我需要通过Intents将arrayString或arrayList传递给whtsapp？

Question

[当我点击发送按钮时，我的whatsapp被停止并且什么都不做，甚至没有显示我在catch部分输入的toast。][1] 这是我的代码：

String[] arrStr1=new String[finalList.size()];
    finalList.toArray(arrStr1);

       // String smsNumber = "9212197079"; //without '+'
        try {
            Intent sendIntent = new Intent();//"android.intent.action.MAIN");
            //sendIntent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.Conversation"));
            sendIntent.setAction(Intent.ACTION_SEND);
            sendIntent.setType("text/plain");
            sendIntent.putExtra(Intent.EXTRA_TEXT, arrStr1);
                          // sendIntent.putStringArrayListExtra(Intent.EXTRA_TEXT,finalList);

           // sendIntent.putExtra("jid", smsNumber + "@s.whatsapp.net"); //phone number without "+" prefix
            sendIntent.setPackage("com.whatsapp");
            startActivity(sendIntent);
        } catch(Exception e) {
            Toast.makeText(this, "Error/n" + e.toString(), Toast.LENGTH_SHORT).show();
        }

喔!!!我在这里解决了问题是正确的代码......

 StringBuilder str=new StringBuilder();
        String[] arrStr=new String[finalList.size()];
        finalList.toArray(arrStr);

        for(i=0;i<arrStr.length;i++){
            str.append(arrStr[i]);
            str.append("\n");
        }



           // String smsNumber = "9212197079"; //without '+'
            try {
                Intent sendIntent = new Intent();//"android.intent.action.MAIN");
                //sendIntent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.Conversation"));
                sendIntent.setAction(Intent.ACTION_SEND);
                sendIntent.setType("text/plain");
                sendIntent.putExtra(Intent.EXTRA_TEXT, str.toString());
                // sendIntent.putStringArrayListExtra(Intent.EXTRA_TEXT,finalList);

               // sendIntent.putExtra("jid", smsNumber + "@s.whatsapp.net"); //phone number without "+" prefix
                sendIntent.setPackage("com.whatsapp");
                startActivity(sendIntent);
            } catch(Exception e) {
                Toast.makeText(this, "Error/n" + e.toString(), Toast.LENGTH_SHORT).show();
            }
