【问题描述】：

这是我的代码，我试图使用意图将图像发送到 whtsapp，但它给出了文件未找到异常

Uri uri = Uri.parse("android.resource://com.company.demoapp/" + resId);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_TEXT, "this is a new url");
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_STREAM,uri);
intent.setType("image/jpeg");
intent.setPackage("com.whatsapp");
mContext.startActivity(intent);

【问题讨论】：

确保您的文件路径正确且文件是否存在。

@md gouse 你试试我的回答吗

@PriyankPatel 文件路径已正确定义

不，请帮助...@Arjunsaini

Shymaa Othman Answer here working fine as you want

您还需要在 android mainfest 中授予权限

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

对于 Android 6.0 及更高版本也需要 WRITE_EXTERNAL_STORAGE 的运行时权限

private static final int REQUEST_RUNTIME_PERMISSION = 123;

 if (CheckPermission(youactivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) 

      shareImageWhatsApp();


     else 
      // you do not have permission go request runtime permissions
      RequestPermission(AccesspointCheck.this, Manifest.permission.WRITE_EXTERNAL_STORAGE, REQUEST_RUNTIME_PERMISSION);
    




public void RequestPermission(Activity thisActivity, String Permission, int Code) 
  if (ContextCompat.checkSelfPermission(thisActivity,
          Permission)
          != PackageManager.PERMISSION_GRANTED) 
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            Permission)) 
      shareImageWhatsApp();


     else 
      ActivityCompat.requestPermissions(thisActivity,
              new String[]Permission,
              Code);
    
  


public boolean CheckPermission(Activity context, String Permission) 
  if (ContextCompat.checkSelfPermission(context,
          Permission) == PackageManager.PERMISSION_GRANTED) 
    return true;
   else 
    return false;
  

在课堂上调用 shareImageWhatsApp

public void shareImageWhatsApp() 

  Bitmap adv = BitmapFactory.decodeResource(getResources(), R.drawable.launcher_icon);
  Intent share = new Intent(Intent.ACTION_SEND);
  share.setType("image/jpeg");
  ByteArrayOutputStream bytes = new ByteArrayOutputStream();
  adv.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
  File f = new File(Environment.getExternalStorageDirectory()
          + File.separator + "temporary_file.jpg");
  try 
    f.createNewFile();
    new FileOutputStream(f).write(bytes.toByteArray());
   catch (IOException e) 
    e.printStackTrace();
  
  share.putExtra(Intent.EXTRA_STREAM,
          Uri.parse( Environment.getExternalStorageDirectory()+ File.separator+"temporary_file.jpg"));
  if(isPackageInstalled("com.whatsapp",this))
    share.setPackage("com.whatsapp");
    startActivity(Intent.createChooser(share, "Share Image"));

  else

    Toast.makeText(getApplicationContext(), "Please Install Whatsapp", Toast.LENGTH_LONG).show();
  



private boolean isPackageInstalled(String packagename, Context context) 
  PackageManager pm = context.getPackageManager();
  try 
    pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
    return true;
   catch (PackageManager.NameNotFoundException e) 
    return false;
  

【讨论】：

你传入参数的REQUEST_RUNTIME_PERMISSION是什么。

私有静态最终 int REQUEST_RUNTIME_PERMISSION = 123;
