I have created an app that contains a button, when I click that button then another apk
that I have stored in resources folder should be install,

Heres something I have done :

public void onClick(View v) {
// Intent intent = new Intent("com.google.zxing.client.android.SCAN");
// intent.setPackage("com.google.zxing.client.android");
// intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
// startActivityForResult(intent, 0);
File file = new File("android.resource://com.app.barcodescanner/raw", "scan.apk");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
startActivity(intent);
}


any ideas ?
