Signing a First Version Apk using Cordova using Command Line:



1. Update the AndroidManifest. Open /myApp/platforms/android/AndroidManifest.xml and update. VersionCode is what will display in the store; versionName is for your internal use and won’t be shown: android:versionCode=”10000″ android:versionName=”1.0.0″ (Note on format: “10000” = 1.00.00.)

Make sure the following is accurate (change com.developerName.myApp to your own information here and throughout this page):

package="com.developerName.myApp"
Make sure the following is 11 or higher (I choose 19.):

android:minSdkVersion="11"
Open /myApp/config.xml and make sure the widget id and version are the same as in AndroidManifest.xml.

2. The following steps create your private key and the keystore file in which to store it. In Terminal, make sure your starting position is within your app’s root folder of /myApp and run the following. (To start commands from your app root folder in Terminal, open the Terminal app, type cd and a space, drag the /myApp folder to Terminal, tap in Terminal to activate its window, then hit Enter.)

keytool -genkey -v -keystore myapp.keystore -alias myapp -keyalg RSA -keysize 2048 -validity 10000
You’ll be prompted to answer several questions. Use only legal characters like letters and numbers, not punctuation. For 2-letter country code, look up this list: http://www.worldatlas.com/aatlas/ctycodes.htm

3. You will then review the data presented. At that point, if any of the information is wrong, type the two letters to re-enter that information. For instance, type cn to change your first and last name. Otherwise, confirm the information by typing “yes.” Then just hit Enter if the password for the following Terminal information will be the same as the previous.

Your keystore file will be located at /myApp/myapp.keystore. This needs to be copied to a safe place ASAP. Your customers will not be able to update to the next version without this file.

4. Copy myapp.keystore to /platforms/android.

Now it’s time to sign the app with the key and create the release version.

5. Open /platforms/android/local.properties (or project.properties) in a text editor.

6. Add these two lines at the end and save, even though it says, “Do not modify this file — YOUR CHANGES WILL BE ERASED!”

key.store=myapp.keystore
key.alias=myapp


7. Still in your /myApp folder in Terminal, run:

cordova build android --release
You’ll be asked for your password twice and it won’t be obfuscated.

8. Your myApp.apk file is put in /myApp/platforms/android/ant-build/CordovaApp-release.apk. (If not there, it may be in /myApp/platforms/android/build/outputs/apk.) This is the file you rename and upload to Google Play.

Signing an Update Version Apk Without Eclipse

This section assumes you’ve already created your keytool and keystore file from your first version, and have the keystore file in a safe place. You won’t follow those steps again.

1.Open /myApp/config.xml and update. Increment the version number.

2. In Terminal, make sure your starting position is within your app’s root folder of /myApp and run the following. (To start commands from your app root folder in Terminal, open the Terminal app, type cd and a space, drag the /myApp folder to Terminal, tap in Terminal to activate its window, then hit Enter.)

3. From your app’s root folder in Terminal:

cordova build android --release


SEE BELOW EXAMPLE :

C:\vissicomp>keytool -genkey -v -keystore myapp.keystore -alias myapp -keyalg RS

Advantages PL/SQL  :
  • Procedural Language Supported:PL/SQL is a development tools that not only supported data Manipulation but also Provide the Condition, Checking, Looping or Branching Operation.
  • Reduces Network Traffic:PL/SQL is same entire block of SQL statement execute to the oracle engine at all at once so it's benefit to reduce the Network Traffic.
  • Error Handling:PL/SQL also permits during with Error Handling as required facility to Display User Friendly Error Message where errors are encounter.
  • Declare Variable:PL/SQL allow to declaration and use of variable in a block of code which variable will use to store intermediate result of query for later processing.
  • Intermediate Calculation:PL/SQL calculations done quickly and efficient without the use of oracle engines and improve the transaction.
  • Portable Application:Application are written in PL/SQL is portable in any computer or hardware for any system means Application independence to run any computer.


PL/SQL Block:
PL/SQL Block consists of three sections:
  • The Declaration section (optional).
  • The Execution section (mandatory).
  • The Exception (or Error) Handling section (optional).

PL/SQL Block:
DECLARE
Variable declaration
BEGIN
Program Execution
EXCEPTION
Exception handling
END;
Basic example :
DECLARE
message varchar2(20):= 'Hello, World!';
BEGIN
dbms_output.put_line(message);
END;
PL/SQL DATA TYPE:
  • Number type
Example :
no    number:=10;
(The NUMBER datatype is used to store fixed-point or floating-point numbers)
  • Character type
(CHAR data type is used to store fixed-length character data)
Example:
grade  CHAR(1);
.VARCHAR2
(The VARCHAR2 data type is used to store variable-length character data)
.Datetime  type
(The Datetime data types lets us store and manipulate dates, times, and intervals (periods of time). )
 .Boolean type:
(BOOLEAN data type is used to store the logical values TRUE, FALSE and NULL (which stand for a missing, unknown, or inapplicable value).)
IF-THEN syntax:
IF condition THEN
{
...statements to execute when condition is TRUE...
}
END IF;

IF-THEN EXAMPLE:
declare
no number:=&n;
begin
if no>0 then
dbms_output.put_line('is positive');
end if;
end;
if-then-else syntax:
IF condition THEN
{
...statements to execute when condition is TRUE...
}
ELSE
{
...statements to execute when condition is FALSE...
}
END IF;

IF-THEN ELSE  EXAMPLE:

declare
no number:=&n;
begin
if no>0 then
dbms_output.put_line('is positive');
else
dbms_output.put_line('is negative');
end if;
end

IF-THEN-ELSIF-ELSE syntax:
IF   condition1    THEN
{
...statements to execute when condition1 is TRUE...
}
ELSIF   condition2   THEN
{
...statements to execute when condition2 is TRUE...
}
ELSE
{
...statements to execute when both condition1 and condition2 are FALSE...
}
END IF;
IF-THEN-ELSIF-ELSE example:
DECLARE
grade CHAR(1);
BEGIN
grade := 'B';

IF grade = 'A' THEN
DBMS_OUTPUT.PUT_LINE('Excellent');
ELSIF grade = 'B' THEN
DBMS_OUTPUT.PUT_LINE('Very Good');
ELSIF grade = 'C' THEN
DBMS_OUTPUT.PUT_LINE('Good');
ELSIF grade = 'D' THEN
DBMS_OUTPUT. PUT_LINE('Fair');
ELSIF grade = 'F' THEN
DBMS_OUTPUT.PUT_LINE('Poor');
ELSE
DBMS_OUTPUT.PUT_LINE('No such grade');
END IF;
END;

Case  example:
DECLARE
grade CHAR(1);
BEGIN
grade := 'B';

CASE
WHEN grade = 'A' THEN DBMS_OUTPUT.PUT_LINE('Excellent');
WHEN grade = 'B' THEN DBMS_OUTPUT.PUT_LINE('Very Good');
WHEN grade = 'C' THEN DBMS_OUTPUT.PUT_LINE('Good');
WHEN grade = 'D' THEN DBMS_OUTPUT.PUT_LINE('Fair');
WHEN grade = 'F' THEN DBMS_OUTPUT.PUT_LINE('Poor');
END CASE;
EXCEPTION
WHEN CASE_NOT_FOUND THEN
DBMS_OUTPUT.PUT_LINE('No such grade');
END;

WHILE Loop   syntax:
WHILE  condition
LOOP
{
...statements...
}
END LOOP;

WHILE Loop   example:
declare
n number:=1;
begin
while n<10
loop
dbms_output.put_line(n);
n:=n+1;
end loop;
end;


For loop syntax:
FOR  loop_counter IN [REVERSE] lowest_number..highest_number
LOOP
{
...statements
...}
END LOOP;

For loop example:

declare
i number;
begin
for i in 1..10
loop
dbms_output.put_line(i);
end loop;
end;


Cursor   in Oracle:
create  table mytest
(id   int,
name varchar(200));
then insert values and use following code to learn.
for example:
insert into mytest values(1,'om');
then use following to learn cursor...
(1)simple way  select statement in pl-sql :
declare
enoint;
enamevarchar(200);
begin
select  id,name into eno,ename  from mytest where id='1';
dbms_output.put_line(eno||ename);
end;
(2) SELECT   USING     %TYPE:
declare
enomytest.id%type;
enamemytest.name%type;
begin
select  id,name into eno,ename  from mytest where id='1';
dbms_output.put_line(eno||ename);
end;

(3)cursor example  with %rowtype :
declare
en  mytest%rowtype;
cursor c1   is  select   *   from  mytest;
begin
open c1;
loop
fetch c1 into en;

dbms_output.put_line(en.id||en.name);

exit when c1%notfound;

end loop;
close c1;

end;



(4)cursor with %type example:
declare
enmytest.id%type;
enamemytest.name%type;

cursor c1   is  select   id,name   from  mytest  where id=1;
begin
open c1;
loop
fetch c1 into en,ename;

dbms_output.put_line(en||ename);

exit when c1%notfound;

end loop;
close c1;

end;


(5) parameterized     Cursor taking input from user(command line) :

declare
myno number;
cursor c1(en number)  is  select   *   from mytest where id=myno;
res  c1%rowtype;
begin
myno:=&en;
open c1(myno);

loop
fetch c1  into res;

dbms_output.put_line(res.id||res.name);

exitwhen c1%notfound;

end loop;
closec1;

end;
