如果您的应用程序中还没有一个类，请创建一个从Application扩展而来的类。

然后执行以下步骤:

public class BaseApplication extends Application { // extend from MultidexApplication if multidex is required by your application 

    @Override
    public void onCreate() {
        super.onCreate();

        /*
         *  Crashlytics is enabled by default,
         *  Disable it for debug builds & USB Debugging
         * */

        if(BuildConfig.DEBUG){ 
            FirebaseCrashlytics.getInstance().setCrashlyticsCollectionEnabled(false);
        }
  }
}

不要忘记在AndroidManifest.xml中添加该类

 <application
        android:name=".BaseApplication"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        ........>

我们可以使用fabric的isDebuggable()方法。

import static io.fabric.sdk.android.Fabric.isDebuggable;

if(! isDebuggable()){
    // set Crashlytics ... 
}

快乐编码:)

我从Crashlytics找到了解决方案(与Fabric集成)

将以下代码放在应用程序类onCreate()中

Crashlytics crashlytics = new Crashlytics.Builder().disabled(BuildConfig.DEBUG).build();
Fabric.with(this, crashlytics);

编辑:

在Crashalitics 2.3及以上版本中，这是不推荐的。正确的代码是:

CrashlyticsCore core = new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build();
Fabric.with(this, new Crashlytics.Builder().core(core).build());

or

Fabric.with(this, new Crashlytics.Builder().core(new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build()).build());

(复制自Crashlytics deprecated method disabled())

EDIT2:

你也可以选择将它添加到gradle中的buildType中。这个命令禁止发送crashlytics映射文件，并为每个构建生成一个ID，这可以加快那些风格的gradle构建。(它不会在运行时禁用Crashlytics。)请看迈克B的回答。

buildTypes {
    release {
           ....
    }
    debug {
        ext.enableCrashlytics = false
    }
}

另一个我喜欢的简单解决方案，因为它不需要不同的清单文件:

步骤1 -在build.gradle中定义清单占位符

android {
    ...
    buildTypes {
        release {
            manifestPlaceholders = [crashlytics:"true"]
        }
        debug {
            manifestPlaceholders = [crashlytics:"false"]
        }
    }
    ...
}

步骤2 -在AndroidManifest.xml中使用它们

<meta-data
        android:name="firebase_crashlytics_collection_enabled"
        android:value="${crashlytics}" />

Add this to your app’s build.gradle: android { buildTypes { debug { // Disable fabric build ID generation for debug builds ext.enableCrashlytics = false ... Disable the Crashlytics kit at runtime. Otherwise, the Crashlytics kit will throw the error: // Set up Crashlytics, disabled for debug builds // Add These lines in your app Application class onCreate method Crashlytics crashlyticsKit = new Crashlytics.Builder() .core(new CrashlyticsCore.Builder().disabled(BuildConfig.DEBUG).build()) .build(); // Initialize Fabric with the debug-disabled crashlytics. Fabric.with(this, crashlyticsKit); In AndroidManifest.xml, add <meta-data android:name="firebase_crashlytics_collection_enabled" android:value="false" />

如果你想要一个可调试的版本，方法如下:

buildTypes {
    release {
        signingConfig signingConfigs.config
        debuggable true //-> debuggable release build
        minifyEnabled true
        multiDexEnabled false
        ext.enableCrashlytics = true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        buildConfigField 'boolean', 'BUILD_TYPE_DEBUG', 'false'
    }
    debug {
        minifyEnabled false
        multiDexEnabled true
        ext.enableCrashlytics = false
        ext.alwaysUpdateBuildId = false
        // Disable fabric build ID generation for debug builds
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        buildConfigField 'boolean', 'BUILD_TYPE_DEBUG', 'true'
    }
}

当你将debuggable设置为true时，你的BuildConfig。DEBUG将初始化为true，这就是为什么我在BuildConfig类中添加了这个变量。

Init织物:

Crashlytics crashlytics = new Crashlytics.Builder()
            // disable crash reporting in debug build types with custom build type variable
            .core(new CrashlyticsCore.Builder().disabled(BuildConfig.BUILD_TYPE_DEBUG).build())
            .build();

    final Fabric fabric = new Fabric.Builder(this)
            .kits(crashlytics)
            //enable debugging with debuggable flag in build type 
            .debuggable(BuildConfig.DEBUG)
            .build();

    // Initialize Fabric with the debug-disabled crashlytics.
    Fabric.with(fabric);
