Aidl,There are 2 things to do: 1. Introduction of AIDL related classes.; 2. Call the class generated by the Aidl.How to create a aidl:The AIDL syntax is simple and can be used to declare an interface with one or more methods, or to pass parameters and return values. These parameters and return values are not of any type because of the need for remote calls.Here are some of the data types supported by Aidl:1. Simple Java programming language type (Int,boolean, etc.) that does not require import

important function is implemented by c,c++.Application framework: Application framework layer, the API that Android provides to usApplications: mobile app.Call Example: There is an alarm app under applications, and you want to respond by invoking some APIs from the application framework that actually call libraries's media framwork. Then call the driver for the sound card in the Linux kernel. The final horn will ring up.Android Runtime: Runs in the Dalvik VM and requires the support of the core

three fields, meaning, we look at the gaze is clear.Next, we'll look at a little demo to see how to implement the Register function in JNI and then load it into use by the DVM.1) Define a native method on the Java side, such as the following:public class Dynreg {public native static String SayHello ();}2) Create the corresponding C file in the JNI layer, this time, we do not need to generate the use of Javah generated header files and so on, and then

General simple question 1. is the process of Android dvm the same concept as that of Linux? DVM refers to the Virtual Machine of dalivk. Every Android application runs in its own process and has an independent Dalvik Virtual Machine instance. Every DVM is a process in Linux, so it can be considered the same concept. 2. What is the role of the SIM card EF file? Si

This article is reproduced. I hope my friend has a good interview question to study ...... 1. Check whether the process of Android DVM is the same concept as that of Linux. DVM refers to the Virtual Machine of dalivk. Every android application runs in its own process and has an independent Dalvik Virtual Machine instance. Every DVM is a process in Linux, so it ca

follows: it is an asynchronous class that can be canceled; that is, it has start and cancel operations, in fact, the above three threads also have corresponding close operations, but some may not need to be managed by developers. 3timer Timer is a timer that regularly triggers the corresponding action. 4. multi-thread File Download This implementation process uses the basic Thread class, which is displayed in the background. Five other threads (not manually started by developers) Webviewcoret

[Interview Questions] Android interview questions, questions android questions Android interview questions The interview questions collected on the Internet are a good supplementary study of Android theory! 1. Whether the process of android dvm is the same concept as that of Linux: A: dvm is a dalivk virtual machine. Every android application runs in its own process and has a dalivk Virtual Machine instan

main reason is that Android is using Dx.jar to optimize the initial class file when it is packaged, so that the generated Dex file is no longer a standard JVM executable, but a DVM executable file. The DVM and JVM are based on registers and one stack-based on the schema. Therefore, in the process of conversion, there must be a loss of information. Since the conversion is imperfect, there is a place for us

1.Android the process of DVM and the process of Linux, whether the application process is the same concept:A: DVM is a dalivk virtual machine. Each Android application runs in its own process and has a DALIVK virtual machine instance. And each DVM is a process in Linux. So it can be considered the same concept.What kinds of animations are there in 2.android? What

frame layer"4" Top Application layerThe difference between a 4.Dalvic VM and a JVM JVM converts Java source code to bytecode The DVM Android app is also written in Java, Google has done a Java virtual machine, due to copyright. Google Engineering died to turn all the. class files into a. dex file, so that the speed was increased and there was a schema-based difference. The traditional Android program runs under the

required List, map, and parcelables types, which contain data members that can only be simple data types, such as string other than the supported types. (In addition: I did not try to Parcelables, compiled under the Eclipse+adt, but perhaps in the future will have some support13, the process of DVM and the process of Linux, whether the process of the application is the sameThe DVM process is the D

This article describes the memory caching techniques for images: using LRUCache and soft references1. Soft referenceWe typically use memory to cache images by using the HashMap collection to save the URL of the image and the bitmap object of the image., but when we need to cache a lot of images, then the problem is, because the map contains a strong reference to the bitmap object,All garbage collection mechanisms that result in a DVM virtual machine c

declaration 2. String, Charsequence does not require a special declaration of 3. List, map, and parcelables types, and the data members contained within these types can only be simple data types, string, and other than supported types. (also: I did not try to parcelables, compile under Eclipse+adt but, maybe later support 13, DVM process and Linux process, application process is the same concept The DVM
