Android Install apk silently by busybox command-line

Question

I want to install .apk silently in background by BusyBox command. I`ve seen some similar questions like THIS, but I still cant get working my code properly...

I have:

1. My .apk I need to install on /sdcard/download/app.apk
2. Root
3. BusyBox installed

Code (not working):

String sss = Environment.getExternalStorageDirectory() + "/download/" + "app.apk";
Process install;
install = Runtime.getRuntime().exec("/system/xbin/busybox pm install " + sss); 
int success = install.waitFor();

If I use "install" instead of "pm install" it copies file well.

P.S. Code above is executing in AsyncTask. No errors, but also nothing happens... Please help!

Also I tried this, but I`m getting exit value 139 and no result:

        Process process;
        process = Runtime.getRuntime().exec("su");
        DataOutputStream os = new DataOutputStream(process.getOutputStream());
        os.writeBytes("pm install /mnt/sdcard/app.apk\n");
        os.flush();
        os.writeBytes("exit\n");
        os.flush();

        int i = process.waitFor();

Answer 1

After a lot of investigations on many android devices I realized that this code is correct and works!

There was just some problem with one device (Samsung Galaxy Tab 2 7.0 - 4.0.3 ICS). Maybe that is some strange feature of ICS. After updating firmware to 4.1.2 (Jelly Bean) problem has been resolved.

maybe this code will help you

Process p = null;
try
{
    p = Runtime.getRuntime().exec("su");
    DataOutputStream outs=new DataOutputStream(p.getOutputStream());

    String cmd="pm install /mnt/sdcard/app.apk";
    outs.writeBytes(cmd+"\n");
}
catch (IOException e)
{
    e.printStackTrace();
}

You can simply use adb install command to install/update APK silently. Sample code is below

public static void InstallAPK(String filename){
    File file = new File(filename); 
    if(file.exists()){
        try {   
            String command;
            filename = StringUtil.insertEscape(filename);
            command = "adb install -r " + filename;
            Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command });
            proc.waitFor();
        } catch (Exception e) {
        e.printStackTrace();
        }
     }
  }
