当我使用浏览器时,我想保存我访问过的网站的屏幕截图.因为有些页面将来会消失.所以我决定做一个后台服务,当我访问网站www.site.com时,会定期制作截图.谁可以给我任何提示,教程链接,示例,……?
附:我的手机扎根了. Android 2.1.并且不要说这是不可能的:)
更新:
屏幕截图为JPG格式或HTML,没有区别.这种方法更容易制作.
解决方法
Process sh = Runtime.getRuntime().exec("su",null,null); OutputStream os = sh.getOutputStream(); os.write(("/system/bin/screencap -p " + "/sdcard/img.png").getBytes("ASCII")); os.flush(); os.close(); sh.waitFor(); then read img.png as bitmap and convert it jpg as follows Bitmap screen = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory()+ File.separator +"img.png"); //my code for saving ByteArrayOutputStream bytes = new ByteArrayOutputStream(); screen.compress(Bitmap.CompressFormat.JPEG,15,bytes); //you can create a new file name "test.jpg" in sdcard folder. File f = new File(Environment.getExternalStorageDirectory()+ File.separator + "test.jpg"); f.createNewFile(); //write the bytes in file FileOutputStream fo = new FileOutputStream(f); fo.write(bytes.toByteArray()); // remember close de FileOutput fo.close();
