如何解决将图像添加到可绘制文件夹时，Android资源编译失败错误
我是Android新手。我做了一个简单的应用程序。当我尝试生成签名包时，出现以下错误。
代码：
build.gradle（项目）
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath "com.android.tools.build:gradle:4.1.0"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
build.gradle（模块）
plugins {
id 'com.android.application'
}
android {
compileSdkVersion 30
buildToolsVersion "30.0.2"
defaultConfig {
applicationId "com.example.cricketchirps"
minSdkVersion 21
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.2.1'
implementation 'androidx.constraintlayout:constraintlayout:2.0.2'
testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

我尝试清理并重建项目，使缓存无效/重新启动。但是我仍然遇到错误。
我从drawable文件夹中删除了temp1.png并完全删除了ImageView。工作正常。没有错误。
任何人都可以告诉我为什么出现此错误以及如何解决该错误吗？
Android Studio：4.1
构建工具：30.0.2
版本版本：6.5
Android Gradle插件版本：4.1.0
更新：
我刚刚将图像从png转换为webp格式。它解决了我的问题。 要将图像从png转换为Android Studio中的webp，请打开图像>右键单击>转换为webp ...
解决方法
尝试动态设置图像资源（即在.java或.kt文件中）
JAVA-
ImageView img = findViewById("R.id.imageView2");
img.setImageDrawable(getResources().getDrawable(R.drawable.temp1));
科特琳-
imageView2.setImageDrawable(resources.getDrawable(R.drawable.temp1))
