android - Activity Fence 在 Awareness API 中不起作用

Question

我尝试使用 Google Awareness API 实现 Activity Fence。但是没有检测到用户 Activity 的变化。不过，耳机护栏按预期工作。

ActivityFenceActivity

public class ActivityFenceActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks {

private static final String FENCE_RECEIVER_ACTION = "FENCE_RECEIVE";
private static final String FENCE_WALKING_KEY = "walkingKey";
private static final String FENCE_RUNNING_KEY = "runningKey";
private static final String TAG = ActivityFenceActivity.class.getSimpleName();

private GoogleApiClient googleApiClient;
private TextView activityTextView;
private BroadcastReceiver activityFenceReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(final Context context, final Intent intent) {
        Toast.makeText(context, "Recieved", Toast.LENGTH_SHORT).show();
        FenceState fenceState = FenceState.extract(intent);

        if (TextUtils.equals(fenceState.getFenceKey(), FENCE_WALKING_KEY)) {
            switch (fenceState.getCurrentState()) {
                case FenceState.TRUE:
                    activityTextView.setText("User is walking");
                    break;
                case FenceState.FALSE:
                    activityTextView.setText("User is not walking");
                    break;
                case FenceState.UNKNOWN:
                    activityTextView.setText("Activity state unknown");
                    break;
            }
        } else if (TextUtils.equals(fenceState.getFenceKey(), FENCE_RUNNING_KEY)) {
            switch (fenceState.getCurrentState()) {
                case FenceState.TRUE:
                    activityTextView.setText("User is running");
                    break;
                case FenceState.FALSE:
                    activityTextView.setText("User is not running");
                    break;
                case FenceState.UNKNOWN:
                    activityTextView.setText("Activity state unknown");
                    break;
            }
        }
    }
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_activity_fence);

    activityTextView = (TextView) findViewById(R.id.activityTextView);

    googleApiClient = new GoogleApiClient.Builder(ActivityFenceActivity.this)
            .addApi(Awareness.API)
            .addConnectionCallbacks(this)
            .build();
    googleApiClient.connect();

    findViewById(R.id.register_fence).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            registerActivityFence();
        }
    });

    findViewById(R.id.unregister_fence).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            unregisterActivityFence();
        }
    });


}

@Override
public void onConnected(@Nullable final Bundle bundle) {
    Log.d(TAG, "Google API connected");

}

@Override
public void onConnectionSuspended(final int i) {
    Log.d(TAG, "Google API connection suspended");

}

@Override
protected void onStart() {
    super.onStart();
    registerReceiver(activityFenceReceiver, new IntentFilter(FENCE_RECEIVER_ACTION));
}

@Override
protected void onStop() {
    super.onStop();

    unregisterReceiver(activityFenceReceiver);
    unregisterActivityFence();
}

private void registerActivityFence() {
    AwarenessFence walkingFence = DetectedActivityFence.during(DetectedActivityFence.WALKING);
    AwarenessFence runningFence = DetectedActivityFence.during(DetectedActivityFence.RUNNING);

    PendingIntent fencePendingIntent = PendingIntent.getBroadcast(this,
            0,
            new Intent(FENCE_RECEIVER_ACTION),
            0);

    Awareness.FenceApi.updateFences(googleApiClient, new FenceUpdateRequest.Builder()
            .addFence(FENCE_WALKING_KEY, walkingFence, fencePendingIntent).build())
            .setResultCallback(new ResultCallbacks<Status>() {
                @Override
                public void onSuccess(@NonNull final Status status) {
                    Toast.makeText(ActivityFenceActivity.this,
                            "Fence registered successfully",
                            Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onFailure(@NonNull final Status status) {
                    Toast.makeText(ActivityFenceActivity.this,
                            "Cannot register activity fence.",
                            Toast.LENGTH_SHORT).show();
                }
            });

    Awareness.FenceApi.updateFences(googleApiClient, new FenceUpdateRequest.Builder()
            .addFence(FENCE_RUNNING_KEY, runningFence, fencePendingIntent).build());

}

private void unregisterActivityFence() {
    Awareness.FenceApi.updateFences(
            googleApiClient,
            new FenceUpdateRequest.Builder()
                    .removeFence(FENCE_WALKING_KEY)
                    .removeFence(FENCE_RUNNING_KEY)
                    .build()).setResultCallback(new ResultCallbacks<Status>() {
        @Override
        public void onSuccess(@NonNull Status status) {

如果耳机栅栏有效而 Activity 栅栏不起作用，也许您只是忘记在 list 中添加权限？

<uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION"/>
