Plugin Development for Android 2.3

I am new to Android and using Android 2.3 . There is sample Browser plugin in the source code I am trying to build it but unable to do so.

To compile plugin [ In README.txt ]

1. run "make SampleBrowserPlugin" (compiles libsampleplugin.so and builds the apk)

2. the previous com开发者_StackOverflow社区mand produces an apk file so record its location.

   Using the above steps I am unable to build it.

   I have tried the following things :-
   
   I thought to build the code in JNI folder first so as to get the plugin ".so" so that after getting the ".so" would build the project apk using the eclipse .
   I tried building the code in the JNI folder using NDK build.The code was not geting build it was giving "undefined reference to JNIRegisterNativeMethod in JNIHelp.h "

   Can anyone tell me how to build the Sample plugin and install it on Emulator.

You need to "make SampleBrowserPlugin" from the root of your source installation (on a Linux machine). That is, the same directory that contains "bionic", "build", "dalvik", etc. as child directories.
