Q:

Prase error ther was a probleme prasing the package

I try to send an .apk from server to my device (emulator and tablet), and I install it like this:
public void onClick(View v) {
    Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setDataAndType(Uri.fromFile(new File("/data/data/com.so.and/s.apk")), "application/vnd.android.package-archive");
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }
});

In the emulator I have this error: Parse error there was a problem parsing the package.
On my tablet the error is: un probléme est survenu lors de l'analyse du kit (a problem occurred during the analysis kit).

A:

It caused by many problems:

incompatible SDK
error in path
you don't have permission to launch your file.apk, for example if you are in data/data/com.exemple.app
go to setting security check source unknown
damage file when you make your download (retry)
