我正在制作一个可以在单击按钮时写入Firebase数据库的应用程序。 该应用程序可以在模拟器上运行,但不能在我的物理设备上运行。 这是主要的活动代码:

public class MainActivity extends AppCompatActivity {
private Firebase fled1;
Button on;
Button off;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Firebase.setAndroidContext(this);

        on=  findViewById(R.id.on);
        off=  findViewById(R.id.off);

        on.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                fled1 = new Firebase("https://iotapp-6y3n8.firebaseio.com/");
                Firebase fled1Child = fled1.child("S1");
                fled1Child.setValue("1");
            }
        });

        off.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                fled1 = new Firebase("https://iotapp-6y3n8.firebaseio.com/");   
                Firebase fled1Child = fled1.child("S1");
                fled1Child.setValue("0");
            }
        });
    }

这是我的清单文件,我已添加了所有必需的权限:

  <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.lalitahuja.iotbutton">
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name="com.example.lalitahuja.iotbutton.MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

这是构建Gradle文件:

apply plugin: 'com.android.application'

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

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    //noinspection GradleCompatible
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-core:16.0.8'
    implementation 'com.google.firebase:firebase-database:16.1.0'
    implementation 'com.crashlytics.sdk.android:crashlytics:2.9.7'
    implementation 'com.google.firebase:firebase-auth:16.2.0'
    implementation 'com.firebase:firebase-client-android:2.5.2'
}
apply plugin: 'com.google.gms.google-services'

我得到的错误:
