  • How to show a ProgressDialog while changing from a activity to another activity?

    - by AndroidUser99
    i want to show a PD when my activity A starts another activity B. But in that onclick method, my A activity haves to do some work before start B, and B also haves to do some work because it haves to load a lot of data for the UI. I need a PD that is viewed by the user in all the process of the loading data of changin from activity A to B. ¿how can do it? i tryed storing a static ProgressDialog on MyApplication.java, and with these methods: public static void showProgressDialog(Context c) { pd = ProgressDialog.show(c, c.getResources().getString(R.string.app_name), c.getResources().getString(R.string.loading), true, false); } public static void dismissProgressDialog(){ pd.dismiss(); } but it doesn't works, it doesn't shows nothing, i dont know why how to achieve this by a easy way? i know that i can do it with async task, but that is too hard for me, i can't understand the code examples i am finding on this web and google code examples are welcome thanks

  • Accept All Cookies via HttpClient

    - by Vinay
    So this is currently how my app is set up: 1.) Login Activity. 2.) Once logged in, other activities may be fired up that use PHP scripts that require the cookies sent from logging in. I am using one HttpClient across my app to ensure that the same cookies are used, but my problem is that I am getting 2 of the 3 cookies rejected. I do not care about the validity of the cookies, but I do need them to be accepted. I tried setting the CookiePolicy, but that hasn't worked either. This is what logcat is saying: 11-26 10:33:57.613: WARN/ResponseProcessCookies(271): Cookie rejected: "[version: 0] [name: cookie_user_id][value: 1][domain: www.trackallthethings.com][path: trackallthethings][expiry: Sun Nov 25 11:33:00 CST 2012]". Illegal path attribute "trackallthethings". Path of origin: "/mobile-api/login.php" 11-26 10:33:57.593: WARN/ResponseProcessCookies(271): Cookie rejected: "[version: 0][name: cookie_session_id][value: 1985208971][domain: www.trackallthethings.com][path: trackallthethings][expiry: Sun Nov 25 11:33:00 CST 2012]". Illegal path attribute "trackallthethings". Path of origin: "/mobile-api/login.php" I am sure that my actual code is correct (my app still logs in correctly, just doesn't accept the aforementioned cookies), but here it is anyway: HttpGet httpget = new HttpGet(//MY URL); HttpResponse response; response = Main.httpclient.execute(httpget); HttpEntity entity = response.getEntity(); InputStream in = entity.getContent(); BufferedReader reader = new BufferedReader(new InputStreamReader(in)); StringBuilder sb = new StringBuilder(); From here I use the StringBuilder to simply get the String of the response. Nothing fancy. I understand that the reason my cookies are being rejected is because of an "Illegal path attribute" (I am running a script at /mobile-api/login.php whereas the cookie will return with a path of just "/" for trackallthethings), but I would like to accept the cookies anyhow. Is there a way to do this?

  • AsyncTask Threading Rule - Can it really only be used once?

    - by stormin986
    In the documentation on AsyncTask it gives the following as a rule related to threading: The task can be executed only once (an exception will be thrown if a second execution is attempted.) All this means is that you have to create a new instance of the class every time you want to use it, right? In other words, it must be done like this: new DownloadFilesTask().execute(url1, url2, url3); new DownloadFilesTask().execute(url4, url5, url6); Or conversely, you can NOT do the following: DownloadFilesTask dfTask = new DownloadFilesTask(); dfTask().execute(url1, url2, url3); dfTask().execute(url4, url5, url6); Can someone verify this is an accurate interpretation? I realize I pretty much just answered this for myself as I was typing this out... But it wasn't immediately obvious to me so I think this would be useful to have posted nonetheless.

  • APK Assets not loaded on Kindle Fire HD

    - by Bastl
    I have developed an App for the Amazon Kindle Fire HD. While distributing I got a report from amazon that its not running on almost all Kindle devices and a blackscreen is displayed. They send me a logcat log file and I found out that it's not possible to load some assets directly from APK file (accessing via C++ and zlib). Everything is running fine if I start it via Eclipse. Any idea whats going wrong? Thanks!

  • How do I get parameters between activities?

    - by Matt
    I am working on an app that has multiple tabs. In the first tab the user will enter values. In the other tabs it will display the results of calculations based off of those values. Like in tab 1, the user will enter "3" and "2". In tab 2, the program will add them and display "5". In tab 2 how do I access the ints "3" and "2"? Thanks

  • Dismiss a custom dialog?

    - by YaW
    Hi, I'm trying to make a custom dialog to show a view in this dialog. This is the Builder code: //Getting the layout LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.custom_dialog_simple, (ViewGroup) findViewById(R.id.rlDialogSimple)); //Change Text and on click TextView tvDialogSimple = (TextView) layout.findViewById(R.id.tvDialogSimple); tvDialogSimple.setText(R.string.avisoComprobar); Button btDialogSimple = (Button) layout.findViewById(R.id.btDialogSimple); btDialogSimple.setOnClickListener(new OnClickListener() { public void onClick(View v) { //Do some stuff //Here i want to close the dialog } }); AlertDialog.Builder builder = new AlertDialog.Builder(AcPanelEditor.this); builder.setView(layout); AlertDialog alert = builder.create(); alert.show(); So, i want to dismiss the dialog in the onClick of btDialogSimple. How i can do it? I don't know how to call the dismiss method from inside a onclicklistener. My buttons have a custom layout, so i don't want to make a builder.setPositiveButton. Any ideas?

  • Texture repeats even with GL_CLAMP_TO_EDGE set

    - by Lliane
    Hi, i'm trying to put a translucing texture on a face which uses points 1 to 4 (don't mind the numbers) on the following screenshot Sadly as you can see the texture repeats herself in both dimensions, I tried to switch the TEXTURE_WRAP_S from REPEAT to CLAMP_to_EDGE but it doesn't change anything. Texture loading code is here : gl.glBindTexture(gl.GL_TEXTURE_2D, mTexture.get(4)); gl.glActiveTexture(4); gl.glTexParameterf(gl.GL_TEXTURE_2D, gl.GL_TEXTURE_MIN_FILTER, gl.GL_LINEAR); gl.glTexParameterf(gl.GL_TEXTURE_2D, gl.GL_TEXTURE_MAG_FILTER, gl.GL_LINEAR); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_S, GL10.GL_CLAMP_TO_EDGE); gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_WRAP_T, GL10.GL_CLAMP_TO_EDGE); gl.glTexImage2D(gl.GL_TEXTURE_2D, 0, gl.GL_RGBA, shadowbmp.width, shadowbmp.height, 0, gl.GL_RGBA, gl.GL_UNSIGNED_SHORT_4_4_4_4, shadowbmp.buffer); Texture coordinates are the following : float shadow_bot_text[] = { 0.0f, 0.0f, 0.0f, 1.0f, 1.0f, 0.0f, 1.0f, 1.0f }; Thanks

  • Runnable to be run every second only runs once in Fragment onCreateView()

    - by jul
    I'm trying to update the time in a TextView with a Runnable supposed to be run every second. The Runnable is started from a Fragment's onCreateView(), but it's only executed once. Anybody can help?

    - by Sponge
    i have written a object selection algorithm which picks the objects by there color. i give every object an unique color and then i just have to use the glReadPixels method to check which object was selected this works fine and is really fast but the problem is that the frame is displayed on the screen with all the picking-colors so the screen flashes every time you select something. so my question is: how do i write everything in the correct display buffer but dont display it on the screen to avoid these flashes?

  • Reading data from database and binding them to custom ListView

  • NullPointerException on Activity Testing Tutorial

    - by Bendik
    Hello, I am currently trying the activity testing tutorial (Found here), and have a problem. It seems that whenever I try to call something inside the UIThread, I get a java.lang.NullPointerException. public void testSpinnerUI() { mActivity.runOnUiThread( new Runnable() { public void run() { mSpinner.requestFocus(); } }); } This gives me: Incomplete: java.lang.NullPointerException and nothing else. I have tried this on two different samples now, with the same result. I tried with a try/catch clause around the mSpinner.requestFocus() call, and it seems that mSpinner is null inside the thread. I have set it properly up with the setUp() function found in the same sample, and a quick assertNotNull( mSpinner ) shows me that mSpinner is in fact not null after the setUp() function. What can be the cause of this? EDIT; ok, some more testing has been done. It seems that the application that is being tested resets between each test. This essentially makes me have to reinstantiate all variables between each test. Is this normal?

  • Bitmap .compress() returning false

    - by Tsimmi
    Hi! The next call to Bitmap.compress(), has a different behavior on the Emulator and on a real device. In the Emulator, result is true, and in a real device the same call returns false. FileOutputStream fos = new FileOutputStream(destinationFile, true); boolean result = myBitmap.compress(Bitmap.CompressFormat.PNG, 100, fos); The thing is that on the emulator this is working great, on a real device ( a HERO) when calling .compress(), this returns false, witch means that it was unable to convert the image properly. Why is this? Thank you

  • What values does Camera.Parameters.set("picture-size", ?) take?

    - by mobilekid
    Hi, my app involves some work with the camera, therefore it needs to handle capturing of images with different resolution. My targets are 1.6 - onwards. Does anyone know what to pass in the value argument for Camera.Parameters.set("picture-size", value) I have look at the Donut release of the Camera app, however, it was not very clear what exactly has been used there as the value is retrieved from the SharedPreferences. // Set picture size parameter. String pictureSize = mPreferences.getString(CameraSettings.KEY_PICTURE_SIZE, getString(R.string.pref_camera_picturesize_default)); mParameters.set(PARM_PICTURE_SIZE, pictureSize); Lookin at the strings.xml I can see that R.string.pref_camera_picturesize_default = 2048x1536, however, I'm not sure what other values can be passed there? Is it any resolution you fancy, or are they only certain resolutions the drivers can handle? Thanks.

  • Weird stuttering issues not related to GC.

    - by Smills
    I am getting some odd stuttering issues with my game even though my FPS never seems to drop below 30. About every 5 seconds my game stutters. I was originally getting stuttering every 1-2 seconds due to my garbage collection issues, but I have sorted those and will often go 15-20 seconds without a garbage collection. Despite this, my game still stutters periodically even when there is no GC listed in logcat anywhere near the stutter. Even when I take out most of my code and simply make my "physics" code the below code I get this weird slowdown issue. I feel that I am missing something or overlooking something. Shouldn't that "elapsed" code that I put in stop any variance in the speed of the main character related to changes in FPS? Any input/theories would be awesome. Physics: private void updatePhysics() { //get current time long now = System.currentTimeMillis(); //added this to see if I could speed it up, it made no difference Thread myThread = Thread.currentThread(); myThread.setPriority(Thread.MAX_PRIORITY); //work out elapsed time since last frame in seconds double elapsed = (now - mLastTime2) / 1000.0; mLastTime2 = now; //measures FPS and displays in logcat once every 30 frames fps+=1/elapsed; fpscount+=1; if (fpscount==30) { fps=fps/fpscount; Log.i("myActivity","FPS: "+fps+" Touch: "+touch); fpscount=0; } //this should make the main character (theoretically) move upwards at a steady pace mY-=100*elapsed; //increase amount I translate the draw to = main characters Y //location if the main character goes upwards if (mY<=viewY) { viewY=mY; } }

  • How to calculate the time difference between two time fields , with respect to the date changes

    - by Tiru
    I want to calculate the time difference.I have three EditTexts , I want to input the times in the first two edittexts in HH:MM format. And then calculate the time difference and the result will show on third edittext field in same format. If the date changes, the time difference will calculate according that, i.e If first time = 23:00 and second time = 01:00 then, the time difference = 02:00 hours public class TimeCalculate extends Activity { private String mBlock; private String mBlockoff; private String mBlockon ; // String mHours, mMinutes; Date date1, date2; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); EditText blockoff = (EditText) findViewById(R.id.blockoff); mBlockoff = blockoff.getText().toString(); EditText blockon = (EditText) findViewById(R.id.blockon); mBlockon = blockon.getText().toString(); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("hh:mm"); try { date1 = simpleDateFormat.parse(mBlockoff); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { date2 = simpleDateFormat.parse(mBlockon); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } mBlock = getDifference(date1, date2); EditText block = (EditText) findViewById(R.id.block); block.setText(mBlock.toString()); } public static String getDifference(Date startTime, Date endTime) { if (startTime == null) return "corrupted"; Calendar startDateTime = Calendar.getInstance(); startDateTime.setTime(startTime); Calendar endDateTime = Calendar.getInstance(); endDateTime.setTime(endTime); long milliseconds1 = startDateTime.getTimeInMillis(); long milliseconds2 = endDateTime.getTimeInMillis(); long diff = milliseconds2 - milliseconds1; /*int hours = (int)diff / (60 * 60 * 1000); int minutes = (int) (diff / (60 * 1000)); minutes = minutes - 60 * hours; long seconds = diff / (1000); */ //timeDiff = DateUtils.formatElapsedTime(seconds); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:MM"); Date date = new Date(diff); return simpleDateFormat.format(date); } } I executed this code ,but gives error as Source not found.I think error at getDifference method.Please give any other logic

  • Filter rows from Cursor so they don't show up in ListView

    - by Richard
    I have a Cursor that returns rows I use with a SimpleCursorAdapter to populate a ListView. I would like to filter some of the rows so they don't get displayed in my ListView. I use the data from the rows elsewhere in my Activity so I don't want to change my SQL to filter them with a WHERE clause. What is the best way to keep a row from being displaying in my ListView? Ideally I would check a column in my row and then only add rows to the ListView that satisfy a condition.

  • Can an app delete its own internal resources?

    - by user637884
    I am trying to find a way to delete an internal resource after an app installs. More specifically, I have a zip file included in the apk, that I unzip to the SD Card when the app is first run. But then want to delete the now unneeded zip file (the purpose being to save the user internal phone memory). I access the zip file with, Resources resources = this.getResources(); InputStream is = resources.openRawResource(R.raw.assets); But am uncertain how to then delete the resource (if even possible). I know one may ask why not simply install the app to SD Card at download. But the app includes a screen widget, and installing apps to the SD Card and using a screen widget is problematic. Thanks, Matt
