Best Practices Android - GoforExam.inBest Practices - User input

Every text field is intented for a differnet job. For example, some textfields are for text and some are for numbers. If it is for numbers then it is better to dispaly the numeric keypad when that textfield is focused. Its syntax is.

<EditText 
          android:id="@+id/phone" 
          android:layout_width="fill_parent" 
          android:layout_height="wrap_content" 
          android:inputType="phone" />

Other then that if your field is for password , then it must show a password hint , so that the user can easily remember the password. It can be achieved as.

<EditText 
         android:id="@+id/password" 
         android:hint="@string/password_hint" 
         android:inputType="textPassword" />

Best Practices - Background jobs

There are certain jobs in an application that are running in an application background. Their job might be to fetch some thing from the internet , playing music e.t.c. It is recommended that the long awaiting tasks should not be done in the UI thread and rather in the background by services or AsyncTask.

ASYNCTASK VS SERVICES. 
Both are used for doing background tasks , but the service is not affected by most user inteface life cycle events, so it continues to run in circumstances that would shut down an AsyncTask.

Best Practices - Performance 
Best Practices


Your application peformance should be upto the mark. But it should perform differently not on the front end , but on the back end when it the device is connected to a power source or charging. Charging could be of from USB and from wire cable.
When your device is charging itself , it is recommended to update your application settings if any, such as maximizing your refresh rate whenver the device is connected. It can be done as this.

IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED); 
Intent batteryStatus = context.registerReceiver(null, ifilter); 
// Are we charging / charged? Full or charging. 
int status = batteryStatus.getIntExtra(BatteryManager.EXTRA_STATUS, -1); 
// How are we charging? From AC or USB. 
int chargePlug = batteryStatus.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);

Best Practices - Security and privacy

It is very important that your application should be secure and not only the application , but the user data and the application data should also be secured. The security can be increased by the following factors.
1. Use internal storage rather then external for storing applications files
2. Use content providers wherever possible
3. Use SSl when connecting to the web
4. Use appropriate permissions for accessing different functionalists of device
