Android-custom Notification

For the message in the message bar on June 23, Android enthusiasts know exactly what it is. For example, if we download an application, it may push some messages to our mobile phone at regular intervals, for example, a message may be displayed in the notification bar when it is delivered. This blog post introduces how to customize a Notification, which is very simple. Here, the little witch just sorts it out and provides a demo.
First, let's take a look at: Release/release + Mjk5NDAyMTMzo6jSxravv6q3or/release/xo6zQoc23z/gjrlhqzokjrm1_n21ykos1rg907 + release "brush: java. wwj. custom. notification; import android. app. activity; import android. app. notification; import android. app. icationicationmanager; import android. app. pendingIntent; import android. content. context; import android. content. intent; import android. graphics. bitmapFactory; import android.

FLAG_AUTO_CANCEL; // automatically disappears after the notification is clicked // 4 send the notification nm. notify (100, notification);}/*** New Method for customizing the Notification method *. The test on the mobile phone will crash. If not, you can continue to use the old build method.

Y (110, notification); // 2 build Notification // Notification notification2 = new notification (R. drawable. jay, "tiantuo game", // System. currentTimeMillis (); // 3 set the notification Click Event // Intent intent2 = new Intent (this, MainActivity. class); // PendingIntent contentIntent2 = PendingIntent. getActivity (this, 100, // intent2, 0); // icationication2.setlatesteventinfo (this, "", "", // contentIntent2 ); /// notification2.flags = Notification. FLAG_AUTO_CANCEL; // automatically disappears after the notification is clicked //// 4 send the notification // manager. notify (100, notification2 );}}

A little bit, we all know that the Android SDK version changes and the API will follow. Each version of the API may add or delete some interfaces, when using Android to provide some methods for our developers, we need to pay attention to the differences between versions. If we use a later version of the API, it may cause some errors, if a lower version is used, it may not be applicable in development. It is the minimum guarantee that the program will not crash. What APIs can be used to implement the functions of the program.
