Bluetooth Opp发送文件

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

intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/Ludimate.sisx"));
// imageUri set previously
intent.setType("**");
values.put("destination", mDevice.getAddress());
values.put("direction", 0);
values.put("VISIBILITY", 1);
values.put("is_push", 1);
contxt.getContentResolver().insert(CONTENT_URI, values);
Intent intent = new Intent(
"android.bluetooth.devicepicker.action.DEVICE_SELECTED");
intent.setClassName("com.android.bluetooth",
"com.android.bluetooth.opp.BluetoothOppReceiver");
intent.putExtra(BluetoothDevice.EXTRA_DEVICE, mDevice);
sendBroadcast(intent);
// Intent intent = new Intent(Intent.ACTION_SEND);
// intent.setClassName("com.android.bluetooth","com.android.bluetooth.opp.BluetoothOppLauncherActivity");
// intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/Ludimate.sisx"));
// // imageUri set previously
// intent.setType("*/*");
// startActivity(intent);

我们在实现共享功能的时候，通常使用的是Intent intent = new Intent(Intent.ACTION_SEND)这样的代码，这种情况会弹出一个共享功能的选择界面，比如通过微博、蓝牙、邮件等等很多途径，现在我要实现的是跳过这个选择界面，直接选用蓝牙途径进行共享文件，代码如下

/** 蓝牙功能包名 /

private final String mBluetoothPackageName = "com.android.bluetooth";
/* 蓝牙功能操作类名 */
private final String mBluetoothClassName = "com.android.bluetooth.opp.BluetoothOppLauncherActivity";

mSelfApkPath = getSelfAPKPath(mSelfApkPackage);
File file = new File(mSelfApkPath);
Intent intent = new Intent();
try {
intent.setAction(android.content.Intent.ACTION_SEND);
intent.setType("*/*");
// 以下此行代码功能为直接指向系统蓝牙搜索设备界面，去掉即跳转至客户端选择分享途径
intent.setClassName(mBluetoothPackageName, mBluetoothClassName);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
startActivity(intent);
} catch (Exception e) {
Toast.makeText(this, "该设备可能不支持蓝牙功能...",Toast.LENGTH_SHORT).show();
}

在实现过程中，手中的测试机器在执行到startActivity(intent)时并不会抛异常，而后面无意中却发现有的手机在这句程序居然抛出了异常，异常信息如下：

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?
