Couldn't find meta-data for provider with authority

Question

I have integrated Snapchat\'s Creative Kit in my Android app. After processing, I receive an image from the server in the form of Byte Array which I am saving to the disk an

Answer 1

In My Case;

Manifest File:

<provider
    android:name="androidx.core.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>

Code:

import androidx.multidex.BuildConfig // NOT DO THIS!!!

val uri = FileProvider.getUriForFile(this,
            BuildConfig.APPLICATION_ID+ ".provider", _tempFile)

Exception:

java.lang.IllegalArgumentException: Couldn't find meta-data for provider with authority androidx.multidex.provider

Do not use androidx.multidex.BuildConfig, Because this values are not the values of our application:

//

package androidx.multidex;

public final class BuildConfig {
    public static final boolean DEBUG = false;
    public static final String APPLICATION_ID = "androidx.multidex";
    public static final String BUILD_TYPE = "release";
    public static final String FLAVOR = "";
    public static final int VERSION_CODE = -1;
    public static final String VERSION_NAME = "";

    public BuildConfig() {
    }
}

Answer 2

mImageFromCamera = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".fileprovider", mImageFile); android:authorities="${applicationId}.fileprovider"

authorities must be same in xml and in code

Answer 3

Change the authorities to a unique name to solve the issue like

android:authorities="${applicationId}.myUniquefileprovider"

also in java code

Answer 4

In my case.

I have a library project .Let's call it :LibApk

When I code this : applicationId "my.package.name" in the build.grale(app)

when build gradle tell me that : Library projects cannot set applicationId.

applicationId is set to 'com.darcy.apkupdate' in default config.

So ,I delete applicationId "my.package.name" .

Then ,build.gradle look like this :

But I forgot update the AndroidManifest.xml file which use ${applicationId}

This is the problem!!!

So I changed the variable to constant .The result looks like below picture:

After This ,It's wokr for me!

Hope this is help you...
