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

Question

我正在将 CWAC StreamProvider 集成到我的代码中，但是在运行我的代码之后，我看到无法在 logcat 中获取提供程序 com.commonsware.cwac.provider.StreamProvider。我无法从互联网上的解决方案中解决它，因为我只找到了一些不适合我的解决方案。

提供商

     <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>

class

的变量

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

OnCreate 方法 为 share

定义了 longClickListener

     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;
                    }
                });

分享功能

      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());
}

Provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
  <paths xmlns:android="http://schemas.android.com/apk/res/android">
   <assets name="assets" path=""/>
  </paths>

Answer 1

android:authorities="cz.revelio.tomiookamura"

您的值是：cz.revelio.tomiookamura.

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

您的值是：com.anothergamedesigner.CatVimeoTest.

这些值不一样。它们必须相同。

此外，替换：

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

与：

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