使用意向并发送通过蓝牙发送文件并不在android系统4.2.2工作吗？ [英] Sending File via Bluetooth using Intent Action SEND does not working in android 4.2.2?

问题描述

我已经使用意向SEND共享的文件通过bluetooth.I这里加我的code。

I have used Intent-SEND to share the files via bluetooth.I have add my code here.

    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_SEND);       
    intent.setComponent(new ComponentName("com.android.bluetooth",
            "com.android.bluetooth.opp.BluetoothOppLauncherActivity"));

    intent.setType("text/plain");

    File file = new File(Environment.getExternalStorageDirectory()
            .getAbsolutePath() + "/Sample.txt");
     intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
    startActivity(intent);

这code未在Android版本4.2.2工作。当运行在android系统verison 4.2.2，得到这个异​​常code：

This code is not working in android version 4.2.2. While running this code in android verison 4.2.2 , getting Exception:

        android.content.ActivityNotFoundException: Unable to find explicit activity   class {com.android.bluetooth/com.android.bluetooth.opp.BluetoothOppLauncherActivity}; have you declared this activity in your AndroidManifest.xml?

但是，这code以下的Andr​​oid 4.2.X.工作正常为什么这个code未在安卓4.2.2工作？

But this code working fine in below android 4.2.X. why this code is not working in android 4.2.2?.

推荐答案

您可以通过这样的蓝牙共享文件：

You can share the file by bluetooth like this:

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(picURI);
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Sample.txt");

sharingIntent.setType("text/plain");
sharingIntent.setPackage("com.android.bluetooth");
sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
startActivity(Intent.createChooser(sharingIntent, "Share file"));
