JobIntentService无法正常启动

问题描述 投票:2回答:3

在com.example.project.packageA包中,我有一个扩展JobIntentService定义的类,如下所示:

public class MyService extends JobIntentService {

    static final int JOB_ID = 1000;
    static final String TAG =MyService.class.getSimpleName();

    public static void enqueueWork(Context context, Intent work) {
        enqueueWork(context, MyService.class, JOB_ID, work);
    }

    @Override
    public int onStartCommand(@Nullable Intent intent, int flags, int startId) {
        return super.onStartCommand(intent, flags, startId);
    }

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

        @Override
    public void onDestroy() {
        super.onDestroy();
    }

    /**
     * We have received work to do.  The system or framework is already
     * holding a wake lock for us at this point, so we can just go.
     */
    @Override
    protected void onHandleWork(Intent intent) {
        Log.i(TAG, "Started onHandleWork");
        String value = intent.getExtras().getString("Key");
        Log.i(TAG, value);
    }

}

在另一个包中:com.example.project.packageB;我想把这个服务叫做后台启动,所以我做到了:

Intent it = new Intent();
it.setComponent(new ComponentName("com.example.project", "com.example.project.packageA.MyService"));
it.putExtra("Key", "Value");
MyService.enqueueWork(context, it);
Log.d(TAG, "Call successful");

我还在清单文件中包含以下权限:

<service
    android:name="com.example.project.MyService"
    android:permission="android.permission.BIND_JOB_SERVICE"
    android:exported="true"/>

但是,当我运行我的程序时,它似乎不是服务启动。我可以看到日志消息“Call successful”,但我看不到onHandleWork函数的日志消息。我是以错误的方式开始服务吗?

android service jobservice

您无需在意图中使用组件名称。尝试删除此行:

it.setComponent(new ComponentName("com.example.project", "com.example.project.packageA.MyService"));

你的代码应该是这样的:

Intent it = new Intent();
it.putExtra("Key", "Value");
MyService.enqueueWork(context, it);
Log.d(TAG, "Call successful");

考虑像这样开始;

Intent it = new Intent(context, MyService.class);
it.putExtra("key", "value");
MyService.enqueueWork(context, it);

在Android的更高版本中,Google引入了Doze功能来优化设备的电池寿命。 (不确定他们引入了哪个版本)您需要将其添加到您忽略电池优化的意图中

//禁用电池优化

Intent intent = new Intent(this,SeriesService.class);
String packageName = getPackageName();
PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
    if (pm.isIgnoringBatteryOptimizations(packageName))
            intent.setAction(Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS);
    else {      intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
            intent.setData(Uri.parse("package:" + packageName));
    }
startService(intent);

我在我的OnePlus 5上运行了这个(运行Android派)并且它可以工作

以防万一我已经启动它后添加了如何调用我的服务

Context con = getView().getContext();//activity context
Intent intent = new Intent(con,SeriesService.class);
intent.setAction(SOME_ACTION);
intent.putExtra(KEY,data);
SeriesService.enqueueWork(con,intent);
