Android java.lang.ClassNotFoundException

Question

我知道在SO上有很多问题,但遗憾的是没有一个答案能解决我的问题.

我有3个用于测试+模拟器的Android设备,我的应用程序在所有这些设备上工作正常,但是当我发布应用程序时,我收到此错误(仅在少数设备上,而不是全部):

java.lang.RuntimeException: Unable to start activity ComponentInfo{<package>/<package>.<ProjectName>Activity}: android.view.InflateException: Binary XML file line #10: Error inflating class <package>.MainSurfaceView

该类扩展了类GLSurfaceView并且有3个构造函数(GLSurfaceView仅支持2个,但我在SO上读到缺少的第三个可能导致问题 - 它没有).

类(仅构造函数):

public class MainSurfaceView extends GLSurfaceView {

    public MainSurfaceView(Context context) {
        super(context);
    }

    public MainSurfaceView(Context context, AttributeSet attrs){
        super(context, attrs);
    }

    public MainSurfaceView(Context context, AttributeSet attrs, int defStyle){
        super(context, attrs);
    }
}

添加构造函数

public MainSurfaceView(Context context, AttributeSet attrs, int defStyle){
    super(context, attrs);
}

没有解决问题.

我的清单文件:

谢谢你的帮助.如果有人能告诉我如何重新创建错误,那将会非常有帮助.

如果您已更新到ADTv17或更高版本,旧的ProGuard文件将对您执行此操作.创建一个新的空项目,并查看project.properties和proguard-properties并相应地修改当前项目.
