                    }
                }
            });
        }


    }
}

it is showing the below log i cant understand it do i have to add some dependencies to make this work, i can run the app on android device, but when i try to launch the activityit is getting crashed

what could i correct to make that activity too work this is the dependencies file

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.penaliz"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true;
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:28.0.0'

}
apply plugin: 'com.google.gms.google-services'

Answer 1

该错误可能是因为这些依赖项具有不同的版本号:

implementation 'com.google.firebase:firebase-auth:16.1.0'
implementation 'com.google.firebase:firebase-core:16.0.7'
implementation 'com.google.firebase:firebase-database:16.0.6'
implementation 'com.google.firebase:firebase-storage:16.0.5'

所以尝试将它们更改为如下所示:

implementation 'com.google.firebase:firebase-auth:16.1.0'
implementation 'com.google.firebase:firebase-core:16.1.0'
implementation 'com.google.firebase:firebase-database:16.1.0'
implementation 'com.google.firebase:firebase-storage:16.1.0'

还在您的依赖项中添加实现“com.android.support:multidex:1.0.3”。
