尺蠖誤差libGDX

我不是很熟悉Android的活動，以及如何，所有的作品;任何關於這個話題的指導都會很棒。我遇到了將廣告SDK與我的遊戲集成的問題。我將介紹幾個課程，以充分理解我的代碼。本質上，我試圖確定一個將StartApp sdk（廣告SDK）與我的libGDX遊戲集成的好方法。我得到了什麼似乎是由startAppAd.show（）造成的活套錯誤;和startAppAd.load（）;被稱爲。尺蠖誤差libGDX

這裏是堆棧跟蹤（提一個UI線程，並在不同的線程加載廣告）：

它似乎有事情做，試圖啓動活動中加載廣告。這裏是我的發射活動（以及由於libGDX唯一的活動只在運行了Android一個活動）：

package com.audiack.freetappgame; 

import Screens.FreeTappGame; 
import UtilityClasses.StartAppResolver; 
import android.os.Bundle; 
import android.os.Looper; 

import com.badlogic.gdx.backends.android.AndroidApplication; 
import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration; 
import com.badlogic.gdx.graphics.Texture; 
import com.searchboxsdk.android.StartAppSearch; 
import com.startapp.android.publish.StartAppAd; 

public class MainActivity extends AndroidApplication implements StartAppResolver{ 
    public StartAppAd startAppAd = new StartAppAd(this); 
    public StartAppSearch startAppSearch= new StartAppSearch(); 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration(); 

     StartAppAd.init(this, "101164873", "201640058"); 
     StartAppSearch.init(this, "101164873", "201640058"); 

     Texture.setEnforcePotImages(false); 
     cfg.useGL20 = true; 

     initialize(new FreeTappGame(this), cfg); 
     StartAppSearch.showSearchBox(this); 
    } 
    @Override 
    public boolean showAds() { 
     startAppAd.load(); 
     startAppAd.show(); 
     return true; 
    } 

    @Override 
    public boolean resume() { 
     startAppAd.onResume(); 
     return true; 
    } 
    @Override 
    public boolean backButton() { 

     return true; 
    } 
    @Override 
    public boolean pause() { 
     startAppAd.onPause(); 
     return true; 
    } 
}

正如你可以看到我有這個活動實現我創建了一個接口，然後我通過活動本身ApplicationListener，允許libGDX方法與活動交互。這是接口;基於關我小時的研究，這是對中libGDX廣告整合的最佳方式（但這些方法都是類似的廣告SDK的沒有的startApp直接）：

package UtilityClasses; 

public interface StartAppResolver { 
    public boolean showAds(); 
    public boolean resume(); 
    public boolean backButton(); 
    public boolean pause(); 
}

最後了ApplicationListener（在FreeTappGame類）：

package Screens; 


import UtilityClasses.Assets; 
import UtilityClasses.StartAppResolver; 

import com.badlogic.gdx.ApplicationListener; 
import com.badlogic.gdx.Game; 
import com.badlogic.gdx.Gdx; 

public class FreeTappGame extends Game implements ApplicationListener { 
    static float Width; 
    static float Height; 

    public StartAppResolver startAppResolver; 

    public SplashScreen splash_screen; 
    public MenuScreen menu_screen; 
    public GameScreen game_screen; 
    public HighscoreScreen highscore_screen; 
    public AboutScreen about_screen; 

    public FreeTappGame(StartAppResolver startAppResolver) { 
     this.startAppResolver = startAppResolver; 
    } 

    @Override 
    public void create() { 
     Width = Gdx.graphics.getWidth(); 
     Height = Gdx.graphics.getHeight(); 
     Assets.load(); 

     splash_screen = new SplashScreen(this); 
     menu_screen = new MenuScreen(this); 
     game_screen = new GameScreen(this); 
     highscore_screen = new HighscoreScreen(this); 
     about_screen = new AboutScreen(this); 

     setScreen(splash_screen); 
    } 
}

謝謝你這麼多的時間。

我想通了，我會盡快發佈解決方案。 –

你需要調用

Looper.prepare();

而且一定要在只有一個線程調用它一次。這個工作對我來說：

boolean looperprepare = false; 


public void yourmethod(){ 
    if (!looperprepare) { 
     Looper.prepare(); 
     looperprepare = true; 
    } 
    .... 
}

當我這樣做時，它說我只能創建一個活套。我發現了一個工作解決方案。當我被允許時我會發布它。 –

我會刪除此線程，因爲有一個類似的問題在這裏：WebView Methods is not called in android 但目前還沒有計算器上許多的startApp解決方案，我認爲這個問題將是有益的人誰正在嘗試整合startapp。我換成

@Override 
    public boolean showAds() { 
     startAppAd.load(); 
     startAppAd.show(); 
     return true; 
    }

與

@Override 
public boolean showAds() { 
    this.runOnUiThread(new Runnable() { 
     @Override 
     public void run() { 
     startAppAd.show(); 

     } 
    }); 
    return true; 
}

和我的初始化方法後，就把startAppAd.load（）：

initialize(new FreeTappGame(this), cfg); 
startAppAd.load();

該訣竅我;我希望這可以幫助別人。
