退出主Activity崩溃：尝试移除未添加的OnFrameMetricsAvailableListener

问题背景 #

你遇到的情况很明确：

• 进入其他Activity后退出主Activity时，应用必然崩溃；但直接启动主界面后立即退出则完全正常
• 崩溃触发在主Activity的super.onStop();代码行，错误提示为：attempt to remove OnFrameMetricsAvailableListener that was never added
• 最后一次修改仅改动了根目录build.gradle的classpath，改为com.android.tools.build:gradle:3.1.2和com.google.gms:google-services:3.3.1，项目中完全没有使用过FrameMetrics相关对象

@Override 
public void onStop() { 
    super.onStop(); 
    StateManager mgr = new StateManager(this); 
    if (mMap != null) { 
        mgr.saveMapState(mMap); 
    } 
}

问题根源 #

从崩溃栈可以定位到，问题出在Firebase Performance的内部逻辑中：com.google.android.gms.internal.firebase-perf.zzd.onActivityStopped。它尝试移除一个从未被添加的FrameMetrics监听器，这是Firebase Performance与你当前使用的Gradle插件版本、Support库版本不兼容导致的已知bug。

可行的解决办法 #

1. 匹配Google Services与Firebase Performance版本
   确保google-services和firebase-perf的版本兼容。如果使用google-services:3.3.1，可以尝试将Firebase Performance依赖升级到16.2.0或更高版本（在app级build.gradle中）：

   implementation 'com.google.firebase:firebase-perf:16.2.0'
   

2. 降级Google Services版本
   把google-services改回之前能正常运行的版本，比如：

   classpath 'com.google.gms:google-services:3.2.1'
   

3. 暂时禁用Firebase Performance
   如果不需要性能监控功能，可以直接在AndroidManifest.xml中关闭它：

   <meta-data android:name="firebase_performance_collection_enabled" android:value="false" />
   

   或者移除app级build.gradle中的Firebase Performance依赖。

4. 升级Gradle插件到更稳定版本
   尝试将Gradle插件升级到3.2.1或更高稳定版，同时搭配对应的google-services版本（比如google-services:4.2.0），兼容性会更好：

   classpath 'com.android.tools.build:gradle:3.2.1'
   classpath 'com.google.gms:google-services:4.2.0'
   

最后记得执行Clean Project再Rebuild Project，清理缓存避免残留问题。
