CWAC error: Unable to get provider com.commonsware.cwac.provider.StreamProvider


I was integrating CWAC StreamProvider to my code, but after run my code, I saw Unable to get provider com.commonsware.cwac.provider.StreamProvider in logcat. I couldn't solve it from solutions on internet, because I found only a few solutions which not works for me.

Provider

     <provider
        android:name="com.commonsware.cwac.provider.StreamProvider"
        android:authorities="cz.revelio.tomiookamura"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data                
       android:name="com.commonsware.cwac.provider.STREAM_PROVIDER_PATHS"
            android:resource="@xml/provider_paths"/>
    </provider>

Variables for class

     private static final String AUTHORITY = "cz.revelio.tomiookamura";
private static final Uri PROVIDER = Uri.parse("content://"+AUTHORITY);
private static String ASSET_PATHS;

OnCreate method defined longClickListener for share

     button.setOnLongClickListener(new View.OnLongClickListener() {
                    @Override
                    public boolean onLongClick(View v) {
                        Bundle params = new Bundle();
                        params.putInt("ButtonId", v.getId());
                        String btnName = "share_"+soubor;
                        mFirebaseAnalytics.logEvent(btnName, params);
                        AssetManager assetManager = getAssets();
                        ASSET_PATHS = "assets/" + soubor+".mp3";
                            setShareIntent();


                        return false;
                    }
                });

Functions for share

      private Intent setShareIntent(){
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.setType("audio/*");

    shareIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] {""});
    shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Hláška");
    shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Text");
    shareIntent.putExtra(Intent.EXTRA_STREAM, getURI());
    shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    shareIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);

    return shareIntent;
}

private Uri getURI(){
    return(PROVIDER
            .buildUpon()
            .appendPath(StreamProvider.getUriPrefix(AUTHORITY))
            .appendPath(ASSET_PATHS)
            .build());
}

Solution

  • android:authorities="cz.revelio.tomiookamura"
    

    Your value here is: cz.revelio.tomiookamura.

    private static final String AUTHORITY = "com.anothergamedesigner.CatVimeoTest";
    

    Your value here is: com.anothergamedesigner.CatVimeoTest.

    These values are not the same. They need to be the same.


    Also, replace:

    <assets name="assets" path=""/>
    

    with:

    <asset name="assets" path=""/>
