admob广告后如何减小应用程序大小? [英] how to reduce app size increased after admob ads?

问题描述

before adding google-play-services to my project its size was just 900kb and after adding lib of play services it is now 4.01MB. its terrible. for 900kb app ads of 3MB is too much.

help me as soon as possible. my app is finished now.

I tried reading about proguard but unable to understand. someone please give me step by step tutorial to reduce app size.

解决方案

You don't need to edit google-play-services.jar file. Use proguard to keep only needed class files.

Create proguard.txt file in your module directory (e.g. app/) and write following lines in that file:

-keep public class com.google.android.gms.ads.** {
    public *;
}

-keep public class com.google.ads.** {
    public *;
}

-dontwarn com.google.android.gms.**

Now write following lines in your module's build.gradle file (for e.g. app/build.gradle):

...
buildTypes {
    debug {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard.txt'
    }
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard.txt'
    }
    ...
}
...

Sync your gradle file and build & run your app. Now see the difference in size of your app.
