create a signed jar in quick way.
It can run directly on android devices.
Here is an example
```
// sign asset/unsigned.apk and install it
public void a(Context ctx, File orgJar) {
// create a tmp dir for extract content in unsigend.jar
final File dir = ctx.getDir("tmp", Context.MODE_PRIVATE);
InputStream in = ctx.getAssets().open("unsigned.apk");
// do extract to tmp dir
extract(in, dir);
in.close();
File distFile = ctx.getFileStreamPath("signed.apk");
FileOutputStream fos = new FileOutputStream(distFile);
// do sign
TinySign.sign(dir, fos);
fos.close();
// install it
Intent promptInstall = new Intent(Intent.ACTION_VIEW);
promptInstall.setDataAndType(Uri.fromFile(distFile), "application/vnd.android.package-archive");
ctx.startActivity(promptInstall);
}
public static void extract(InputStream in, File dir) throws IOException {
ZipInputStream zis = new ZipInputStream(in);
for (ZipEntry e = zis.getNextEntry(); e !
