在project和Gradle构建非常小的apk

标签： android android-gradle build.gradle

我之前遇到过这个问题，因为ClassNotFoundException我的应用程序无法正常工作。为了解决这个问题，我创建了一个新项目并且它工作了一段时间，直到再次进行一些更改导致此错误再次出现。我注意到调试apk非常小，大小约为980千字节，通常它应该是2兆字节左右。我通过在应用程序的gradle文件中删除调试下的minifyEnabled true来修复它。调试apk大小恢复正常并再次工作，直到我添加library导致错误再次出现。调试apk的大小减少到980千字节。我已经清理，在删除app文件夹中的.gradle文件夹和build文件夹后重建，仍然存在此问题。

的build.gradle：

apply plugin: 'com.android.application'

android {
compileSdkVersion 25
defaultConfig {
    applicationId "com.prajjwal.myfreight"
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }

    debug {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:25.4.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.android.support:design:25.4.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
compile 'info.hoang8f:fbutton:1.0.5'
compile 'com.amulyakhare:com.amulyakhare.textdrawable:1.0.1'
compile 'com.rengwuxian.materialedittext:library:2.0.3'
compile files('libs/jtds-1.2.8-a46da18a7c06f34fb19c38538665cbe1.jar')
}

我使用的gradle版本是4.1。
