In Java, the java. lang. NullPointerException is thrown when a reference variable is accessed (or de-referenced) and is not pointing to any object. This error can be resolved by using a try-catch block or an if-else condition to check if a reference variable is null before dereferencing it.
How to fix the NullPointerException? To avoid NullPointerException we have to initialize the Textview component with the help of findviewbyid( ) method as shown below. The findViewbyId( ) takes the “id” value of the component as the parameter. This method helps locate the component present in the app.
java.lang.NullPointerException. Thrown when an application attempts to use null in a case where an object is required. These include: Calling the instance method of a null object. Accessing or modifying the field of a null object.
The java. lang. NullPointerException is a runtime exception in Java that occurs when a variable is accessed which is not pointing to any object and refers to nothing or null. Since the NullPointerException is a runtime exception, it doesn't need to be caught and handled explicitly in application code.
Issue #170849 gives the reasons for the above crash.
- This happens (at least) when no sdk is installed and no remote repos that contain platforms are available.
- Actually it happens whenever remote sites aren't available and the first run wizard is run.
Found a temporary solution from Issue #170850:
Add the following code to C:\Program Files\Android\Android Studio\bin\idea.properties
disable.android.first.run=true The issue has been fixed under Issue #170849.
