java - 如何自动创建和启动梦想服务 android

Question

我正在尝试启动一项梦想服务。目前，这是我的代码:

@SuppressLint("NewApi")
public class DreamLockService extends DreamService {

    private static final String TAG = "DreamLockService";
    public Utility utilObj = new Utility();

    //private Button btnExit;

    private Button btnlogin;
    private EditText lgPass;

    @Override
    public void onAttachedToWindow() {
        super.onAttachedToWindow();
        // Exit dream upon user touch
        setInteractive(true);
        // Hide system UI
        setFullscreen(true);
        // Set the dream layout
        setContentView(R.layout.lockservice);
        //setClickListener();
        Toast.makeText(this, "Lock Service Created", Toast.LENGTH_LONG).show();
    }

    //Use this for initial setup, such as calling setContentView().
    @Override
    public void onDreamingStarted() {
        super.onDreamingStarted();
        // Exit dream upon user touch
        setInteractive(true);
        // Hide system UI
        setFullscreen(true);
        // Set the dream layout
        setContentView(R.layout.lockservice);
        Toast.makeText(this, "Lock Service Created", Toast.LENGTH_LONG).show();
    }

    //Your dream has started, so you should begin animations or other behaviors here.
    public void onDreamingStopped()
    {
        super.onDreamingStopped();
    }

    //Use this to stop the things you started in onDreamingStarted().
    public void onDetachedFromWindow()
    {
        super.onDetachedFromWindow();
    }
}

我无法从其他 Activity 启动梦想服务。这是我使用的:

Intent tempLock = new Intent(MainActivity.this, DreamLockService.class);
//DreamLockService test = new DreamLockService();
startService(tempLock);

我不明白为什么它不起作用。如何从另一项 Activity 启动梦想服务？

Answer 1

要从我们自己的应用程序启动 Dream 服务，请尝试此操作。

    IBinder binder = ServiceManager.getService("dreams");

    Parcel data = Parcel.obtain();
    data.writeInterfaceToken("android.service.dreams.IDreamManager");
    Parcel reply = Parcel.obtain();
    try {
        if (binder != null)
            binder.transact(1, data,reply, Binder.FLAG_ONEWAY);
        else
            Log.e("TAG", "dreams service is not running");
    } catch (RemoteException e) {
        e.printStackTrace();
    } 

要使用此功能，您的应用程序应该是系统应用程序，并且应在 list 文件中具有 dream 权限，并在“设置”中启用 dream 设置。

我试过了，它有效。
