添加我的Mapbox实现后，我开始收到此错误。更确切地说，我的build.gradle依赖项中的这些行会产生错误：

compile('com.mapbox.mapboxsdk:mapbox-android-sdk:5.2.0@aar') {
    transitive = true
}

一旦我按下启动游戏的按钮，应用程序就会崩溃。按下按钮后，此代码运行：

Intent intent = new Intent(getActivity(), PlatformerLauncher.class);
getActivity().startActivity(intent);

而这反过来运行这个类：

public class PlatformerLauncher extends AndroidApplication {

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

    AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
    initialize(new GamePlatformer(), config);
   }
}

GamePlatformer的内容：

public class GamePlatformer extends Game{
public SpriteBatch batcher;
@Override
public void create() {
    Gdx.input.setCatchBackKey(true);
    batcher = new SpriteBatch();
    //load assets
    Assets.load();

    //draw game
    setScreen(new PlatformerGameScreen(this));
}

@Override
public void render()
{
    super.render();
}
}

最后是完整的build.gradle：

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.mksolutions.platformerap"

    }

            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        main {
            jniLibs.srcDir 'libs'
        }
    }
}
configurations { natives }
dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile('com.mapbox.mapboxsdk:mapbox-android-sdk:5.2.0@aar') {
        transitive = true
    }

    compile project(':common')
    compile "com.badlogicgames.gdx:gdx-backend-android:$gdxVersion"
    natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-x86"

    compile 'com.google.android.gms:play-services-location:11.0.4'
    testCompile 'junit:junit:4.12'
}

task copyAndroidNatives() {
    file("libs/armeabi/").mkdirs();
    file("libs/armeabi-v7a/").mkdirs();
    file("libs/x86/").mkdirs();
    configurations.natives.files.each { jar ->
        def outputDir = null
        if (jar.name.endsWith("natives-armeabi-v7a.jar")) outputDir = file("libs/armeabi-v7a")
        if (jar.name.endsWith("natives-armeabi.jar")) outputDir = file("libs/armeabi")
        if (jar.name.endsWith("natives-x86.jar")) outputDir = file("libs/x86")
        if (outputDir != null) {
            copy {
                from zipTree(jar)
                into outputDir
                include "*.so"
            }
        }
    }
}

有人对我做错了什么有建议吗？

答案

发现android设备试图访问不存在的库。

解决方案：

将此添加到build.gradle中的defaultConfig：

    defaultConfig {
        ...
        ndk {
            abiFilters "armeabi-v7a", "x86", "armeabi"
        }
    }

并在gradle.properties中添加此行：

android.useDeprecatedNdk=true

重新同步gradle。
