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 ：
- 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 .
- This problem can be solved by integrating Huawei sports health services , 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
- Please refer to the development preparation completion Application Health Kit service , Check the data permission required for the product and integrate SDK.
- To call the background keep alive function, you need to apply for the permission to read the motion records , Then obtain the user authorization to complete the permission application .
- 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 ;
- 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 beginActivityRecord
Task<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);
}
});

- 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");
}

- 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 .
