I use Android Studio IDE (Gradle) And Import all google-play-services. is it possible to import part of it ?

Answer 1

Assuming you're using AS and Gradle as build script / dependency management

To import whole Google Play Services you're using dependency like this:

compile 'com.google.android.gms:play-services:7.8.0'

Which includes all the services resources and classes, it's huge list:

+--- com.google.android.gms:play-services:7.8.0
|    +--- com.google.android.gms:play-services-ads:7.8.0
|    |    +--- com.google.android.gms:play-services-base:7.8.0
|    |    |    \--- com.android.support:support-v4:22.2.0 -> 22.2.1
|    |    |         \--- com.android.support:support-annotations:22.2.1

|    +--- com.google.android.gms:play-services-panorama:7.8.0
|    |    \--- com.google.android.gms:play-services-base:7.8.0 (*)
|    +--- com.google.android.gms:play-services-plus:7.8.0
|    |    \--- com.google.android.gms:play-services-base:7.8.0 (*)
|    +--- com.google.android.gms:play-services-safetynet:7.8.0
|    |    \--- com.google.android.gms:play-services-base:7.8.0 (*)
|    +--- com.google.android.gms:play-services-vision:7.8.0
|    |    \--- com.google.android.gms:play-services-base:7.8.0 (*)
|    +--- com.google.android.gms:play-services-wallet:7.8.0
|    |    +--- com.google.android.gms:play-services-base:7.8.0 (*)
|    |    +--- com.google.android.gms:play-services-identity:7.8.0 (*)
|    |    \--- com.google.android.gms:play-services-maps:7.8.0 (*)
|    \--- com.google.android.gms:play-services-wearable:7.8.0
|         \--- com.google.android.gms:play-services-base:7.8.0 (*)

To downsize it, you have three options:

• Add only part of it, you need, eg. com.google.android.gms:play-services-maps:7.8.0
• Exclude parts you don't want

like this:

compile('com.google.android.gms:play-services:7.8.0') {
    exclude module: 'play-services-fitness'
    exclude module: 'play-services-games'
    exclude module: 'play-services-wallet'
    exclude module: 'play-services-safetynet'
    exclude module: 'play-services-appinvite'
    exclude module: 'play-services-wearable'
    exclude module: 'play-services-cast'
}

• Or use Proguard (minifyEnabled), which should trim from the resulting APK resources and classes, that are not used or reffered to
