Before you begin,
You must know basic programming language like JAVA because android is most base on java.
secendly you must have a little bit expireence on XML.cos these two are significient for ANDROID programming,
Lets start........


step 1:
download java development kit(JDK) from oracle site...here is the link

This site is

• Use nested if else rather then all If statements.
• Use small integer size
• For or the condition most likely to be true place at left and for && condit most likely t be false place at left
• For(int i=0;i<bla ;i++); the loop will continue to work
• Do pass arguments by reference. Object s as reference
• Initialize the array at program time rather then at run time
• Use static with the array if u do not want it to be destroyed and reinitialize
• Use const if u do not want th e original array to b emodified
• If  there is only a single function which uses another call to the function then u need to proto type that function in this one for example

• Th e above mentioned way should be used.
• Passing the arrays and the pointers are interchangeable cuz if u pass an array to a function a pointr would be passed.
• The sizeof an array is the total bytes occupied by the array elements.
• If u want to do pointer arithmetic then do it only on an array
• Do not dereference the void pointers
• Initialize the array of function pointers the same way u initialize the other arrays
