  • generating function arguments in java

    - by aloishis89
    I'm very new to java and am working on my first Android app. I am using the webview demo as a template. I am trying to generate a random integer between 1 and 12 and then call a certain javascript function based on the result. Here's what I have: int number = 1 + (int)(Math.random() * ((12 - 1) + 1)); number = (int) Math.floor(number); String nextQuote = "javascript:wave" + number + "()"; mWebView.loadUrl(nextQuote); So mWebView.loadUrl(nextQuote) will be the same as something like mWebView.loadUrl("javascript:wave1()") I just want to know if what I have here is correct and will work the way I think it will. The application isn't responding as expected and I suspect this bit of code is the culprit.

  • Help with getParent() downcast.

    - by Preformed Cone
    I'm learning android/java and have this example code I can't get to work: OnRatingBarChangeListener l = new OnRatingBarChangeListener() { public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromTouch) { Integer myPos=(Integer)ratingBar.getTag(); RowModel model=getModel(myPos); model.rating = rating; LinearLayout p=(LinearLayout)ratingBar.getParent(); TextView l=(TextView)p.findViewById(R.id.label); l.setText(model.toString()); } }; Everything works except the LinearLayout / getParent() downcast. At runtime it creates a ClassCastException. If I comment out that block of code then everthing works fine. What am I missing?

  • What happens when I release a upgrade with higher targeted sdk as previous version?

    - by Peterdk
    SoundPool has a serious bug in it in Android 1.5. I fixed it with a workaround, but since it really limits my app, I want to target 1.6+ for the next version of it. I am wondering: What happens when I release a upgrade that has a higher target SDK version then the previous version of my app? Will only 1.6+ users be able to upgrade their app? Or will also the 1.5 users be able to upgrade since they have the program already installed? Anybody experience with this?

  • Unwanted automated creation of new instances of an activity class

    - by Marko
    I have an activity (called Sender) with the most basic UI, only a button that sends a message when clicked. In the onClickListener I only call this method: private void sendSMS(String msg) { PendingIntent pi = PendingIntent.getActivity(this, 0, new Intent(this, Sender.class), 0); PendingIntent pi = PendingIntent.getActivity(this, 0, myIntent, 0); SmsManager sms = SmsManager.getDefault(); sms.sendTextMessage("1477", null, msg, pi, null); } This works ok, the message is sent but every time a message is sent a new instance of Sender is started on top of the other. If I call sendSMS method three times, three new instances are started. I'm quite new to android so I need some help with this, I only want the same Sender to be on all the time

  • Notepad Tutorial: deleteDatabase() function

    - by FelixA
    Hello I have a short question to the notepad tutorial on the android website. I wrote a simple function in the tutorial code to delete the whole database. It looks like this: DataHelper.java public void deleteDatabase() { this.mDb.delete(DATABASE_NAME, null, null); } Notepadv1.java @Override public boolean onCreateOptionsMenu(Menu menu) { boolean result = super.onCreateOptionsMenu(menu); menu.add(0, DELETE_ID, 0, "Delete whole Database"); return result; } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case DELETE_ID: mDbHelper.deleteDatabase(); return true; } return super.onOptionsItemSelected(item); } But when I run the app and try to delete the database I will get this error in LogCat: sqlite returned: error code = 1, msg= no such table: data Can you help how to fix this problem. It seems that the function deleteDatabase can not reach the database. Thank you very much. Felix

  • How to get the line number an xml element is on via the Java w3c dom api

    - by Benju
    Is there a way to lookup the line number that a given element is at in an xml file via the w3c dom api? My use case for this is that we have 30,000+ maps in kml/xml format. I wrote a unit test that iterates over each file found on the hard drive (about 17GB worth) and tests that it is parseable by our application. When it fails I throw an exception that contains the element instance that was considered "invalid". In order for our mapping department (nobody here knows how to program) to easily track down the typo we would like to log the line number of the element that caused the exception. Can anybody suggest a way to do this? Please note we are using the W3C dom api included in the Android 1.6 SDK.

  • Load class based on SDK version

    - by Bostjan
    Is there any way I can load a class based on what version of the OS the phone is running? For example: I made an app which requires 1.6+ Android. Is there a way for me to load one class or the other based on what OS the phone is running? I'm asking this specifically for contacts. The database was changed from 1.6 to 2.0 and the old version doesn't retrieve contacts on the new OS phone. I'd still like to keep my 1.6 requirement, but at the same time I'd like 2.0+ phones to access the contact part of the app. So can I make 2 APIs, somehow pack them with the app and decide on the fly which I choose to import?

  • Packaging "hidden" asset files

    - by ChaimKut
    I'm placing the file '.nomedia' into a folder in order to avoid Android's MediaScanner from detecting the media files in the folder. I need to copy this folder (including '.nomedia') from the APK's assets to the SD card (so other apps can make use of these media files, etc.). When I package the APK in Eclipse, it doesn't package the '.nomedia' file. Presumably it's detecting it as a hidden file. Any ideas how to fix this? Is there a secret aapt flag I can use? I'd like to avoid copying the folder and then manually creating a '.nomedia' folder, if possible.

    New to Android need help with one solid build that I can refer to and study for future projects. The first activity is a background image with a button,when clicked the it takes you to the second activity which is a form with 5 data fields and 2 buttons. One button calls an intent to take a picture within the app and one button that submits the data from the form along with the picture to URL. lastly a third activity that says complete thank you. I can make some of this but don't know how to link button or open and merge camera with the app to be sent as a package of data. I suppose I could also hook into GPS acquire location as well as the camera call?

  • Using variables in Tasker

    - by Waza_Be
    I am trying to create a Tasker plugin. Everything is fine, and works pretty well. I can configure a String to be sent in my app by using EditActivity and this code, following the examples: resultIntent.putExtra(com.twofortyfouram.locale.Intent.EXTRA_BUNDLE,PluginBundleManager.generateBundle(getApplicationContext(),message)); resultIntent.putExtra(com.twofortyfouram.locale.Intent.EXTRA_STRING_BLURB,generateBlurb(getApplicationContext(), message)); setResult(RESULT_OK, resultIntent); The problem comes when I want to use this code to get the battery level for instance, so I added: resultIntent.putExtra("net.dinglisch.android.tasker.extras.VARIABLE_REPLACE_KEYS",com.twofortyfouram.locale.Intent.EXTRA_STRING_BLURB); but the app is not working and I get a string %BATT as the result, the variable is not replaced... As I haven't found any example, I would be pleased to get some help to make it work.

  • How to create a gesture controlled rotating image for a UI

    - by ocdtrekkie
    I'm trying to figure out the best way to make an image rotate along with a user's finger dragging it left or right. I want to try and match the rate a user's finger is moving with the rate the image is rotating. I've got the basic setup for my application going, with the menus and whatnot I want to have, and that's all running great on the emulator, I'm just not sure how to approach this part. I can code all the logic I need for my app, I'm just not doing to well designing the UI, I have a picture in mind, I've actually made a couple mock images of it, I just can't figure out how to get it going in Android, and any help would be appreciated.

    I am trying to send a zipfile from my android application to our server and I keep getting a 411 length required error. Here is the code that I am using to do that.

  • Phonegap and JqueryMobile freeze UI events and functions

    - by techytee
    I am developing a Phonegap app with JQuery mobile with their latest stable versinos (Phonegap 3 and JQM 1.3.2) for Android platform. My app downloads feeds from Google Feeds API and saves in a SQLite database. But whenever it starts fetching and saving data from the web (the no of feeds that download at a time can be many), the other functionality such as button events halt and freeze. To be precise the a button that opens and closes a panel does not either open or close the panel until the data fetching stops. How am I supposed to solve this issue? The performance has dropped drastically due to this issue in my app.

  • Proper programming procedure?

    - by Rob
    I am creating a scoring application which is dependent upon what a user selects at the beginning menu. Example: If a user clicks 18, I want it to base itself off 18 holes of golf. If a user clicks 9, I want it to base itself off 9 holes of golf. Is it better to create a separate class for the code for 9 holes, and then another for 18 holes and then launch whichever depending on what the user selects? Or should I keep everything in 1 file and use a global variable to define different parameters? Still very new to android programming (or programming in general) so not sure of the proper "etiquette" if you will... Also what would be the pro's and con's of doing it either way? (If any) Thanks in advance!

  • Resizing the Camera Preview

    - by uday
    I have implemented a camera application, which will show the preview in the entire screen of the device. But my requirement is to show the Camera preview in a small screen. My device resolution is 800x480(WxH) i.e, Nexus one. I can able to show the preview in the entire screen without scale down the preview. Its coming perfectly, but when i try show the preview in small screens(part of my total mobile screen), the preview is getting stretched and not looking good. Is there any way to show the preview correctly in a small screen. I think we need to scale down the image preview. But when i try to scale down the image preview, the android system itself doesn't allowing to set the scaled preview size. Could any one please help me how to scale the image preview in small screen.

  • Excel VBA: Alternate Row Color in Range

    - by Kurt
    I spent a VERY long time today looking up a method to alternate row colors within a specified range. There really isn't a lot out there and to be honest what I found just looked over-complicated. So, I decided to stop acting like a shameless 'script-kiddy' and put the below sample together: Sub AlternateRowColors() Dim lastRow as Long lastRow = Range("A1").End(xlDown).Row For Each Cell In Range("A1:A" & lastRow) ''change range accordingly If Cell.Row Mod 2 = 1 Then ''highlights row 2,4,6 etc|= 0 highlights 1,3,5 Cell.Interior.ColorIndex = 15 ''color to preference Else Cell.Interior.ColorIndex = xlNone ''color to preference End If Next Cell End Sub Now I know that works, but I was wondering if there's a simpler method? If so, please do tell because I'm very eager to learn simplification as I have a tendency to write verbose code at present. If not, then may this entry find it's way to page 1 of Google for it's search term(s), because it took me absolutely ages to find anything even remotely useful. Comments left for script-kiddies' benefit.

  • Creating hashmap/map from XML resources

    - by KimAMartinsen
    Hi! I'm making an application where a web service fetches (amongst other) a bunch of codes from a webservice (I.e BEL, FRA, SWE). During runtime I want to translate these codes to their apporiate names to display to users (I.e Belgium, France, Sweden). There can be a lot of these codes, so i'm wondering if there is any approriate way to store the (code, name) entry as a some sort of map in the XML resources in Android, so I can quickly fetch the name by the given code? It's all about speed here, since the map can have a few hundred entries.

  • How do you enable Dialer and Mobile Data Settings?

    - by user1461959
    I have a rockchip based Android tv box with heavily modified firmware. The box does not support 3g by default and I am trying to get the mobile data connection to work. I have understood that the Phone.apk and telephony provider apk has to be installed to /system/app. The logs report that the mobile data is enabled and the the phone service is running. However there is no mobile data in Settings and the Dialer app is not shown in launcher application list. What prevents them from showing up ?

  • Sign application with several certificates

    - by tschiggerl
    Hi, From the signing documentation at http://developer.android.com/intl/zh-TW/guide/publishing/app-signing.html: When the system is installing an update to an application, if any of the certificates in the new version match any of the certificates in the old version, then the system allows the update. This indicates that an application can be signed with multiple certificates. This is an interesting option to allow multiple entities to sign an application. e.g: A system application which was initially signed by the device's manufacturer. Further updates could be signed by the developer. Am I misreading the documentation or is this really possible? If so, how? Is there any other way for an application to support different certificates and with that, having two or more entities sign it? Thanks, Rúben

  • Panel in Windows Forms Application not clearing

    - by SwiftStriker00
    I'm working on my project: [Beer Pong Management System][1], a Windows Forms application. I am currently trying to add a whole tournament mode to it. In a nutshell, I've created a TabControl, with the first tab page with the settings and setup and the second page the brackets. There is a feature for each of the match-ups, that once there is a winner is decided, a yellow cancel button will appear in order to revert the tournament. However my issue is when i click the button the next match-up does not get removed in the series is going. See below: Image Here(not high enough rep to insert image) I have tried to set the MatchUp to null, I've tried dispose(), close(). even Parent.Controls.Remove(). Even after I switch tabs which is supposed to clear all, they still sit there when i come back. I have a feeling I might be loosing a reference or something because I can't even push new teams into them, they just sit there with their buttons. Does anyone have any tips or know of any known issues that might be causing this? Thanks. [1] _http://www.cs.rit.edu/~rmb1201/pages/code.shtml

  • Access Assests from another application?

    - by pcm2a
    I get a lot of requests in my application to allow for custom icons packs from BetterCut / Open Home. The way it seems to work is you install BetterCut or Open Home, then you can install tons of these free icon packs from the market. Once installed both those apps (and other apps) will poll for those icon packs and use the icons. I want to know how to poll the install applications for the asset folders that are available. I have opened up a few of the icon packs and verified that there is an assets folder in there and they are full of all the icon png files. I've searched on here, other code sites, google, etc but havn't found any leads.
