Android拍照获得图片URI为空的处理方法

public void takePhoto() {
destoryBimap();
String state = Environment.getExternalStorageState();
if (state.equals(Environment.MEDIA_MOUNTED)) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
//这个是指定的uri地址，所以注释掉　如果指定了目标uri，data就没有数据，如果没有指定uri，则data就返回有数据
//            intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
startActivityForResult(intent, PHOTO_WITH_CAMERA);
} else {
Toast.makeText(getActivity(), "没有SD卡", Toast.LENGTH_LONG).show();
}
}

Bundle bundle =data.getExtras();
//获取相机返回的数据，并转换为Bitmap图片格式
aphoto = (Bitmap)bundle.get("data");
if (data.getData()!=null){
imageUri =data.getData();
}else {
imageUri = Uri.parse(MediaStore.Images.Media.insertImage(getActivity().getContentResolver(), aphoto, null,null));
}
//                    裁剪照片的方法
copePhoto(imageUri);
