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.
Hi everyone.
I want to retrieve the current cpu frequency in my app but I don't seem to be right.
In my code I want to read the "scaling_cpu_freq" file from internal storage.
This is the code:
Code:
private String ReadCPUMhz() {
String cpuMaxFreq = "";
int cur = 0;
try {
[user=1299008]@supp[/user]ressWarnings("resource")
BufferedReader maxi = new BufferedReader(new FileReader(new File("/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq")));
try{
cpuMaxFreq = maxi.readLine();
cur = Integer.parseInt(cpuMaxFreq);
cur = cur/1000;
} catch (Exception ex){
ex.printStackTrace();
}
} catch (FileNotFoundException f) {
f.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return String.valueOf(cur);
}
The problem is that the method only returns 0, which is the initial value of the int "cur".
Can anybody help me?
Thanks in advance.
Here's the code I use:
Declare this class in your Activity
Code:
// Read current frequency from /sys in a separate thread
// This class assumes your TextView is declared and referenced in the OnCreate of the class this one is declared in
// And its variable name is mCurCpuFreq
protected class CurCPUThread extends Thread {
private static final String CURRENT_CPU = "/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq";
private boolean mInterrupt = false;
public void interrupt() {
mInterrupt = true;
}
[user=439709]@override[/user]
public void run() {
try {
while (!mInterrupt) {
sleep(400);
final String curFreq = readOneLine(CURRENT_CPU);
mCurCPUHandler.sendMessage(mCurCPUHandler.obtainMessage(0,
curFreq));
}
} catch (InterruptedException e) {
return;
}
}
}
// Update real-time current frequency & stats in a separate thread
protected static Handler mCurCPUHandler = new Handler() {
public void handleMessage(Message msg) {
mCurFreq.setText(toMHz((String) msg.obj));
final int p = Integer.parseInt((String) msg.obj);
new Thread(new Runnable() {
public void run() {
// Here I update a real-time graph of the current freq
}
}
}).start();
}
};
Helper methods used :
Code:
// Convert raw collected values to formatted MhZ
private static String toMHz(String mhzString) {
if (Integer.valueOf(mhzString) != null)
return String.valueOf(Integer.valueOf(mhzString) / 1000) + " MHz";
else
return "NaN";
}
// Iterate through the /sys file
public static String readOneLine(String fname) {
BufferedReader br;
String line = null;
try {
br = new BufferedReader(new FileReader(fname), 512);
try {
line = br.readLine();
} finally {
br.close();
}
} catch (Exception e) {
Log.e(TAG, "IO Exception when reading sys file", e);
// attempt to do magic!
return readFileViaShell(fname, true);
}
return line;
}
// Backup method if the above one fails
public static String readFileViaShell(String filePath, boolean useSu) {
CommandResult cr = null;
if (useSu) {
cr = new CMDProcessor().runSuCommand("cat " + filePath);
} else {
cr = new CMDProcessor().runShellCommand("cat " + filePath);
}
if (cr.success())
return cr.getStdout();
return null;
}

Dear all , How are you
I have an Android application , the Developer of it chose to stop the support for it.
Any way i want to fix the bug,
I am not that expert with Java so i am seeking for help
The error that the app return when it get data from the database is :
Code:
11-14 15:42:26.420 W/SQLiteConnectionPool(15763): A SQLiteConnection object for database '/data/data/com.bookscars.src.v65/databases/AppDbStoreroot7' was leaked! Please fix your application to end transactions in progress properly and to close the database when it is no longer needed.
Now i did decompile the APK , search for the class who call AppDbStoreroot7 database to see what we can do for it ! and i found it,
Please note that i need to edit on the Smali code
what i need to know , where i need to put the close commad since i am not a JAVA expert

[\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.
Sent from my Nexus 6 using XDA Free mobile app
so i have been working on an app for a while now but now my code is crashing due to no empty constructor.
but i have no more idea how i should fix this.

I am sorry i don't understand. can you explain ?
I am not sure, but your class might be missing constructor
more info: http://www.javatpoint.com/constructor
For some reason it says that it needs and Empty constructor.
Type inside ChooserAppSettings class:
Code:
public ChooserAppSettings(){
}
This may fix it. I am not sure though why it needs the empty constructor. What class is your ChooserAppSettings extending or implementing??
Can you show all the logcat messages?

Linearlayout.
Tried the above but didnt worked
Try adding these:
Code:
public ChooserAppSettings(Context context){
super(context);
}
public ChooserAppSettings(Context context, AttributeSet attrs, int defStyle){
super(context, attrs, defStyle);
}
Issue solved.
was a stupid fault of myself xD
typo at launching the java file
