What is the difference between the raw folder and the asset folder in Android?

* Similarities between Res/raw and assets:

1. Files in the two directories will be stored in the APK package intact after packaging, and will not be compiled into binary.

* Differences between Res/raw and assets:

1. files in RES/RAW will be mapped to R. in the Java file, the resource ID is R. id. filename; files in the assets folder will not be mapped to R. in Java, the assetmanager class is required for access.

2. Res/Raw cannot have a directory structure, while assets can have a directory structure, that is, folders can be created under the Assets Directory.

* Read File resources:

1. Read the file resources under Res/raw and get the input stream for write operations in the following ways

• Inputstream
  Is = getresources (). openrawresource (R. Id. filename );
  

2. Read the file resources under assets and get the input stream for write operations in the following ways

• Assetmanager
  AM = NULL;
  
• AM
  = Getassets ();

• Inputstream
  Is = aM. Open ("FILENAME ");
