BTS Invasion

BTS Invasion

BTS – Korean band

On my last Osaka weekend, every hotel was booked. The only remaining rooms were super expensive. The reason? BTS was planned to arrive in town to have a concert, and the fans gathered around from all the surroundings (including Korea).

So, what is so special about BTS? They came to the conclusion that love cannot be sourced by the good rules implemented in society (true). They become rebellious in their search of genuine love or because they didn’t find it in the structure of the culture.

Lots of teenagers are seeking for genuine love in this part of the world, and see in BTS a possible outcome. The group offers an alternative approach to life.

I want to love myself? What about loving others? This is like saying ‘I dont have the inner resources to love others, so I quit early on this idea and at least I can love myself without carrying about others.

Good rules are good. But they don’t provide love. They are not a final end in themselves. God is love, the only true source of genuine love. The good rules are there to differentiate between good and evil. God is the source of love, the power that supports humanity to stand against evil.

Be A Good Programming Teacher

Be A Good Programming Teacher

Being a good programming teacher is a challenge. I worked for a few months at a company where I had to learn an in-house software solution from scratch.

The problem was that we did not have enough documentation and we had to rely on help from other colleagues.

Only a few people in the company were able to teach well. Not everyone is a good programming teacher.

One reason someone isn’t a good programming teacher is that they don’t like to share information with others (knowing more than others can make them feel superior, like they have an advantage).

Patience is important also, not only in solving programming errors but in teaching programming also. Some people don’t have the necessary skills to have patience with others.

Teaching someone is being unselfish and wanting the person next to you to succeed. Some people cannot rejoice when others succeed.

Being a good programming teacher is not something that you can learn. It is more than that.

It means you have special qualities that enable you to be a good programming teacher and to enjoy teaching.

It’s very important how you relate to other people

This world needs good teachers!

Easter Quiz

Easter Quiz

This is my final Udacity Project for Android Beginner Course:

This is an updated version of the UI

This is the java source code:

package com.catalinwk.android.eastersundayquizz;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Toast;
import android.widget.EditText;
import android.widget.CheckBox;
import android.widget.RadioButton;
import android.view.*;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

/**
* This method calculates the result of the quiz
*/
public void quizResults(View v){
int score = 0;

//first question
RadioButton radioSelectionQuestion1 = (RadioButton) findViewById(R.id.question_1_a);
if (radioSelectionQuestion1.isChecked())
score += 1;

//second question
CheckBox a = (CheckBox)findViewById(R.id.question_2_a);
CheckBox b = (CheckBox)findViewById(R.id.question_2_b);
CheckBox c = (CheckBox)findViewById(R.id.question_2_c);
if (a.isChecked() & b.isChecked() & c.isChecked())
score += 1;

//third question
RadioButton radioSelectionQuestion3 = (RadioButton) findViewById(R.id.question_3_b);
if (radioSelectionQuestion3.isChecked())
score += 1;

//last question
EditText textField = (EditText)findViewById(R.id.question_4);
if (textField.getText().toString().contentEquals(“life”))
score += 1;

//displayint toast message
CharSequence toastText = “You have scored ” + score + ” out of 4 questions”;
int duration = Toast.LENGTH_SHORT;

Toast toast = Toast.makeText(getApplicationContext(), toastText, duration);
toast.show();
}
}

Understanding Android Api Levels

Understanding Android Api Levels

I have installed the android system using an Udacity Tutorial and then I wrote my first Hello World Application with their help. It was great to see my first app running – it gives you courage to go further in the Android world. Everything went fine until I got an error saying: Nou resource found that matches the given name.

This is my xml code for layout:
TextView android:id="@+id/first_text"
android:text="Jesus is Risen!"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_above="@id/living_word"
android:padding="20dp"
android:textSize="36sp"
android:fontFamily="sans-serif-light"
android:background="#000000ff"
android:textColor="@android:color/white"

TextView android:id="@+id/living_word"
android:text="I am the light of the world: he that follows me shall not walk in darkness, but shall have the light of life"

As I was trying to position relative layouts and relate one view to another using ids, I got an error when compiling. In the editor everything was fine.
Error:(22, 31) No resource found that matches the given name (at 'layout_above' with value '@id/living_word').

The problem is that the compiler uses a different version of the SDK and the editor is unaware of this.
A solution is us the right Android API and SKD Tools:

Here is a description of the Android versions and API Levels:
https://developer.xamarin.com/guides/android/application_fundamentals/understanding_android_api_levels/

Each android devices supports exactly one version of API Level, identifying the libraries which are to be used for coding:
– the Target API level specifies the desired phone for the application
– the Minimum API level specifies the minimum API that can support the application

Android Studio USB Driver

Android Studio USB Driver

It is recommended to use your real phone to test android applications, instead of using the Android Simulator.
The Android Simulator is slow, using lots of resources.

To use your android phone you must first activate Developer options:

http://www.greenbot.com/article/2457986/how-to-enable-developer-options-on-your-android-phone-or-tablet.html

You must install a custom Android OEM driver from here:

https://developer.android.com/studio/run/oem-usb.html

Even if your phone is already installed on your system and you are able to download data from it, the Android Studio doesn’t work with a regular driver.
