Hi,
I am trying to connect to mongodb from android directly, but getting error
and app stops.
mongoClient = new MongoClient(uri);
Getting null from: Caused by: java.lang.NullPointerException: Attempt to
invoke virtual method 'java.security.CodeSource
java.security.ProtectionDomain.getCodeSource()' on a null object reference
Because java.security.ProtectionDomain is in legacy and is being picked from
*implementation 'com.android.support:appcompat-v7:26.1.0'*
So I want to pick *java.security* package from *JDK-1.8* and not from
*com.android.support:appcompat-v7:26.1.0.*
How can I do that.
Below is error logs from Android Studio.
