That my friend is an array of bytes. In JNI, [B is used to describe an array ([) of bytes (B). An array of ints is [I etc. You can get a bit more information on field descriptors here:JNI Types and Data Structures (Table 3-2 should be what you are looking for).
If input value can be in numeric form other than integer , check by If string value is being passed , use Integer.parseInt(string_var). Please ensure error handling using try catch in case conversion fails.
problem is not in the code, but you don’t have added the driver to your project!!!

800×480 is the most common resolution on Android powered devices. Your aspect ratio would be: 5:3 (which is the same as 800:480 just put in its simplest form). All your graphics should be created on a composition with the size 800×480, not to have stretched graphics when you run your game. I would suggest you … Read more
Based on the conversation in the other answer, it was inferred that the JVM was a 64-bit process. This was confirmed using the pflags command in Solaris. Apparently the -d32 flag passed to the JVM was being ignored. This was due to the possibility of the JVM being a 64-bit one, which was incapable of operating in the 32-bit mode. … Read more
A Java class can only extend one parent class. Multiple inheritance (extends) is not allowed. Interfaces are not classes, however, and a class can implement more than one interface. The parent interfaces are declared in a comma-separated list, after the implements keyword. In conclusion, yes, it is possible to do:
Since String IS-A CharSequence, you can pass a String wherever you need a CharSequence, or assign a String to a CharSequence: If you want to convert a CharSequence to a String, just use the toString method that must be implemented by every concrete implementation of CharSequence.
I don’t know about Eclipse’s failures (god knows I’ve pulled enough hair out trying to fix issues my coworker gets using Eclipse), but could you manage with using the [home] character? It’s a kludge compared to \b for your purpose, but if the output you’re using doesn’t work with one control character, try another! 🙂
^^ PS : true = 1 and false = 0
