推荐答案

如果您的应用安装在 sdcard 上，请尝试以下代码:

If you app is insalled on sdcard try this code :

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);
}
