【问题描述】：

这是我通过它将我的图像或视频从适配器共享到 WhatsApp 的代码，它工作正常，但现在只显示吐司没有安装什么应用程序，代码中有任何问题我错过了什么吗？

public void shareWhatsapp(String type, String path, String package_name) 

        Uri uri = FileProvider.getUriForFile(mFragment, BuildConfig.APPLICATION_ID + ".provider", new File(path));

        PackageManager pm = mFragment.getPackageManager();
        try 
            PackageInfo info = pm.getPackageInfo(package_name, PackageManager.GET_META_DATA);
            Intent sharingIntent = new Intent(Intent.ACTION_SEND);
            sharingIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            sharingIntent.setType(type);
            sharingIntent.putExtra(Intent.EXTRA_STREAM, uri);
            sharingIntent.setPackage(package_name);
            mFragment.startActivity(Intent.createChooser(sharingIntent, "Share via"));
         catch (PackageManager.NameNotFoundException e) 
            Toast.makeText(mFragment, "WhatsApp not Installed", Toast.LENGTH_SHORT)
                    .show();
        
    

这里是听众

   holder.repostWhatsapp.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View v) 
                final ModelStatus curVideo = getItem(position);
                if (curVideo.getFull_path().endsWith(".jpg")) 
                    shareWhatsapp("image/jpg", curVideo.getFull_path(), "com.whatsapp");
                 else if (curVideo.getFull_path().endsWith(".mp4")) 
                    shareWhatsapp("video/mp4", curVideo.getFull_path(), "com.whatsapp");
                
            
        );

【参考方案1】：

使用以下代码将图像或视频分享到whatsapp

 holder.repostWhatsapp.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View v) 
              Uri uri = FileProvider.getUriForFile(PdfRendererActivity.this, 
              PdfRendererActivity.this.getPackageName() + ".provider", outputFile);
        
                 if (curVideo.getFull_path().endsWith(".jpg")) 
                            shareWhatsapp("image/jpg", uri);
                         else if (curVideo.getFull_path().endsWith(".mp4")) 
                            shareWhatsapp("video/mp4", uri);
                         
                    
                );

  

分享WhatsApp

void shareWhatsapp(String type, String uri)

Intent share = new Intent();
share.setAction(Intent.ACTION_SEND);
share.setType(type);
share.putExtra(Intent.EXTRA_STREAM, uri);
share.setPackage("com.whatsapp");
startActivity(share);

【讨论】：

我还有一个关于 facebook 和 Instagram 的问题

if (curVideo.getFull_path().endsWith(".jpg")) shareInstagram("image/jpg", curVideo.getFull_path(), "com.instagram.android"); else if (curVideo.getFull_path().endsWith(".mp4")) shareInstagram("video/mp4", curVideo.getFull_path(), "com.instagram.android");

相同的代码，但包是为 facebook 的

com.facebook.katana
