如何将.mp3文件共享到whatsapp？

Question

我真的不明白如何将声音分享给whatsapp。

我想它是这样的：

btn.setOnLongClickListener(new View.OnLongClickListener() { 
    @Override 
    public boolean onLongClick(View v) { 



Uri uri = Uri.parse("android.resource://"+getPackageName()+"/raw/mySound"); 
      Intent share = new Intent(Intent.ACTION_SEND); 
      share.setType("audio/mp3"); 
      share.putExtra(Intent.EXTRA_STREAM, uri); 
      startActivity(Intent.createChooser(share, "Share Sound File")); 



      return true; 
     } 
    }); 

现在，如果我尝试点击了WhatsApp它说：“分享失败，请再试一次”

我在做什么错？我是新来的Android

我也试过这个代码：

 InputStream inputStream; 
     FileOutputStream fileOutputStream; 
     try { 
      inputStream = getResources().openRawResource(R.raw.testsound); 
      fileOutputStream = new FileOutputStream(
        new File(Environment.getExternalStorageDirectory(), "testsound.mp3")); 

      byte[] buffer = new byte[1024]; 
      int length; 
      while ((length = inputStream.read(buffer)) > 0) { 
       fileOutputStream.write(buffer, 0, length); 
      } 

      inputStream.close(); 
      fileOutputStream.close(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
      Toast.makeText(getApplicationContext(), "Sharing failed", Toast.LENGTH_LONG).show(); 

     } 

     Intent intent = new Intent(Intent.ACTION_SEND); 
     intent.putExtra(Intent.EXTRA_STREAM, 
       Uri.parse("file://" + Environment.getExternalStorageDirectory() + "/testsound.mp3")); 
     intent.setType("audio/mp3"); 
     startActivity(Intent.createChooser(intent, "Share sound"));

我不知道这是否是正确的URI。

Answer 1

Intent share = new Intent(Intent.ACTION_SEND); share.setType("audio/*"); 
share.putExtra(Intent.EXTRA_STREAM, uri); 
startActivity(Intent.createChooser(share, "Share Sound File"));
