Fixed bug 4268 - Android_JNI_OpenAudioDevice function has error

alittle

1.param set error

param:audioBuffer16Bit need change to captureBuffer16Bit

     6 #
     7 #   AX_CHECK_COMPILER_FLAGS(FLAGS, [ACTION-SUCCESS], [ACTION-FAILURE])
     8 #
     9 # DESCRIPTION
    10 #
    11 #   Check whether the given compiler FLAGS work with the current language's
    12 #   compiler, or whether they give an error. (Warnings, however, are
    13 #   ignored.)
    14 #
    15 #   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
    16 #   success/failure.
