How can the sports app keep the end-to-side background alive to make the sports record more complete?

When you're working out , Have you ever encountered such a situation ？ Worked hard for hours , But found App Stopped running , This movement has not been recorded App On , Thus, the opportunity to view the complete motion data is lost ？

Sports App It is through the sensor of mobile phone or wearable device , To identify the motion state and feed back to the user ,App Whether the mobile phone can always run in the background is a key factor affecting the integrity of sports data . In order to meet the needs of users to view complete motion data , Sports App All hope to keep alive in the background of the equipment , And the motion data of users are recorded in real time through sensors . But most mobile phone manufacturers are trying to save power , Once the application is in the background, it will be restricted or even forcibly closed by the system , As a result, the motion record finally presented to the user is incomplete .

Sports App To realize the end-to-end and back-end protection , There are usually two solutions ：

1. Guide the user to manually set the keep alive on the mobile phone , If battery optimization is turned off , allow App Background operation . The disadvantage of this method is that the operation steps are complex , User learning costs are high .

2. Through integration Huawei sports health service To solve this problem , The sports health service provides back-end support for keeping alive sports records API, After integrating this capability, the application can keep running in the background of Huawei mobile phones during the user's exercise , So as to realize the uninterrupted movement record during the user's exercise .

How to realize the backstage keep alive function ？ Here are the detailed integration steps .

Integration steps

1. Please refer to The development of preparation Complete the application Health Kit service , Check the data permission required for the product and integrate SDK.

2. To call the background keep alive function, you need to apply for the permission to read the motion records , Again Get user authorization Complete permission application .

3. To ensure that your application is not frozen by the system , You need to start a front desk service Foreground services, Call... In the foreground service ActivityRecordsController Method to create a motion record that is allowed to run in the background ;

4. call ActivityRecordsController Of beginActivityRecord The interface starts to allow motion recording to run in the background , By default, the application will be allowed to run in the background 10 minute ;

//  Please note that this by Activity object ActivityRecordsController activityRecordsController = HuaweiHiHealth.getActivityRecordsController(this); // 1. New tectonic movement record start time long startTime = Calendar.getInstance().getTimeInMillis(); // 2. structure ActivityRecord object , Set the motion recording start time  ActivityRecord activityRecord = new ActivityRecord.Builder()     .setId("MyBeginActivityRecordId")     .setName("BeginActivityRecord")     .setDesc("This is ActivityRecord begin test!")     .setActivityTypeId(HiHealthActivities.RUNNING)     .setStartTime(startTime, TimeUnit.MILLISECONDS)     .build(); // 3. Build the page displayed during the running of application motion record , MyActivity It needs to be replaced with its own Activity class ComponentName componentName = new ComponentName(this, MyActivity.class);// 4. Build a motion recording background running state change listener OnActivityRecordListener activityRecordListener = new OnActivityRecordListener() {    @Override    public void onStatusChange(int statusCode) {        Log.i("ActivityRecords", "onStatusChange statusCode:" + statusCode);    }};// 5. Call to start a new motion record API Interface beginActivityRecordTask<Void> task1 = activityRecordsController.beginActivityRecord(activityRecord, componentName, activityRecordListener); // 6. Add startup ActivityRecord success  task1.addOnSuccessListener(new OnSuccessListener<Void>() {     @Override     public void onSuccess(Void aVoid) {         Log.i("ActivityRecords", "MyActivityRecord begin success");     } // 7. Add startup ActivityRecord Failure }).addOnFailureListener(new OnFailureListener() {     @Override     public void onFailure(Exception e) {         String errorCode = e.getMessage();         String errorMsg = HiHealthStatusCodes.getStatusCodeMessage(Integer.parseInt(errorCode));         Log.i("ActivityRecords", errorCode + ": " + errorMsg);     } });

5. If the user moves for a long time , Every adjacent 10 minute （ Less than 10 minute ） Need to call ActivityRecordsController Of continueActivityRecord The interface continues to apply for background preservation 10 minute ;

//  Please note that this by Activity object ActivityRecordsController activityRecordsController = HuaweiHiHealth.getActivityRecordsController(this); //  call continueActivityRecord Method to apply for permission to run in the background for the specified motion record , The parameter for ActivityRecord Of ID character string  Task<Void> endTask = activityRecordsController.continueActivityRecord("MyBeginActivityRecordId");endTask.addOnSuccessListener(new OnSuccessListener<Void>() {    @Override    public void onSuccess(Void aVoid) {        Log.i("ActivityRecords", "continue backgroundActivityRecord was successful!");    }}).addOnFailureListener(new OnFailureListener() {    @Override    public void onFailure(Exception e) {        Log.i("ActivityRecords", "continue backgroundActivityRecord error");    }});

6. When the user's movement ends , call ActivityRecordsController Of endActivityRecord The interface stops the motion recording , At the same time, cancel the application background preservation ;

//  Please note that this by Activity object final ActivityRecordsController activityRecordsController = HuaweiHiHealth.getActivityRecordsController(this);//  call endActivityRecord Interface stops motion recording , The parameter for ActivityRecord Of ID String or null//  The parameter for ID When the string , Stop the current application assignment ID Movement record of //  The parameter for null when , Stop all current unstopped motion records of the application Task<List<ActivityRecord>> endTask = activityRecordsController.endActivityRecord("MyBeginActivityRecordId");endTask.addOnSuccessListener(new OnSuccessListener<List<ActivityRecord>>() {    @Override    public void onSuccess(List<ActivityRecord> activityRecords) {        Log.i("ActivityRecords","MyActivityRecord End success");        //  Return the list of motion records that have stopped successfully         if (activityRecords.size() > 0) {            for (ActivityRecord activityRecord : activityRecords) {                DateFormat dateFormat = DateFormat.getDateInstance();                DateFormat timeFormat = DateFormat.getTimeInstance();                Log.i("ActivityRecords", "Returned for ActivityRecord: " + activityRecord.getName() + "\n\tActivityRecord Identifier is "                    + activityRecord.getId() + "\n\tActivityRecord created by app is " + activityRecord.getPackageName()                    + "\n\tDescription: " + activityRecord.getDesc() + "\n\tStart: "                    + dateFormat.format(activityRecord.getStartTime(TimeUnit.MILLISECONDS)) + " "                    + timeFormat.format(activityRecord.getStartTime(TimeUnit.MILLISECONDS)) + "\n\tEnd: "                    + dateFormat.format(activityRecord.getEndTime(TimeUnit.MILLISECONDS)) + " "                    + timeFormat.format(activityRecord.getEndTime(TimeUnit.MILLISECONDS)) + "\n\tActivity:"                    + activityRecord.getActivityType());            }        } else {            //  Failed to stop and return successfully null            Log.i("ActivityRecords","MyActivityRecord End response is null");        }    }}).addOnFailureListener(new OnFailureListener() {    @Override    public void onFailure(Exception e) {        String errorCode = e.getMessage();        String errorMsg = HiHealthStatusCodes.getStatusCodeMessage(Integer.parseInt(errorCode));        Log.i("ActivityRecords",errorCode + ": " + errorMsg);    }});

It should be noted that , Because the end and side backstage are kept alive API Belongs to sensitive permission , The access of sports applications requires manual review , Ensure data security 、 Only process compliance can be put on the shelves .
