我要发送的.apk文件。但我不能够给它通过蓝牙或WiFi直接或任何其他方式发送。

I want to send .apk file. but i am not able to send it via bluetooth or wifi-direct or any other way.

我已经尝试了一切。我可以轻松地发送过电子邮件，但同样不是通过意图，而是通过邮件API。

i have tried everything. i can easily send through e-mail but that too not via Intents but through Mail API.

请在下面找到我的code。

please find below my Code.

public void sendIntent(int x) throws Exception{
        Intent sendIntent = new Intent();
        sendIntent.setAction(Intent.ACTION_SEND);
        sendIntent.putExtra(Intent.EXTRA_TEXT, appnametosend);
        sendIntent.putExtra(Intent.EXTRA_STREAM, getApplicationPath(x));
        sendIntent.setType("application/vnd.android.package-archive");


        startActivity(sendIntent);
    }

下面是我的logcat：

请帮助。

推荐答案

首先，的setType（）需要一个MIME类型。路径是不是一个MIME类型。

First, setType() takes a MIME type. A path is not a MIME type.

其次，您需要使用 EXTRA_STREAM 发送二进制附件。

Second, you would need to use EXTRA_STREAM to send a binary attachment.

三，我不认为其他的应用程序是一定能够从 getApplicationPath阅读APK（X）。

Third, I would not assume that other apps are necessarily capable of reading the APK from getApplicationPath(x).
