IllegalStateException:WorkManager已经初始化 [英] IllegalStateException: WorkManager is already initialized

问题描述

具有以下依赖性:

dependencies {
    implementation "androidx.work:work-runtime:2.0.1"
    androidTestImplementation "androidx.work:work-testing:2.0.1"
}

第二次运行此代码时:

Configuration config = new Configuration.Builder().build();
WorkManager.initialize(getApplicationContext(), config);

this.workManager = WorkManager.getInstance();

我收到此错误消息:

java.lang.IllegalStateException: WorkManager is already initialized.
Did you try to initialize it manually without disabling WorkManagerInitializer?
See WorkManager#initialize(Context, Configuration) or the class level Javadoc for more information.

并且还会在本机端抛出分段错误:

and it also throws a segmentation fault on the native side:

A/libc: Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR),
fault addr 0x878 in tid 10892 (ova.workmanager),
pid 10892 (ova.workmanager)

这将是WorkManager#initialize(Context, Configuration)的文档.

目的是为了防止在手动初始化过程中发生崩溃(以更改日志级别).如何禁用WorkManagerInitializer?如果可能的话，我不想使用static关键字.

The intent is to prevent the crash during manual initialization (in order to change the log level). How to disable the WorkManagerInitializer? If possible, I do not want to use the static keyword.

推荐答案

这是替换提供商androidx.work.impl.WorkManagerInitializer的方法:

This is how to substitute provider androidx.work.impl.WorkManagerInitializer:

<application>
    ...

    <!-- disable default provider -->
    <provider
        android:name="androidx.work.impl.WorkManagerInitializer"
        android:authorities="${applicationId}.workmanager-init"
        android:exported="false"
        android:enabled="false"/>

    <!-- register custom provider -->
    <provider
        android:name=".CustomWorkManagerInitializer"
        android:authorities="${applicationId}.WorkManagerInit"/>

</application>

Source: Custom Work Manager initialization (in Kotlin).

除非注册其他提供者，否则将给出:

Unless registering another provider, this gives a:

java.lang.IllegalStateException: WorkManager is not initialized properly. The most
likely cause is that you disabled WorkManagerInitializer in your manifest but forgot
to call WorkManager#initialize in your Application#onCreate or a ContentProvider.

src/debug/Manifest.xml中注册的ContentProvider:

public class WorkManagerInit extends ContentProvider {

    @Override
    public boolean onCreate() {
        if(getContext() != null) {
            Configuration config = new Configuration.Builder().build();
            WorkManager.initialize(getContext().getApplicationContext(), config);
        }
        return true;
    }
    ...
}
