Java.lang.NullPointerException at getapplicationContext() while initiating adapter

android, java, nullpointerexception

Solution

Don't initialize it before `OnCreate()`, you can't get Context with there, do it in `onCreate()`.

private globalAdapter adpt;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.loading);
    adpt  = ((globalAdapter)getApplicationContext());
    ...
}

Problem

While running the project on Android emulator,I face the exception as java.lang.NullPointerException at getApplicationContext.Please help me to resolve this issue.
