android广播接收器和服务获取通知

Question

hi i have used the following code in receiver class

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.e("the time is right","yay!");
        Intent i = new Intent(context, AlarmServie.class);
        context.startService(i);
    }
 }

here i the code which i used in service class

public class AlarmServie extends Service {
    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Log.e("onStart:","came" );
     /*  NotificationManager notifyman = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        Intent main_activity = new Intent(this.getApplicationContext(), MainActivity.class);
        PendingIntent o = PendingIntent.getActivity(this, 0, main_activity, 0);

        /*Notification noti = new Notification.Builder(this)
                .setContentTitle("Reminder to Pill")
                .setContentText("Click for info")
                .setAutoCancel(true)
                .setContentIntent(o)
                .build();*/
        NotificationManager nm = (NotificationManager) this.getApplicationContext().getSystemService(NOTIFICATION_SERVICE);
        Intent in = new Intent(this.getApplicationContext(), MainActivity.class);
        PendingIntent pending = PendingIntent.getactivity(this, 0, in, 0);
        NotificationCompat.Builder mBuilder =new NotificationCompat.Builder(AlarmServie.this);
        mBuilder.setContentTitle("Pill Reminder");
        mBuilder.setContentText("CLick here to View");
        //mBuilder.setSound(sound);

        TaskStackBuilder ts=TaskStackBuilder.create(this);
        ts.addParentStack(MainActivity.class);
        nm.notify(9999,mBuilder.build());

    }}

i created this code to get notification.when i run the app the receiver class is triggered but it is not moving to service class to invoke notification.can anyone say whats wrong in the code or say me how to get notification using broadcast receiver and service in a detailed tutorial

here is the manifest file and say me where to put the code exactly

<uses-permission android:name="android.permission.VIBRATE"/>
    <uses-permission android:name="android.permission.WAKE_LOCK"/>
    <uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>


    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">

                <category android:name="android.intent.category.LAUNCHER" />



            </intent-filter>
        </activity>
        <receiver android:name=".AlarmReceiver"></receiver>
        <activity android:name=".Set"></activity><!-- ATTENTION: This was auto-generated to add Google Play services to your project for

        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
    </application>

</manifest>

please explain in detail what the problem in code.please tell exactly where to put the service tag

Answer 1

You must declare service in manifest also. Intent to start service is sent to system then system tries to find right application component to handle this particular intent using information passed in manifest files.

It should be enough, but I'm not sure if you put service in the default package.

<application>
    ....
    <service android:name=".AlarmServie"/>
    ....
</application>

Answer 2

Your Manifest should look something like this

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />



        </intent-filter>
    </activity>

    //here is your service
     <service android:name=".AlarmServie" android:enabled="true"/>

    <receiver android:name=".AlarmReceiver"></receiver>
    <activity android:name=".Set"></activity><!-- ATTENTION: This was auto-generated to add Google Play services to your project for

    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
</application>
