Making your application’s data usage preferences available from system settings

Android 4.0+ gives users the ability to monitor the amount of mobile data being used on their device, and in some cases, automatically turn off mobile data.
You can access the Data Usage settings screen by opening the Settings app, and then selecting Data Usage.

In Android 4.0+ if you create a Preference Activity to allow users to modify your application’s data usage, you can make it available from within the system settings when a user inspects your application’s data usage.

It is very simple: just add a MANAGE_NETWORK_USAGE Intent Filter to the Preference Activity’s manifest node: 
<activity android:name=".PreferencesActivitySummary" android:theme="@style/AppThemeABS">
    <intent-filter>
         <action android:name="android.intent.action.MANAGE_NETWORK_USAGE"/>
         <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>            
</activity>
Once set, the View Application Settings button in the system settings will launch your Preference Activity, allowing users to refine your application’s data usage rather than restricting or disabling it.

AntiPattern: freezing a UI with Broadcast Receiver

Image
The worst thing that can happen to your app's responsiveness is an "Application Not Responding" (ANR) dialog. In android guidelines we can read: In any situation in which your app performs a potentially lengthy operation, you should not perform the work on the UI thread , but instead create a worker thread and do most of the work there. This keeps the UI thread (which drives the user interface event loop) running and prevents the system from concluding that your code has frozen. It's very important to understand what is Main Thread . When an Android app is launched, the system creates a thread for the application which is known as the main thread. If you run up any project under the debugger in Eclipse you will see the main thread. If your app ties up the UI thread for more than 5 seconds or a BroadcastReceiver does not complete within 10 seconds, Android will throw up the Application Not Responding (ANR) dialog which gives the user the opportunity t

NotificationListenerService and kitkat

Image
Android 4.3 (API 18) introduced NotificationListenerService . I published a post about it a few months ago. Android 4.4 (API 19) added new features, and now we can have a lot of extra info about a notification (before we need to use reflection to read some info). As in 4.3,to use the NotificationListenerService we have to extend the NotificationListenerService and implement onNotificationPosted() and onNotificationRemoved() methods public class SimpleKitkatNotificationListener extends NotificationListenerService { @Override public void onNotificationPosted(StatusBarNotification sbn) { //.............. } @Override public void onNotificationRemoved(StatusBarNotification sbn) { //.............. } } Then we must declare the service in the manifest file with the BIND_NOTIFICATION_LISTENER_SERVICE permission and include an intent filter with the SERVICE_INTERFACE action

How to centralize the support libraries dependencies in gradle

Working with multi-modules project, it is very useful to centralize the dependencies, especially the support libraries. A very good way is to separate gradle build files, defining something like: root --gradleScript ----dependencies.gradle --module1 ----build.gradle --build.gradle In gradleScript/dependecies.gradle : ext { //Version supportLibrary = '22.2.1' //Support Libraries dependencies supportDependencies = [ design : "com.android.support:design:${supportLibrary}", recyclerView : "com.android.support:recyclerview-v7:${supportLibrary}", cardView : "com.android.support:cardview-v7:${supportLibrary}", appCompat : "com.android.support:appcompat-v7:${supportLibrary}", supportAnnotation: "com.android.support:support-annotations:${supportLibrary}", ] } In the top level file build.gradle
