api key best practices

The steps are as follows: Prerequisites: Each Google Maps API Key corresponds to an MD5 fingerprint (fingerprint Certificate). That is to say, before obtaining the map API Key, you must use the keytool provided by Java JDK to generate an MD5 fingerprint. (Does sun have long known that Google will make such a thing? Why

Operating environment: VC6 SP5, Sp1,nt4 SP3. It is important to get a session key in the usual programming. However, Microsoft's cryptographic Operations API (either Basic or enhanced) does not provide this functionality. CryptExportKey () and Cryptimportkey () each require a valid key handle to encrypt and decrypt the session

The acquisition of the android map API is mainly to prepare for map development (a bit like nonsense .....) The specific functions are not described. Let's look at how to obtain them. 1. obtain your debug keystore location: Open eclipse ---> Windows ---> preferences ---> Android ---> buildCheck the default debug keystore location. my options are c: \ Users \ aboy123 \. Android \ Debug. keystore. 2. Run the following command in cmd: There are two for

Recently in a project, always reported the key error, map API reference, exactly according to the official document, how can it be wrong? ....... After many attempts, I found that each new key created by Eclipse will dynamically print a security code in the console, which is not the one that is displayed somewhere in eclipse (the official Baidu document say

1. First get your debug KeyStore location: Open the eclipse--->windows--->preferences--->android--->build View the default debug KeyStore location, for example: C:\Documents and Settings\ (name of your computer) \.android\debug.keystore Copy this file to the C disk or other letter (the simplest way to copy directly to the Java Bin directory) 2. Keytool is a Java-provided command to use this file to locate in the Java Bin directory: For example My computer This directory is: C:\Program files\java

Uiviewcontrollertransitioncoordinator protocol. (3) The new API mainly provides 2 ways of VC switching:A. Non-interactive switching, that is, the definition of a VC from one to another VC animation effect, when switching to automatically play,B. Interactive switch, this way also need to define the animation effect, but the animation effect will be based on following interactive gestures to switch the VC and play the animation effect. IOS7 provides a

After configuring the development environment (including Java environment variables) ----- 1. Find your Debug. keystore file in the eclipse tool, Choose windows --> preference --> Android --> build, The default debug keystore value is the path of DEBUG. keystore. ----- 2. Obtain the MD5 value of DEBUG. keystore. First, run the CMD command line to enter the path where the debug. keystore file is located, Run the following command: Keytool-list-alias androiddebugkey-keystore "C: \ Documen

1. First locate the debug keystore location: 2. In "cmd", type the following command: Keytool-list-alias androiddebugkey-keystore "C: \ Users \ itrue \.
