android wear睡眠软件,如何在睡眠模式下唤醒Android Wear？

每次我从处理设备收到消息时,我都在使用PowerManger来唤醒我的可穿戴设备.

别忘了发布PowerManager.WakeLock

public abstract class WatchFaceActivity extends Activity {

private PowerManager.WakeLock mWakeLock;

private Handler mWakeLockHandler;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_clock_watch_face);

PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);

mWakeLock = powerManager.newWakeLock((PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP), "MyWakelockTag");

mWakeLockHandler = new Handler();

IntentFilter messageFilter = new IntentFilter("message-forwarded-from-data-layer");

MessageReceiver messageReceiver = new MessageReceiver();

LocalBroadcastManager.getInstance(this).registerReceiver(messageReceiver, messageFilter);

}

public class MessageReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

if (!mWakeLock.isHeld()) {

mWakeLock.acquire();

}

mWakeLockHandler.removeCallbacksAndMessages(null);

mWakeLockHandler.postDelayed(mReleaseRunnable, 5000);

}

}

private Runnable mReleaseRunnable = new Runnable() {

@Override

public void run() {

mWakeLock.release();

}

};

@Override

protected void onDestroy() {

super.onDestroy();

mWakeLockHandler.removeCallbacksAndMessages(null);

mWakeLock.release();

}

}

并在您的清单中允许WAKE_UP权限.
