【问题描述】:
Android Studio 2.3.3(最新)
Cocos2d-x 3.15.1(最新)
我在 Debug 上进行了测试。
这是我第一次使用 Cocos2d-x 游戏引擎,我使用 Cocos2d-x 开发了一个 Android 游戏,一切都很好,但是当我尝试显示成就时,它显示了一个 错误,如下所示:
java.lang.NullPointerException
at sonar.systems.framework.SonarFrameworkFunctions.showAchievements(SonarFrameworkFunctions.java:432)
at org.cocos2dx.lib.Cocos2dxRenderer.nativeTouchesEnd(Native Method)
at org.cocos2dx.lib.Cocos2dxRenderer.handleActionUp(Cocos2dxRenderer.java:129)
at org.cocos2dx.lib.Cocos2dxGLSurfaceView$10.run(Cocos2dxGLSurfaceView.java:311)
at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1486)
at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1263)
点击显示成就时的我的代码:
SonarCocosHelper::GooglePlayServices::showAchievements();
当我想登录时:
java.lang.NullPointerException
at sonar.systems.framework.SonarFrameworkFunctions.isSignedIn(SonarFrameworkFunctions.java:277)
at org.cocos2dx.lib.Cocos2dxRenderer.nativeRender(Native Method)

at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1557)
at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1263)
我的登录代码:
if(!SonarCocosHelper::GooglePlayServices::isSignedIn())
SonarCocosHelper::GooglePlayServices::signIn();
我的清单文件:
