Here is a screenshot of the Test.

Now Here's the funny part, I dont even use Firebase in my app at all. There is no reference to the word "Firebase" when i do a find in path on my entire application. I Do use google cloud services, login and Google app engine though.

Here's my build.gradle file:

Can anyone help me out here ?

回答1:

Thanks for posting the question Sanket. I'm the PM on Firebase Test Lab (formerly Cloud Test Lab). Wanted to let you know that this is a bug on our end that should now be fixed.

It seems that your app is currently using the latest and greatest Google Play Services. We updated our devices to use them last week then we discovered a bug that had us revert to an older version. Right now, we re-deployed the latest Play services on our devices so rerunning your tests should work. If not, please let me know and we'll look into it and fix it.

回答2:

I found a solution that worked for me. I was importing whole google play services 9.0.1 library. The temporary workaround is to import only the APIs that your app actually needs. You can get the whole list of APIs here.

回答3:

with my case: Use FCM and Google map

//for FCM
compile 'com.google.firebase:firebase-messaging:9.4.0'
//for Map
compile 'com.google.android.gms:play-services:9.4.0'

I have fixed: Removed

compile 'com.google.android.gms:play-services:9.4.0'

and Used

compile 'com.google.android.gms:play-services-maps:9.4.0'
compile 'com.google.android.gms:play-services-location:9.4.0'

It worked fine.

回答4:

If this can help other I solved this using this, although this is nowhere linked with Firebase but it actually solved my crash

1. Add compile 'com.android.support:multidex:1.0.1' to app/build.gradle.

2. Add android:name="android.support.multidex.MultiDexApplication" to the application tag in AndroidManifest.xml.

3. If you are using a custom Application class, skip the AndroidManifest.xml and make your Application class extend MultiDexApplication instead of Application.

回答5:

You have to use the com.google.firebase:firebase-ads:9.0.2 AdMob on Android dependencies,

compile 'com.google.firebase:firebase-ads:9.0.2'

and remove your

play-services (com.google.android.gms: play-services:9.0.2)

It works for me!

回答6:

You'd try following Code snippet:

defaultConfig { 
    multiDexEnabled true
}

dependencies {
    compile 'com.android.support:multidex:1.0.0'
}

public class Controller extends Application {

 @Override
    protected void attachBaseContext(Context newBase)
 {
        super.attachBaseContext(newBase);
        MultiDex.install(this);
  } 
}

回答7:

Just downgrade the google play-service dependency to compile 'com.google.android.gms:play-services:8.3.0' and problem will be solved.

回答8:

I hope it's not too late. Firebase was causing trouble, so I excluded it. I just added this on the module gradle:

configurations {
    all*.exclude group: 'com.google.firebase', module: 'firebase-common'
}

回答9:

Turns out my usage of MultiDex was wrong and that causes this error. This should have really been mentioned in the official documentation somewhere.

How to do it the right way :

In Gradle.build (app level)

dependencies {
   compile 'com.android.support:multidex:1.0.1'

In the Manifest, add

<application
        android:name=".Global"
...

In the Application class,

public class Global extends MultiDexApplication {
...
}

In Android 4.4 the solucion was similar like this(https://stackoverflow.com/a/38707231/3377472):

-I have Google Play services revision 33

1) Configure build.gradle and and dependencies

Enabled multidex support and add library of multidex

   android {
        compileSdkVersion 23
        buildToolsVersion '23.0.3'
        defaultConfig {
            applicationId "packagename"
            minSdkVersion 14
            targetSdkVersion 23
            versionCode 1
            versionName "1.0"

            //------- Enabling multidex support----------.
            multiDexEnabled true
        }

        dexOptions {
            javaMaxHeapSize "3g"//use 3Gb of ram to launch android 
        }

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


dependencies {

      compile 'com.android.support:multidex:1.0.1' // 1.0.0

      // if you are using google maps
      compile 'com.google.android.gms:play-services-maps:9.2.0'
      compile 'com.google.android.gms:play-services-location:9.2.0'
}

2)Edit Manifest, and add this android:name

<application
        android:name="android.support.multidex.MultiDexApplication"
        ...
        .....
        activity
             android:name="packagename.Application"
             ....
             ...
       </activity>

3)Application Class

-My application class is:

import android.support.multidex.MultiDex;

public class Application extends AppCompatActivity {


    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //this is the solution 
        MultiDex.install(this);

        setContentView(R.layout.layout_example);

回答11:

Not sure if this helps but I had the same issue using Android sdk 19 and it was driving me insane. I dont use Firebase (at least not purposefully) I am not sure why, but the error ceased when I set "minifyEnabled true" in the gradle config.

I see you have yours commented out in your releases section.

回答12:

If you are using google play services , please make sure that you add the specific service . For example when using maps :

compile 'com.google.android.gms:play-services-maps:x.x.x

instead of

 compile 'com.google.android.gms:play-services:9.6.1'

This will reduce the size of the code and compilation will not require the use of "multidex" feature. If by chance you have already included

{
multiDexEnabled true
}

in your code try removing it and unnecessary library references
