                    for (File temp : f.listFiles())
                    {
                        if (temp.getName().equals("temp.jpg"))

推荐答案

Excepstion说你的文件不存在于指定的路径上

Excepstion says that your file donot exists on the specified path

检查文件路径

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data");

        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        photo.compress(Bitmap.CompressFormat.JPEG, 40, bytes);

        //you can create a new file name "test.jpg" in sdcard folder.
        File f = new File(Environment.getExternalStorageDirectory()
                                + File.separator + "test.jpg");
        try {

            f.createNewFile();
            //write the bytes in file
            FileOutputStream fo = new FileOutputStream(f);
            fo.write(bytes.toByteArray());
            // remember close de FileOutput
            fo.close();

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        if (f.exists()) {

            Toast.makeText(this, "Image Found : "+f.getAbsolutePath().toString(), Toast.LENGTH_SHORT).show();
             new UpdateProfilePicApi().execute(f.getAbsolutePath().toString());
        }else{
              Toast.makeText(this, "Image Not Found", Toast.LENGTH_SHORT).show();
        }


    }
}

和你的意图

Intent cameraIntent = new Intent(
                    android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_REQUEST);
