Due to personal issues, this project is no longer maintained. You can still use it. Also you can see this awesome projects:
- Pangliang with his library I started with mine
- Gadgetbridge I got all the activities part and some command ideas from them
Sweet and simple Android implementation to control some aspects of your Xiaomi Mi Band.
- Connect and Disconnect
- Start vibration (with pre defined and customs values)
- Change led's colors (with pre defined and customs values)
- Get battery info
- Sync with your Mi Band (steps, slept hours, etc)
- Real time step counter
Mi-Band is ultra simple to use! just follow this 1 step:
-
In your app's dependencies add the library:
dependencies { compile 'com.betomaluje.miband:app:1.0.4' }
that's it! You're ready!
Note: this is thanks to the new Android Studio that uses jCenter instead of MavenCentral. To see this, you can open your main build.gradle file, and under the repositories you should see jcenter(). If not, add this as a repository
allprojects {
repositories {
mavenCentral()
maven {
url 'https://dl.bintray.com/betomaluje/maven/'
}
}
}
Now, to start testing you can use this library in activities, fragments an even services! As an alternative you can use the pre defined MiBandService
-
Define your Mi Band variable (globaly or localy, it doesn't matter because it's a Singleton) and pass it the current Context variable:
MiBand miBand = MiBand.getInstance(MyActivity.this); -
Now, to toggle connection you can use
if (!miBand.isConnected()) { miBand.connect(new ActionCallback() { @Override public void onSuccess(Object data) { Log.d(TAG, "Connected with Mi Band!"); //show SnackBar/Toast or something } @Override public void onFail(int errorCode, String msg) { Log.d(TAG, "Connection failed: " + msg); } }); } else { miBand.disconnect(); }
Now the fun part: sending commands to your band.
For vibration you can use the following methods:
//to vibrate using the default band color
miBand.startVibration(VibrationMode.VIBRATION_WITH_LED);
//to vibrate until you manually stop it
miBand.startVibration(VibrationMode.VIBRATION_UNTIL_CALL_STOP);
//to vibrate without the led
miBand.startVibration(VibrationMode.VIBRATION_WITHOUT_LED);
//to stop vibration
miBand.stopVibration();
Also there's a custom vibration method
miBand.customVibration(times, on_time, off_time);
where times is an int value to determine how many times will vibrate(I recommend to use between 1-3 times only)
and on_time is the time in milliseconds that each vibration will be On (not more than 500 milliseconds)
and off_time is the pause between each consecutive vibration
To change the LED color, you can use
miBand.setLedColor(color);
where color is an int value representing the color you want
For convenience, there's a ColorPickerDialog class to help choose the int value of a color
new ColorPickerDialog(MyActivity.this, 255, new ColorPickerDialog.OnColorSelectedListener() {
@Override
public void onColorSelected(int rgb) {
Log.i(TAG, "selected color: " + rgb);
miBand.setLedColor(rgb);
}
}).show();
or you can use
miBand.setLedColor(flash_time, color, pause_time);
where flash_time is an int value to determine how many times will the led flash (I recommend using 1-3 values only)
and color is the int value of the color
and pause_time is the pause in milliseconds between each flash
To get the battery information just use
miBand.getBatteryInfo(new ActionCallback() {
@Override
public void onSuccess(final Object data) {
BatteryInfo battery = (BatteryInfo) data;
//get the cycle count, the level and other information
Log.e(TAG, "Battery: " + battery.toString());
}
@Override
public void onFail(int errorCode, String msg) {
Log.e(TAG, "Fail battery: " + msg);
}
});
To sync data with yor Mi Band use
miBand.startListeningSync();
this will start the sync process. Also you can
if (miBand.isSyncNotification())
miBand.stopListeningSync();
After you are finished syncing with the band, you can access the information using
Calendar before = Calendar.getInstance();
//7 days before
before.add(Calendar.DAY_OF_WEEK, -7);
long temp = before.getTimeInMillis() / 1000;
before.setTimeInMillis(temp);
Calendar today = Calendar.getInstance();
//now
today.setTimeInMillis(System.currentTimeMillis() / 1000);
//use DateUtils to display the time in the format "yyyy-MM-dd HH:mm:ss"
Log.i(TAG, "data from " + DateUtils.convertString(before) + " to " + DateUtils.convertString(today));
//all our data is stored in ActivitySQLite as ActivityData objects
ArrayList<ActivityData> allActivities = ActivitySQLite.getInstance(ActivitiesChartActivity.this)
.getActivitySamples((int) before.getTimeInMillis(), (int) today.getTimeInMillis());
to get the sleeping data use
ActivitySQLite.getInstance(MySleepActivity.this).getSleepSamples(int timestamp_from, int timestamp_to)
and to get the activity data use
ActivitySQLite.getInstance(MyActivitiesActivity.this).getActivitySamples(int timestamp_from, int timestamp_to)
to get ALL the data use
ActivitySQLite.getInstance(MyAllActivity.this).getAllActivitiesSamples(int timestamp_from, int timestamp_to)
Calendar before = Calendar.getInstance();
//7 days before
before.add(Calendar.DAY_OF_WEEK, -7);
long temp = before.getTimeInMillis() / 1000;
before.setTimeInMillis(temp);
Calendar today = Calendar.getInstance();
//now
today.setTimeInMillis(System.currentTimeMillis() / 1000);
//use DateUtils to display the time in the format "yyyy-MM-dd HH:mm:ss"
Log.i(TAG, "data from " + DateUtils.convertString(before) + " to " + DateUtils.convertString(today));
//all our data is stored in ActivitySQLite as ActivityData objects
ArrayList<ActivityData> allActivities = ActivitySQLite.getInstance(ActivitiesChartActivity.this)
.getActivitySamples((int) before.getTimeInMillis(), (int) today.getTimeInMillis());
float movement_divisor = 180.0f;
float value;
String dateString = "";
for (ActivityData ad : allActivities) {
Calendar date = Calendar.getInstance();
date.setTimeInMillis(ad.getTimestamp() * 1000L);
dateString = DateUtils.convertString(date);
Log.i(TAG, "date " + dateString);
Log.i(TAG, "steps " + ad.getSteps());
short movement = ad.getIntensity();
byte steps = ad.getSteps();
if (steps != 0) {
// I'm not sure using steps for this is actually a good idea
movement = steps;
}
//the value
value = ((float) movement) / movement_divisor;
}
Calendar before = Calendar.getInstance();
//7 days before
before.add(Calendar.DAY_OF_WEEK, -7);
long temp = before.getTimeInMillis() / 1000;
before.setTimeInMillis(temp);
Calendar today = Calendar.getInstance();
//now
today.setTimeInMillis(System.currentTimeMillis() / 1000);
//use DateUtils to display the time in the format "yyyy-MM-dd HH:mm:ss"
Log.i(TAG, "data from " + DateUtils.convertString(before) + " to " + DateUtils.convertString(today));
ArrayList<ActivityData> allActivities = ActivitySQLite.getInstance(SleepChartActivity.this)
.getSleepSamples((int) before.getTimeInMillis(), (int) today.getTimeInMillis());
float movement_divisor = 180.0f;
float value;
String dateString = "";
for (ActivityData ad : allActivities) {
Calendar date = Calendar.getInstance();
date.setTimeInMillis(ad.getTimestamp() * 1000L);
dateString = DateUtils.convertString(date);
Log.i(TAG, "date " + dateString);
Log.i(TAG, "steps " + ad.getSteps());
value = ((float) ad.getIntensity()) / movement_divisor;
switch (ad.getType()) {
case ActivityData.TYPE_DEEP_SLEEP:
//DEEP SLEEP TYPE. Only here we need to adjust the value
value += ActivityData.Y_VALUE_DEEP_SLEEP;
doSomethingWithDeepSleep(value);
break;
case ActivityData.TYPE_LIGHT_SLEEP:
//LIGHT SLEEP TYPE
doSomethingWithLightSleep(value);
break;
default:
//UNKNOWN TYPE
doSomethingWithUnknownSleep(value);
break;
}
}
Also you can track the "Sleep comparison"
private void refreshSleepAmounts(List<ActivityData> samples) {
ActivityAnalysis analysis = new ActivityAnalysis();
ActivityAmounts amounts = analysis.calculateActivityAmounts(samples);
float hoursOfSleep = amounts.getTotalSeconds() / (float) (60 * 60);
Log.i(TAG, "hoursOfSleep " + hoursOfSleep + " h");
for (ActivityAmount amount : amounts.getAmounts()) {
Log.i(TAG, "name " + amount.getName());
Log.i(TAG, "total seconds " + amount.getTotalSeconds());
Log.i(TAG, "kind " + amount.getActivityKind());
}
}
The first time you connect with your Mi Band please be patient. It takes around 45 seconds. After this time, if you can't connect to it, try the following
- Try disconnecting and again connecting to Bluetooth
- Uninstall and install again your app
If you also have the Mi Fit app installed, you may lose some information on the syncing because Mi Fit and your app will be "fighting" to sync the Mi Band data. Once the Mi Band data is synced, it will be "deleted" from the band and lost forever.
Also the pairing process may ocurr several times each time you switch from apps because you will lose th pairing info from each app.
Nevertheless you can still send commands to the Mi Band if you are using both apps. It's not mandatory to uninstall Mi Fit to use this library.
