* EventLog: Disable event writing in production buildsDanny Lin2023-01-031-10/+64
| | | | | | | | | | | | | | | | | | | When opening and closing activities in Settings, a measurably significant amount of CPU time is spent writing to the EventLog, as reported by simpleperf: 0.01% /system/lib64/libandroid_runtime.so android::EventLogHelper<(log_id)2, &(android::kEventLogEventClass)>::writeEventArray(_JNIEnv*, _jobject*, int, _jobjectArray*) We have no use for EventLog events in production builds, so disable event writing entirely on non-debuggable builds. To avoid having to check ro.debuggable in native code and pay the overhead of a JNI call for every event, perform checks on the Java side and make the native method implementations private for delegation. Test: simpleperf record -a; verify that EventLogHelper no longer appears in sample hits Change-Id: I3505c460f234d9a5038bd1f9d41ce911697ca76e (cherry picked from commit 34800851c95ddb4c9f5b680225647eb3cbd4da2f)
* Add maxTargetSdk restriction to unused APIs.Mathew Inwood2020-10-291-1/+2
| | | | | | | | | | | | | | | | | | | These are APIs that have @UnsupportedAppUsage but for which we don't have any evidence of them currently being used, so should be safe to remove from the unsupported list. This is a resubmit of ag/12929664 with some APIs excluded that caused test failures; see bugs 171886397, 171888296, 171864568.

* | Add @Nullable annotation to the parameter of Object.equals() methods.Roman Kalukiewicz2020-10-151-1/+1
|/ | | | | | | | | | | | | | | | | | Those annotations could be inferred by some tools (like Kotlin), but the https://checkerframework.org/ doesn't check inherited annotations complaining about all equals() invocations that get nullable argument. The change was generated by running find . -name \*.java | xargs sed -i 's/public boolean equals(Object /public boolean equals(@Nullable Object /' in the frameworks/base directory and by automatically adding and formatting required imports if needed. No manual edits. Bug: 170883422 Test: Annotation change only. Should have not impact. Exempt-From-Owner-Approval: Mechanical change not specific to any component.

* Support security logging on org-owned managed profile devicesRubin Xu2020-02-201-13/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When security logging is enabled on org-owned profile devices, Security events will be redacted to preserve privacy on the personal profile as follows: * TAG_ADB_SHELL_CMD Shell command will be redacted. * TAG_MEDIA_MOUNT * TAG_MEDIA_UNMOUNT The media's volume name will be redacted. * TAG_APP_PROCESS_START * TAG_CERT_AUTHORITY_INSTALLED * TAG_CERT_AUTHORITY_REMOVED * TAG_KEY_GENERATED * TAG_KEY_IMPORT * TAG_KEY_DESTRUCTION * TAG_KEY_INTEGRITY_VIOLATION Only events happening inside the managed profile will be returned to the admin.

* Request logs from logd with 3s overlap to avoid missing events.Pavel Grafov2017-03-211-0/+23
| | | | | | | | | | | | | | | | Example: If we got a batch with timestamps [1, 4, 8] and an event with timestamp 7 was delayed and was added to the buffer later, if we request the next batch starting from timestamp 8 or 9 that event will be lost. The last 3 seconds of events are kept and checked against the next batch.

Gut and deprecate EventLogTags, which unfortunately was put into the public SDK (an oversight). Include the functionality in EventLog proper, in a simpler and easier to use manner.
