[Q]Problem using RootTools library - Java for Android App Development

i am trying to list files of root folders using roottools libary .here is the code
Code:
public ArrayList<File> listFiles(final Context c,final String path) {
final ArrayList<File> a=new ArrayList<File>();
Command command = new Command(0, "ls "+path)
{
@Override
public void commandOutput(int i, String s) {
File f=new File(path+"/"+s);
a.add(f);}
@Override
public void commandTerminated(int i, String s) {
}
@Override
public void commandCompleted(int i, int i2) {
//want to arraylist return from here
}
};
try {
RootTools.getShell(true).add(command);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
now problem is that if i return arraylist<file> from the end of method,its size is zero,to solve it i must return the arraylist from commandCompleted
method.but i am not able to accomplish that.So please solve my problem

Maybee arraylist as static outside your function? So on top of source file? Not sure but maybee

Android ICS SSL Authentication Help

Im trying to build an RSS feed reader that needs to do some client side SSL authentication.
Ive got, or at least think i have, the certificate and now cannot figure out how to setup a ssl tunnel to send the certificate to the server to authenticate.
here is what i have so far:
public class Authenticator extends Activity {
PrivateKey privateKey = null;
String SavedAlias = "";
private static final String TAG = "AUTHENTICATOR.CLASS";
final HttpParams httpParams = new BasicHttpParams();
private KeyStore mKeyStore = KeyStore.getInstance();
public Handler mHandler = new Handler(Looper.getMainLooper());
public void run()
{
mHandler.post(new Runnable() {
public void run() {
new AliasLoader().execute();
}
});
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getCertificates("TEST");
}
public class AliasLoader extends AsyncTask<Void, Void, X509Certificate[]>
{
X509Certificate[] chain = null;
@Override protected X509Certificate[] doInBackground(Void... params) {
android.os.Debug.waitForDebugger();
if(!SavedAlias.isEmpty())
{
try {
chain = KeyChain.getCertificateChain(getApplicationContext(),SavedAlias);
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
}
else
{
this.cancel(true);
}
return chain;
}
@Override
protected void onPostExecute(X509Certificate[] chain)
{
if(chain != null)
{
Toast.makeText(getApplicationContext(), "YAY, Certificate is not empty", Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(getApplicationContext(), "Certificate is Empty", Toast.LENGTH_LONG).show();
}
/*
if (privateKey != null) {
Signature signature = null;
try {
signature = Signature.getInstance("SHA1withRSA");
} catch (NoSuchAlgorithmException e) {
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
try {
signature.initSign(privateKey);
} catch (InvalidKeyException e) {
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
}
*/
}
}
public void getCertificates(String Host)
{
KeyChainAliasCallback callBack = new KeyChainAliasCallback() {
@Override
public void alias(String alias) {
if (alias != null)
{
Looper.prepare();
saveAlias(alias);
run();
Looper.loop();
}
}
};
KeyChain.choosePrivateKeyAlias(this, callBack,
new String[] {"RSA", "DSA"}, // List of acceptable key types. null for any
null, // issuer, null for any
null, // host name of server requesting the cert, null if unavailable
443, // port of server requesting the cert, -1 if unavailable
null); // alias to preselect, null if unavailable
}
public void saveAlias(String alias)
{
SavedAlias = alias;
}
}
Any help on how to do this would be greatly appreciated as i have never done any authentication before and i have found it difficult to find anything on this topic for android 4.0 as 4.0 seems to be different in implementation then the older versions.

Problem of flashlight app code (Eclipse)

Hello everyone ..
I have problem on developing a flashlight app
I tried the solutions that provided by Eclipse but none solved the problem
or even make any sense to me :angel:
every "Void" statement on the code appeared as an error
and i don't know why .. also i'm sure that everything on the code is correct
Examples of the errors:
private void playSound() {
private void toggleButtonImage() {
private void turnOffFlash() {
and .. etc , i got an error on every "Void" !
so.. i'm waiting for your opinions
Thanks in advance )​
Hi,
It is impossible for us to tell you what you have done wrong if you do not post your source code.
It could be just one character missing somewhere or one to much.
We need your code to help you.
(If you do not want to release it completely, copy your project and remove those parts you do not want us to see. This could also help you with finding the error yourself. )

these work
Does it work on other projects?
It is working for him, so I guess that the errors are not in the code but maybe your project setup or your installation of Eclipse and the Android SDK is the reason for that.
So to quote myself " Does it work on other projects?".

Oh no, there are mistakes with the brackets.
For example you set a listener somewhere inside a methods. However, you forgot to close the bracket (I mean these ones {}). So it ends with a semicolon. It wants more lines of code.
So check your brackets.
Void methods should not return anything. So you can remove all 'return' words in the void methods.

These returns ARE allowed. They are not necessary but allowed. You can stop the method by this.
It is really a problem with these brackets {}.

i tried the code on a new project but i got the same errors

[Q] Copy Image from Gallery Share (Send To) menu

Moderators... It says I am breaking the rules by asking a question and to ask in the Q&A... But the title of this is "Coding Discussion, Q&A, and Educational Resources" I am not breaking the rules intentionally, I just don't know where else to put this. This is a Coding Question, not a General Question that I would think would get buried and or lost in the General Q&A forum. Please move if you feel I am incorrect.
Hello All, I was hoping someone could help me.
I am trying to create an app that will hide pictures. I want to be able to Pick my App from the Share (Send To) menu from the Users Gallery and have it copy the file to a Directory I have created on my SDCard and then ultimately delete the file from the current location.
Here is what I have so far, but when I pick my app from the Share menu, it crashes the Gallery app. So... I can't even see any errors in my LogCat to even try and troubleshoot my issue.
Can someone point me to a working example of how to do this (I have searched the internet until I am blue in the face) or... I hate to say it... Fix my Code?
Any Help would be appreciated... Thanks!!

What's the gallery log output?
Btw, you're not breaking the rules. This is the right forum for Java Q&A.

How would I get the Logs for the Gallery? I am using and HTC ONE and it's the standard Gallery. Nothing shows up in LogCat so I'm stuck

[\CODE]
When I import "uri" for my on activity results at the end of my code I get a bunch of errors for everything I'm doing with parse. I been searching and trying different image picker tutorials and always end up with same results. I've checked out parse.com but only see info on saving images from the drawable folder. If I can get the image picker to work I'm pretty sure I can figure out how to save it to parse.com.
