Answer 1

I tried on rooted Android 4.2.2 and this method works for me:

private void installApk(String filename) {
    File file = new File(filename); 
    if(file.exists()){
        try {   
            final String command = "pm install -r " + file.getAbsolutePath();
            Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command });
            proc.waitFor();
        } catch (Exception e) {
            e.printStackTrace();
        }
     }
}
