A simple click on the Readability button and TADAAA:

After Readability is turned on

You can also adjust the font size, width and color theme to your liking.

Give it a try, you will definitely like it.

We measure the rendering in FPS which stands for frames per second. If we have 30FPS that means that we display 30 images every second. For a mobile device 30 FPS is great so we will aim for that.

Just imagine someone walking and close your eyes for exactly one second. After opening your eyes you will see the person in the position after one second. This is a 2FPS.

I never thought it could be explained this way! haha

Anyway, the posted link as above gives a good overall idea and implementation on how to develop a game (surface view is used, main game loop to update the UI running on another thread etc).

Sqlite database on your Android emulator

1.Create it in onCreate() when your app first launched:

According to Using Databases | Android developer:

The recommended method to create a new SQLite database is to create a subclass of SQLiteOpenHelper and override the onCreate() method, in which you can execute a SQLite command to create tables in the database

There’s a sample coding on how to populate the DB programmatically here at the Data Storage| Android developer.

2. Create the sqlite database on your PC and adb push it to your emulator.

- Use the Android Debug Bridge (adb) pull/push to retrieve a copy of the database on your   Android emulator, populate it and put it back on the emulator.

• Fire up your emulator.
• Open up your command shell (Start -> Run -> type in cmd):

Your database will be stored in data/data/<package name>/databases/<db name of your choice>

The full command as the screenshot above is:

adb pull data/data/com.chien.programmersquote/databases/quote local_database

‘quote’ is the DB that is stored on the emulator and obviously local_database is the DB file name I will be downloading my database to at C:\users\Sted\

After that you could manipulate the DB using one of the tools available freely, namely the firefox addon, Sqlite Database Browser,  SqliteSpy.

In the emulator you can access these database files directly; when connecting to a real phone however you will need root access to access the database files directly.

3. Import/Export via DDMS from Eclips

Inside Eclipse while the emulator is running, you can see your file hierarchy by going to Window -> Show View -> Other.. -> Android -> File Explorer ( or just click on the DDMS icon)

It took me some time to figure out the there are 3 buttons here on the DDMS page that serves as adb pull, adb push and delete file.  Navigate to your database at data/data/<package name>/databases/ and just click on the button to either download / upload / delete the database.

Hope it helps. Ways described above are just generally some ways to deal with populating the database on your emulator for testing purposes.

Weird enough, it’s packed as a jar file under the /lib folder in the Android sdk.

Execute this in your command prompt and you should get your hierarchy view up and running.

java -jar ./lib/hierarchyviewer.jar

Note that you need to add the Java interpreter java to the System Variables->PATH to execute the above script.

After that, you could create a .bat file(put the above one line command in the .bat file) and put it in your tools folder to fire up the hierarchy view(with lesser typing).
