App upload on Google Play 2014

Uploading APK sounds simple task but need more work and attention.

                                      Before Uploading Android app to Google Play

   Points to keep in mind before uploading the .apk file to Google Play are,

Core of App  Must be sure, the complete app/core of the app is developed and tested well. Check whether the app satisfies the requirements. Code Review Once the app is developed as per the requirement then it is the time for Code Review. Because code review will give the chance for reducing coding, performance optimization, and memory optimization etc. Tools are available for this PMD and Find Bug.

Log in Android

Trace Android Issues


The Android logging system provides a mechanism for collecting and viewing system debug output. Logcat dumps a log of system messages, which include things such as stack traces when the emulator throws an error and messages that you have written from your application by using the Log class. You can run LogCat through ADB or from DDMS, which allows you to read the messages in real time.

This is like System.out in java or printf in C language.

Where ever you want to trace the values you can use this.

Types of logs:

* Verbose - v(String , String)
* Debug    - d(String , String)
* Info        - i(String , String)
* Warning - w(String , String)
* Error      - e(String , String)

We can also able to filter them.


int A = 10;
Log.d(this.toString,"Current Value of A "+ A);

The above code will produce 10 as answer.

Fundamentals of Android

These are the basic building blocks for android  

 * Activity

Example:        Listening Music is the service. Because no user interaction is neccessary to play music. Once you start it will playing all the songs. Content Provider A content provider manages a shared set of application data. You can store the data in the file system, an SQLite database, on the web, or any other persistent storage location your application can access. 
Example:        Consider that you are going to develop message sending application. For choosing the contacts you need to add contacts one by one in your application.     …
