Enterprise Android Programming Android Database Applications for the Enterprise

The definitive guide to building data-driven Android applications for enterprise systems

Android devices represent a rapidly growing share of the mobile device market. With the release of Android 4, they are moving beyond consumer applications into corporate/enterprise use. Developers who want to start building data-driven Android applications that integrate with enterprise systems will learn how with this book. In the tradition of Wrox Professional guides, it thoroughly covers sharing and displaying data, transmitting data to enterprise applications, and much more.

• Shows Android developers who are not familiar with database development how to design and build data-driven applications for Android devices and integrate them with existing enterprise systems
• Explores how to collect and store data using SQLite, share data using content providers, and display data using adapters
• Covers migrating data using various methods and tools; transmitting data to the enterprise using web services; serializing, securing, and synchronizing data
• Shows how to take advantage of the built-in capabilities of the Android OS to integrate applications into enterprise class systems

Enterprise Android prepares any Android developer to start creating data-intensive applications that today’s businesses demand

Create screencast videos of you android apps

Hey there.

If you are a cheap ass like me and you dont want to spend any money on an android screencast app, I will tell you today how you can make a really cool video from your android apps with free software!

All you need is linux :)

Recording the android emulator
To record your screen you need istanbul.

• After you started it, you will notice a small icon on the upper right of your screen. 
• Do a right click on it and select "select window to record" and select your android emulator. 

• After this you can click on the icon to stat recording and do what ever you want with your app.
• If yo are finished, click again on the istanbul icon to stop it and save the video somewhere as "appvideo.avi".

Fixing your video
Istanbul has some problems, so you have to run the following command to fix the video file:
For this you need mencoder.

"mencoder appvideo.avi -ovc lavc -lavcopts vcodec=mpeg4:vpass=1 -oac copy -o appvideo_fixed.avi"

Cropping your video
After this step you are ready to get rid of the emulator screen around your video. This can easily be done using avidemux.

• Open avidemux and load the file "appvideo_fixed.avi"
• Now on the left under "video" select "copy" and set it to something like "MJPEG". 
• Select "Filter" and choose crop filter. You can now crop the emulator out of the video. Best settings for me are left: 20, top 20, bottom 20 and right 435.
• Now click save and you are done!

Upload your video to youtube and enjoy!

To fix all videos created by istanbul, use this script:

#!/bin/bash

FILES=*.avi

for f in $FILES

do

echo "Processing $f"

mencoder $f -ovc lavc -lavcopts vcodec=mpeg4:vpass=1 -oac copy -o "$f"_fixed

 

 # do something on $f

done

Learning C 6 Subprograms

I jus rewrote and corrected the code of the app from LESSON #4 because on run it had an error: "Segmentation fault (core dumped)". But I wanted to complicate it and I added a new function that transfor an array in a matrix and I worked with subprograms because I think its more clearly and nice. So, the same example:

Transformation from matrix to array:

1 2 3 4

5 6 7 8= A[3][4] where A.lin=3 and A.col=4 so => V.elem=3*4=12

9 0 1 2

So 

1 2 3 4 5 6 7 8 9 0 1 2= V.vector[12]

The formula is:

k=A.col*i+j 

Transformation from array to matrix:

1 2 3 4 5 6 7 8 9 0 1 2= V.vector[12]=> V.elem=12.=>

1 2 3 4

5 6 7 8=A[3][4]

9 0 1 2

The formulas are:

i=k/A.col and j=k%A.col

And the code is:

-----------------------------------------------------------------------------------------------

def.c

typedef struct{

double **matr;

int lin;

int col;

}Matrice;

typedef struct{

double *vector;

int elem;

}Array;

int i,j,k;

Matrice A,B; Array V;

-----------------------------------------------------------------------------------------------

functii.c

// citire matrice

void citire_matr(Matrice A){

     for(i=0;i<A.lin;i++)

                    { for(j=0;j<A.col;j++)

                                     scanf("%lf",&A.matr[i][j]);

     }

}

//afisare matrice

void afisare_matrice(Matrice A){

     for(i=0;i<A.lin;i++)

                     {for(j=0;j<A.col;j++)

                                     printf("%lf ",A.matr[i][j]);

                     printf("

                     }

     printf("

     }

//afisare vector

void afisare_vector(Array V){

     for(k=0;k<V.elem;k++)

                       printf("%lf ",V.vector[k]);

     printf("
");

     }

//transformare matrice->vector

void matr_vector(Matrice A, Array V){

      for(i=0;i<A.lin;i++)

                     for(j=0;j<A.col;j++)

                                     V.vector[A.col*i+j]=A.matr[i][j];

     }

//transformare vector->matrice

void vectortomatr(Matrice B, Array V){

    i=j=k=0;

    while(k<V.elem){

    B.matr[k/B.col][k%B.col]=V.vector[k];

    i++;j++;k++;

    }

}

-----------------------------------------------------------------------------------------------

#include<stdio.h>

              UpdateSystemSetting.setOnClickListener(newButton.OnClickListener(){

          @Override
          public void onClick(View arg0) {
           int SysBackLightValue = (int)(BackLightValue * 255);
           android.provider.Settings.System.putInt(getContentResolver(),
             android.provider.Settings.System.SCREEN_BRIGHTNESS,
             SysBackLightValue);
       
          }});
      BackLightControl.setOnSeekBarChangeListener(newSeekBar.OnSeekBarChangeListener(){

          @Override
          public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {
           // TODO Auto-generated method stub
           BackLightValue = (float)arg1/100;
           BackLightSetting.setText(String.valueOf(BackLightValue));
       
           WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
           layoutParams.screenBrightness = BackLightValue;
           getWindow().setAttributes(layoutParams);
          }
          @Override
          public void onStartTrackingTouch(SeekBar arg0) {
          }
          @Override
          public void onStopTrackingTouch(SeekBar arg0) {
          }});
          }
