我正在开发一个小部件应用程序,我的问题是运行应用程序时出现以下消息:未找到Launcher活动!,启动只会同步设备上的应用程序包!
这是代码:
Android Manifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.pack"
android:versionCode="1"

</application>
</manifest>
Meteowidget.java
public class MeteoWidget extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
// Create an Intent to launch TabsMeteoActivity
Intent intent = new Intent(context, TabsMeteoActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener
// to the widget
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.main);
views.setOnClickPendingIntent(R.id.Layout_widget, pendingIntent);
// Tell the AppWidgetManager to perform an update on the current app widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}

答案 0 :(得分:0)
您应该宣传一个Activity可以发布以消除此消息。
您可以通过将以下内容添加到您的某个活动(将其放在活动代码中)来执行此操作:
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
