2. source code

源码比较多，都封装在 GtsMemoryHostTestCases.jar 中。这里只是来看下 test 接口。

step1. 查找所有符合要求的activity

通过 ActivityQueryHelper.ALL_APPS_QUERY 来查询所有符合条件的 activities：

ActivityQueryHelper.javaALL_APPS_QUERY = new ActivityQuery().setAction("android.intent.action.MAIN").setCategory("android.intent.category.LAUNCHER");

要求Action 为 android.intent.action.MAIN，category 为 android.intent.category.LAUNCHER 的所有 Activities。

step2. 确定免除的package

        final Set<String> exemptedPackages = new HashSet<String>();exemptedPackages.addAll(this.readExemptions("gallery_exemptions"));exemptedPackages.addAll(this.readExemptions("streaming_music_apps"));exemptedPackages.addAll(this.readExemptions("streaming_video_apps"));exemptedPackages.addAll(this.readExemptions("all_apps_memory_exemptions"));

这些可以免除的 package 都定义在 GtsMemoryHostTestCases.dynamic 文件中。

step3. 轮询确定最终的activity

被免除的应用会在 log 中打印出来：

09-14 10:02:54 D/AllAppsMemoryHostTest: exempt activity com.android.chrome/com.google.android.apps.chrome.Main
09-14 10:02:54 D/AllAppsMemoryHostTest: exempt activity com.google.android.apps.photosgo/.home.HomeActivity
09-14 10:02:54 D/AllAppsMemoryHostTest: exempt package com.google.android.youtube
09-14 10:02:54 D/AllAppsMemoryHostTest: exempt activity org.codeaurora.dialer/com.android.dialer.main.impl.MainActivity
09-14 10:02:54 D/AllAppsMemoryHostTest: exempt package com.google.android.apps.nbu.files

step4. 确定最终可以check 的activity

在经过 step3 之后，log 中会打印出最终需要 check 的acitivity：

09-14 10:02:54 D/AllAppsMemoryHostTest: These apps will be checked: com.android.mms/.ui.ConversationList,
com.android.settings/.Settings,
com.android.soundrecorder/.SoundRecorder,
com.android.vending/.AssetBrowserActivity,
com.google.android.apps.assistant/.go.MainActivity,
com.google.android.apps.messaging/.ui.ConversationListActivity,
com.google.android.apps.tachyon/.MainActivity,
com.google.android.calculator/com.android.calculator2.Calculator,
com.google.android.calendar/com.android.calendar.AllInOneActivity,
com.google.android.contacts/com.android.contacts.activities.PeopleActivity,
com.google.android.deskclock/com.android.deskclock.DeskClock,
com.google.android.dialer/.extensions.GoogleDialtactsActivity,
org.codeaurora.snapcam/com.android.camera.CameraLauncher,
com.caf.fmradio/.FMRadio,
com.google.android.apps.mapslite/com.google.maps.lite.twa.MapsLiteTwaLauncherActivity,
com.google.android.apps.searchlite/.ui.SearchActivity

 step5. 确定设备的 layout size，并确定peakPss

设备的layout size 在《GTS 中testPersistentProcessMemory fail 详解》一文中已经分析过，详细看第 2.1 节。

这里最终根据 layout size 确定 peakPss，该属性值都定义  GtsMemoryHostTestCases.dynamic 文件中：

    ...<entry key="max_memory_all_apps_2gb_hd"><value>153600</value></entry>...

step6. 轮询待check的activities，确定package name，并申请 android.permission.POST_NOTIFICATIONS 权限。

step7. 确定进程内存，并关闭notification 权限

通过 dumpsys -t 30 meminfo --package packageName 的命令确定进程内存，依然通过 Pattern 类确定内存：

        final List<String> usages = new ArrayList<String>();final Matcher matcher = Pattern.compile("TOTAL\\s+([\\d]+)").matcher(output);while (matcher.find()) {usages.add(matcher.group(1));}Assert.assertFalse("Could not get meminfo total for " + packageName, usages.isEmpty());return usages.stream().mapToLong((ToLongFunction<? super Object>)Long::valueOf).sum();

step8. 统计超过 max pss

如果有进程的 memory 超过了 peakPss，则会打印显示

3. 解决方案

本文中的 error log 从host log 中比较清晰：

09-14 10:12:33 W/NativeDevice: Command: 'shell am start -W -S -f 10008000 'com.google.android.apps.mapslite/com.google.maps.lite.twa.MapsLiteTwaLauncherActivity'' on 'd4081bc5' went over its timeout for outputing a response.
09-14 10:14:34 W/NativeDevice: Command: 'shell am start -W -S -f 10008000 'com.google.android.apps.mapslite/com.google.maps.lite.twa.MapsLiteTwaLauncherActivity'' on 'd4081bc5' went over its timeout for outputing a response.
09-14 10:16:34 W/NativeDevice: Command: 'shell am start -W -S -f 10008000 'com.google.android.apps.mapslite/com.google.maps.lite.twa.MapsLiteTwaLauncherActivity'' on 'd4081bc5' went over its timeout for outputing a response.
09-14 10:16:34 I/TestFailureListener: FailureListener.testFailed com.google.android.memory.gts.AllAppsMemoryHostTest#testPeakPssOfAllApps false...09-14 10:16:34 W/GranularRetriableTestWrapper: com.android.tradefed.device.DeviceUnresponsiveException[DEVICE_UNRESPONSIVE|520751|LOST_SYSTEM_UNDER_TEST]: Attempted shell am start -W -S -f 10008000 'com.google.android.apps.mapslite/com.google.maps.lite.twa.MapsLiteTwaLauncherActivity' multiple times on device d4081bc5 without communication success. Aborting.

根本原因是启动这个 acitivity 没有返回 Staatus: ok 的状态
