Important Library for Android

Using Parceler

Although creating Android Parcelables is usually at least 10x faster than using Serializable, creating Parcelable objects requires creating a lot of boilerplate code in defining exactly the stream of data that should be serialized and deserialized as documented in this section.

All Size design scalable size unit

An android SDK that provides a new size unit - sdp (scalable dp). This size unit scales with the screen size. It can help Android developers with supporting multiple screens.
for text views please refer to ssp which is based on the sp size unit for texts.

dependencies {
  compile 'com.intuit.sdp:sdp-android:1.0.5'
}

Device ID

final TelephonyManager tm = (TelephonyManager) getBaseContext().getSystemService(Context.TELEPHONY_SERVICE);

final String tmDevice, tmSerial, androidId;
tmDevice = "" + tm.getDeviceId();
tmSerial = "" + tm.getSimSerialNumber();
androidId = "" + android.provider.Settings.Secure.getString(getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);

UUID deviceUuid = new UUID(androidId.hashCode(), ((long)tmDevice.hashCode() << 32) | tmSerial.hashCode());
String deviceId = deviceUuid.toString();


Log.e(TAG,"deviceId........."+deviceId);

Data Send in android

integer data send from activity to service

-------------Activity--------------

Intent serviceIntent = new Intent(this, StatusService.class);
serviceIntent.putExtra("QB_Friend_Id",QB_Friend_Id);
startService(serviceIntent);



----------------service-------------------




@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {
    // Let it continue running until it is stopped.
    if (intent != null && intent.getExtras() != null) {
        userID = intent.getIntExtra("QB_Friend_Id", 0);
        Log.v(TAG, "number........." + userID);
    }
