Convert String to Bitmap and Bitmap to String

In android, Normally we send and receive data in the form of string.So if we have image in the Bitmap form then we can not send it to server.So here i made a simple function that you need pass bitmap and it will return a string.


       public String BitMapToString(Bitmap bitmap){
            ByteArrayOutputStream ByteStream=new  ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG,100, ByteStream);
            byte [] b=ByteStream.toByteArray();
            String temp=Base64.encodeToString(b, Base64.DEFAULT);
            return temp;
      }

Here is the reverse procedure for converting string to bitmap but string should Base64 encoding


      public Bitmap StringToBitMap(String encodedString){
     try{
       byte [] encodeByte=Base64.decode(encodedString,Base64.DEFAULT);
       Bitmap bitmap=BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
       return bitmap;
     }catch(Exception e){
       e.getMessage();
       return null;
     }
      }

Improve your concentration while developing "Mobile Application"

Hello Friends!

Being software developer is a pain full situation when we want to focus but fail to focus. In most cases we misjudge our ability and caliber. We start criticize our self for what we should responsible. We forget that we are human being and we born to commit mistakes. We born to learn from our mistake. As a mobile application developer, i have gone through the same situation many times. Every time i try to avoid with some set of rules and principles that worked for me. So let share with each among us

Always leave on time
Generally people thinks that working for longer hours will increase your performance at works. But it never does as i feel. Developing a software is not physical work, so you can not work until your mind is not active. Sitting for more hours will drain your brain and stop thinking. It need quality time rather than being sitting for longer hours. So try to leave on time, yes indeed if you need any urgency and have to work for client late then sitting for more hours does not harm. But it should be a fashion. leaving on time will make you more focus because you have to complete task with in the time

Plan one thing at a time
A CPU can execute million of calculation with in milliseconds but nothing is creative. We have a human mind, we have some limitation and some exceptional abilities. Give half an hour in morning for planning. Allocate task to yourself, divide expected time and start working. Do not spend too much time on a particular thing and continue work till the day end. Now observe what you have completed. If you fail to do something than find the reason, but do not switch on panic button.

Take short break
Stand up from chair every two hours. Take some walk for 2 minute, drink water and again start working. It will relax your brain muscles and boost your concentration for coming two hours. Believe it increase my output 20 %. And most importantly it reduce bug from software i made. In break you can talk to your colleague, it will help you to maintain healthy relationship. But do not misuse break. I call this break, break for bugs

Some Guide Lines while creating your own android application.

Hi Friends!

I am observing some regular mistake that make a good application to be in category of crap. From the last 15 days i am observing trend of Play store applications. On basis of all my observation and experience, I suggest you some tips to improve your application quality

we should do some home work which one necessity and universal truth to create one milestone in your career.


1. Avoid to use high quality Image - Using high quality image, limit available memory for your application. When we load image into memory, it take lots of memory and application heap size shrink drastically. And this becomes the main cause of crashing application. This is really bad experience. If your application really required image of high quality then you can scale them according to device heap size and density. Using image of 3000*4000 on 720*1280 resolution does not mean anything.

2. Shows proper Alert - Showing proper alert, is big boost to make user happy. I download one application which always show "Your connection is not available" either i have connection or my server does not respond with in time (while downloading application data).This make awkward as i was confused. So always keep related message in alert.

3. Release hardware - If you are using hardware like camera, Bluetooth then please release them properly after use is over. Most immense issue is of GPS if you are using GPS then remove update after use is over. Else it will drain user battery.

4. Use combination of Relative Layout and Density Pixel - Density Pixels (dp)  device independent pixel,which provide good design on phone with different densities. Relative Layout align child on relativity, so chances of hampering layout reduces. 

5. Always remember to close connection - Either you open data base or reading data from online URL, make sure you close all connection pointing to source. Close Input stream and data base connection when you read data. This will help you to avoid conflict and save your memory also.

6. Remove unnecessary permissions - Recently, I read review of my application. User raise one issue, why should one's allow to make phone call. I was surprised that my application never need this permission but i forgot to remove it from manifest and it cost me worse review. So never play with user, Take preventing measure and remove all permission that does not required. This is not common issue but sometimes we commit this by mistake. So double check your manifest permission.

And last but not least, if you have commit any mistake. Then do not need worry, upload a updated version of your application so that user will download your update version.

Now (Right to Left) support in Android 4.2

Android 4.1 (Jelly Bean) introduced limited support for bidirectional text in TextView and EditText elements, allowing apps to display and edit text in both left-to-right (LTR) and right-to-left (RTL) scripts. Android 4.2 added full native support for RTL layouts, including layout mirroring, allowing you to deliver the same great app experience to all of your users, whether their language uses a script that reads right-to-left or one that reads left-to-right.

If you do nothing, your app will not change — it will continue to appear as it currently does. However, with a few simple changes, your app will be automatically mirrored when the user switches the system language to a right-to-left script (such as Arabic, Hebrew, or Persian). For example, see the following screenshots of the Settings app:

To take advantage of RTL layout mirroring, simply make the following changes to your app:

Declare in your app manifest that your app supports RTL mirroring.

Specifically, add android:supportsRtl="true" to the <application> element in your manifest file.

Change all of your app's "left/right" layout properties to new "start/end" equivalents.

If you are targeting your app to Android 4.2 (the app's targetSdkVersion or minSdkVersion is 17 or higher), then you should use “start” and “end” instead of “left” and “right”. For example, android:paddingLeft should become android:paddingStart.

If you want your app to work with versions earlier than Android 4.2 (the app's targetSdkVersion or minSdkVersion is 16 or less), then you should add “start” and end” in addition to “left” and “right”. For example, you’d use both android:paddingLeft and android:paddingStart.

For more precise control over your app UI in both LTR and RTL mode, Android 4.2 includes the following new APIs to help manage View components:

android:layoutDirection — attribute for setting the direction of a component's layout.

android:textDirection — attribute for setting the direction of a component's text.

android:textAlignment — attribute for setting the alignment of a component's text.

getLayoutDirectionFromLocale() — method for getting the Locale-specified direction

You can even create custom versions of layout, drawables, and other resources for display when a right-to-left script is in use. Simply use the resource qualifier "ldrtl" to tag your resources, meaning “layout direction right-to-left”. To debug and optimize custom right-to-left layouts, HierarchyViewer now lets you see start/end properties, layout direction, text direction, and text alignment for all the Views in the hierarchy.

It's now easy to create beautiful Android apps for all your users, whether they use a right-to-left or left-to-right language. We look forward to seeing some great apps!

Formatting Android Layout XML & JAVA in Eclipse

Sometimes when you are editing Android Layouts in Eclipse, it makes more sense or is more convenient to change the actual xml content. The problem is, a lot of the time the xml is not pretty to look at. Lines of text often run off the screen and it is difficult to tell where one element begins and another ends.

Don't Worry

 Eclipse has some handy auto-formatting tools. Press Ctrl+Shift+F to auto-format the selected file. Or from the menu, click Source->Format.

Now your file will be cleaned up and easier to edit.

If you have text selected, only the selected text will be formatted. If no Text is selected, the entire file will be formatted. And Auto-Format will work on your Java files too.
