This leads to hardcoding the extra's name in Fragments that get the extra passed by an Activity.\n## What should happen\n\nGenerate a public class constant that holds the extra's name. This constant can be used in the generated activity instead of hardcoding and in fragments that get the extras passed.\n## Code Examples\n### Base File\n\n``` java\n@EActivity\npublic class NewPostActivity extends SherlockFragmentActivity {\n    @Extra\n    String photoUri;\n}\n```\n### Generated\n\n``` java\n private void injectExtras_() {\n        Intent intent_ = getIntent();\n        Bundle extras_ = intent_.getExtras();\n        if (extras_!= null) {\n            if (extras_.containsKey(\"photoUri\")) {\n                try {\n                    photoUri = cast_(extras_.get(\"photoUri\"));\n                } catch (ClassCastException e) {\n                    Log.e(\"NewPostActivity_\", \"Could not cast extra to expected type, the field is left to its default value\", e);\n                }\n            }\n        }\n    }\n\npublic NewPostActivity_.IntentBuilder_ photoUri(String photoUri) {\n            intent_.putExtra(\"photoUri\", photoUri);\n            return this;\n        }\n```\n### How it should be\n\n``` java\npublic static String photoUriExtra = \"photoUri\";\n\n private void injectExtras_() {\n        Intent intent_ = getIntent();\n        Bundle extras_ = intent_.getExtras();\n        if (extras_!= null) {\n            if (extras_.containsKey(photoUriExtra)) {\n                try {\n                    photoUri = cast_(extras_.get(photoUriExtra));\n                } catch (ClassCastException e) {\n                    Log.e(\"NewPostActivity_\", \"Could not cast extra to expected type, the field is left to its default value\", e);\n                }\n            }\n        }\n    }\n\npublic NewPostActivity_.IntentBuilder_ photoUri(String photoUri) {\n            intent_.putExtra(photoUriExtra, photoUri);\n            return this;\n        }\n```\n### in a fragment\n\n``` java\n// before solving this issue\n// if extra's name changes this variable can be easily forgotten\nfinal String photoUriExtra = \"photoUri\"; \n\n// after change\nfinal String photoUriExtra = NewPostActivity_.photoUriExtra;\n```\n","author":{"url":"https://github.com/ironjan","@type":"Person","name":"ironjan"},"datePublished":"2012-12-26T19:28:47.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/441/androidannotations/issues/441"}
