java - IllegalStateException:WorkManager 已经初始化

Question

具有这些依赖性:

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

第二次运行这段代码时:

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.

它还会在 native 端引发段错误:

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 documentation对于 WorkManager#initialize(Context, Configuration)。

目的是为了防止在手动初始化时崩溃(为了改变日志级别)。如何禁用 WorkManagerInitializer？如果可能，我不想使用 static 关键字。

Answer 1

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

<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>

来源:Custom Work Manager initialization (在 Kotlin 中)。

除非注册另一个提供者，否则会出现:

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.

以及在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;
    }
    ...
}
