This is yet another game like the 123Game . This game generates a single character which may be a Vowel, a Consonant, an Odd Number or may be an Even Number. The theme is you will get 3 seconds for each questions, you have to select the right option for it. If selected the right one then you will get 3 marks and the game gets over if u opt a wrong one ! Screenshots[Demo] The Code: For Generating Characters: void calc() { es="02468";os="13579";vs="AEIOU";ks="BCDFGHJKLMNPQRSTVWXYZ";k=""; Random rand=new Random(); k=k+es.charAt(rand.nextInt((4 - 0) + 1)); k=k+os.charAt(rand.nextInt((4 - 0) + 1)); k=k+vs.charAt(rand.nextInt((4 - 0) + 1)); k=k+ks.charAt(rand.nextInt((20 - 0) + 1)); String input=k; List<Character> characters = new ArrayList<Character>(); for(char c:input.toCharArray()){ characters.add(c); } StringBuilder output = new StringBuilder(input.length()); ...

This post will guide you to create a highly interactive 1+2=3 Game. This game is based on a simple logic. Basically you have 3 number 1,2,3 which will be shuffled each time with a randomly generated operator ( +,-,*,/ ) placed in between. Screenshots: Lets go through important section of the project. Code for fetching Highscore : public int chec() { SQLiteDatabase SQLiteDb = mh.getWritableDatabase(); String [] col1 = {"_id","score"}; int ch=0; Cursor cu1 = SQLiteDb.query("scr", col1, null, null, null, null, null); while(cu1.moveToNext()) { ch=Integer.parseInt(cu1.getString(1)); } return ch; } Code For Generating Expression : void calc() { String st="123",op="+-*/",z="",y=""; p=0; Random rand=new Random(); for(int i=0;i<3;i++) z=z+st.charAt(rand.nextInt((2 - 0) + 1)); for(int i=0;i<2;i++) y=y+op.charAt(rand.nextInt((3 - 0) + 1)); switch(...

This post will let you create a simple Color picker android application which will return the HEX code from the values set by R,G, and B labeled seekbars. In this application you can not only get the HEX value of the color generated but you can also set the color as the application background. This app is created by 3 seekbars and 1 EditText and 2 buttons. The value of the seekbars are extracted form the  getProgress() method. and the obtained values from R,G, and B are converted to hex using  toHexString() method and finally they are concatenated together for the HEX code of the RGB. Demo: The Hex Code generated when tapped on the generate Button The Background Color changes with corresponding value of Hex code when tapped on Set It  Lets have a glimpse on the basic concepts of the MainActivity.java Fetching values from the Seekbars r=sb1.getProgress(); g=sb2.getProgress(); b=sb3.getProgress(); Setting the value of the Hex Code box from ...
