android – FileProvider – 名称不能为空

我在我的清单中有以下FileProvider:

<provider android:name="android.support.v4.content.FileProvider" android:authorities="com.android.provider.DataSharing-1" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/paths"/> </provider> 

我在应用程序启动时遇到以下exception:

  java.lang.RuntimeException: Unable to get provider android.support.v4.content.FileProvider: java.lang.IllegalArgumentException: Name must not be empty at android.app.ActivityThread.installProvider(ActivityThread.java:4793) at android.app.ActivityThread.installContentProviders(ActivityThread.java:4385) at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4325) at android.app.ActivityThread.access$1500(ActivityThread.java:135) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1256) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:136) at android.app.ActivityThread.main(ActivityThread.java:5017) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:779) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:595) at dalvik.system.NativeStart.main(Native Method) Caused by: java.lang.IllegalArgumentException: Name must not be empty at android.support.v4.content.FileProvider$SimplePathStrategy.addRoot(FileProvider.java:644) at android.support.v4.content.FileProvider.parsePathStrategy(FileProvider.java:587) at android.support.v4.content.FileProvider.getPathStrategy(FileProvider.java:534) at android.support.v4.content.FileProvider.attachInfo(FileProvider.java:352) at android.app.ActivityThread.installProvider(ActivityThread.java:4790) ... 

我如何解决这个问题? 我在哪里错过指定一个名字?

编辑:

RES / XML / paths.xml

 <paths xmlns:android="http://schemas.android.com/apk/res/android"> <files-path android:name="my_images" android:path="images/"/> </paths>

paths.xml文件中的属性中删除android:前缀。 它应该看起来像:

 <paths xmlns:android="http://schemas.android.com/apk/res/android"> <files-path name="my_images" path="images/"/> </paths> 

(你也可以摆脱xmlns:android位,因为它没有被使用,虽然我已经在我的 ,也许是因为Eclipse在创build文件时把它放在那里…)
