Et le 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(); 
    } 




} 

Comment puis-je résoudre ce problème?

Answer 1

Votre méthode onPostCreate a un "O" majuscule. Pour cette raison, je suppose qu'il n'est jamais appelé, ce qui signifie que ArchitectView est dans un état invalide lorsque vous appelez architectView.onResume.

Essayez:

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

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