项目场景：

车载项目，ATC8257-Android9.0系统平台，福田汽车P3系列项目

项目使用高德公版地图前提是无法获得任何高德定制服务，每次刷完机去切换语言系统会弹出"高德地图已停止运行"弹窗，严重影响用户使用体验

问题描述

项目使用高德公版地图前提是无法获得任何高德定制服务，每次刷完机去切换语言系统会弹出"高德地图已停止运行"，但是刷完机先把高德打开一次再去切换语言就不会有这个问题，报错内容如下：

原因分析：

验证过刷完机先把高德打开一次再去切换语言就不会有这个问题，结合上面报错内容，分析是刷完机后高德接收语言切换的广播代码没有主动完成初始化，当系统切换语言的广播发送后高德无法处理导致弹出“高德地图已停止运行”弹窗。

解决方案：

授人以鱼不如授人以渔

1.既然出现这种系统弹窗，我思索的是能不能在系统里面把高德包名过滤掉，弹窗的地方先获取包名是高德包名就return，有了这种思路后第一步还是借助万能网络，很自然就搜到这篇CSDN博客
屏蔽弹出停止运行对话框
修改位置：frameworks\base\services\core\java\com\android\server\am\AppErrors.java
这篇博客给出了修改方法，但是并没有说在具体哪个代码块里面改，我们通过里面的mService.killAppAtUsersRequest(proc, null)这行代码去AppErrors.java里面搜索，发现handleShowAnrUi方法里面有一处，按照博客的方法这样加

    void handleShowAnrUi(Message msg) {Slog.w(TAG, "------------------handleShowAnrUi");Dialog dialogToShow = null;synchronized (mService) {//此处省略部分系统代码if(dialogToShow != null){// For don't show gaode-map <Stop running> dialog Slog.w(TAG, "------------------handleShowAnrUi ");if(proc != null && proc.info.packageName.equals("com.autonavi.amapauto")){Slog.w(TAG, "------------------Current app is gaode map, don't show <Stop running> dialog");dialogToShow = null;// Just kill the app if there is no dialog to be shown.mService.killAppAtUsersRequest(proc, null);}}}// If we've created a crash dialog, show it without the lock heldif (dialogToShow != null) {dialogToShow.show();}}

从上面博客里知道修改的位置是frameworks\base\services\core\java\com\android\server\am\AppErrors.java，修改后我们可以在Android目录下单编这个模块

android$ mmm frameworks/base/services

编译好后去out/target/product/ac8257_demo/system/framework/目录里面找services.jar，然后推到机器system/framework/下面替换原来的，reboot后执行切换语言高德仍然弹窗报错，查看我们加在handleShowAnrUi方法里面的打印没走，但是看另一条打印

01-01 08:01:01.931   589   748 I AppErrors: Showing crash dialog for package com.autonavi.amapauto u0

2.照例去AppErrors.java里面搜关键字，发现这条打印在handleShowAppErrorUi方法里面，遂在该方法里面添加代码如下

    void handleShowAppErrorUi(Message msg) {AppErrorDialog.Data data = (AppErrorDialog.Data) msg.obj;boolean showBackground = Settings.Secure.getInt(mContext.getContentResolver(),Settings.Secure.ANR_SHOW_BACKGROUND, 0) != 0;AppErrorDialog dialogToShow = null;final String packageName;final int userId;synchronized (mService) {//此处省略部分系统代码if(dialogToShow != null){// For don't show gaode-map <Stop running> dialogSlog.w(TAG, "handleShowAppErrorUi ------------------");if(proc != null && proc.info.packageName.equals("com.autonavi.amapauto")){Slog.w(TAG, "Current app is gaode map, don't show <Stop running> dialog ------------------");dialogToShow = null;// Just kill the app if there is no dialog to be shown.mService.killAppAtUsersRequest(proc, null);}}}// If we've created a crash dialog, show it without the lock heldif (dialogToShow != null) {Slog.i(TAG, "Showing crash dialog for package " + packageName + " u" + userId);dialogToShow.show();}}
