我正在构建一个简单的android应用,用户可以在其中发送/接收电子邮件。我正在使用Java Mail API。我的代码在eclipse中运行良好,但是现在我正在使用Android Studio,但遇到了构建错误。
一个答案建议我将其添加到build.gradle文件中。但这没有帮助
android {
packagingOptions {
exclude 'Meta-INF/DEPENDENCIES'
exclude 'Meta-INF/LICENSE'
exclude 'Meta-INF/LICENSE.txt'
exclude 'Meta-INF/license.txt'
exclude 'Meta-INF/NOTICE'
exclude 'Meta-INF/NOTICE.txt'
exclude 'Meta-INF/notice.txt'
exclude 'Meta-INF/ASL2.0'
}
}
这是我的build.gradle文件
apply plugin: 'com.android.application'
android {
compileSdkVersion 29
buildToolsVersion "29.0.2"
defaultConfig {
applicationid "com.example.javaemailapp"
minSdkVersion 24
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs',include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
implementation files('/Users/redacted/Downloads/javamail-1.4.4/mail.jar')
implementation files('/Users/redacted/Downloads/jaf-1.1.1/activation.jar')
}
我只想测试一下“发送”按钮是否在我的应用程序中有效,但是当我单击在Android Studio中运行时,出现此错误:
使用操作系统独立路径“ Meta-INF / gfprobe-provider.xml”找到了多个文件
