android.content.ActivityNotFoundException: No Activity found to handle Intent

代碼如下：

    public void sendMessage(String number) {        if (TextUtils.isEmpty(number)) {            return;        }        Intent intent = new Intent(Intent.ACTION_SENDTO,                Uri.fromParts(Constants.SCHEME_SMS, number, null));        context.startActivity(intent);    }

異常資訊提示如下：

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.SENDTO dat=sms:xxxxxxxxxxx } 

    at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1632)

    at android.app.Instrumentation.execStartActivity(Instrumentation.java:1424)

    at android.app.Activity.startActivityForResult(Activity.java:3424)

調查如下：

1,如果手機中沒有能傳送簡訊的app就會報出這樣的錯

2,手機中的能傳送簡訊的應用被關閉了（設定-->應用-->app-->關閉）;

解決方案：為了避免有的手機沒有開啟相應檔案的app,在startActivity那裡做一個try catch

    public void sendMessage(String number) {        if (TextUtils.isEmpty(number)) {            return;        }        Intent intent = new Intent(Intent.ACTION_SENDTO,                Uri.fromParts(Constants.SCHEME_SMS, number, null));        try {            context.startActivity(intent);        } catch(ActivityNotFoundException exception) {            Toast.makeText(this, "no activity", Toast.LENGTH_SHORT).show();        }    }

or 調用系統方法判斷是否有對應的app

     public void sendMessage(String number) {        if (TextUtils.isEmpty(number)) {            return;        }        Intent intent = new Intent(Intent.ACTION_SENDTO,                Uri.fromParts(Constants.SCHEME_SMS, number, null));                PackageManager packageManager = getPackageManager();        List<ResolveInfo>applist = packageManager.queryIntentActivities(intent, 0);        if (applist == null || applist.isEmpty()) {            Toast.makeText(this, "no activity", Toast.LENGTH_SHORT).show();            return;        }        context.startActivity(intent);    }
