FileProvider crash - npe attempting to invoke XmlResourceParser on a null String

Question

This is a part of my manifest:

Answer 1

You should try it:

  Context context = PostAdapter.this.activity;
                    StringBuilder stringBuilder2 = new StringBuilder();
                    stringBuilder2.append(PostAdapter.this.activity.getPackageName());
                    stringBuilder2.append(".provider");
                    Uri uri;
                    uri = FileProvider.getUriForFile(context,stringBuilder2.toString(), newFile);

Answer 2

Following worked for me.

mUri = FileProvider.getUriForFile(this,
                    BuildConfig.APPLICATION_ID + ".provider",
                    fileObject);

Answer 3

Here is what i did to fix the issue. I gave fully qualified name in android:name. It works in android 6,7,8

    <provider android:authorities="${applicationId}.opener.provider" 
        android:exported="false" android:grantUriPermissions="true" 
        android:name="io.github.pwlin.cordova.plugins.fileopener2.FileProvider">
        <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths" />
    </provider>
