Gallery Intent在Android 4.0.3上不起作用

这是我从图库中获取图像的代码

intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, GALLERY_INTENT);

这是onActivityResult方法

这段代码在android 2.3.4版本上运行良好，但当我在4.0.3设备上测试这段代码时，它不工作，可能是什么问题？

我已经解决了这个问题

            Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
            ZootOutObject.objectUri = getImagePath();
            intent.putExtra(MediaStore.EXTRA_OUTPUT, ZootOutObject.objectUri);
            startActivityForResult(intent, CAMERA_INTENT);

如果requestcode==1&&resultCode==RESULT\u正常{

             String pathName=Environment.getExternalStorageDirectory()+"/folder_name/image_zootout.jpg";

             Intent intent = new Intent(getApplicationContext(),PhotoEditorActivity.class);
             intent.putExtra("IMAGE_PATH", pathName);
             intent.putExtra("OUTLET_ID", 0);
             intent.putExtra("OUTLET_NAME", "");
             startActivity(intent);

       }


private Uri getImagePath() {
    // If sd card is available
        if(android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED)){
            String path = Environment.getExternalStorageDirectory() .getAbsolutePath();
            filename = "image_zootout.jpg";
            path += "/folder_name";
            File file = new File(path);
            if (!file.isDirectory()) {
                file.mkdirs();
            }
            path += "/" + filename;
            File imageFile = new File(path);
            if (!imageFile.exists()) {
                try {
                    imageFile.createNewFile();
                } catch (IOException e) {
                    e.printStackTrace();
                    return null;
                }
            }
            return Uri.fromFile(imageFile);
        }else{ // If sd card is not available
            return null;
        }
    }

当你说：它不工作时，你的确切意思是什么？你能更具体地说明它做什么和不做什么吗？例如，是否引发了异常？或者它只是没有打开库？在你试图激发意图时，Logcat中是否有任何消息？方法中的imageFilePath为我提供了到imag的正确路径在4.0.3版本中，你有它的ans吗？如果有，请分享我也有同样的问题intent intent intent=new intent和roid.provider.MediaStore.ACTION\u IMAGE\u CAPTURE；ZootOutObject.objectUri=getImagePath；intent.putExtraMediaStore.EXTRA\u OUTPUT，ZootOutObject.objectstartactivityforresultentint，摄像机意图；
