Explain Exception handling in JNI.

There are two ways to handle an exception in native code:

-The native method can choose to return immediately, causing the exception to be thrown in the Java code that initiated the native method call.

-The native code can clear the exception by calling ExceptionClear (), and then execute its own exception-handling code. After an exception has been raised, the native code must first clear the exception before making other JNI calls. When there is a pending exception, the only JNI functions that are safe to call are ExceptionOccurred (),ExceptionDescribe (), and ExceptionClear (). The ExceptionDescribe () function prints a debugging message about the pending exception.

Bluetooth Data Transfer Example

Image
The following example uses the Android Bluetooth APIs to construct a simple peer-to-peer messaging system that works between two paired Bluetooth devices. Unfortunately the Android emulator can’t currently be used to test Bluetooth functionality. In order to test this application you will need to have two physical devices. 1. Start by creating a new BluetoothTexting project featuring a BluetoothTexting Activity. Modify the manifest to include BLUETOOTH and BLUETOOTH_ADMIN permissions. <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.paad.chapter13_bluetoothtexting" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".BluetoothTexting" android:label="@string/app_name"> <in
