我将现有的android项目升级到API级别31。我使用Java作为语言。我换了build.gradle
compileSdkVersion 31
defaultConfig {
applicationId 'com.app.app'
minSdkVersion 16
targetSdkVersion 31
versionCode 91
versionName '4.0.1'
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}但我无法用AVD或真正的设备来调试这个应用程序。我得到了这个错误。

An API level of 31 is not supported by this compiler. Please use an API level of 30 or earlier我想我需要更新编译器，我怎么做呢？

尝试将其添加到build.gradle文件中：
android {
...
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}

您使用的gradle版本似乎无法使用D8。但是改变gradle版本可能是个大问题。尤其是为了维护老项目。而且D8似乎是用来减少APK文件大小的。这只是警告而不是错误。所以，合理的行动可能是..。忽略这条信息。:)
