Question

单击按钮后，我必须在10 sec之后安排在设备上调用已安装的测试项目。为此，我创建了一个AlarmReceiver和我的TaskService，它实际上正在调用测试项目。

运行应用程序后，单击该按钮后没有任何反应。我不知道出了什么问题，但服务即使在10秒后也无法完成工作。

以下是我正在尝试的代码。 Activity类：

// Create an anonymous implementation of OnClickListener
private OnClickListener HTListener = new OnClickListener() {
    public void onClick(View v) {
        btnStartSchedule(v);
    } 
};


public void btnStartSchedule(View v) {
    try {
        AlarmManager alarms = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);

        Intent intent = new Intent(getApplicationContext(), AlarmReceiver.class);
        intent.putExtra(AlarmReceiver.ACTION_ALARM, AlarmReceiver.ACTION_ALARM);


        final PendingIntent pIntent = PendingIntent.getBroadcast(this, 1234567, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        alarms.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 10000, pIntent);

        Toast.makeText(ScrapeActivity.this, "Alarm Started", Toast.LENGTH_LONG).show();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

AlarmReceiver类：

public class AlarmReceiver extends BroadcastReceiver {

public static String ACTION_ALARM = "com.alarmmanager.alarm";

 @Override
 public void onReceive(Context context, Intent intent) {

    Log.i("Alarm Receiver", "Entered");
    Toast.makeText(context, "Entered", Toast.LENGTH_SHORT).show();

    Bundle bundle = intent.getExtras();
    String action = bundle.getString(ACTION_ALARM);

    if (action.equals(ACTION_ALARM)) {
        Log.i("Alarm Receiver", "If loop");
        Intent inService = new Intent(context, LaunchService.class);
        context.startService(inService);
    } else {
        Log.i("Alarm Receiver", "Else loop");
        Toast.makeText(context, "Else loop", Toast.LENGTH_SHORT).show();
    }
 }

}

最后是LaunchService类：

public class LaunchService extends IntentService {

public LaunchService(String name) {
    super(name);
    // TODO Auto-generated constructor stub
}


@Override
protected void onHandleIntent(Intent intent) {
    Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("com.my.testproject");
    startActivity(LaunchIntent);
}

}

我还提到了清单文件中的接收者和服务：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.my.pb.activity"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/PB_APP"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.my.pb.activity.ScrapeActivity"
        android:label="@string/PB_APP" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver
        android:name=".AlarmReceiver"
        android:process=":remote" >
    </receiver>

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

我不明白这个问题是什么，因为Logcat中没有例外。当我点击按钮时，我只看到吐司留言Alarm Started。请帮忙。

您在Manifest处输入了一个拼写错误，您在那里声明了AlaramReceiver而不是.AlarmReceiver。

AlarmManager未运行服务
