+ * Custom ArgumentMatcher for TetherOffloadRuleParcel. This is needed because generated stable
+ * AIDL classes don't have equals(), so we cannot just use eq(). A custom assert, such as:
+ *
+ * private void checkFooCalled(StableParcelable p, ...) {
+ * ArgumentCaptor<@FooParam> captor = ArgumentCaptor.forClass(FooParam.class);
+ * verify(mMock).foo(captor.capture());
+ * Foo foo = captor.getValue();
+ * assertFooMatchesExpectations(foo);
+ * }
+ *
+ * almost works, but not quite. This is because if the code under test calls foo() twice, the
+ * first call to checkFooCalled() matches both the calls, putting both calls into the captor,
+ * and then fails with TooManyActualInvocations. It also makes it harder to use other mockito
+ * features such as never(), inOrder(), etc.
+ *
+ * This approach isn't great because if the match fails, the error message is unhelpful
+ * (actual: "android.net.TetherOffloadRuleParcel@8c827b0" or some such), but at least it does
+ * work.
+ *
+ * TODO: consider making the error message more readable by adding a method that catching the
+ * AssertionFailedError and throwing a new assertion with more details. See
+ * NetworkMonitorTest#verifyNetworkTested.
+ *
+ * See ConnectivityServiceTest#assertRoutesAdded for an alternative approach which solves the
+ * TooManyActualInvocations problem described above by forcing the caller of the custom assert
+ * method to specify all expected invocations in one call. This is useful when the stable
+ * parcelable class being asserted on has a corresponding Java object (eg., RouteInfo and
+ * RouteInfoParcelable), and the caller can just pass in a list of them. It not useful here

# This will launch Intellij project for Nearby module.
```
+Note, the setup above may fail to index classes defined in proto, such
+that all classes defined in proto shows red in IDE and cannot be auto-completed.
+To fix, you can mannually add jar files generated from proto to the class path
+as below. First, find the jar file of presence proto with
+```sh
+ls $ANDROID_BUILD_TOP/out/soong/.intermediates/packages/modules/Connectivity/nearby/service/proto/presence-lite-protos/android_common/combined/presence-lite-protos.jar
+```
+Then, add the jar in IDE as below.
+1. Menu: File > Project Structure
+2. Select Modules at the left panel and select the Dependencies tab.
+3. Select the + icon and select 1 JARs or Directories option.
+4. Select the JAR file found above, make sure it is checked in the beginning square.
+5. Click the OK button.
+6. Restart the IDE to re-index.
## Build and Install
```sh
-$ source build/envsetup.sh && lunch <TARGET>
-$ m com.google.android.tethering.next deapexer
-$ $ANDROID_BUILD_TOP/out/host/linux-x86/bin/deapexer decompress --input \
- ${ANDROID_PRODUCT_OUT}/system/apex/com.google.android.tethering.next.capex \
- --output /tmp/tethering.apex
-$ adb install -r /tmp/tethering.apex
+For master on AOSP (Android) host
+$ source build/envsetup.sh
+$ lunch aosp_oriole-trunk_staging-userdebug
+$ m com.android.tethering
+$ $ANDROID_BUILD_TOP/out/host/linux-x86/bin/deapexer decompress --input $ANDROID_PRODUCT_OUT/system/apex/com.android.tethering.capex --output /tmp/tethering.apex
+$ adb install /tmp/tethering.apex
+$ adb reboot
+
+NOTE: Developers should use AOSP by default, udc-mainline-prod should not be used unless for Google internal features.
+For udc-mainline-prod on Google internal host
+Build unbundled module using banchan
+$ source build/envsetup.sh
+$ banchan com.google.android.tethering mainline_modules_arm64
+$ m apps_only dist
+$ adb install out/dist/com.google.android.tethering.apex
+$ adb reboot
+Ensure that the module you are installing is compatible with the module currently preloaded on the phone (in /system/apex/com.google.android.tethering.apex). Compatible means:
+
+1. Same package name
+2. Same keys used to sign the apex and the payload
+3. Higher version
+
+See go/mainline-local-build#build-install-local-module for more information
```
+
+## Build and Install from tm-mainline-prod branch
+When build and flash the APEX from tm-mainline-prod, you may see the error below.
+```
+[INSTALL_FAILED_VERSION_DOWNGRADE: Downgrade of APEX package com.google.android.tethering is not allowed. Active version: 990090000 attempted: 339990000])
+```
+This is because the device is flashed with AOSP built from master or other branches, which has
+prebuilt APEX with higher version. We can use root access to replace the prebuilt APEX with the APEX
+built from tm-mainline-prod as below.
+1. adb root && adb remount -R
+2. cp tethering.next.apex com.google.android.tethering.apex
+3. adb push com.google.android.tethering.apex /system/apex/
+4. adb reboot
+After the steps above, the APEX can be reinstalled with adb install -r.
+(More APEX background can be found in https://source.android.com/docs/core/ota/apex#using-an-apex.)
+
+## Build APEX to support multiple platforms
+If you need to flash the APEX to different devices, Pixel 6, Pixel 7, or even devices from OEM, you
+can share the APEX by ```source build/envsetup.sh && lunch aosp_arm64-userdebug```. This can avoid
+ re-compiling for different targets.

+ie. there were no changes between R/S/T and R/S/T QPR3, and no change between U and U QPR1.
+
+Note: Sv2 sdk/api level is actually 32, it just didn't change anything wrt. bpf, so doesn't matter.
+
+
+Key takeaways:
+
+= R bpfloader:
+ - CHOWN + SYS_ADMIN
+ - asynchronous startup
+ - platform only
+ - proc file setup handled by initrc
+
+= S bpfloader
+ - adds NET_ADMIN
+ - synchronous startup
+ - platform + mainline tethering offload
+
+= T bpfloader
+ - platform + mainline networking (including tethering offload)
+ - supported btf for maps via exec of btfloader
+
+= U bpfloader
+ - proc file setup moved into bpfloader binary
+ - explicitly specified user and groups:
+ group root graphics network_stack net_admin net_bw_acct net_bw_stats net_raw system
+ user root
+
+= U QPR2 bpfloader
+ - drops support of btf for maps
+ - invocation of /system/bin/netbpfload binary, which after handling *all*
+ networking bpf related things executes the platform /system/bin/bpfloader
+ which handles non-networking bpf.
+
+Note that there is now a copy of 'netbpfload' provided by the tethering apex
+mainline module at /apex/com.android.tethering/bin/netbpfload, which due
+to the use of execve("/system/bin/bpfloader") relies on T+ selinux which was
+added for btf map support (specifically the ability to exec the "btfloader").

+ # However, while the rlimit is per-thread, the accounting is system wide.

+ # from the default (wembley: 64kB) to the maximum (1M) per log buffer.
+ # Otherwise buffer will overflow before you manage to dump it and you'll get useless logs.
+ #
+ # 2. comment out 'reboot_on_failure reboot,bpfloader-failed' below
+ # 3. rebuild/reflash/reboot
+ # 4. as the device is booting up capture bpfloader logs via:
+ # adb logcat -s 'bpfloader:*' 'LibBpfLoader:*' 'NetBpfLoad:*' 'NetBpfLoader:*'
+ #
+ # something like:
+ # $ adb reboot; sleep 1; adb wait-for-device; adb root; sleep 1; adb wait-for-device; adb logcat -s 'bpfloader:*' 'LibBpfLoader:*' 'NetBpfLoad:*' 'NetBpfLoader:*'
