Attempt To Invoke Virtual Method 'android.content.context.getapplicationinfo()' On A Null Object Reference In Android Studio

I had the Attempt to invoke virtual method 'java.util.List com.example.demo.Database.Database.getName()' on a null object reference error in my application and I solved that error

Solution 1:

Try justify "context" in your Database.java file using context = this; like this:

private static final String DB_NAME = "pharmacyDemo.db";
private static final int DB_VER = 1;

public Database(Context context) {
super(context, DB_NAME, null, DB_VER);
context = this;
}
