Android-runtime: Problems w/ Google Play Services

[filipemendes1994]

Hello, community. I've been doing a plugin to discover Google Fitness API. However, i found some problems that i would appreciate your help.

I've already manage to create successfully a GoogleApiClient connected to FitnessAPI, using a Google Account. I've followed the instructions provided for Google for this particular API. The problems began when I tried to query fitness data to the API, getting this error catched w/ adb logcat

When i tried to look for solution, i realized it might be a problem in some google services dependencies and i tried everything i could, w/out any success. Finally, after huge turnarounds, i find this when i run npm run demo.android

I'm running Nativescript 3.1.2 w/ tns-core-modules 3.1.0 and tns-android 3.1.0. I've Google Play Services version 43 installed in AndroidSDK. I leave my include.gradle down here

android {
    buildTypes {
      release {
          minifyEnabled true
          proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      }
    }
    productFlavors {
        "nativescript-google-fit" {
            dimension "nativescript-google-fit"
        }
    }
}

dependencies {
    compile 'com.google.android.gms:play-services-base:9.4.0'
    compile 'com.google.android.gms:play-services-fitness:9.4.0'
} 

Feel free to clone my repo and give me some precious advice.

Hey @filipemendes1994, is there a particular reason you put a proguard configuration here? A nested, likely private class is missing, according to the log. A possible reason for that is the class being referenced and used in JavaScript, is cleaned up and removed by ProGuard.

[filipemendes1994]

@Pip3r4o i checked my proguard twice and I didn't realized where I could be removing that library, but be free to check. Also, I tried to comment the proguard configuration and the problem remain the same.

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

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

-keep @interface android.support.annotation.Keep
-keep @android.support.annotation.Keep class *
-keepclasseswithmembers class * {
  @android.support.annotation.Keep <fields>;
}
-keepclasseswithmembers class * {
  @android.support.annotation.Keep <methods>;
}

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

-keep @interface com.google.android.gms.common.util.DynamiteApi
-keep public @com.google.android.gms.common.util.DynamiteApi class * {
  public <fields>;
  public <methods>;
}

-dontwarn android.security.NetworkSecurityPolicy

I think that I copy-and-paste the proguard configuration from Android Google API Fitness Sample

@filipemendes1994 a repro sample would be much appreciated so we can troubleshoot the problem.

[filipemendes1994]

@Pip3r4o the problem remains but it is not critical. The exception throws every first time I invoke that method but the plugin stills running. If you want to see, check this repo and execute tns run demo.ng.android.

@filipemendes1994 do you still have the above problem, as I tried with the provided repo but couldn't reproduce it?
