웹뷰를 파일로 저장하려고 할때..

Question

public boolean onWebViewAllCapture(WebView mWebView, String mFilePath, String mScreenShotName) {
   Picture mPicture = mWebView.capturePicture();
   Bitmap mBitmap = Bitmap.createBitmap(mPicture.getWidth(), mPicture.getHeight(), Bitmap.Config.ARGB_8888);
   Canvas mCanvas = new Canvas(mBitmap);
   mPicture.draw(mCanvas);
   File mFolder = new File(mFilePath);
   if (!mFolder.exists()) {
      mFolder.mkdirs();
   }

   File mFile = new File(mFilePath + mScreenShotName);

   try {
      FileOutputStream mFileOutput = new FileOutputStream(mFile);
      mBitmap.compress(Bitmap.CompressFormat.PNG, 100, mFileOutput);
      mFileOutput.close();
   } catch (Exception var10) {
      var10.printStackTrace();
   }

   mWebView.setDrawingCacheEnabled(false);
   return mFile.exists();
}

 

 

 

안드로이드 버전을 14에서는 잘되는데 28로 올리니까 안됩니다..

 

어떤 방법이 있을까요...
