我已经安装了 Google Play 服务并创建了一个 Hello World 应用程序来测试一切是否正常，我认为应用程序大小太大:4.98 MB。
我正在使用 Android Studio，并且我已按照 android 开发人员网站中详细说明的说明进行操作。

这是我的毕业文件:

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services:4.3.23'
}

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
    public static final *** NULL;
}

-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}

-keepnames class * implements android.os.Parcelable {
   public static final ** CREATOR;
}

最佳答案

不，这不正常 - 我的 GPSTest app 的早期版本在使用 Proguard 进行混淆后，包括用于 map 的 Google Play 服务只有 808KB - 当前版本(添加另一个库后)在混淆后约为 1,497KB。

我建议使用以下步骤从命令行导出 APK，以避免 Android Studio 出现潜在问题:

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.preference.Preference

-keepclasseswithmembers class * {
    native <methods>;
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

-dontwarn **CompatHoneycomb
-dontwarn **CompatCreatorHoneycombMR2
-dontwarn **AccessibilityServiceInfoCompatJellyBeanMr2
-dontwarn android.support.v4.view.**
-dontwarn android.support.v4.media.**
-dontwarn com.actionbarsherlock.internal.**
-keep class android.support.v4.** { *; }
-keepattributes *Annotation*
-keep public class * extends android.view.View
-keep public class * extends android.view.ViewGroup
-keep public class * extends android.support.v4.app.Fragment

-keepclassmembers class * extends com.actionbarsherlock.ActionBarSherlock {
    <init>(android.app.Activity, int);
}
