Hello I tried to install app inside of my app via Process. For that function I created this method.
private void loadAndInstallApk(String string) {
if(!isRooted()){
return;
}
Uri uri = loadApk(string);
if(uri == null){
return;
}
Process p = null;
DataOutputStream outs = null;
try
{
p = Runtime.getRuntime().exec(new String[]{"su", "-c", "system/bin/sh"});
outs=new DataOutputStream(p.getOutputStream());
String cmd="pm install -r " + uri.getPath();
Log.d(TAG, "DATA = cmd = " + cmd);
outs.writeBytes(cmd + "\n");
// Close the terminal
outs.writeBytes("exit\n");
outs.flush();
p.waitFor();
if (p.exitValue() != 255) {
Log.d(TAG, "DATA succerss " + p.exitValue());
// Sucess
}
else {
Log.d(TAG, "DATA Fail " + p.exitValue());
// Fail
}
}
catch (IOException e){
Log.e("Error", e.toString(), e);
} catch (InterruptedException e) {
Log.e("Error", e.toString(), e);
} finally {
if(outs != null) {
try {
outs.close();
} catch (IOException e) {
Log.d(TAG, e.toString(), e);
}
}
try {
File f = new File(uri.getPath());
f.delete();
}catch (NullPointerException e) {
Log.e(TAG, "DATA = finally delete " + e.toString(), e);
}
}
}
But it fails when it calls
outs.writeBytes(cmd + "\n");
Error message:

Instead of
Runtime.getRuntime().exec(new String[]{"su", "-c", "system/bin/sh"});
I tried:
Runtime.getRuntime().exec("su");
It didn't help.
Also this code work for my root tablet but it doesn't work for my TV box.
I check device on root via methods:
private static boolean isRooted() {
return findBinary("su");
}
public static boolean findBinary(String binaryName) {
boolean found = false;
if (!found) {
String[] places = {"/sbin/", "/system/bin/", "/system/xbin/", "/data/local/xbin/",
"/data/local/bin/", "/system/sd/xbin/", "/system/bin/failsafe/", "/data/local/"};
for (String where : places) {
Log.d(TAG, "DATA where = " + where);
if ( new File( where + binaryName ).exists() ) {
found = true;
break;
}
}
}
return found;
}
It return true.
