2. Quellcode

    public void testPeakPssOfAllApps() throws Exception {

            if (exemptedPackages.contains(packageName)) {
                LogUtil.CLog.d("exempt package " + packageName);
                it.remove();
            }
            else {

            Assert.fail(violations.toString());
        }
    }

Es gibt eine Menge Quellcode, der vollständig in GtsMemoryHostTestCases.jar gekapselt ist. Hier schauen wir uns nur die Testoberfläche an.

Schritt 1. Finden Sie alle Aktivitäten, die den Anforderungen entsprechen

Verwenden Sie ActivityQueryHelper.ALL_APPS_QUERY, um alle Aktivitäten abzufragen, die die Bedingungen erfüllen:

ActivityQueryHelper.java

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

Erfordert alle Aktivitäten, deren Aktion android.intent.action.MAIN und deren Kategorie android.intent.category.LAUNCHER ist.

Schritt 2. Bestimmen Sie die ausgenommenen Pakete

        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"));

Diese ausgenommenen Pakete sind in  der Datei GtsMemoryHostTestCases.dynamic definiert .

Schritt 3. Umfrage zur Bestimmung der endgültigen Aktivität

Ausgenommene Anträge werden im Protokoll ausgedruckt:

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

Schritt 4. Bestimmen Sie die Aktivität, die abschließend überprüft werden kann

Nach Schritt 3 wird die Aktivität, die letztendlich überprüft werden muss, im Protokoll ausgedruckt:

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

 Schritt 5. Bestimmen Sie die Layoutgröße des Geräts und bestimmen Sie den PeakPss

Die Layoutgröße des Geräts wurde im Artikel „Detaillierte Erläuterung des TestPersistentProcessMemory-Fehlers in GTS“ analysiert. Weitere Informationen finden Sie in Abschnitt 2.1 .

Hier wird PeakPss schließlich anhand der Layoutgröße bestimmt. Dieser Attributwert ist   in der Datei GtsMemoryHostTestCases.dynamic definiert:

    ...

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

    ...

Schritt 6. Fragen Sie die zu überprüfenden Aktivitäten ab, ermitteln Sie den Paketnamen und beantragen Sie die Berechtigung android.permission.POST_NOTIFICATIONS .

Schritt 7. Bestimmen Sie den Prozessspeicher und deaktivieren Sie die Benachrichtigungsberechtigungen

Bestimmen Sie den Prozessspeicher mit dem Befehl dumpsys -t 30 meminfo --package packageName und bestimmen Sie den Speicher weiterhin mit der Pattern-Klasse:

        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();

Schritt 8. Die Statistiken überschreiten die maximale PSS

Wenn der Speicher eines Prozesses PeakPss überschreitet, wird er gedruckt und angezeigt.

3. Lösung

Das Fehlerprotokoll in diesem Artikel ist aus dem Hostprotokoll relativ klar:

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.

Der Hauptgrund dafür ist, dass der Start dieser Aktivität nicht den Status „Status: ok“ zurückgibt

Darüber hinaus wird, wie im Artikel „testPersistentProcessMemory failed“ , dieser Fall übersprungen, wenn es sich um ein Nicht-GO-Gerät handelt, was bedeutet, dass ein solcher fehlgeschlagener Fall nur auf der GO-Plattform angezeigt wird:
