I am using the plivo api, but when i open an activity, i get that error above, i know its coming from my endpoint instantiation, i.e i cannot do this
Endpoint endpoint = Endpoint.newInstance(true, this);
but i do not know what to do instead and i do not know what is causing the error

Plivo Sales Engineer here.
What's the processor architecture of the android phone that you're testing on? This error occurs when the libpjplivo.so file is incompatible with the processor architecture.
Please raise a ticket our support portal and we can help you debug this.

if you want to use only map service then only compile dependency of map:
compile 'com.google.android.gms:play-services-maps:10.0.0'
do not compile the complete play service dependency:
compile 'com.google.android.gms:play-services:10.0.1'
It will solve your problem.

To see code of the activity you can checkout this gist https://gist.github.com/darthvish/873dc292c841e5c86312

As you are using some deprecated features, so it may not supported for some API levels. For this you can check the api level as well as version before using the deprecated features using if condition. For example :
if(Build.VERSION.RELEASE.equals("4.4.4")) {
//Do somthing
}

So, thoughts?

I was also trying to implement it and got the same error .After lot of effort I was able to run it but received the similar error as you have received .
I resolved the issue by
1:Close and start your eclipse .
2: copying the v4 jar of main project in all the library projects and deleting the existing ones .
The error comes due to mismatch of supportv4jar. Make all the supportv4jar of same version
3:after that Delete the gen and bin folder and clean the project and run .
