Answer 1

Make sure JSON is valid as the answer above. In case of any special characters you will need to escape them, i.e.

\" instead of "

Answer 2

Your json is not valid. Check it @ http://jsonlint.com/

It should be

[   // json array node
    {  // json object node
        "abc": { // json object abc
            "name": "andy", 
            "blood": "o+",
            "ge": 45
        }
    }
]

Parsing

JSONArray jarray = new JSONArray("your jsonstring");
for(int i=0;i<jarray.length();i++)
{
JSONObject jb = (JSONObject)jarray.get(i);
JSONObject jb1 = jb.getJSONObject("abc");
String name = jb1.getString("name");
// similarly blood and use getInt for ge
}

Edit:

Change your json to below and use the below you will get all values

String jsonstring ="{"
        +"abc"+": ["
            +"{"
               + "Fesa"+":"+ "englishisgood"
            +"},"
            +"{"
                +"Fesa"+":"+ "myenglishisnotsoaccurate"
            +"},"
             +"{"
               + "Fesa"+":"+ "germanisverynicelanguage"
            +"}"+","
            +"{"
                +"Fesa"+":"+ "mygermanisabsolutelygood"
            +"},"
            +"{"
                +"Fesa"+":"+ "cricketisaverypopulargame"
            +"},"
            +"{"
                +"Fesa"+":"+ "cricketislifeforindian"
            +"},"
            +"{"
                +"Fesa"+":"+  "hockeyistheoriginalgameforindia"
            +"},"
            +"{"
                +"Fesa"+":"+  "hockeyneedstoimprove"
            +"},"
            +"{"
                +"Fesa"+":"+  "computerisaveryfunctionaldevice"
           +"},"
           +"{"
                +"Fesa"+":"+  "computerisveryhelpfultomankind"
            +"},"
        +"]"+
    "}";

Parsing

    try
    {
    JSONObject jsb = new JSONObject(jsonstring);
    JSONArray jarray =jsb.getJSONArray("abc");
    for(int i=0;i<jarray.length();i++)
    {
    JSONObject jb = (JSONObject)jarray.get(i);
    String name = jb.getString("Fesa");
    Log.i("..........",name);
    Toast.makeText(getApplicationContext(), name, 1000).show();
    }
    }catch(Exception e)
    {
        e.printStackTrace();
    }
