how to send multimedia message on android

Background: You can start a message notification with activity and service, the difference being that one is triggered in the foreground and one is the background service. To use message notifications, you must use two classes: NotificationmanagerAnd Notification, other notificationmanager are initialized with the Getsystemservice method, and the Notify method is used to

Call and send text messages on the simulator. You can also use the emulator control of the ADT plug-in of eclipse on the command line. The specific method is as follows. Command line: Assume that the port number of the simulator you are currently enabling (on the title bar of the simulator) is 5554. 1. Open the command line and enter Telnet localhost 5554 and press Enter. The following prompt is displayed, indicating that you have successfully connec

Android Asynchronous Message Processing Mechanism (1) basic use of Handler The Android UI is thread-safe. If you try to perform UI operations in the Child thread, the program may crash. The solution should be to create a Message object, and then use Handler to send it out, a

In our common systems, the program usually works in two ways: event-driven and message-driven. In Android systems, Java applications work by message-driven. The message-driven principle is:1. There is a message queue that can deliver messages to this queue;2. There is a

Just learn Android soon, recently Micaela sent me a video, is how to make Android phone SMS transmitter, on the one hand I feel very interesting, the other side can accompany her together, today finished, special to summarize, although said relatively simple, but there is a summary of the necessary.SMS transmitter is mainly used for Android text messages sent, th

Speaking of handler in Android, let's first talk about the mechanism and principle of handler.1. Handler mechanism Principle Handler:It is mainly used to process sending and receiving messages. It is used to add messages to a specific logoff message queue and distribute and process messages in the queue. You can specify a logoff object when constructing a handler,Through the handler object, we can encapsul

mechanism.Therefore, the asynchronous processing mechanism of handler in Android can provide users with a more reasonable and user-friendly experience. Of course, Android is used handler to achieve, other platform environment, also has its own set of asynchronous implementation mechanism, the same principle, the name is different.Now that we're doing Android, we

As we all know, the call to other programs in Android for related processing, almost all of the use of intent, so, email is no exception.In Android, there are three types of intent called email:Intent.action_sendto Send without attachmentsIntent.action_send Send with AttachmentIntent.action_send_multiple

Android message mechanism A lot of previous knowledge is always forgotten. It seems that I have not fully understood it, and I hope to record it in the form of a blog. Speaking of the android message mechanism, we have to mentionHandlerIts Chinese meaning is the controller and processor.The Handler documentation on

We all know that calling otherProgramAlmost all intent is used for related processing. Therefore, email is no exception. In Android, there are three types of intent for calling Email:Intent. action_sendto send without attachmentIntent. action_send send with attachmentIntent. action_send_multiple send with multiple at

Message: messages, which contain message IDs, message processing objects, and processed data, are unified by MessageQueue, and eventually handled by handler. Handler: Processor, responsible for message delivery and processing. When using handler, you need to implement the Handlemessage (

First say why you need handler:The main thread of Android is also called the UI thread, which handles UI -related time. Android only allows UI components to be modified in the main thread, and when we need to modify the UI interface in other threads, we need to send a message to the main thread, The main thread then h

I believe that everyone on the Android handler is familiar, but to know, handler on its own is only a shell, the real role in the internal function is the message class, for message this class, I believe we will not be unfamiliar, As you often use the Message.obtain () method. But do you know what the obtain () method does for us, and below I will lead you to the

Since the broad application of the framework, we do not have to deal with naked mobile phone operating system APIs and do repetitive, complex, and meaningless things. However, there is no free lunch in the world. We still need to learn how to use different frameworks efficiently and correctly. Many methods to deal with a specific problem are different in different frameworks. Today, we mainly learn how to use andorid framework. In Android, the lower l

Using Android to send text messages, you need to first add the send, read the text message new permissions:　　　　 uses-permission Android:name = "Android.permission.RECEIVE_SMS" /> uses-permission Android:name = "Android.permission.SEND_SMS" />Then need to add a two edittext in the interface, to ad

Use PHP message queue for Android and Web communication Requirement Description: Android sends data to a Web page. System: Ubuntu 14.04 + apache2 + php5 + Android 4.4 The idea is to send an event through socket + Message Queue + s

your Android program, when a new Thread is created or executed, the Message Loop is not automatically created.Android does not have the Global Message Queue data structure. For example, objects in different APK cannot exchange messages through the Massage Queue ).For example, the Handler object of thread A can transmit messages to other threads so that other thr

? Google's internal comments are truly reliable. 1) The user defines the message identifier so that the system can identify what the current message is about. Each Handle has its own namespace for its own message identifier. Therefore, we do not have to worry about conflicts between Handler. 2) The second parameter has the same meaning as the third parameter, whi
