Since 44847bf4e, when we upgraded our JUnit version, the JUnit
exclusions have probably not been necessary. e0ac97c4f upgraded
Robolectric to a version that had the auto.service problem fixed.
Allows using Android's LocalSocket via a Socket adapter. Such an adapter
isn't generally 100% safe, since some methods may not have any effect,
but we know what methods are called by gRPC's okhttp transport and can
update the adapter or the transport as appropriate.
This is the latest version of the plugin supported by the Gradle version
in use at the moment (7.6).
Note that this also upgrades the R8 optimizer to a version (4.0.48) that
now uses "full mode" optimization by default.
This also splits off Android projects to run under Java 11 (Gradle
plugin requirement) while the other projects continue to run under Java
8.
This can avoid creating an additional 736 tasks (previously 502 out of
1591 were not created). That's not all that important as the build time
is essentially the same, but this lets us see the poor behavior of the
protobuf plugin in our own project and increase our understanding of how
to avoid task creation when developing the plugin. Of the tasks still
being created, protobuf is the highest contributor with 165 tasks,
followed by maven-publish with 76 and appengine with 53. The remaining
59 are from our own build, but indirectly caused by maven-publish.
This moves our depedencies into a plain file that can be read and
updated by tooling. While the current tooling is not particularly better
than just using gradle-versions-plugin, it should put us on better
footing. gradle-versions-plugin is actually pretty nice, but will be
incompatible with Gradle 8, so we need to wait a bit to see what the
future holds.
Left libraries as an alias for libs to reduce the commit size and make
it easier to revert if we don't end up liking this approach.
We're using Gradle 7.3.3 where it was an incubating fetaure. But in
Gradle 7.4 is became stable.
This fixes up cda0e9d to be compatible with Proguard without
configuration. Since the methods are now accessed directly there is no
need for manual -keep configuration.
Doing any reflection on OkHttpChannelBuilder requires that all methods
can have their arguments resolved. We'd like to make okhttp an optional
dependency (to support okhttp 2 and 3/4 simultaneously). But making
okhttp optional means we can no longer construct OkHttpChannelBuilder
reflectively. We swap to the Provider that doesn't have this problem.
See #8971.
Note that ManagedChannelProvider itself only exposes its methods as
protected, so they wouldn't be accessible. However OkHttpChannelProvider
has its methods public. It is an open question of whether
ManagedChannelProvider's methods should become public, but in any case
we can hide a public OkHttpChannelProvider inside a package-private
class so it is only accessable via reflection. So this code assuming
public methods doesn't prevent future implementation hiding.
failOnVersionConflict has never been good for us. It is equivalent to
Maven dependencyConvergence which we discourage our users to use because
it is too tempermental and _creates_ version skew issues over time.
However, we had no real alternative for determining if our deps would be
misinterpeted by Maven.
failOnVersionConflict has been a constant drain and makes it really hard
to do seemingly-trivial upgrades. As evidenced by protobuf/build.gradle
in this change, it also caused _us_ to introduce a version downgrade.
This introduces our own custom requireUpperBoundDeps implementation so
that we can get back to simple dependency upgrades _and_ increase our
confidence in a consistent dependency tree.
This change can have large impact from two aspects:
1. It calls out a _large_ impact on the _few_ Java 7 users.
2. It may have _small_ impact on the _many_ Android users.
https://github.com/grpc/grpc-java/issues/4671 tracks gRPC's removal of
Java 7 support. We are quite eager to drop Java 7 support as that would
allow using new language features like default methods. Guava is also
dropping Java 7 support and starting in 30.1 it will warn when used on
Java 7. The purpose of the warning is to help discover users that are
negatively impacted by dropping Java 7 before it becomes a bigger
problem.
The Guava logging check was implemented in such a way that there is an
optional class that uses Java 8 bytecode. While the class is optional at
runtime, the Android build system notices when dexing and fails if
Java 8 language featutres are not enabled. We believe this will not be a
problem for most Android users, but they may need to add to their build:
```
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
```

Bumps target SDK version of grpc-android, grpc-cronet, grpc-android-interop-testing to API 29. Major related changes are:
- Migrated android.support to androidx, which is required for Android Q.
- android.net.NetworkInfo is deprecated in SDK 29, suppressed compiler warnings as it is needed for supporting old Android versions.
- Robolectric requires Java 9+ for Android 29, which causes unit tests in grpc-cronet fail. Added annotation to emulate Android 28 for grpc-cronet's test.
- Upgraded Android dependencies accordingly in android-interop-testing.
On Android, there is a race between making new RPCs and reconnecting after network comes back. If the former happens first, RPCs fail immediately. This is because resetConnectBackoff() does not update the picker before trying to reconnect and new RPCs are sent with the old picker, which fails RPCs immediately.
In this change, we move to use enterIdle(), which updates the channel picker to cause new RPCs being buffered (while subchannels are in reconnecting), at the moment network recovers. Hopefully, this can avoid RPCs being dropped prematurely in network recovery.
- Use gradle configuration `api` for dependencies that are part of grpc public api signatures.
- Replace deprecated gradle configurations `compile`, `testCompile`, `runtime` and `testRuntime`.
- With minimal change in dependencies: If we need dep X and Y to compile our code, and if X transitively depends on Y, then our build would still pass even if we only include X as `compile`/`implementation` dependency for our project. Ideally we should include both X and Y explicitly as `implementation` dependency for our project, but in this PR we don't add the missing Y if it is previously missing.
For Android version 28, some constants in ConnectivityManager have been deprecated such as ConnectivityManager. CONNECTIVITY_ACTION, ConnectivityManager. TYPE_WIFI, ConnectivityManager. TYPE_MOBILE, etc. In grpc-android, they are used for supporting legacy SDK connectivity state monitoring (and its unit tests). They work as intended for legacy SDK versions. So we suppress those warnings for the target SDK version 28.
Add grpc-android into main build. grpc-android will be built if Gradle option skipAndroid is false. This change also migrates deprecated Robolectric methods to androidx.test methods.
* Added missing Javadoc for public methods, deprecate fromBuilder and replace with usingBuilder.
* Removed unnecessary final keyword for static methods.
* call usingBuilder in deprecated fromBuilder
* Changed Javadoc description for usingBuilder method.
* android: fix Javadoc symbol/class not found errors
* Removed redundant join, files API can already handle list.
* Replace usage of javaCompile with javaCompileProvider
* Avoid afterEvaluate by filling javadocs.classpath in android configuration.
* Construct FileCollection via files(Closure), which delays the file resolution.
This fixes the following warning when building grpc-android:
WARNING: API 'variant.getJavaCompiler()' is obsolete and has been replaced with 'variant.getJavaCompileProvider()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration-avoidance.
To determine what is calling variant.getJavaCompiler(), use -Pandroid.debug.obsoleteApi=true on the command line to display a stack trace.
com.github.dcendents:android-maven-gradle-plugin is incompatible with
Gradle 5 and the project hasn't seen any activity in over a year, so it
seems unlikely to get fixed.
We want to use maven-publish anyway, since that's what we use elsewhere.
This resolves#5523
While bumping `com.android.tools.build:gradle:3.1.2` to `3.3.0`, some other plugins/artifacts/maven repo/buildscripts have to be updated:
- gradle (wrapper) need to upgrade to 4.10.x
- protobuf gradle plugin need to bump a version compatible with gradle version.
- need add `google()` and `jcenter()` repos for android (otherwise `com.android.tools.build:aapt2:3.3.0x` and `trove4j` will not be found resp.)
- need to accept license for Android "build-tools;28.0.3" in kokoro env.
