嘿大家当我将我的应用程序安装到模拟器时我得到这个:

错误/AndroidRuntime(465): java.lang.RuntimeException: 无法启动接收器 com.myPackage.Widget.MYWidget: java.lang.SecurityException: 不允许启动服务 Intent { cmp=com.myPackage/.Widget. MYWidget$MyWidgetService } 未经许可 android.permission.BIND_REMOTEVIEWS

这是我的清单中的代码,

    <!-- Broadcast Receiver that will process AppWidget updates -->
    <receiver android:name=".Widget.MYWidget" android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />

            <!--Broadcast Receiver that will also process our self created action -->
            <action android:name="com.temp.package.Widget.MYWidget.ACTION_WIDGET_LEFT_RECEIVER" />


            <action android:name="com.temp.package.Widget.MYWidget.ACTION_WIDGET_PROGRESSBAR_RECEIVER" />
        </intent-filter>
        <meta-data android:name="android.appwidget.provider"
            android:resource="@xml/mywidget_widget_provider" />

    </receiver>
    <service android:name=".Widget.MYWidget$MyWidgetService"
        android:permission="android.permission.BIND_REMOTEVIEWS"
        android:exported="true"  />
        <uses-permission
    android:name="android.permission.BIND_REMOTEVIEWS"></uses-permission>

这是我的代码

public class MyWidget extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

    Intent svcIntent = new Intent(context, MyWidgetService.class);

    //svcIntent.setData(Uri.parse(svcIntent.toUri(Intent.URI_INTENT_SCHEME)));
    context.startService(svcIntent);
}

public static class MyWidgetService extends Service
{
    @Override
    public void onStart(Intent intent, int startId)
    {
        super.onStart(intent, startId);
        // Update the widget
        RemoteViews remoteView = buildRemoteView(this);

        // Push update to homescreen
        pushUpdate(remoteView);

        // No more updates so stop the service and free resources
        stopSelf();
    }

    public RemoteViews buildRemoteView(Context context)
    {
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);

        //do stuff


        return remoteViews;
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        int oldOrientation = this.getResources().getConfiguration().orientation;

        if(newConfig.orientation != oldOrientation)
        {
            // Update the widget
            RemoteViews remoteView = buildRemoteView(this);

            // Push update to homescreen
            pushUpdate(remoteView);
        }
    }

    private void pushUpdate(RemoteViews remoteView)
    {
        ComponentName myWidget = new ComponentName(this, MyWidget.class);
        AppWidgetManager manager = AppWidgetManager.getInstance(this);
        manager.updateAppWidget(myWidget, remoteView);
    }

    @Override
    public IBinder onBind(Intent arg0)
    {
        // TODO Auto-generated method stub
        return null;
    }
}

hey all when installing my app to the emulator I get this:

ERROR/AndroidRuntime(465): java.lang.RuntimeException: Unable to start receiver com.myPackage.Widget.MYWidget: java.lang.SecurityException: Not allowed to start service Intent { cmp=com.myPackage/.Widget.MYWidget$MyWidgetService } without permission android.permission.BIND_REMOTEVIEWS

here is the code from my manifest

    <!-- Broadcast Receiver that will process AppWidget updates -->
    <receiver android:name=".Widget.MYWidget" android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />

            <!--Broadcast Receiver that will also process our self created action -->
            <action android:name="com.temp.package.Widget.MYWidget.ACTION_WIDGET_LEFT_RECEIVER" />


            <action android:name="com.temp.package.Widget.MYWidget.ACTION_WIDGET_PROGRESSBAR_RECEIVER" />
        </intent-filter>
        <meta-data android:name="android.appwidget.provider"
            android:resource="@xml/mywidget_widget_provider" />

    </receiver>
    <service android:name=".Widget.MYWidget$MyWidgetService"
        android:permission="android.permission.BIND_REMOTEVIEWS"
        android:exported="true"  />
        <uses-permission
    android:name="android.permission.BIND_REMOTEVIEWS"></uses-permission>

this is my code

public class MyWidget extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

    Intent svcIntent = new Intent(context, MyWidgetService.class);

    //svcIntent.setData(Uri.parse(svcIntent.toUri(Intent.URI_INTENT_SCHEME)));
    context.startService(svcIntent);
}

public static class MyWidgetService extends Service
{
    @Override
    public void onStart(Intent intent, int startId)
    {
        super.onStart(intent, startId);
        // Update the widget
        RemoteViews remoteView = buildRemoteView(this);

        // Push update to homescreen
        pushUpdate(remoteView);

        // No more updates so stop the service and free resources
        stopSelf();
    }

    public RemoteViews buildRemoteView(Context context)
    {
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);

        //do stuff


        return remoteViews;
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        int oldOrientation = this.getResources().getConfiguration().orientation;

        if(newConfig.orientation != oldOrientation)
        {
            // Update the widget
            RemoteViews remoteView = buildRemoteView(this);

            // Push update to homescreen
            pushUpdate(remoteView);
        }
    }

    private void pushUpdate(RemoteViews remoteView)
    {
        ComponentName myWidget = new ComponentName(this, MyWidget.class);
        AppWidgetManager manager = AppWidgetManager.getInstance(this);
        manager.updateAppWidget(myWidget, remoteView);
    }

    @Override
    public IBinder onBind(Intent arg0)
    {
        // TODO Auto-generated method stub
        return null;
    }
}

删除:

    android:permission="android.permission.BIND_REMOTEVIEWS"
    android:exported="true"

从您的 元素中 ,因为这里都不需要。这应该可以解决你的问题。

Get rid of:

    android:permission="android.permission.BIND_REMOTEVIEWS"
    android:exported="true"

from your <service> element, as neither are needed here. This should clear up your problem.

它几乎可以工作,当我添加小部件时我处于垂直模式。当方向发生变化时(水平方向) - 我认为应该调用 onConfigurationChanged 但事实并非如此 - 因此我的小部件在之后无法工作

为此,您需要提及要处理的 android:configChanges 参数你的。
如果您正在处理 ICS 代码,请不要将“screenSize”元素与“keyboardHidden|screenSize”等其他参数一起放置在那里
希望这会对您有所帮助。

我提到这一点只是为了活动......我错误地理解了你的问题。
感谢您的更新。

it's almost working, I'm in vertical mode when I add the Widget. when on orientation change happens(To Horizontal) - I thought that onConfigurationChanged should be called but it is not- thus my widget is not working after

For this you need to mention the android:configChanges parameter for which you want to handle your on.
Please not if you working on ICS code you need to put 'screenSize' element also there with other parameters like 'keyboardHidden|screenSize'
Hope this will help you.

I mentioned this for activity only...I took your question wrongly.
Thanks for update.
