Paypal service does not start (account in the sandbox), I get below the error

I have an activity called sample activity. From this activity, I discovered the intention, it was the operation navigationlayout1, in which there was a PayPal service. Oncreate this service should be added as they (paypal) made in their example. I did not have this problem before when I did not use the multidex option.

I got an error such as "exit value 2", my gradle was unable to execute due to this error. I did some research to clear this error.

Finally, my previous error (output value 2) cleared. I was happy because now there is no mistake. But suddenly I got this error. Over the past 3 days, I am stuck in error. I do research all the time. This is the right time to ask here without spending me more time. Please help me.

you can add two gradle files with "com.paypal.sdk:paypal-android-sdk:2.14.2"

compile 'com.squareup.okhttp3:okhttp:3.3.1'
compile 'com.squareup.okio:okio:1.8.0'

Alternatively, you can download OkHttp.jar and Okio. jar , and put them under the libs folder.
