I tried to run a command via Android terminal, but when I execute my command:
"svc data enable/disable" this error appears:
"Warning: l
The text relocations is a warning, not an error. It was only added to Android comparatively recently.
As it appears that the program in question (app_process) was one furnished with the system rather than compiled by you, there is nothing you can or need to do about it, unless you feel like rebuilding/replacing the system component in question.
Were you building your own program, your question could be marked as a duplicate of
mylib.so has text relocations. This is wasting memory and is a security risk. Please fix
However, that would only apply to software you were compiling yourself.
In this case, you will probably just have to ignore it, unless you are somehow (?) using app_process
to launch something with a custom native library that you did build, in which case you should update your NDK as explained in the other question.
Your permissions denied
is unrelated to the previous error message, and most likely a problem with the command you are trying to run (for example, you think you are root but you are not). If you want help with that, you are going to have to be more specific about the command you are running and the mechanism used to launch it.
