androidTest：针对 S+（版本 31 及以上）要求在创建 PendingIntent 时指定 FLAG_IMMUTABLE 或 FLAG_MUTABLE 之一

Question

我正在尝试在 androidTest 源集中运行 launchFragmentInHiltContainer。 在代码片段下方运行会导致标题中提到的错误。

@Test
fun mainActivityTest(){
    val scenario = launchFragmentInHiltContainer<CoinInfoFragment> {  }
}

函数 launchFragmentInHiltContainer：

@ExperimentalCoroutinesApi
inline fun <reified T : Fragment> launchFragmentInHiltContainer(
    fragmentArgs: Bundle? = null,
    themeResId: Int = androidx.fragment.testing.R.style.FragmentScenarioEmptyFragmentActivityTheme,
    fragmentFactory: FragmentFactory? = null,
    crossinline action: T.() -> Unit = {}
) {
    val mainActivityIntent = Intent.makeMainActivity(
        ComponentName(
            ApplicationProvider.getApplicationContext(),
            HiltTestActivity::class.java
        )
    ).putExtra(FragmentScenario.EmptyFragmentActivity.THEME_EXTRAS_BUNDLE_KEY, themeResId)

    ActivityScenario.launch<HiltTestActivity>(mainActivityIntent).onActivity { activity ->
        fragmentFactory?.let {
            activity.supportFragmentManager.fragmentFactory = it
        }
        val fragment = activity.supportFragmentManager.fragmentFactory.instantiate(
            Preconditions.checkNotNull(T::class.java.classLoader),
            T::class.java.name
        )
        fragment.arguments = fragmentArgs

        activity.supportFragmentManager.beginTransaction()
            .add(android.R.id.content, fragment, "")
            .commitNow()

        (fragment as T).action()
    }

}

我试图通过以下解决方案解决问题：

• Android Lint：关闭 Missing PendingIntent 可变性，
• 添加：

    // Kotlin + coroutines
    implementation "androidx.work:work-runtime-ktx:$work_version"

    // optional - Test helpers
    androidTestImplementation "androidx.work:work-testing:$work_version"

错误堆栈跟踪：

java.lang.IllegalArgumentException: com.example.cointracker: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

没有任何帮助。有谁知道如何解决这个错误？

更新测试.ext 添加行 androidTestImplementation 'androidx.test.ext:junit:1.1.3' 如果不存在
