根据官方Android开发人员文档，
我正在尝试使用活动识别。但是，当我尝试获得检测到的过渡更新时，我会遇到错误。对于所有其他活动类型，我没有问题。
这是我创建ActivityTransitionRequest
的代码@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(this, ActivityRecognizedService.class);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, 0);
Task<Void> task =
ActivityRecognition.getClient(this).
requestActivityTransitionUpdates(createTransitionsRequest(), pendingIntent);
task.addOnSuccessListener(
new OnSuccessListener<Void>() {
@Override
public void onSuccess(Void result) {
Log.d(TAG, "success");
// Handle success
}
}
);
task.addOnFailureListener(
new OnFailureListener() {
@Override
public void onFailure(Exception e) {
Log.d(TAG, "failure", e);
// Handle error
}
}
);
// ActivityRecognition.getClient(this).requestActivityUpdates(1000L, pendingIntent);
}
private ActivityTransitionRequest createTransitionsRequest() {
List<ActivityTransition> transitions = new ArrayList<>();
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.IN_VEHICLE)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_ENTER)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.IN_VEHICLE)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_EXIT)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.STILL)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_ENTER)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.STILL)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_EXIT)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.ON_FOOT)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_ENTER)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.ON_FOOT)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_EXIT)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.WALKING)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_ENTER)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.WALKING)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_EXIT)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.RUNNING)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_ENTER)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.RUNNING)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_EXIT)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.ON_BICYCLE)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_ENTER)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.ON_BICYCLE)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_EXIT)
.build());
// The following activity transitions will result in an exception.
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.UNKNOWN)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_ENTER)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.UNKNOWN)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_EXIT)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.TILTING)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_ENTER)
.build());
transitions.add(
new ActivityTransition.Builder()
.setActivityType(DetectedActivity.TILTING)
.setActivityTransition(ActivityTransition.ACTIVITY_TRANSITION_EXIT)
.build());
return new ActivityTransitionRequest(transitions);
}
这是我正在使用的意图。
public class ActivityRecognizedService extends IntentService {
private static final String TAG = ActivityRecognizedService.class.getSimpleName();
public ActivityRecognizedService() {
super("ActivityRecognizedService");
}
public ActivityRecognizedService(String name) {
super(name);
}
@Override
protected void onHandleIntent(@Nullable Intent intent) {
if(ActivityRecognitionResult.hasResult(intent)) {
ActivityRecognitionResult result = ActivityRecognitionResult.extractResult(intent);
handleDetectedActivities( result.getProbableActivities() );
}
}
private void handleDetectedActivities(List<DetectedActivity> probableActivities) {
for( DetectedActivity activity : probableActivities ) {
switch( activity.getType() ) {
case DetectedActivity.IN_VEHICLE: {
Log.e( TAG, "In Vehicle: " + activity.getConfidence() );
break;
}
case DetectedActivity.ON_BICYCLE: {
Log.e( TAG, "On Bicycle: " + activity.getConfidence() );
break;
}
case DetectedActivity.ON_FOOT: {
Log.e( TAG, "On Foot: " + activity.getConfidence() );
break;
}
case DetectedActivity.RUNNING: {
Log.e( TAG, "Running: " + activity.getConfidence() );
break;
}
case DetectedActivity.STILL: {
Log.e( TAG, "Still: " + activity.getConfidence() );
break;
}
case DetectedActivity.TILTING: {
Log.e( TAG, "Tilting: " + activity.getConfidence() );
break;
}
case DetectedActivity.WALKING: {
Log.e( TAG, "Walking: " + activity.getConfidence() );
break;
}
case DetectedActivity.UNKNOWN: {
Log.e( TAG, "Unknown: " + activity.getConfidence() );
break;
}
}
}
}
}
这是我得到的例外：

任何帮助将不胜感激。
过渡API支持以下活动：
IN_VEHICLE ON_BICYCLE RUNNING STILL WALKING
过渡API仅支持以下活动： - in_vehicle - on_bicycle- 跑步- 仍然 - 步行
删除UNKNOWN和TILTING的过渡。他们不支持。
