Android(安卓)JobIntentService

package zhang.phil;import android.content.Context;import android.content.Intent;import android.os.Handler;import android.os.SystemClock;import android.util.Log;import android.widget.Toast;import androidx.core.app.JobIntentService;public class DemoService extends JobIntentService {    public static final String TAG = "后台服务";    private final static int jobId = 0xa001;    @Override    public void onCreate() {        super.onCreate();        Log.d(TAG, "onCreate");    }    public static void enqueueWork(Context context, Intent work) {        enqueueWork(context, DemoService.class, jobId, work);    }    @Override    protected void onHandleWork(Intent intent) {        String s = intent.getStringExtra(TAG);        for (int i = 0; i < 3; i++) {            SystemClock.sleep(5000);            Log.d(TAG, Thread.currentThread().getId()+":"+s + "->" + i);        }        toast("任务结束");    }    @Override    public void onDestroy() {        super.onDestroy();        Log.d(TAG, "onDestroy");    }    private final Handler mHandler = new Handler();    private void toast(final CharSequence text) {        mHandler.post(new Runnable() {            @Override            public void run() {                Toast.makeText(DemoService.this, text, Toast.LENGTH_SHORT).show();            }        });    }}

需要在Androidmanifest.xml定义服务：

上层使用：

package zhang.phil;import androidx.appcompat.app.AppCompatActivity;import android.content.Intent;import android.os.Bundle;import android.util.Log;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        Log.d(DemoService.TAG, Thread.currentThread().getId() + ",MainActivity线程id");        Intent intent = new Intent();        intent.putExtra(DemoService.TAG, "zhangphil");        DemoService.enqueueWork(this, intent);    }    @Override    protected void onDestroy() {        super.onDestroy();        Log.d(DemoService.TAG, "onDestroy,MainActivity");    }}
