每次我退出主要 Activity 时，应用程序都会崩溃，但前提是我在此之前进入另一个 Activity 。 这意味着，如果我只是进入第一个屏幕并在进入另一个 Activity 之前退出它，应用程序就不会崩溃。

我在主要 Activity 中的 “super.onStop();” 行发生崩溃，原因是错误提示:“attempt to remove OnFrameMetricsAvailableListener that was从未添加”。

上次代码运行良好，我最后更改的是 build.gradle 和一些类路径:classpath 'com.android.tools.build:gradle:3.1.2' 和类路径“com.google.gms: google-services: 3.3.1”。没有别的..

(此外，即使我没有调用 onStop() 方法，应用程序也会崩溃。我想补充一点，我根本没有在我的项目中使用 FrameMetrics 对象!!)

非常感谢任何能提供帮助的人!

@Override
public void onStop() {
    super.onStop();

    StateManager mgr = new StateManager(this);
    if (mMap != null) {
        mgr.saveMapState(mMap);
    }
}

崩溃

最佳答案

从 AndroidManifest.xml 中删除 android:hardwareAccelerated="false" 帮助了我

关于java - 尝试删除从未添加的 OnFrameMetricsAvailableListener，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50281141/
