假设你想发送你自己的应用程序的.apk ,这很简单:

 // Get current ApplicationInfo to find .apk path ApplicationInfo app = getApplicationContext().getApplicationInfo(); String filePath = app.sourceDir; Intent intent = new Intent(Intent.ACTION_SEND); // MIME of .apk is "application/vnd.android.package-archive". // but Bluetooth does not accept this. Let's use "*/*" instead. intent.setType("*/*"); // Only use Bluetooth to send .apk intent.setPackage("com.android.bluetooth"); // Append file and send Intent intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(new File(filePath))); startActivity(Intent.createChooser(intent, "Share app"));
