where do i put my file ndk

I am struggling with this problem. I do not know where to put my file so that it can be visible when installing the apk

char s1[10];
        FILE *infile, *fopen();
        infile = fopen("/data/data/com.example.hellojni/files/datain.txt","r");

        if (NULL == infile)
        {

            return (*env)->NewStringUTF(env, "***can't find the file");
        }
        fgets(s1,9,infile);
        return (*env)->NewStringUTF(env,s1 );

I have no idea where to put my datain.txt. I put it in the bin folder but it isn't working. I keep saying can't find the file. The path is correct because I print it out on my screen.

Help pls,

Thanks. enter image description here

The most reliable approach I know about is:

First, in your Java code, store the file from your assets to some directory of the application, then pass the path of the file to the native function.
