安卓:FileProvider抛出:IllegalArgumentException无法找到配置的根包含/数据/数据/
问题描述:
我试图将图像保存到内部存储和我面对:安卓:FileProvider抛出:IllegalArgumentException无法找到配置的根包含/数据/数据/
java.lang.IllegalArgumentException: Failed to find configured root that contains /data/data/com.example.example/app_images/f9732a4a-a22e-4b62-b9b3-e546c8edc93c.jpg.
at android.support.v4.content.FileProvider$SimplePathStrategy.getUriForFile(FileProvider.java:711)
at android.support.v4.content.FileProvider.getUriForFile(FileProvider.java:400)
at com.example.example.fragments.PhotosFragment.createImageFile(PhotosFragment.java:182)
at com.example.example.fragments.PhotosFragment.dispatchTakePictureIntent(PhotosFragment.java:191)
Java代码:
private File createImageFile() throws IOException {
ContextWrapper cw = new ContextWrapper(getActivity());
// path to /data/data/yourapp/app_data/imageDir
File directory = cw.getDir("images", Context.MODE_PRIVATE);
if(!directory.exists())
directory.mkdirs();
// Create imageDir
File mypath = new File(directory,UUID.randomUUID().toString() +".jpg");
if(!mypath.exists())
mypath.createNewFile();
Uri photoURI = FileProvider.getUriForFile(getActivity(), BuildConfig.APPLICATION_ID + ".provider",mypath);
return mypath;
}
private void dispatchTakePictureIntent() throws IOException {
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
return;
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(getActivity(), BuildConfig.APPLICATION_ID + ".provider",createImageFile());
mCurrentPhotoPath = "file:" + photoFile.getAbsolutePath();
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
}
我的路径代码:
<files-path name="my_images" path="app_images/"/>
我的清单代码:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.example.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths"/>
</provider>
对此有何线索?在私有目录cw.getDir("images", Context.MODE_PRIVATE);
描述另一个可用sollution'FileProvider'不能从任意位置,如()''通过创建GETDIR自定义目录服务。可以将文件存储在更常见的位置(如Stanislav所建议的),为[我的StreamProvider](https://github.com/commonsguy/cwac-provider)写一个可以从那里启动的扩展,或者创建自己的文件'ContentProvider'。 – CommonsWare
