Question

我正在尝试拖动图片并将其添加到pdf文件中，并使用qoppa库保存此PDF文件，我的功能正常运行但保存我的应用程序后崩溃了。我的代码是

    StandardFontTF.mAssetMgr = getAssets();

    String val = "/sdcard/TEST.pdf";
    Log.e("pdffilename",""+val);

    mStampImage = BitmapFactory.decodeFile("/sdcard/122.jpg");
    //mStampImage = BitmapFactory.decodeFile("/mnt/sdcard/imagex/"
            //+ signatureName);

    mStampButton = new Button(this);
    Log.e("sing","sing"+mStampButton);
    mSaveDocButton = new Button(this);
    mStampButton.setText("Sign");
    mSaveDocButton.setText("Confirm");
    mStampButton.setHeight(40);
    mStampButton.setOnClickListener(this);
    mSaveDocButton.setOnClickListener(this);

    mNotesView = new QPDFNotesView(this);
    Log.e("sing","sing"+mNotesView);
    mNotesView.setActivity(this);

    // ///////////////
    // mNotesView.loadDocument("/sdcard/Attachment.pdf");
    mNotesView.loadDocument(val);
    // /////////////////////
    // removing unwanted buttons
