Intermediate: Schedule Alarm in HMS Based Android App
Overview
In this article, I will create a Schedule Alarm android application in which I will integrate HMS Core kits such as Huawei ID, Crash and Analytics.
Huawei ID Service Introduction
Huawei ID login provides you with simple, secure, and quick sign-in and authorization functions. Instead of entering accounts and passwords and waiting for authentication, users can just tap the Sign in with HUAWEI ID button to quickly and securely sign in to your app with their HUAWEI IDs.
Prerequisite
1. Huawei Phone EMUI 3.0 or later.
2. Non-Huawei phones Android 4.4 or later (API level 19 or higher).
3. HMS Core APK 4.0.0.300 or later
4. Android Studio
5. AppGallery Account
App Gallery Integration process
- Sign In and Create or Choose a project on AppGallery Connect portal.
2. Navigate to Project settings and download the configuration file.
3. Navigate to General Information, and then provide Data Storage location.
App Development
- Create A New Project.
2. Configure Project Gradle.
buildscript {
repositories {
google()
jcenter()
maven { url 'http://developer.huawei.com/repo/' }
}
dependencies {
classpath 'com.android.tools.build:gradle:4.0.2'
classpath 'com.huawei.agconnect:agcp:1.3.1.300'
}
}
allprojects {
repositories {
google()
jcenter()
maven { url 'http://developer.huawei.com/repo/' }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}3. Configure App Gradle.
apply plugin: 'com.android.application'
apply plugin: 'com.huawei.agconnect'
android {
compileSdkVersion 30
buildToolsVersion "29.0.3"
defaultConfig {
applicationId "com.hms.alarmapp"
minSdkVersion 27
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.4.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
//HMS Kits
api 'com.huawei.hms:dynamicability:1.0.11.302'
implementation 'com.huawei.agconnect:agconnect-auth:1.4.1.300'
implementation 'com.huawei.hms:hwid:5.3.0.302'
implementation 'com.huawei.hms:ads-lite:13.4.30.307'
implementation 'com.huawei.agconnect:agconnect-remoteconfig:1.6.0.300'
implementation 'com.huawei.hms:hianalytics:5.0.3.300'
implementation 'com.huawei.agconnect:agconnect-crash:1.4.1.300'
}4. Configure AndroidManifest.xml.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.hms.alarmapp">
<uses-permission android:name="android.permission.WAKE_LOCK" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name=".MyAlarm"
android:enabled="true"
android:exported="true" />
</application>
</manifest>5. Create Activity class with XML UI.
MainActivity:
package com.hms.alarmapp;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TimePicker;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
import java.util.Calendar;
public class MainActivity extends AppCompatActivity {
TimePicker timePicker;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
timePicker = (TimePicker) findViewById(R.id.timePicker);
findViewById(R.id.buttonAlarm).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Calendar calendar = Calendar.getInstance();
if (android.os.Build.VERSION.SDK_INT >= 23) {
calendar.set(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH),
timePicker.getHour(), timePicker.getMinute(), 0);
} else {
calendar.set(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH),
timePicker.getCurrentHour(), timePicker.getCurrentMinute(), 0);
}
setAlarm(calendar.getTimeInMillis());
}
});
}
private void setAlarm(long time) {
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(this, MyAlarm.class);
PendingIntent pi = PendingIntent.getBroadcast(this, 0, i, 0);
am.setRepeating(AlarmManager.RTC, time, AlarmManager.INTERVAL_DAY, pi);
Toast.makeText(this, "Alarm is set", Toast.LENGTH_SHORT).show();
}
}Xml-
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp">
<LinearLayout
android:id="@+id/linearLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:orientation="vertical">
<TimePicker
android:id="@+id/timePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="@+id/buttonAlarm"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Set Alarm" />
</LinearLayout>
</RelativeLayout>App Build Result
Tips and Tricks
Identity Kit displays the HUAWEI ID registration or sign-in page first. The user can use the functions provided by Identity Kit only after signing in using a registered HUAWEI ID.
