when I perform my app, The following error occurs in android studio LOGCAT. How to solve this problem?

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 com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1374)

I added below in AndroidManifest.xml

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths"/>
    </provider>

and I added privider_paths file.

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path
        name="external_files"
        path="." />
    <root-path
        name="external_files"
        path="/storage/"/>
</paths>

and The error occurs this point

cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, FileProvider.getUriForFile(getApplicationContext(), BuildConfig.APPLICATION_ID+".FileProvider", file));

    Does this answer your question? [What is a NullPointerException, and how do I fix it?](https://stackoverflow.com/questions/218384/what-is-a-nullpointerexception-and-how-do-i-fix-it) – isaaaaame Jan 31 '20 at 09:05

    Use `cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, FileProvider.getUriForFile(getApplicationContext(), BuildConfig.APPLICATION_ID+".provider", file));` and see if its working – Manohar Jan 31 '20 at 09:12
  • Your provider_path.xml is incorrect, read the LOGS carefully. Check for correct formatting. Which library are you using? check the documentation for it to place correct path in privider_paths.xml. And even sometimes in rare cases android:authorities="${applicationId}.provider" this doesn't works properly as expected. Place the package name statically. – Blu Jan 31 '20 at 10:18

try this inside of your application tag

<application
        android:requestLegacyExternalStorage="true">
</application>
