This is the basic principle. You can even use the above principles to add some functions to delete friends. For example, when a user clicks to delete a friend, a special message is sent to the deleted object, the other party receives the message and deletes the message.
I believe that after everyone understands the principle, this example instantly changes from high to low. This Nima, so easy, no one will ~~~
3. Core code analysis
Because the amou
Notification is the SystemUI part, and the status of notification control is in the following file:
Frameworks \ base \ packages \ SystemUI \ src \ com \ android \ systemui \ statusbar \ tablet \ TabletStatusBar. java
The disable () method in the TabletStatusBar. java file is disabled.
To disable notification response
is not a proper choice for developers.
Since this road is not easy to go, is there any other convenient choice? The answer is yes, and it is easy to implement. Let's look back. Since it is not easy for the server to find the client, but it is easy for the client to find the server, the message push process can be reversed. First, the client regularly accesses the server and establishes a connection (usually an HTTP request ). Then, the server can ea

Androidpn integrates asmack on the client. In this way, you can easily establish a socket connection with the server based on the XMPP protocol. In the androidpn client, the connection management class is xmppmanager, which is
, Google also provided a push method similar to Apple later. Not plagiarism. After all, there is no particular innovation in Apple's overall technological implementation.User battery?Apps developers will not consider it at the system level. He assumes that other Apps are less "unconscious ". What Google does not force is:No one is really responsible for the user's battery.However, Google's solutions are not all tragedy:Because the entire technical sol

1. Message push mechanismThe server needs to be changed from passive to active, notifying the customer of information that the developer deems important, whether or not the application is running or disabled.
I thought of a sentence: don't call me, I will call you!

Android provides several common methods to push and receive messages:
1. Round Robin: ApplicationProgramYou should establish connections with the server in stages and check whether new messages arrive. You must implement communication with the server yourself, such as Message Queuing. In addition, you also need to consider the polling frequency. If it is too slow, it may lead to delay of some messages. If
The following example assumes that Google's GCM has been configured.

Some people say that programmers are quiet, but I don't fully agree that the noise of programmers is hidden behind the code and behind the program.This article is a must-have knowledge for android Developers. It is specially compiled and summarized for everyone. It is not perfect but useful.
