Fixed bug 4268 - Android_JNI_OpenAudioDevice function has error 

alittle

where iscapture == 1

1.param set error

(*env)->CallStaticIntMethod(env, mAudioManagerClass, midCaptureOpen, sampleRate, audioBuffer16Bit, audioBufferStereo, desiredBufferFrames)

param:audioBuffer16Bit need change to captureBuffer16Bit

2.logic error

if (is16Bit) {
        // ALITTLE Modify the source code
        if (iscapture) {
            audioBufferFrames = (*env)->GetArrayLength(env, (jshortArray)captureBuffer);
        } else {
            audioBufferPinned = (*env)->GetShortArrayElements(env, (jshortArray)audioBuffer, &isCopy);
            audioBufferFrames = (*env)->GetArrayLength(env, (jshortArray)audioBuffer);
        }
        // if (!iscapture) {
        //     audioBufferPinned = (*env)->GetShortArrayElements(env, (jshortArray)audioBuffer, &isCopy);
        // }
        // audioBufferFrames = (*env)->GetArrayLength(env, (jshortArray)audioBuffer);
    } else {
        // ALITTLE Modify the source code
        if (iscapture) {
            audioBufferFrames = (*env)->GetArrayLength(env, (jbyteArray)captureBuffer);
        } else {
            audioBufferPinned = (*env)->GetByteArrayElements(env, (jbyteArray)audioBuffer, &isCopy);
            audioBufferFrames = (*env)->GetArrayLength(env, (jbyteArray)audioBuffer);
        }
        // if (!iscapture) {
        //     audioBufferPinned = (*env)->GetByteArrayElements(env, (jbyteArray)audioBuffer, &isCopy);
        // }
        // audioBufferFrames = (*env)->GetArrayLength(env, (jbyteArray)audioBuffer);
    }
