Android 为什么拍照后相机的意图没有恢复

我正在尝试编写一个函数，允许用户选择打开相机，然后当用户拍摄一张照片时，它返回，获取缩放的照片并在imageView上设置位图。问题是，在我拍了一张照片后，市场上的默认相机或其他相机应用程序都不会启动退货箱，如何修复？谢谢

拍照按钮：

takePic.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {
                File tempFile;
                try {
                    tempFile = File.createTempFile("my_app", ".jpg");
                    fileName = tempFile.getAbsolutePath();
                    Uri uri = Uri.fromFile(tempFile);
                    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
                    if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
                        startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
                    }
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }           
        });

意图结果后

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == REQUEST_GET_IMAGE_ALBUM && resultCode == RESULT_OK) {
            Uri selectedImage = data.getData();
            Intent shareIntent = new Intent(this, SharePicForm.class);
            shareIntent.putExtra("photo", Utility.getImagePath(selectedImage,this));
            startActivity(shareIntent);
        } else if ( requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
            Log.d("test1","return");
            Intent shareIntent = new Intent(this, SharePicForm.class);
            shareIntent.putExtra("photo", data.getStringExtra(MediaStore.EXTRA_OUTPUT));
            startActivity(shareIntent);
        }

    }

那么到底发生了什么，应用程序在返回时崩溃了吗？你有什么在Log Cat中显示的吗？没有崩溃什么都没有发生
