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

 

代碼以下：

    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);
    }

異常信息提示以下：

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)

調查以下：

1,若是手機中沒有能發送短信的app就會報出這樣的錯

2,手機中的能發送短信的應用被關閉了（設置-->應用-->app-->關閉）;

解決方法：爲了不有的手機沒有打開相應文件的app,在startActivity那裏作一個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);
    }
