android 调用系统相册裁剪无效

 Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
      photoPickerIntent.setType("image/*");
      startActivityForResult(photoPickerIntent, CHOOSE_PICTURE);


case CHOOSE_PICTURE:
 if (resultCode == RESULT_OK && data != null) {
 Uri uri = data.getData();
 Intent intent = FileTools.crop(uri);
 startActivityForResult(intent, COVER_REQUEST_CUT);
 }
 break;
 case COVER_REQUEST_CUT:
 if (resultCode == RESULT_OK && data != null) {
 try {
 img = data.getParcelableExtra("data");
 // img = ImageUtil.pressImage1_4(img);
 String path = "";
 File file = FileTools.saveBitmapToFile(img);
 if (file != null) {
 //UIHelper.showToast(context, file.getAbsolutePath());
 path = file.getAbsolutePath(); // 图片文件路径
 }
 ImageUtil.registerImage(context, path);
 JsCall jsCall = (JsCall) appApplication
 .getAndDeleteData("localfileOpen");
 pathCallBack(jsCall, path);
 } catch (Exception e) {
 e.printStackTrace();
 }
 }
 break;

}

用这种试试
