使用alaSql从blob中读取xls

Question

我开始使用alaSQL并且看起来非常有前途，这个例子在阅读XLS文件时似乎很简单，但是我无法让它工作。

private Runnable mRunnable = new Runnable() {
    @Override
    public void run() {
        isImage = false;
        startRecording();
    }
};


mCaptureButton.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    // Start recording after 1 sec
                    isImage = true;
                    mHandler = new Handler();
                    mHandler.postDelayed(mRunnable, 1000);
                    break;
                case MotionEvent.ACTION_UP:
                    // If video recording was started after 1 sec delay then stop recording
                    // otherwise capture image
                    if(isImage) {
                        // Cancel handler for video recording
                        mHandler.removeCallbacks(mRunnable);
                        // Capture image
                        mCamera.takePicture(null, null, mPicture);
                    } else {
                        // Stop video recording
                        stopRecording();

                    }
                    break;
            }
            return true;
        }
    });

它抛出的错误无法从未定义的属性中读取。任何领导或帮助将不胜感激
