Java 带有Headless JS的Android后台服务不起作用

到目前为止，我已经实施了：

MainApplication.java:

    @Override
    public void onCreate() {
    super.onCreate();
    SoLoader.init(this, /* native exopackage */ false);
    initializeFlipper(this); // Remove this line if you don't want Flipper enabled

    Intent service = new Intent(getApplicationContext(), MyTaskService.class);

    getApplicationContext().startService(service);
  }

package com.myApp;

import android.content.Intent;
import android.os.Bundle;
import com.facebook.react.HeadlessJsTaskService;
import com.facebook.react.bridge.Arguments;
import com.facebook.react.jstasks.HeadlessJsTaskConfig;
import javax.annotation.Nullable;
import com.facebook.react.bridge.WritableMap;

public class MyTaskService extends HeadlessJsTaskService {

   @Override
  protected @Nullable HeadlessJsTaskConfig getTaskConfig(Intent intent) {

Bundle extras = intent.getExtras();
  WritableMap data = extras != null ? Arguments.fromBundle(extras) : null;
return new HeadlessJsTaskConfig(
    "SomeTaskName", // Use the registered headless Task here
    data,
    5000);
}
}

  <service android:name="com.myApp.MyTaskService" />

AppRegistry.registerHeadlessTask('SomeTaskName', () => SomeTaskName);

MyTaskService.java:

    @Override
    public void onCreate() {
    super.onCreate();
    SoLoader.init(this, /* native exopackage */ false);
    initializeFlipper(this); // Remove this line if you don't want Flipper enabled

    Intent service = new Intent(getApplicationContext(), MyTaskService.class);

    getApplicationContext().startService(service);
  }

package com.myApp;

import android.content.Intent;
import android.os.Bundle;
import com.facebook.react.HeadlessJsTaskService;
import com.facebook.react.bridge.Arguments;
import com.facebook.react.jstasks.HeadlessJsTaskConfig;
import javax.annotation.Nullable;
import com.facebook.react.bridge.WritableMap;

public class MyTaskService extends HeadlessJsTaskService {

   @Override
  protected @Nullable HeadlessJsTaskConfig getTaskConfig(Intent intent) {

Bundle extras = intent.getExtras();
  WritableMap data = extras != null ? Arguments.fromBundle(extras) : null;
return new HeadlessJsTaskConfig(
    "SomeTaskName", // Use the registered headless Task here
    data,
    5000);
}
}

  <service android:name="com.myApp.MyTaskService" />

AppRegistry.registerHeadlessTask('SomeTaskName', () => SomeTaskName);

AndroidManifest.xml:

    @Override
    public void onCreate() {
    super.onCreate();
    SoLoader.init(this, /* native exopackage */ false);
    initializeFlipper(this); // Remove this line if you don't want Flipper enabled

    Intent service = new Intent(getApplicationContext(), MyTaskService.class);

    getApplicationContext().startService(service);
  }

package com.myApp;

import android.content.Intent;
import android.os.Bundle;
import com.facebook.react.HeadlessJsTaskService;
import com.facebook.react.bridge.Arguments;
import com.facebook.react.jstasks.HeadlessJsTaskConfig;
import javax.annotation.Nullable;
import com.facebook.react.bridge.WritableMap;

public class MyTaskService extends HeadlessJsTaskService {

   @Override
  protected @Nullable HeadlessJsTaskConfig getTaskConfig(Intent intent) {

Bundle extras = intent.getExtras();
  WritableMap data = extras != null ? Arguments.fromBundle(extras) : null;
return new HeadlessJsTaskConfig(
    "SomeTaskName", // Use the registered headless Task here
    data,
    5000);
}
}

  <service android:name="com.myApp.MyTaskService" />

AppRegistry.registerHeadlessTask('SomeTaskName', () => SomeTaskName);

SomeTaskName.js（注册代码）：

    module.exports = async (taskData) => {
    alert('test');
    console.log('Went to background');
 }

---

使用此代码，它会运行，但会立即关闭应用程序，并且不会显示任何错误。你知道为什么会发生这种情况，为什么我不能调用alert and console.log吗？

在

MainApplication.java

文件中添加

Intent

，并在

SoLoader.init（）之前调用函数
getApplicationContext（）
行，你错过了这个调用

HeadlessJsTaskService.acquireWakeLockNow(context)

根据文件要求：

如果要从{@code-HeadlessJsTaskService}启动{@code-HeadlessJsTaskService}
BroadcastReceiver}（例如。*处理推送通知），请确保
在从*{@link返回之前调用{@link#acquireWakeLockNow}
BroadcastReceiver#onReceive}，以确保设备不会转到
在*服务启动前睡眠

你解决问题了吗？还是不为我工作。。我怎样才能知道任务是否被执行。。。无法控制台或无法放置警报语句？
