android 解决小米手机上选择照片路径为null情况

昨天测试帅哥说他手机选择图库崩溃了,这是一个上传头像的功能,相信很多应用都有这个功能,于是我就把手机拿过来打log看了下返回的路径 为null,在网上搜索了下解决方案,现在把解决方案记录下：

这是在onActivityResult方法中执行的,

if (data == null) {
                return;
            }
            uri = data.getData();
            uri = geturi(data);//解决方案
            String[] proj = { MediaStore.Images.Media.DATA };
            Cursor cursor = managedQuery(uri, proj, null, null, null);
            if(cursor!=null){
                int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                cursor.moveToFirst();
                String path = cursor.getString(column_index);// 图片在的路径
                Intent intent3 = new Intent(this, SYClipActivity.class);
                intent3.putExtra("path", path);
                startActivityForResult(intent3, IMAGE_COMPLETE);
            }

     public Uri geturi(android.content.Intent intent) {
            Uri uri = intent.getData();
            String type = intent.getType();
            if (uri.getScheme().equals("file") && (type.contains("image/"))) {
                String path = uri.getEncodedPath();
                if (path != null) {
                    path = Uri.decode(path);
                    ContentResolver cr = this.getContentResolver();
                    StringBuffer buff = new StringBuffer();
                    buff.append("(").append(Images.ImageColumns.DATA).append("=")
                            .append("'" + path + "'").append(")");
                    Cursor cur = cr.query(Images.Media.EXTERNAL_CONTENT_URI,
                            new String[] { Images.ImageColumns._ID },
                            buff.toString(), null, null);
                    int index = 0;
                    for (cur.moveToFirst(); !cur.isAfterLast(); cur.moveToNext()) {
                        index = cur.getColumnIndex(Images.ImageColumns._ID);
                        // set _id value
                        index = cur.getInt(index);
                    }
                    if (index == 0) {
                        // do nothing
                    } else {
                        Uri uri_temp = Uri
                                .parse("content://media/external/images/media/"
                                        + index);
                        if (uri_temp != null) {
                            uri = uri_temp;
                        }
                    }
                }
            }
            return uri;
        }

在此记录下,
