问题描述

我升级到最新的SDK和所有的突然我的小部件在启动时没有与此消息后回来的Widget开发

I got back to the widget development after upgrading to the latest SDK and all of the sudden my widget is failing on startup with this message:

ERROR/AndroidRuntime(5296): java.lang.RuntimeException:
Unable to start receiver topjob.widget.SearchWidget:
java.lang.SecurityException: Permission Denial:
attempt to change component state from pid=5296, uid=10057, package uid=10048

下面是code两线，其中发生异常：

Here's two lines of code where exception occurs:

@Override
public void onEnabled(Context context) {
    PackageManager pm = context.getPackageManager();
    pm.setComponentEnabledSetting(new ComponentName("topjob",
            ".widget.SearchWidgetBroadcastReceiver"),
            PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
            PackageManager.DONT_KILL_APP);
    startAlarm(context, UPDATE_RATE_SEC);
}

所以在code以上 startAlarm（），因为 pm.setComponentEnabledSetting永远不会执行（）抛出在SecurityException异常

so in the code above startAlarm() is never executed since pm.setComponentEnabledSetting() throws the SecurityException

我失去了我的清单任何安全设置？目前，我有：

Am I missing any security settings in my manifest? Currently I have:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

我制定 SDK诉1.5 并用它做工精细

P.S。它发生在手机上和模拟器

P.S. It happens on the phone and the emulator

推荐答案

确定 - 这是没有真正回答，而是一种解决方法。如果有人想介入，并提供解答或解释上应如何做我很乐意接受的。
反正 - 我把它从 COMPONENT_ENABLED_STATE_ENABLED 更改 newState 标志 PackageManager.COMPONENT_ENABLED_STATE_DEFAULT 。由于我的广播接收器已在清单中启用状态只是正常工作

OK - this is not really answer but rather a workaround. If someone wants to step in and provide answer or explanations on how this should be done I would gladly accept that.Anyway - I got it working by changing newState flag from COMPONENT_ENABLED_STATE_ENABLED to PackageManager.COMPONENT_ENABLED_STATE_DEFAULT. Since my broadcast receiver has enabled state in the manifest it works just fine
