Since AIDL is not for passing large data, a blob can be passed to APG by a Uri. This Uri is opened as a file by APG and read/written to. Note the file is overwritten by APG, so make sure it is a copy if you want to keep the original. With the ApgServiceBlobProvider, Apg has an own ContentProvider that can be used like mentioned above. For now the data is stored in the dir where APG stores other files and NOT DELETED after en/decryption. This is tbd. It can only be accessed by an application with the permission "org.thialfihar.android.apg.permission.STORE_BLOBS". ApgCon has been updated accordingly and can handle blobs with `setBlob` and `getBlobResult`. That is a really easy way to en/decrypt large data. Note that encrypting by blob should only be used for large files (1MB+). On all other cases, the data should be passed as as String through the AIDl-Interface, so no temporary file must be created. See ApgCon for a complete example of how to connect to the AIDL and use it. Or use it in your own project!
