早期版本运行良好,但是当我更新库版本时出现了错误
这是app.gradle文件,也已通过编译版本27和28进行了测试
android {
compileSdkVersion 26
defaultConfig {
applicationId "com.example.test"
minSdkVersion 19
targetSdkVersion 26
multiDexEnabled true
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.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
}
packagingOptions {
exclude 'META-INF/proguard/androidx-annotations.pro'
}
}
将依赖项更改为androidX版本后,出现了问题
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'
implementation 'com.google.android.material:material:1.1.0-alpha04'
implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha03'
implementation 'com.lsjwzh:materialloadingprogressbar:0.5.8-RELEASE'
implementation 'com.jakewharton:butterknife:10.1.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:10.1.0'
testImplementation 'junit:junit:4.12'

androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
在build.gradle文件中
classpath 'com.android.tools.build:gradle:3.1.2'
