  • Loading SQLite Database into Android App

    - by Chris
    I am able to create, write and read an SQLite Database in my Android App. I have a copy of the Database that is fully populated with data, and I want to get that data into the App's Database. Is it possible to access my pouplaed database from inside my App? Or can I at least create a copy of the populated database and then use that copy? Or do I need to do a .dump and put all the inserts into the Android code?

  • Can each mobile app have its own client account for payments? (Windows Phone, Android and iPhone)

    - by Luckyl337
    My company has many clients wanting mobile applications and having the payments come into our account and then sorting the payments would be a real pain. So can a company have a main account to publish applications (free and chargeable) and still have some sort of client account for each app (so they could view sales and receive full payment directly)? I would like to know for Windows, Android and Apple please.

  • resultCode is always 0

    - by Aaron T
    I'm trying to get the resultCode to be OK inside my onActivityResult function. However, it keeps coming back as 0. I have spent several days on this, and can't figure out why it doesn't work. Here's my code. If anybody can help me, I'll be very grateful, Thanks. My Activity1 class: private class MyTask extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... urls) { // process return result; } @Override protected void onPostExecute(String result) { Intent i = new Intent(Activity1.this, Activity2.class); i.putExtra("Value1", "This value one for ActivityOne "); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivityForResult(i, REQUEST_CODE); textView.setText(result); } } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == RESULT_OK && requestCode == REQUEST_CODE) { // do something } } My Activity 2 class: @Override public void finish() { Intent data = new Intent(); data.putExtra("returnKey1", "return 1"); setResult(RESULT_OK, data); super.finish(); } My manifest: <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".Activity1" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".Activity2" android:label="@string/app_dialog_name" android:launchMode="singleTop" android:excludeFromRecents="true" android:taskAffinity="" android:theme="@android:style/Theme.Dialog"> </activity> </application>

  • Huh? JDK not found? (on Windows 7 64-bit)

    - by Android Eve
    I am setting up a development environment for the latest Android 2.3 on a fresh install of Windows 7 64-bit. I first installed the 64-bit JDK 6 (jdk-6u23-windows-x64.exe). Then, I installed 64-bit Eclipse Classic 3.6 (eclipse-SDK-3.6.1-win32-x86_64.zip). Then, I proceed to install the Android SDK Starter Package: installer_r08-windows.exe. But... upon start it says: "Java SE Development Kit (JDK) not found." Why? I just installed it. Is this a mismatch between 32-bit and 64-bit? How do I solve this? Update (1): I tried setting the %JAVA_HOME% environment variable, as well as setting the Installed JREs in Eclipse, as suggested below. None of these solved the problem. It appears that I am not the only experiencing the problem, as this thread suggests: http://stackoverflow.com/questions/1919340/android-sdk-setup-under-windows-7-pro-64-bit I wonder whether there is a 64-bit version of the Android SDK. Update (2): I used the zip version instead (android-sdk_r08-windows.zip), ran android.bat, updated all SDK packages, and installed the ADT plugin (8.0.1), not before having to check: 'Contact all update sites during install to find required software'. We'll see how this goes... Update (3): It worked! (going to accept @bubu's answer shortly) -- but why doesn't the emulator include the HelloAndroid app when I run it (Ctrl+F11) from Eclipse?

    - by user1796310
    I'm trying to create android apps which able sending data through wifi connection to my laptop Apache Server and MySQL database. I use the samsung galaxy tab 10.1 as my mobile device. and the protocol i used is HttpGet or HttpPost. And i use XAMPP( with Apache& SQL) to do the server and process the php. But, due to android cannot detect adhoc network from laptop, i use Virtual Router ( for window 7) to create virtual access point and make the tablet able connect to my laptop. But the problem is: [1] in my apps (client-android), where the httpget or httppost to which url? localhost in my laptop- 127.0.0.1 or localhost in android 10.0.0.1? or the ip address of the virtual router? [2]so, if i want access from android to the localhost(laptop-Apache) to call the php to run? which port? which ip address /url that i need to put in android apps(httpget)? and do i need to modify anything in httpconfig for XAMPP? thanks alot.

  • How do I build mDNSResponder?

    - by Alex
    I have tried checking out the mDNSResponder source from Apple's SVN host, with the thought of compiling it and tweaking it. This failed miserably. Here is the last line of the output of cd trunk SRCROOT=. make I get the same error for several tags in the SVN tree, so I'm not sure if there is something on my end wrong? The following build commands failed: mDNSResponder: CompileC mDNSResponder.build/mDNSResponder.build/Objects-normal/i386/mDNSMacOSX.o /Users/myname/Desktop/mDNSResponder/trunk/mDNSMacOSX/mDNSMacOSX.c normal i386 c com.apple.compilers.gcc.4_2 PhaseScriptExecution "Run Script" /Users/myname/Desktop/mDNSResponder/trunk/mDNSMacOSX/mDNSResponder.build/mDNSResponder.build/Script-D284BE6C0ADD80740027CCDF.sh mDNSResponder debug: CompileC "mDNSResponder.build/mDNSResponder debug.build/Objects-normal/i386/mDNSMacOSX.o" /Users/myname/Desktop/mDNSResponder/trunk/mDNSMacOSX/mDNSMacOSX.c normal i386 c com.apple.compilers.gcc.4_2 Build Some: PhaseScriptExecution "Run Script" "/Users/myname/Desktop/mDNSResponder/trunk/mDNSMacOSX/mDNSResponder.build/Development/Build Some.build/Script-FF045B6A0C7E4AA600448140.sh" (4 failures)

  • HTC Android Fails to mount- Mount from computer?

    - by Ben Franchuk
    I Have an HTC Incredible S (S-Off, Rooted, ViperVIVO 1.3.0 ICS) that has seemingly ceased to posses the ability to mount its SD Storage to my computer. For whatever reason, whenever I plug in my device to transfer files from computer to phone and vice versa, the computer, for some reason, cannot actually aces the phone. I get prompted with a window on my phone when I first plug it in, asking me which mode I want to put the device into (Charge mode, tether mode, etc.), and even if I select the "Disk Drive" function, the phone still cannot successfully mount to my computer. The phone itself unmounts itself from the SD and says that the computer is connected, but again, it doesn't work. Is there any way to force mount the device from my computer- either via command or otherwise? This should help in that if I unmount the SD from the phone I should be able to mount it to my computer, from my computer, Correct?

  • Android tethering via bluetooth keeps disconnecting

    - by Ian
    I'm currently using a Google Nexus tablet tethered via Bluetooth to a Samsung S3 for internet. Two things are annoying me. First, if I take the phone away from the tablet (go out for lunch), the tablet disconnects and has to be manually reconnected. Is there a way to have that happen automatically? Second, Bluetooth tethering, i.e. the internet sharing part needs to be switched on each time the bluetooth is switched on (or perhaps just after power cycling) on the S3. Is there no way to have that default to on? Thanks

  • Build error while compiling Android source (JNI)

    - by arTsmarT
    I added some new functionality in C and when I try to build it, it gives me the following error: libnativehelper/include/nativehelper/JNIHelp.h:116: error: undefined reference to 'jniRegisterNativeMethods' error. I have included jnihelp.h in my C files. Is this a makefile related issue or am I missing something?

  • How to use Android's CacheManager?

    - by punnie
    I'm currently developing an Android application that fetches images using http requests. It would be quite swell if I could cache those images in order to improve to performance and bandwidth use. I came across the CacheManager class in the Android reference, but I don't really know how to use it, or what it really does. I already scoped through this example, but I need some help understanding it: /core/java/android/webkit/gears/ApacheHttpRequestAndroid.java Also, the reference states: "Network requests are provided to this component and if they can not be resolved by the cache, the HTTP headers are attached, as appropriate, to the request for revalidation of content." I'm not sure what this means or how it would work for me, since CacheManager's getCacheFile accepts only a String URL and a Map containing the headers. Not sure what the attachment mentioned means. An explanation or a simple code example would really do my day. Thanks! Update Here's what I have right now. I am clearly doing it wrong, just don't know where. public static Bitmap getRemoteImage(String imageUrl) { URL aURL = null; URLConnection conn = null; Bitmap bmp = null; CacheResult cache_result = CacheManager.getCacheFile(imageUrl, new HashMap()); if (cache_result == null) { try { aURL = new URL(imageUrl); conn = aURL.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); cache_result = new CacheManager.CacheResult(); copyStream(is, cache_result.getOutputStream()); CacheManager.saveCacheFile(imageUrl, cache_result); } catch (Exception e) { return null; } } bmp = BitmapFactory.decodeStream(cache_result.getInputStream()); return bmp; }

  • Scrolling a Canvas smoothly in Android

    - by prepbgg
    I'm new to Android. I am drawing bitmaps, lines and shapes onto a Canvas inside the OnDraw(Canvas canvas) method of my view. I am looking for help on how to implement smooth scrolling in response to a drag by the user. I have searched but not found any tutorials to help me with this. The reference for Canvas seems to say that if a Canvas is constructed from a Bitmap (called bmpBuffer, say) then anything drawn on the Canvas is also drawn on bmpBuffer. Would it be possible to use bmpBuffer to implement a scroll ... perhaps copy it back to the Canvas shifted by a few pixels at a time? But if I use Canvas.drawBitmap to draw bmpBuffer back to Canvas shifted by a few pixels, won't bmpBuffer be corrupted? Perhaps, therefore, I should copy bmpBuffer to bmpBuffer2 then draw bmpBuffer2 back to the Canvas. A more straightforward approach would be to draw the lines, shapes, etc. straight into a buffer Bitmap then draw that buffer (with a shift) onto the Canvas but so far as I can see the various methods: drawLine(), drawShape() and so on are not available for drawing to a Bitmap ... only to a Canvas. Could I have 2 Canvases? One of which would be constructed from the buffer bitmap and used simply for plotting the lines, shapes, etc. and then the buffer bitmap would be drawn onto the other Canvas for display in the View? I should welcome any advice! Answers to similar questions here (and on other websites) refer to "blitting". I understand the concept but can't find anything about "blit" or "bitblt" in the Android documentation. Are Canvas.drawBitmap and Bitmap.Copy Android's equivalents?

  • Making a Text-To-Speech Wrapper in Android

    - by John Montgomery
    I am attempting to create a wrapper class for Google Android's Text-To-Speech functionality. However, I'm having trouble finding a way to have the system pause until after the onInit function has finished. Attached at the bottom is something of a solution I created based on what I found here: http://stackoverflow.com/questions/1160876/android-speech-how-can-you-read-text-in-android However, this solution does not seem to work. Any thoughts on why this might not be working, or what would be a good idea in order to make sure that any Speak() calls happen after my onInit() call? public class SpeechSynth implements OnInitListener { private TextToSpeech tts; static final int TTS_CHECK_CODE = 0; private int ready = 0; private ReentrantLock waitForInitLock = new ReentrantLock(); SpeechSynth( Activity screen ) { ready = 0; tts = new TextToSpeech( screen, this ); waitForInitLock.lock(); } public void onInit(int status) { if (status == TextToSpeech.SUCCESS) { ready = 1; } waitForInitLock.unlock(); } public int Speak( String text ) { if( ready == 1 ) { tts.speak(text, TextToSpeech.QUEUE_ADD, null); return 1; } else { return 0; } } } I have been able to make it so that I can pass a string of text through the constructor, then have it played in the onInit() function. However, I would really like to avoid having to destroy and re-create the whole text-to-speech engine every time I need to have my program say something different.

  • Android: Creating a Scrollable Layout

    - by MD
    I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now. The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application. Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through. I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful. EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)

  • Storing data on SD Card in Android

    - by BBoom
    Using the guide at Android Developers (http://developer.android.com/guide/topics/data/data-storage.html) I've tried to store some data to the SD-Card. This is my code: // Path to write files to String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/"+ctxt.getString(R.string.package_name)+"/files/"; String fname = "mytest.txt"; // Current state of the external media String extState = Environment.getExternalStorageState(); // External media can be written onto if (extState.equals(Environment.MEDIA_MOUNTED)) { try { // Make sure the path exists boolean exists = (new File(path)).exists(); if (!exists){ new File(path).mkdirs(); } // Open output stream FileOutputStream fOut = new FileOutputStream(path + fname); fOut.write("Test".getBytes()); // Close output stream fOut.flush(); fOut.close(); } catch (IOException ioe) { ioe.printStackTrace(); } When I create the new FileOutputStream I get a FileNotFound exception. I have also noticed that "mkdirs()" does not seem to create the directory. Can anyone tell me what I'm doing wrong? I'm testing on an AVD with a 2GB sd card and "hw.sdCard: yes", the File Explorer of DDMS in Eclipse tells me that the only directory on the sdcard is "LOST.DIR".
