An android binder library for rust

binder_alloc: 270: binder_alloc_buf size 131152 failed, no address space

Running the client to send messages to the server multiple times results in a memory shortage error. I have checked the current code and found no usage of BC_FREE_BUFFER. Could there be a problem with this part?

Security problem on Android 9

When I run the example program on Android 9, when I use Rust to register the Binder service and obtain the Binder interface, an error Parcel object will be returned, prompting EX_SECURITY. I'm running as root. I don't know if there is any way to solve this problem?

examples panic Err` value: Error { kind: UnexpectedEof, message: "failed to fill whole buffer" }

when i run examples , it will panic like this
"
