如何使Android应用程序具有发送自己的能力

Nav*_*chi 2 android bluetooth apk

是不是有可能Android应用程序在运行时制作自己的apk文件?

我希望我的应用程序能够通过蓝牙发送自己如何做到这一点?

最好的方法是:

// 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"));
