Question

我有一个应用程序，当我将android studio更新到3.4.2版本并更新gradle时，无论如何，我不得不强行更改某些库，例如将androidx用到appcomaptibility和注释中，之后，应用程序的同步没有任何问题，但是当我想在设备上运行应用程序时，出现以下错误。我进行搜索，将Java版本添加到gradle等，但没有成功，再次出现相同的错误。我该如何解决这个问题？

错误：仅从Android O（--min-api 26）开始支持MethodHandle.invoke和MethodHandle.invokeExact

gradle的ORMDroid库：

buildscript {
ext.java_version = JavaVersion.VERSION_1_8

    jcenter()
    google()

    classpath 'com.android.tools.build:gradle:3.4.2'
    classpath 'com.google.gms:google-services:4.0.2'
}
}
apply plugin: 'android-library'

dependencies {
implementation fileTree(dir: 'libs', include: '*.jar')
}

android {

    sourceCompatibility java_version
    targetCompatibility java_version

        renderscript.srcDirs = ['src']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }

    // Move the tests to tests/java, tests/res, etc...
    androidTest.setRoot('tests')

    // Move the build types to build-types/<type>
    // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
    // This moves them out of them default location under src/<type>/... which would
    // conflict with src/ being used by the main source set.
    // Adding new build types or product flavors should be accompanied
    // by a similar customization.
    debug.setRoot('build-types/debug')
    release.setRoot('build-types/release')
}
defaultConfig {

不确定是否仍然有用，但是在这种情况下，您只需要在等级中更新minSdkVersion。

Android O要求minSdkVersion为26，因此您可以照此更新。

minSdkVersion 26

错误：从Android O（--min-api 26）开始仅支持MethodHandle.invoke和MethodHandle.invokeExact
