Und der Code:

package com.example.cocol.timisoara2021; 

import android.os.Bundle; 
import android.support.v7.app.AppCompatActivity; 

import com.wikitude.architect.ArchitectStartupConfiguration; 
import com.wikitude.architect.ArchitectView; 

public class Main2Activity extends AppCompatActivity { 


    private ArchitectView architectView; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main2); 


     this.architectView = (ArchitectView) this.findViewById(R.id.architectView); 

     final ArchitectStartupConfiguration config = new ArchitectStartupConfiguration(); 
     config.setLicenseKey("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"); 
     this.architectView.onCreate(config); 

    } 


    protected void OnPostCreate(Bundle savedInstanceState) { 

     super.onPostCreate(savedInstanceState); 

     architectView.onPostCreate(); 

     try { 
      this.architectView.load("file:///android_asset/POI/index.html"); 
     }catch (Exception e) { 


     } 
    } 

    @Override 
    protected void onPause() { 

     super.onPause(); 
     architectView.onPause(); 
    } 

    @Override 
    protected void onResume() { 
     super.onResume(); 
     architectView.onResume(); 

    } 

    @Override 

    protected void onDestroy() { 

     super.onDestroy(); 
     architectView.onDestroy(); 
    } 




} 

Wie kann ich dieses Problem beheben?

Answer 1

Ihre onPostCreate-Methode hat einen Großbuchstaben "O". Aus diesem Grund gehe ich davon aus, dass es nie aufgerufen wird, was bedeutet, dass sich die ArchitectView beim Aufruf von architectView.onResume in einem ungültigen Zustand befindet.

Versuchen:

@Override 
protected void onPostCreate(Bundle savedInstanceState) { 
    super.onPostCreate(savedInstanceState); 

    architectView.onPostCreate(); 
    try { 
     this.architectView.load("file:///android_asset/POI/index.html"); 
    }catch (Exception e) { 
    } 
}
