If you app is insalled on sdcard try this code :
如果您的应用程序安装在 sdcard 上，请尝试以下代码：
Bitmap bitMap = BitmapFactory.decodeResource(getResources(),R.id.img1);
File mFile1 = Environment.getExternalStorageDirectory();
String fileName ="img1.jpg";
File mFile2 = new File(mFile1,fileName);
try {
FileOutputStream outStream;
outStream = new FileOutputStream(mFile2);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
outStream.flush();
outStream.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String sdPath = mFile1.getAbsolutePath().toString()+"/"+fileName;
Log.i("hiya", "Your IMAGE ABSOLUTE PATH:-"+sdPath);
File temp=new File(sdPath);
if(!temp.exists()){
Log.e("file","no image file at location :"+sdPath);
}

或者
Uri otherPath = Uri.parse("android.resource://com.nikhil.material/drawable/image");

drawable resources are added to binary at run time therefore cannot be accessed by path. you can decode and use drawables instead.
drawable 资源在运行时被添加到二进制文件中，因此无法通过路径访问。您可以解码并使用可绘制对象。
If you need resources you can access at runtime by path, try using assets folder instead.
如果您需要可以在运行时通过路径访问的资源，请尝试使用 assets 文件夹。
Hope this is helpful
