嘿,当我将我的应用程序安装到模拟器时,我得到了这个:
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}没有权限android.permission.BIND_REMOTEVIEWS
这是我清单中的代码
<!-- 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"

</receiver>

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;
}
}

摆脱:
android:permission="android.permission.BIND_REMOTEVIEWS"
android:exported="true"
来自<service>
元素的,因为这里都不需要。这应该可以解决你的问题。

它几乎正常工作,当我添加Widget时,我处于垂直模式。当方向改变发生时(To Horizontal) - 我认为应该调用onConfigurationChanged但是它不是 - 因此我的小部件在之后无效
为此你需要提到你想要处理你的android:configChanges参数。 请不要,如果您正在使用ICS代码,您需要将'screenSize'元素与其他参数放在一起,例如'keyboardHidden | screenSize' 希望这会对你有所帮助。
我之所以提到这只是为了活动......我错误地提出了你的问题。 感谢您的更新。
