SSD -- Special settings for SSD as secondary drive?

- by Borg17of20

Hello all, I recently purchased an Intel SSD (X25-V 40GB) and I want to add it to my PC as a secondary drive (not the boot/system drive) so I can install specific software to it. Now, do I need to do anything special to ensure long life and peak performance with this as a secondary drive? I have Windows 7 Pro. by the way. All the literature I can find covers the use of a SSD as a boot/system drive under Windows 7, but I don't want to run it like that (I have my reasons). I'm wondering if things like TRIM still work if you don't use the SSD as the boot/system drive. If TRIM and the like still works, do I have to do anything special in order to enable it for my particular setup? Thanks.

Android -- Can't play any videos (mp4/mov/3gp/etc.)?

- by borg17of20

Hello all, I'm having great difficulty getting my Android application to play videos from the SD card. It doesn't matter what size, bitrate, video format, or any other setting I can think of, neither the emulator nor my G1 will play anything I try to encode. I've also tried a number of videos from the web (various video formats, bitrates, with and without audio tracks, etc.), and none of those work either. All I keep getting is a dialog box that says: "Cannot play video" "Sorry, this video cannot be played." There are errors reported in LogCat, but I don't understand them and I've tried searching the Internet for further explanations without any luck. See below: 03-30 05:34:26.807: ERROR/QCOmxcore(51): OMXCORE API : Free Handle 390d4 03-30 05:34:26.817: ERROR/QCOmxcore(51): Unloading the dynamic library for OMX.qcom.video.decoder.avc 03-30 05:34:26.817: ERROR/PlayerDriver(51): Command PLAYER_PREPARE completed with an error or info PVMFErrNoResources 03-30 05:34:26.857: ERROR/MediaPlayer(14744): error (1, -15)03-30 05:34:26.867: ERROR/MediaPlayer(14744): Error (1,-15) Sometimes I also get this: 03-30 05:49:49.267: ERROR/PlayerDriver(51): Command PLAYER_INIT completed with an error or info PVMFErrResource 03-30 05:49:49.267: ERROR/MediaPlayer(19049): error (1, -17) 03-30 05:49:49.347: ERROR/MediaPlayer(19049): Error (1,-17) Here is the code I'm using (in my onCreate() method): this.setContentView(R.layout.main); //just a simple VideoView loading files from the SD card VideoView myIntroView = (VideoView) this.findViewById(R.id.VideoView01); MediaController mc = new MediaController(this); myIntroView.setMediaController(mc); myIntroView.setVideoPath("/sdcard/test.mp4"); myIntroView.requestFocus(); myIntroView.start(); Please help!

c#/.NET SQLite -- REINDEX not working?

- by borg17of20

Hello all, I'm trying to reindex a table in a simple database that I created using SQLite.NET and VS2008. I need to reindex tables after every DELETE command and here is the code snippet I have written (it does not work): SQLiteCommand currentCommand; String tempString = "REINDEX tf_questions"; //String tempString = "REINDEX [main].tf_questions"; //String tempString = "REINDEX main.tf_questions"; currentCommand = new SQLiteCommand(myConnection); currentCommand.CommandText = tempString; currentCommand.ExecuteNonQuery() When run within my program, the code produces no errors, but it also doesn't reindex the "tf_questions" table. In the above example, you will also see the other query strings I've tried that also don't work. Please help, Thanks

Android -- How to position View off-screen?

- by borg17of20

Hello all, I'm trying to animate a simple ImageView in my application and I want it to slide in from the bottom of the screen and come to a resting position where the top 50px of the view is off the top of the screen (e.g. the final position of the ImageView should be -50px in X). I've tried to use the AbsoluteLayout to do this, but this actually cuts off the top 50px of the ImageView such that the top 50px is never rendered. I need to have the top 50px of the ImageView visible/rendered while it's animating and then simply have it come to a rest slightly off-screen. I hope I've explained that well enough. Here is what I'm currently using as a layout and the slide-in animation (this currently doesn't render the top 50px of the ImageView): Layout: <?xml version="1.0" encoding="utf-8"?> <AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent" android:id="@+id/QuickPlayClipLayout"> <ImageView android:id="@+id/Clip" android:background="@drawable/clip" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_y="-50dp"> </ImageView> </AbsoluteLayout> Animation: <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:fromYDelta="100%p" android:toYDelta="0" android:duration="1000"/> <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="1000" /> </set> Thanks in advance.

Android/Java -- Post simple text to Facebook wall?

- by borg17of20

Hello all, I'm trying to integrate posting to one's wall from within my app. I already have an area where the user can save his/her username and password (encrypted). I would like my program to recall the saved username and password, pass that to Facebook for authentication, and then allow the app to post simple text (maybe a link too) to the user's wall. That said, I've read everything on the developer pages at Facebook (the api looks completely foreign to me... I've never don't any type of web app development before... just desktop apps), and experimented with the Java libraries here: http://wiki.developers.facebook.com/index.php/User:Java but to be honest, I don't understand any of the various implementations. Some claim to be simple to use, but apparently they are all way above my head. I've even tried messing with the official Facebook Android SDK, but that uses a webview interface, and I can't pass in the username and password for easy authentication. Plus, I'm still clueless as to how to post to the wall even after correct authentication. Please help. Thanks. Oh, btw I already have a Facebook API key and Application ID.

NotFoundException in layout editor for Android?

- by borg17of20

I'm trying to extend a RelativeLayout object and include an embedded SurfaceView object that uses a png file in my /res/drawable folder as its background but I keep getting an error in the XML Layout editor. See the following code: public class StopMotionRelativeLayout extends RelativeLayout { private Context myContext; private SurfaceView surfaceView1; private BitmapFactory.Options myBitmapOptions; private final android.view.ViewGroup.LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT, android.view.ViewGroup.LayoutParams.FILL_PARENT); public StopMotionRelativeLayout(Context context, AttributeSet attrs) { super(context, attrs); myContext = context; this.setBackgroundColor(Color.GREEN); //init images surfaceView1 = new SurfaceView(myContext,attrs); surfaceView1.setVisibility(View.INVISIBLE); this.addView(surfaceView1, params); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); myBitmapOptions = new Options(); myBitmapOptions.outWidth = widthMeasureSpec; myBitmapOptions.outHeight = heightMeasureSpec; surfaceView1.setBackgroundDrawable(new BitmapDrawable(BitmapFactory.decodeResource(this.myContext.getResources(), R.drawable.golf1, myBitmapOptions))); } } I get the following error: NotFoundException: Could not find drawable resource matching value 0x7F020002 (resolved name: golf1) in current configuration. I have seen this type of error may times now and it always happens when I try to load something from a resource file via code and not XML. Curiously, this error does not stop me from compiling the app, and the app runs without error in the emulator. I'd like to get back the use of my layout editor though... Please help. UPDATE: Here is the layout XML <?xml version="1.0" encoding="utf-8"?> <com.games.test.StopMotionRelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> </com.games.test.StopMotionRelativeLayout>

Android -- SDK/IDE Layout Bug (w/Custom Layouts)??

- by borg17of20

Hello all, Can someone tell me if this is a bug in the SDK/IDE: Any custom or extended layout I add to my layout XML causes the IDE to ignore the fact that there are any child views of that layout (they just disappear from the outline view/window), thus making them uneditable via the properties view/window. (I need to extend a layout to make onSetAlpha() public) FYI: I'm developing for Android 1.5 and up, using all the latest plug-ins/updates in Eclipse Here is a simple example of a layout XML and the extended Layout that causes this error. [Extended Layout] package com.test; public class CustomLinearLayout extends LinearLayout { public CustomLinearLayout(Context context, AttributeSet attrs) { super(context, attrs); } public CustomLinearLayout(Context context) { super(context); } } [Simple layout XML] <?xml version="1.0" encoding="utf-8"?> <com.test.CustomLinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <ImageView android:id="@+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView> </com.test.CustomLinearLayout> ImageView01 is not visible or editable in the properties or outline views/windows. Thanks.

Android -- How to post app rating/comments to Market from within app?

- by borg17of20

Hello all, This is a simple question. Is there a way to allow users to enter in a comment and or rating for my app from directly within my app and have that data posted back to the Android Market? If so, what would the code for that look like if I used an EditText view to allow user input? If not, then is my only other option directly linking to my app in the Market (i.e. the user clicks the link in my app, or a button, and the Market app launches with my app page displayed)? For example: view.setOnClickListener( new OnClickListener(){ public void onClick(View v) { startActivity( new Intent( Intent.ACTION_VIEW, Uri.parse("market://details?id=packagename") ) ); } } *where "packagename" is replaced by my app's package name from the manifest. Thanks.

Android -- Object Creation/Memory Allocation vs. Performance

- by borg17of20

Hello all, This is probably an easy one. I have about 20 TextViews/ImageViews in my current project that I access like this: ((TextView)multiLayout.findViewById(R.id.GameBoard_Multi_Answer1_Text)).setText(""); //or ((ImageView)multiLayout.findViewById(R.id.GameBoard_Multi_Answer1_Right)).setVisibility(View.INVISIBLE); My question is this, am I better off, from a performance standpoint, just assigning these object variables? Further, am I losing some performance to the constant "search" process that goes on as a part of the findViewById(...) method? (i.e. Does findsViewById(...) use some sort of hashtable/hashmap for look-ups or does it implement an iterative search over the view hierarchy?) At present, my program never uses more than 2.5MB of RAM, so will assigning 20 or so more object variables drastically affect this? I don't think so, but I figured I'd ask. Thanks.
