NPE when using ImagePicker 1.2.2

[songpr]

I have follow you guide and install ImagePicker on my project and compile successfully.

But it have NPE below.

java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.res.XmlResourceParser android.content.pm.ProviderInfo.loadXmlMetaData(android.content.pm.PackageManager, java.lang.String)' on a null object reference at android.support.v4.content.FileProvider.parsePathStrategy(FileProvider.java:591) at android.support.v4.content.FileProvider.getPathStrategy(FileProvider.java:565) at android.support.v4.content.FileProvider.getUriForFile(FileProvider.java:403) at com.mvc.imagepicker.ImagePicker.getPickImageIntent(ImagePicker.java:219) at com.mvc.imagepicker.ImagePicker.startChooser(ImagePicker.java:189) at com.mvc.imagepicker.ImagePicker.pickImage(ImagePicker.java:180) at com.mvc.imagepicker.ImagePicker.pickImage(ImagePicker.java:79) at com.todayfortomorrow.dumex.childinfo.ChildInfoActivity$5.onClick(ChildInfoActivity.java:364) at android.view.View.performClick(View.java:5181) at android.view.View$PerformClick.run(View.java:20887) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:145) at android.app.ActivityThread.main(ActivityThread.java:5942) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1400) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1195)

when run on following code

Intent chooseImageIntent = ImagePicker.getPickImageIntent(ChildInfoActivity.this, "ChildInfo");

Do you have any advice how to solve this?

After debug the app failed at

takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", ImageUtils.getTemporalFile(context, String.valueOf(mPickImageRequestCode))));

in this code

if (!mGalleryOnly) {

        // Camera action will fail if the app does not have permission, check before adding intent.
        // We only need to add the camera intent if the app does not use the CAMERA permission
        // in the androidmanifest.xml
        // Or if the user has granted access to the camera.
        // See https://developer.android.com/reference/android/provider/MediaStore.html#ACTION_IMAGE_CAPTURE
        if (!appManifestContainsPermission(context, Manifest.permission.CAMERA) || hasCameraAccess(context)) {
            Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            takePhotoIntent.putExtra("return-data", true);
            takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                    FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider",
                            ImageUtils.getTemporalFile(context, String.valueOf(mPickImageRequestCode))));
            //Uri.fromFile(ImageUtils.getTemporalFile(context, String.valueOf(mPickImageRequestCode))));
            intentList = addIntentsToList(context, intentList, takePhotoIntent);
        }
    }

You need to add Runtime Uri Grant Permissions.

` if (!mGalleryOnly) { // Camera action will fail if the app does not have permission, check before adding intent. // We only need to add the camera intent if the app does not use the CAMERA permission // in the androidmanifest.xml // Or if the user has granted access to the camera. // See https://developer.android.com/reference/android/provider/MediaStore.html#ACTION_IMAGE_CAPTURE if (!appManifestContainsPermission(context, Manifest.permission.CAMERA) || hasCameraAccess(context)) { Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); takePhotoIntent.putExtra("return-data", true);

            Uri imageUri =  FileProvider.getUriForFile(context,BuildConfig.APPLICATION_ID + ".provider",ImageUtils.getTemporalFile(context, String.valueOf(mPickImageRequestCode)));
            takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT,imageUri);

            //Grant Runtime URi permissions
            List<ResolveInfo> resInfoList = context.getPackageManager().queryIntentActivities(takePhotoIntent, PackageManager.MATCH_DEFAULT_ONLY);
            for (ResolveInfo resolveInfo : resInfoList)
            {
                String packageName = resolveInfo.activityInfo.packageName;
                context.grantUriPermission(packageName, imageUri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
            }


            intentList = addIntentsToList(context, intentList, takePhotoIntent);
        }
    }`

@Code-N-K Thanks, it's work in my local test,

This issue duplicate with this issue NullPointerException on OnePlus3 Oreo

[songpr]

I've forked and apply change as shown in https://github.com/songpr/ImagePicker/blob/develop/library/src/main/java/com/mvc/imagepicker/ImagePicker.java

However, the same error is happen.

java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.res.XmlResourceParser android.content.pm.ProviderInfo.loadXmlMetaData(android.content.pm.PackageManager, java.lang.String)' on a null object reference at android.support.v4.content.FileProvider.parsePathStrategy(FileProvider.java:591) at android.support.v4.content.FileProvider.getPathStrategy(FileProvider.java:565) at android.support.v4.content.FileProvider.getUriForFile(FileProvider.java:403) at com.mvc.imagepicker.ImagePicker.getPickImageIntent(ImagePicker.java:219) at com.mvc.imagepicker.ImagePicker.startChooser(ImagePicker.java:189) at com.mvc.imagepicker.ImagePicker.pickImage(ImagePicker.java:180)

The change is work only when I took source code and build in the application, But do not work when add to project as library below.

dependencies { compile 'com.github.songpr:ImagePicker:f96bf8d' ....

So, we shall copy the library code, into our apps, in order, to get rid of the exception? Or Author will release newer version, with handling that exception?

[Code-N-K]

I have updated the author..

As we have the fix we could do it with libarary code also..

Until we get a new version with the said changes using the libarary will not work.

I've got another question. for some reason, it doens't seems to have a runtime permissions right? We have to handle the camera use and read from internal storage permissions from ourselves? Or I am missing something? The thing is that, whenever I am trying to turn on/off the permissions from my testing phone(also, re-installing the app) it never gives me the dialog about using it...

It seems like the only workaround for now is copying the source code instead of using it as a dependency. What worked for me:

1. Copy all the files in com/mvc/imagepicker to my project's src/main/java folder.
2. Adding a "pick_image_intent_text" in strings.xml
3. Modifying the imports for R and BuildConfig in ImagePicker.java

[songpr]

You can fork and fix in your repository then add dependency to your forked project. Try this https://github.com/Mariovc/ImagePicker/pull/46/commits/ae5687b5ea071e6015e1b46ec1f360dee285beae

[euri16]

Add this to the application tag of your Android Manifest:

        <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="com.mvc.imagepicker.provider"
            android:exported="false"
            android:grantUriPermissions="true"
            tools:replace="android:authorities">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths"
                tools:replace="android:resource"/>
        </provider>
