Trying to run Spark in Android: MethodHandle.invoke and MethodHandle.invokeExact are only supported starting with Android O

问题

以下是翻译好的内容：

  1. 我需要在 Android 中生成一个 Webhook URL。最初我尝试了 Spring Framework，但实现起来似乎相当困难，我只想公开一个单一的 Webhook URL，所以我寻找了一个轻量级的框架。我现在尝试使用 [spark-java][1]，但我无法让它运行起来。
  3. 错误信息：
  5.     被压制的异常：java.util.concurrent.ExecutionException: com.android.tools.r8.errors.a: MethodHandle.invoke 和 MethodHandle.invokeExact 仅支持从 Android O 开始（--min-api 26）

I need to generate a webhook url in android. Initially I tried Spring Framework, but it seems quite difficult to implement and I'm just looking to expose a single webhook url so I looked for a lightweight framework. I've now been trying to use spark-java, but I can't get it to run.

Error:

  • Gradle version is 6.6.1

  • In Project Structure, I already checked the defined Java SDK and it's correctly set to 1.8

  • Minimum Android SDK I'm using is API 16

我已经能够在Android上运行一个Spark服务器。以下是我的build.gradle文件：

  1. apply plugin: 'com.android.application'
  3. android {
  4.     compileSdkVersion 29
  5.     buildToolsVersion "29.0.3"
  7.     defaultConfig {
  8.         applicationId "com.mycom.appname"
  9.         minSdkVersion 27
  10.         targetSdkVersion 29
  11.         versionCode 1
  12.         versionName "1.0"
  14.         testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
  15.     }
  17.     buildTypes {
  18.         release {
  19.             minifyEnabled false
  20.             proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
  21.         }
  22.     }
  23.     compileOptions {
  24.         sourceCompatibility = 1.8
  25.         targetCompatibility = 1.8
  26.     }
  27. }
  29. dependencies {
  30.     implementation fileTree(dir: 'libs', include: ['*.jar'])
  31.     implementation 'androidx.appcompat:appcompat:1.0.2'
  32.     implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
  34.     implementation 'com.sparkjava:spark-core:2.9.2'
  36.     testImplementation 'junit:junit:4.12'
  37.     androidTestImplementation 'androidx.test.ext:junit:1.1.1'
  38.     androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
  39. }

我们都在使用Spark 2.9.2版本。我对gradle不是太熟悉，但我注意到表明依赖关系的方式有所不同（compile "com.sparkjava:spark-core:2.9.2"与implementation 'com.sparkjava:spark-core:2.9.2'）。

英文:

I've been able to run a Spark server on Android. Here is my build.gradle.

  1. apply plugin: 'com.android.application'
  3. android {
  4.     compileSdkVersion 29
  5.     buildToolsVersion "29.0.3"
  7.     defaultConfig {
  8.         applicationId "com.mycom.appname"
  9.         minSdkVersion 27
  10.         targetSdkVersion 29
  11.         versionCode 1
  12.         versionName "1.0"
  14.         testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
  15.     }
  17.     buildTypes {
  18.         release {
  19.             minifyEnabled false
  20.             proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
  21.         }
  22.     }
  23.     compileOptions {
  24.         sourceCompatibility = 1.8
  25.         targetCompatibility = 1.8
  26.     }
  27. }
  29. dependencies {
  30.     implementation fileTree(dir: 'libs', include: ['*.jar'])
  31.     implementation 'androidx.appcompat:appcompat:1.0.2'
  32.     implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
  34.     implementation 'com.sparkjava:spark-core:2.9.2'
  36.     testImplementation 'junit:junit:4.12'
  37.     androidTestImplementation 'androidx.test.ext:junit:1.1.1'
  38.     androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
  39. }

We are both using Spark 2.9.2. I'm not too familiar with gradle but I notice that the way we indicate the dependency on it is different (compile "com.sparkjava:spark-core:2.9.2" vs. implementation 'com.sparkjava:spark-core:2.9.2').
