NullPointerException

Without looking or seeing you code I don’t know where your going wrong. I think you using an object and not initialised hence “null object reference”. so your trying to use something that don’t exist. Have you called a class without doing a Object = new Object();
or a static Class without calling the Object = object::create();
or you creating something in a function then its going out of scope when retuning from a function.
but something is definitely NULL. But cannot point to what is going on without looking at code.

#3

For the first one your libraries did not have this method “void android.content.pm.PackageManager$OnChecksumsReadyListener.onChecksumsReady(java.util.List)”
Maybe you are calling some method that only available in an older / newer version libraries.

#5

okay, thank you all for your response I am still evaluating this.
