Android开发中的错误及解决办法总结

一 概述

开发工具升级，依赖库，运行环境(jdk)等都会造成项目运行出现错误

掌握开发中常见错误现象和问题及解决办法，能节省时间

本文将不定期更新

二 错误类

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

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

三 警告类

3.1 The ‘kotlin-android-extensions’ Gradle plugin is deprecated

现象

The 'kotlin-android-extensions' Gradle plugin is deprecated. Please use this migration guide (https://goo.gle/kotlin-android-extensions-deprecation) to start working with View Binding (https://developer.android.com/topic/libraries/view-binding) and the 'kotlin-parcelize' plugin.

解决办法

删除 apply plugin: 'kotlin-android-extensions'
使用binding赋值
binding.name.text = viewModel.nameString

3.2 Warning: Mapping new ns xx/common/02 to old ns xx/common/01

现象

Warning: Mapping new ns http://schemas.android.com/repository/android/common/02 to old ns http://schemas.android.com/repository/android/common/01
Warning: Mapping new ns http://schemas.android.com/repository/android/generic/02 to old ns http://schemas.android.com/repository/android/generic/01
Warning: Mapping new ns http://schemas.android.com/sdk/android/repo/addon2/02 to old ns http://schemas.android.com/sdk/android/repo/addon2/01
Warning: Mapping new ns http://schemas.android.com/sdk/android/repo/repository2/02 to old ns http://schemas.android.com/sdk/android/repo/repository2/01
Warning: Mapping new ns http://schemas.android.com/sdk/android/repo/sys-img2/02 to old ns http://schemas.android.com/sdk/android/repo/sys-img2/01

解决办法(buildToolsVersion引起-修改前)

compileSdkVersion 30
buildToolsVersion "30.0.3"

去掉buildToolsVersion或将buildToolsVersion版本降低

compileSdkVersion 30
buildToolsVersion "30.0.2"

四 工具类

4.1 Task list not build

现象

解决办法

1. 点击Task list not build，进入Settings——>Experimental，将Do not build Gradle task list duraing Gradle sync前面的勾选去掉，并应用
2. 点击Sync Project with Gradle Files同步一下项目
