I am trying to create a tower defense like game. I have created a tiled isometric map with Tiled Map Editor and have saved it is the assets folder in android studio. I am currently using andengine to load the map in my activity.
My MainActivity.Java :
package com.example.neelpatel104.towerfinisher;
import org.andengine.engine.Engine;
import org.andengine.engine.LimitedFPSEngine;
import org.andengine.engine.camera.BoundCamera;
import org.andengine.engine.options.EngineOptions;
import org.andengine.engine.options.ScreenOrientation;
import org.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
import org.andengine.entity.scene.Scene;
import org.andengine.entity.util.FPSLogger;
import org.andengine.extension.tmx.TMXLayer;
import org.andengine.extension.tmx.TMXLoader;
import org.andengine.extension.tmx.TMXProperties;
import org.andengine.extension.tmx.TMXTile;
import org.andengine.extension.tmx.TMXTileProperty;
import org.andengine.extension.tmx.TMXTiledMap;
import org.andengine.extension.tmx.util.exception.TMXException;
import org.andengine.extension.tmx.util.exception.TMXLoadException;
import org.andengine.opengl.texture.TextureOptions;
import org.andengine.ui.activity.SimpleBaseGameActivity;
import org.andengine.util.debug.Debug;
public class MainActivity extends SimpleBaseGameActivity {
private TMXTiledMap mTMXTiledMap;
private TMXLayer tmxLayer;
private static final int CAMERA_WIDTH=550;
private static final int CAMERA_HEIGHT=300;
private BoundCamera mBoundChaseCamera;
protected int mCactusCount;
@Override
public Engine onCreateEngine(EngineOptions engineOptions){
return new LimitedFPSEngine(engineOptions,60);
}
@Override
public EngineOptions onCreateEngineOptions(){
this.mBoundChaseCamera = new BoundCamera(0,0,CAMERA_WIDTH,CAMERA_HEIGHT);return new EngineOptions(true,ScreenOrientation.LANDSCAPE_FIXED,new RatioResolutionPolicy(CAMERA_WIDTH,CAMERA_HEIGHT),this.mBoundChaseCamera);
}
@Override
protected void onCreateResources() {
final TMXLoader tmxLoader = new TMXLoader(getAssets(),getTextureManager(),TextureOptions.NEAREST,mEngine.getVertexBufferObjectManager());
try {
this.mTMXTiledMap = tmxLoader.loadFromAsset("map/levelone.tmx");
} catch (final TMXLoadException e){
Debug.e(e);
}
}
@Override
protected Scene onCreateScene() {
this.mEngine.registerUpdateHandler(new FPSLogger());
final Scene scene = new Scene();
this.tmxLayer = this.mTMXTiledMap.getTMXLayers().get(0);
scene.setChildrenVisible(false);
scene.setBackgroundEnabled(false);
scene.attachChild(this.tmxLayer);
return scene;
}
}
The line below is giving me an error :
final TMXLoader tmxLoader = new TMXLoader(getAssets(),getTextureManager(),TextureOptions.NEAREST,mEngine.getVertexBufferObjectManager());
Here is my full Stack Trace :

I do not understand what the problem is. This error is present everytime I try to debug the program. I even tried to reinstall andengine and the TMXTiledMAP Extension, but the error is always there. I would like it if someone would take a look at it.
The build failed because some classes and methods are deprecated in latest versions. You may try to decrease compileSdkVersion for your andengine build.gradle file. Also you can fix most of these errors by simple changes:
To fix package org.apache.http does not exist error: add useLibrary 'org.apache.http.legacy' to andengine build.gradle file:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
}
}
apply plugin: 'com.android.library'
android {
compileSdkVersion 23
//buildToolsVersion '26'
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
}
useLibrary 'org.apache.http.legacy' //for support 23+ sdk
}
...
Class AvoidXfermode was deprecated, so set compileSdkVersion 23 as in code above. I will be appreciated if someone describe how to fix AvoidXfermode other way, without decreasing compileSdkVersion.
