broadcastreceiver we just defined is mainly used to update the action_appwidget_update action, in addition, there are also action_appwidget_deleted, action_appwidget_enabled, and action_appwidget_disabled, which indicate the events triggered when the deletion is enabled, and disabled. The system broadcast is used here. We use the onreceive method of the broadcastreceiver class to capture.
The following Java broadcast action acquisition code is as follows:

Component name, action, data, category for a class, these 4 information determines which component Android will start, where Component name is used in explicit intent, action, Data, Category, Extras, flags are used in an implicit intent.B.

It is because Rjava is the underlying interface and is called using JNI as an interface, so it is very efficient. In the Jri scenario, the JVM loads the RVM directly through memory, and the call process performance is virtually lossless, mak

I wrote an Intent blog, mainly about Implicit Intent. Portal: Android-IntentIntent object structure
Component name, Action, Data, Category, Extras, FlagsComponent name
The Component name is the Component name of the Intent object to be processed.
The component name object is encapsulated by the ComponentName class. The component name contains the package name and class name and is declared in the AndroidManifest. xml file.
The c
data exists on the device and is controlled by the ContentProvider. However, if necessary, in addition to the Data URI, Data can also explicitly contain its MIME type.
You can use the setData () member function of the Intent class to set the data URI, use the setType () member function to set the data MIME type, or use setDataAndType () the member function sets the data URI and MIME types at the same time. You can use the getData () member function to retrieve the data URI and use the getType (
