我正在尝试在启动后立即设置警报接收器。因此,我有一个应该注册警报的OnBootReceiver。 onBootReceiver工作,它被调用,但不知何故它找不到我的AlarmReceiver类。
OnBootReceiver在启动后成功启动:
public class OnBootReceiver extends BroadcastReceiver {
private static final String TAG = "OnBootReceiver";
@Override
public void onReceive(Context context, Intent intent) {
Log.i(TAG, "called");
Intent i = new Intent(context, com.packagenames.AlarmReceiver.class);
PendingIntent pi = PendingIntent.getService(context, 0, i, 0);
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Calendar time = Calendar.getInstance();
time.setTimeInMillis(System.currentTimeMillis());
time.add(Calendar.SECOND, 30);
am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), time.getTimeInMillis(), pi);
}
}
正如您所看到的,它配置警报尝试调用com.packagenames.AlarmReceiver.class。该类存在且位于同一个包中:
public class AlarmReceiver extends BroadcastReceiver {
private static final String TAG = "AlarmReceiver";
@Override
public void onReceive(Context context, Intent intent) {
Log.i(TAG, "alarm received");
Intent i = new Intent(context, com.packagename.DataService.class);
i.putExtra("action", "process");
context.startService(i);
}
}
不幸的是,我收到以下错误:
02-03 09:22:25.344:W / ActivityManager(103):无法启动服务 意图{flg = 0x4 cmp = com.phonegap.packagename / .AlarmReceiver(有附加内容) }:未找到
Android Manifest看起来像这样
<application>
// activities etc
<receiver
android:name="com.phonegap.packagename.OnBootReceiver"
android:enabled="true"
android:exported="false"
android:label="OnBootReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<receiver
android:name="com.phonegap.packagename.AlarmReceiver"
android:enabled="true"
android:label="AlarmReceiver">
<intent-filter>
</intent-filter>
</receiver>
</application>
你知道错了吗?也许我忘记了什么?
由于
编辑:在清单中,我添加了
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
为了使OnBootReceiver工作。警报需要类似的东西吗?
答案 0 :(得分:1)
创建待定意图时,不应该使用getBroadcast而不是getService吗?
答案 1 :(得分:0)
如果你的应用程序没有安装在SD卡上,整个接收器的东西才有效。将其添加到清单文件中:
机器人:的installLocation = “internalOnly”
