According to https://developer.android.com/build/jdks we should:
1. [use JDK 17 for API 34](https://developer.android.com/build/jdks#compileSdk)
2. [use toolchain](https://developer.android.com/build/jdks#toolchain):
```
We recommend that you always specify the Java toolchain, and either ensure that the specified JDK is installed, or add a toolchain resolver to your build.
```
As we don't want to force people to have JDK 17 on their machine, we apply toolchain resolver that is recommended by Gradle:
```
id("org.gradle.toolchains.foojay-resolver-convention") version("0.4.0")
```
## Test
1. Remove JDK 17 from the computer, remove `jvmToolchain(17)`
2. Run `./gradlew assembleDebug`
3. It should fail with:
```
> Could not create task ':androidApp:compileDebugJavaWithJavac'.
> Failed to calculate the value of task ':androidApp:compileDebugJavaWithJavac' property 'javaCompiler'.
> No matching toolchains found for requested specification: {languageVersion=17, vendor=any, implementation=vendor-specific} for WINDOWS on x86_64.
> No locally installed toolchains match and toolchain download repositories have not been configured.
```
4. restore `jvmToolchain(17)`
5. Run `./gradlew assembleDebug` again
6. It should succeed
