() {
        String deviceUniqueIdentifier = null;
        TelephonyManager tm = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
        if (null != tm) {
            deviceUniqueIdentifier = tm.getDeviceId();
        }
        if (null == deviceUniqueIdentifier || 0 == deviceUniqueIdentifier.length()) {
            deviceUniqueIdentifier = Settings.Secure.getString(this.getContentResolver(), Settings.Secure.ANDROID_ID);
        }

        IME_Device = deviceUniqueIdentifier;
        Log.i("Device Ime", "Value--------->" + IME_Device);
     
    }

@Override
 public void onRequestPermissionsResult(int requestCode,
 String permissions[], int[] grantResults) {
        switch (requestCode) {

            case MY_PERMISSIONS_REQUEST_READ_PHONE_STATE: {

                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // permission granted!
                 
                    GetIME();
                } else {
                    // permission denied
                    Toast.makeText(mContext, "Need to allow Read Phone state ..", Toast.LENGTH_LONG).show();
                }
            }
            break;

            case PERMISSION_READ_STATE: {
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    // permission granted!
                 
                } else {
                    // permission denied
                    Toast.makeText(mContext, "Need to allow Read Phone state ..", Toast.LENGTH_LONG).show();
                }

            }
            break;
        }

Device's Estimated Battery Time calculation

How to Calculate Android Estimated Battery Remaining Time. 

within your AppCompatActivity

need to do register Battery change event listener with BroadcastReceiver like  

this.registerReceiver(this.mBatInfoReceiver, 
new IntentFilter(Intent.ACTION_BATTERY_CHANGED));

Now you need to declare with Activity or where you need BroadcastReceiver 

int expectedlevel;
boolean isFirstAllow = true;
int second;

String strFirstTime,strSecondTime;

private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver(){
    @Override    public void onReceive(Context ctxt, Intent intent) {
        
        int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0);

        SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
        Calendar c = Calendar.getInstance();

        if(isFirstAllow) {

            String formattedDate = format.format(c.getTime());
            strFirstTime  = formattedDate;

            expectedlevel = level - 1;
            isFirstAllow = false;
            second = new Time(System.currentTimeMillis()).getSeconds();
        }

        if(!isFirstAllow && level == expectedlevel){

            strSecondTime  = format.format(c.getTime());

            Date d1 = null;
            Date d2 = null;

            try {
                d1 = format.parse(strFirstTime);
                d2 = format.parse(strSecondTime);

                //in milliseconds               
               long diff = d2.getTime() - d1.getTime();

                long diffSeconds = diff / 1000 % 60;
                long diffMinutes = diff / (60 * 1000) % 60;
                long diffHours = diff / (60 * 60 * 1000) % 24;
                long diffDays = diff / (24 * 60 * 60 * 1000);

                System.out.print(diffDays + " days, ");
                System.out.print(diffHours + " hours, ");
                System.out.print(diffMinutes + " minutes, ");
                System.out.print(diffSeconds + " seconds.");

       // Now again we need percentage * difference time  = total long time value.
                long totalMinues =  diffMinutes * expectedlevel;
                long totalSecond  = diffSeconds * expectedlevel;
                long converttoMinutes = totalSecond/60;
                long addedAllMinues = totalMinues + converttoMinutes;

                // Now convert total minitues to millisecond;                
                 long AllMillisond = addedAllMinues * 60000;
     // Now Again convert this total Millisond to hours,minutes, second
                // for Battery Hours;
                long FinaldiffSeconds = AllMillisond / 1000 % 60;
                long FinaldiffMinutes = AllMillisond / (60 * 1000) % 60;
                long FinaldiffHours = AllMillisond / (60 * 60 * 1000) % 24;
                long FinaldiffDays = AllMillisond / (24 * 60 * 60 * 1000);

                System.out.print(FinaldiffDays + " days, ");
                System.out.print(FinaldiffHours + " hours, ");
                System.out.print(FinaldiffMinutes + " minutes, ");
                System.out.print(FinaldiffSeconds + " seconds.");
