Android开发之——开发中的错误及解决办法

2.1 Cannot inline bytecode built with JVM target 1.8

现象

Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target

解决方案

android {

…

compileOptions {

sourceCompatibility = 1.8

targetCompatibility = 1.8

}

kotlinOptions {

jvmTarget = “1.8”

}

}

2.2 Unable to find EOCD signature

现象1

Execution failed for task ‘:app:packagexxxxRelease’.

A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade

Unable to find EOCD signature

现象2

Execution failed for task ‘:app:packageGame_ZHRelease’.

A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade

java.lang.IllegalArgumentException (no error message)

原因

依赖中添加了有关ABI相关的配置，打包输出时，未指定ABI版本

[](https://blog.youkuaiyun.com/Calvin_zhou/article/de

tails/117333108)解决办法（添加ABI输出）

import com.android.build.OutputFile

static def releaseTime() {

return new Date().format(“yyyyMMdd”, TimeZone.getTimeZone(“GMT+8”))

}

buildTypes {

release {

minifyEnabled true

shrinkResources true

proguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.pro’

applicationVariants.all { variant ->

variant.outputs.all { output ->

project.ext { appName = ‘YourApkName’ }

outputFileName = “$appName-${output.getFilter(OutputFile.ABI)}-$variant.name-${variant.versionName}.apk”

}

}

}

}

2.3 failed to read PNG signature: file does not start with PNG signature

现象

AAPT: error: failed to read PNG signature: file does not start with PNG signature.

解决办法

在app/build.gradle文件中加以下代码后，重构项目

android {

compileSdkVersion 28

flavorDimensions “mode”

aaptOptions.cruncherEnabled = false

aaptOptions.useNewCruncher = false

defaultConfig {

}

2.4 Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8

现象(项目创建时)

An exception occurred applying plugin request [id: ‘com.android.application’]

Failed to apply plugin ‘com.android.internal.application’.

You can try some of the following options:

• changing the IDE settings.

• changing the JAVA_HOME environment variable.

• changing org.gradle.java.home in gradle.properties.

解决办法

依次点击：File——>Project Struct——>SDK Location——>JDK location was moved to Gradle Settings，在打开的对话框中，将Gradle JDK修改为11
