我知道这个问题已经问过，但我真的很惊讶，如此努力之后。我还没有启用的Andr​​oid模拟器的工作报警。我已经尝试了所有$ C $的CS这个论坛，但徒劳无功。即使我下载一个示例code仍然没有奏效。请大家帮我，大家好我送你我的所有code。谁能告诉我在Android模拟器做响铃警告？如果是的话那么是什么问题，我的code？我测试了同样的code的API 4级和10这两个没有工作。即使我创建2个不同的项目，但徒劳无功。

解决方案

我也得到同样的问题。但我安装我的应用程序在移动则警钟正在发挥作用。

后来我才知道警铃不工作的模拟器。因此，没有必要担心这一点。你必须尝试您的手机上。它的工作的罚款。

I know this question has asked before, but I am really surprised, after trying so hard. I have not enabled to work alarm on android emulator. I have tried all codes of this forum but in vain. Even I download a sample code still it did not work. please help me guys I am sending you my all code. Can anyone tell me "do alarm bell rings on android emulator"? If yes then what is problem in my code? I tested same code for API level 4 and 10. Both did not work. Even I create 2 different projects but in vain.

AndroidAlarmService:

package com.exercise.AndroidAlarmService; import java.util.Calendar; import android.app.Activity; import android.app.AlarmManager; import android.app.PendingIntent; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.Toast; public class AndroidAlarmService extends Activity { private PendingIntent pendingIntent; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button buttonStart = (Button)findViewById(R.id.startalarm); Button buttonCancel = (Button)findViewById(R.id.cancelalarm); buttonStart.setOnClickListener(new Button.OnClickListener(){ public void onClick(View arg0) { // TODO Auto-generated method stub Intent myIntent = new Intent(AndroidAlarmService.this, MyAlarmService.class); pendingIntent = PendingIntent.getService(AndroidAlarmService.this, 0, myIntent, 0); AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.add(Calendar.SECOND, 10); alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent); Toast.makeText(AndroidAlarmService.this, "Start Alarm", Toast.LENGTH_LONG).show(); }}); buttonCancel.setOnClickListener(new Button.OnClickListener(){ public void onClick(View arg0) { // TODO Auto-generated method stub AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE); alarmManager.cancel(pendingIntent); // Tell the user about what we did. Toast.makeText(AndroidAlarmService.this, "Cancel!", Toast.LENGTH_LONG).show(); }}); } }

MyAlarmService:

package com.exercise.AndroidAlarmService; import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.widget.Toast; public class MyAlarmService extends Service { @Override public void onCreate() { // TODO Auto-generated method stub Toast.makeText(this, "MyAlarmService.onCreate()", Toast.LENGTH_LONG).show(); } @Override public IBinder onBind(Intent intent) { // TODO Auto-generated method stub Toast.makeText(this, "MyAlarmService.onBind()", Toast.LENGTH_LONG).show(); return null; } @Override public void onDestroy() { // TODO Auto-generated method stub super.onDestroy(); Toast.makeText(this, "MyAlarmService.onDestroy()", Toast.LENGTH_LONG).show(); } @Override public void onStart(Intent intent, int startId) { // TODO Auto-generated method stub super.onStart(intent, startId); Toast.makeText(this, "MyAlarmService.onStart()", Toast.LENGTH_LONG).show(); } @Override public boolean onUnbind(Intent intent) { // TODO Auto-generated method stub Toast.makeText(this, "MyAlarmService.onUnbind()", Toast.LENGTH_LONG).show(); return super.onUnbind(intent); } }

Layout:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="schemas.android/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <Button android:id="@+id/startalarm" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Start" /> <Button android:id="@+id/cancelalarm" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Cancel" /> </LinearLayout>

Android manifest:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="schemas.android/apk/res/android" package="com.exercise.AndroidAlarmService" android:versionCode="1" android:versionName="1.0"> <uses-sdk android:minSdkVersion="4" /> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".AndroidAlarmService" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <service android:name=".MyAlarmService" /> </application> </manifest>

解决方案

I was also getting same problem. But I installed my application on mobile then the alarm bell was working.

Then I came to know alarm bell is not working on emulator. So no need to worry about this. You have to try on your mobile. Its working fine.
