On the mobile phone, the offline map package is usually placed on the SD card and then read through the file. For the sake of simplicity, put offline in the Resource Directory of the example and compile it with the application. In actual applications, store these map packages separately. The Guide bee map development kit supports reading multiple map packages at the same time. This is done through the MapTiledZone class and MapTileStreamReader class.

Here the use of encryption and decryption using the Base64 transcoding method, ECB mode, pkcs5padding fill, password must be 16 bits, otherwise it will error!Mode: The ECB of Java corresponds to C # System.Security.Cryptography.CipherMode.ECBFill method: Java pkcs5padding corresponds to C#SYSTEM.SECURITY.CRYPTOGRAPHY.PADDINGMODE.PKCS7Java and C # version of the encryption and decryption is interoperability,

This example describes the AES encryption method in Java. Share to everyone for your reference. Specifically as follows: Java code: keygenerator kg = keygenerator.getinstance ("AES"); Gets the key generator kg.init (256);// //des algorithm must be 56-bit //desede algorithm can be 112-bit or 168-bit //aes algorithm can be 128, 192, 256 bit Secretkey key = Kg

Use Notification in Android to implement the normal Notification bar (Notification Example 1), and implement the rest example in java.
