Android 内存检测工具 leakcanary 自定义栈管理Activity 报错

[harveyhaha]

最近看了android的内存检测工具不错 装上试了下 开始就 我的自定义栈管理类报错 ScreenManger 报错 我只是在baseactivity 里 oncreate 和 ondestory 调用了 pushActivity 和 popActivity

public void pushActivity(Activity activity) {
ScreenManager.getInstance().pushActivity(activity);
}
public void popActivity(Activity activity) {
ScreenManager.getInstance().popActivity(activity);
}
