在Android Studio中,我很难使用ShareCompatFileProvider共享音频文件...我以1个音频文件为例:

  

/storage/emulated/0/Music/JPlayer/Cornerstone.m4a

如果我运行代码并将音频文件共享到Whatsapp,它将在Whatsapp中显示以下消息:“共享失败,请重试” 如果我运行代码并将音频文件共享给电报,它将在电报中显示以下消息:不支持的附件

这是我的代码:

MainActivity.java

public class MainActivity extends AppCompatActivity {
    public static final int MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE = 123;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ActivityCompat.requestPermissions(this, Array(Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE), MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);

        final File file = new File("/storage/emulated/0/Music/JPlayer/Cornerstone.m4a");
        final Uri uri = FileProvider.getUriForFile(this, this.getPackageName() + ".provider", file);
        Intent intent = ShareCompat.IntentBuilder.from(this)
                .setType("audio/*")
                .setStream(uri)
                .setChooserTitle("Choose File client")
                .getIntent();

        List<ResolveInfo> resInfoList = getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
        for (ResolveInfo resolveInfo : resInfoList) {
            String packageName = resolveInfo.activityInfo.packageName;
            grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
        }

      startActivity(intent);
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    for (int i : grantResults) {
        if (i == PackageManager.PERMISSION_DENIED) {
            return;
        }
    }
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE:

            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    }
}

} Manifest.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>

xml / provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path name="external_files" path="."/>
</paths>
