我正在开发一款Android应用,它使用BroadcastReceiver在手机启动时做一些工作。在运行Android 4.4.4 KitKat的Nexus 5上,它工作正常,但是我的一个朋友在运行Android 2.3.6的手机中对它进行了测试,但它没有用。我的代码如下:
public class PowerConnectionReceiver extends BroadcastReceiver {
private static final int NOTIFICATION_ID = 1;
@Override
public void onReceive(Context context, Intent intent) {
NotificationCompat.Builder notifBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("My app")
.setContentText("My notification...")
.setTicker("My awesome notification");
NotificationManager notifManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notifManager.notify(NOTIFICATION_ID, notifBuilder.build());
}
}
在BroadcastReceiver中,我只是显示通知。然后,我在AndroidManifest.xml上注册BroadcastReceiver:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
...More code...
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
...More code...
<receiver
android:name=".activities.PowerConnectionReceiver"
android:enabled="true" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
... More code...
</application>
如何让我的应用在Android 2.x上运行?

答案 0 :(得分:0)
尝试在接收器外部设置权限:
....
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"></uses-permission>
<application
....
将安装位置设置为internalOnly:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
...
android:installLocation="internalOnly"
>
最后,尝试修改接收器代码,如果以上仍然不起作用:
<receiver android:name=".activities.PowerConnectionReceiver"
android:enabled="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
</intent-filter>
</receiver>
