  • How do I create a safe local development environment?

    - by docgnome
    I'm currently doing web development with another developer on a centralized development server. In the past this has worked alright, as we have two separate projects we are working on and rarely conflict. Now, however, we are adding a third (possible) developer into the mix. This is clearly going to create problems with other developers changes affecting my work and vice versa. To solve this problem, I'm thinking the best solution would be to create a virtual machine to distribute between the developers for local use. The problem I have is when it comes to the database. Given that we all develop on laptops, simply keeping a local copy of the live data is plain stupid. I've considered sanitizing the data, but I can't really figure out how to replace the real data, with data that would be representative of what people actually enter with out repeating the same information over and over again, e.g. everyone's address becomes 123 Testing Lane, Test Town, WA, 99999 or something. Is this really something to be concerned about? Are there tools to help with this sort of thing? I'm using MySQL. Ideally, if I sanitized the db it should be done from a script that I can run regularly. If I do this I'd also need a way to reduce the size of the db itself. (I figure I could select all the records created after x and whack them and all the records in corresponding tables out so that isn't really a big deal.) The second solution I've thought of is to encrypt the hard drive of the vm, but I'm unsure of how practical this is in terms of speed and also in the event of a lost/stolen laptop. If I do this, should the vm hard drive file itself be encrypted or should it be encrypted in the vm? (I'm assuming the latter as it would be portable and doesn't require the devs to have any sort of encryption capability on their OS of choice.) The third is to create a copy of the database for each developer on our development server that they are then responsible to keep the schema in sync with the canonical db by means of migration scripts or what have you. This solution seems to be the simplest but doesn't really scale as more developers are added. How do you deal with this problem?

  • Development stopped: Is truecrypt unsecure?

    - by Alex Mantel
    I was looking for truecrypt today and found this: http://truecrypt.sourceforge.net/ The page layout changed and claims "truecrypt is unsecure". Futher: "The development of TrueCrypt was ended in 5/2014 after Microsoft terminated support of Windows XP" My Questions: What are the risks for still using truecrypt? Will there be any fork of truecrypt? Is Windows "BitLocker" trustable? Is the reason why the development stopped reliable? Which independent alternatives are there for Linux, MacOS and Windows?

  • why does the gingerbread emulator orientation gets stuck in apps?

    - by tabjsina
    At first I thought this was a problem with my app, but it seems to be happening in any app (though interestingly, not the home screen) in the gingerbread emulator. To replicate my issue, open eclipse and fire up the android emulator for gingerbread (I'm using the "Google APIs - API Level 9" as my target) So the procedure to duplicate once the emulator loads is press LCtrl-F11 to shift orientation to landscape, then again to switch to portrait Result: In the homescreen: The view rotates to landscape, and then back to portrait, as expected In any app (i've tried browser, calculator, maps, and the app i'm currently working on): the view rotates to landscape, and then nothing, it stays in landscape even the emulator is displaying the phone in landscape mode (see below) http://i54.tinypic.com/2ake06v.jpg Has anyone else had this issue, or have I installed the emulator in some incorrect way - this hasn't been an issue with any of the previous emulators

  • Can't pass and retrieve CharSequence to another activity using intent.getExtras() method.

    - by vt
    Activity 1: Intent i = new Intent(this, Activity2.class); CharSequence btText = btButton.getText(); i.putExtra(BUTTON_TEXT, btText); startActivityForResult(i, ACTIVITY_SETTINGS); Activity 2: in onCreate: Bundle extras = getIntent().getExtras(); if (extras != null) { mButtonText = extras.getCharSequence(Activity1.BUTTON_TEXT); } The resulting CharSequence is not what was passed, it's something like "(id=830066506776)" instead. This works: CharSequence test2 = getIntent().getCharSequenceExtra(Activity1.BUTTON_TEXT); What is wrong with getExtras approach? This is what they used in Notepadv3 example. This is for Android 2.1. Thank you.

  • Reader for Android Updates; Now with Feed Widgets and More

    - by ETC
    Android phone owners rocking the official Google Reader app will be pleased to see the new update includes much requested features such as polished feed widgets, unread counter widgets, and a handy “mark previous as read” button. Widgets have long been one of the most requested feature for Google Reader for Android. This update rolls them out in two forms. News ticker widgets show you current headlines for your Google Reader folders (as seen in the screenshot here); folder widgets function just as unread counters and only take up a 1×1 space. In addition to the widgets another much requested feature made an appearance. While scrolling through your feed you can now mark all the previous entries as read.

  • Edit Contact code worked in 1.6 but doesn't work on Droid 2.1?

    - by user225405
    Hi All, I had some fairly simple code in my app to invoke Edit Contact activity on a known good contact index that worked in Android 1.6 but is broken for me now in Android 2.1 on the Droid. I built a sample activity/app 'EdCon' to show this: package com.jbh; import android.app.Activity; import android.content.Intent; import android.net.Uri; import android.os.Bundle; public class EdCon extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Build an intent to edit a known good contact index Intent i; i = new Intent(Intent.ACTION_EDIT); i.setData(Uri.parse("content://contacts/people/10")); startActivity(i); } } When I run this on my G1 running 1.6 it works as expected i.e. brings up the Edit Contact screen for the known index and then I can hit BACK to return to "Hello World, EdCon". When I run this on the Droid under 2.1 I get the following: 05-07 15:35:57.787: INFO/ActivityManager(1013): Starting activity: Intent { act=android.intent.action.MAIN

  • Android Video Camera : still picture

    - by Alex
    I use the camera intent to capture video. Here is the problem: If I use this line of code, I can record video. But onActivityResult doesn't work.

  • Acceptable sound quality: stereo needed for an Android game?

    - by Thomas Calc
    I have various simple short sound effects (damage sound, dying sound, thunderbolt, fanfare, breaking) for a game that is developed for Android currently. I use OGG files: 96kbps VBR, 44.1KHz, 2 channels (that means stereo, right?). I read the other stackexchange topics about "acceptable sound quality", but they're too general, address too many things. My experience is that even with 80kbps, my effects sound OK. But I tested it on a limited number of Android devices (including a Sony Ericsson Xperia Neo and a HTC Desire HD). My questions: For mobile phones and tablets, generally, what parameters are recommended? Won't my 80kbps sounds be bad on a newer device (such as a modern tablet)? I don't hear any difference between stereo and mono (2 channels vs. 1 channel, right?), is there any noticeable difference at all for mobile phones / tablets? (in terms of the player experience) May it worth it at all? I assume that stereo sounds take much more in memory (when they're decoded to PCM), despite of the fact that the compressed OGG size is practically the same. Reacting to Roy T.'s great comment: Actually, I couldn't measure the PCM size (Android decodes OGG internally), but I thought that stereo will take more space than mono when uncompressed After throwing out one of the WAV channels in Audacity, and re-exporting it: The new WAV file size is half than before The OGG file size is practically the same as before The sound effects and game music was recorded by my friend who is an experienced hobby musician/composer, but he knows little about computers & software so he just gave me some high-quality WAV files generated via his hardware.These were stereo, but if I check them in Audacity, both channels appear to be exactly the same.Can I consider them the same (= moving to mono), or might there be some unnoticeable differences to the human eye?

  • HTC Incredible displaying blank ImageView

    - by Todd
    HI, I have an app that displays an an image in an ImageView using the setImageDrawable(Drawable) method. However, with the release of the Droid Incredible the images are coming up as a blank screen. I am using Drawable.createFromPath(Environment.getExternalStorageDirectory() + "\imagefile") to access the image from the SD card. I don't get any sort of error, just a black screen. I will get a null pointer exception if after trying to load the image I try to access a property of the Drawable. This makes me believe that the Drawable wasn't loaded, but I don't know why or how to make it work. This code as been working on all other Android devices, so I'm not sure what is different with the Incredible. Unfortunately I don't have access to an Incredible to test on, so I've got to rely on others to test and send me the log files. Any help you can offer would be greatly appreciated. If anyone knows how to replicate this issue on the emulator, that would be helpful too. I've configured an emulator with firmware 7 and the correct screen resolution, but I was unable to replicate the issue. Thanks.

  • Rows added to table are not showing up

    - by Lars
    This has been asked before, but I have found no solution that worked for me yet: When adding rows to a table from code, the rows are not showing up in the application. There is one row I specified in XML, that one is showing up, but nothing below it. This is the code: public void addRow(LocationMessage locationMsg){ View messageView = theInflater.inflate(R.layout.homepage, null); TableLayout table = (TableLayout)messageView.findViewById(R.id.distanceTable); TextView senderNameTextView = new TextView(thisContext); senderNameTextView.setText(locationMsg.getSenderName()); TableRow tr = new TableRow(thisContext); tr.addView(distanceTextView); table.addView(tr); rows.addFirst(messageView); } homepage.xml contains this, I removed some elements and parameters: <?xml version="1.0" encoding="utf-8"?> <LinearLayout> <TabHost> <TabWidget /> <FrameLayout> [..] <LinearLayout> [..] <TableLayout android:id="@+id/distanceTable" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_gravity="center" android:background="#DDDDDD" android:stretchColumns="1" > <TableRow> <TextView android:textColor="#000000" android:text="@string/label_device" android:layout_gravity="center" android:padding="3dip" android:textSize="18sp" /> <TextView android:textColor="#000000" android:text="@string/label_distance" android:layout_gravity="center" android:padding="3dip" android:textSize="18sp" /> <TextView android:textColor="#000000" android:text="@string/label_time" android:layout_gravity="center" android:padding="3dip" android:textSize="18sp" /> </TableRow> </TableLayout> </LinearLayout> </FrameLayout> </TabHost> </LinearLayout> Unfortunately hierarchyviewer.bat doesn't work for me in order to check if the rows are there but just not visible. In the debugger it looks fine to me.

  • AvoidXferMode Tolerance

    - by kayahr
    I have a problem with the following code: protected void onDraw(Canvas canvas) { Paint paint = new Paint(); // Draw a blue circle paint.setColor(Color.BLUE); canvas.drawCircle(100, 100, 50, paint); // Draw a red circle where it collides with the blue one paint.setXfermode(new AvoidXfermode(Color.BLUE, 0, Mode.TARGET)); paint.setColor(Color.RED); canvas.drawCircle(50, 50, 50, paint); } According to the API documentation of AvoidXfermode the tolerance value 0 means that it looks for an EXACT color match. This should work here because I specify the same color as I used for drawing the first circle. But the result is that the red circle is not drawn at all. When I use a tolerance value of 255 instead then it works (red circle is drawn where it collides with the blue one) but that sounds wrong because with such a high tolerance I think it should draw the circle EVERYWHERE. So what's wrong here? API Documentation? Android? Me?

  • Why doesn't my text be bold when displaying on device screen

Why it is not bold??

  • How can I find out if the MainActivity is being paused from my Java class?

    - by quinestor
    I am using motion sensor detection in my application. My design is this: a class gets the sensor services references from the main activity and then it implements SensorEventListener. That is, the MainActivity does not listen for sensor event changes: public void onCreate(Bundle savedInstanceState) { // ... code mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); // The following is my java class, it does not extends any android fragment/activty mShakeUtil = new ShakeUtil(mSensorManager,mAccelerometer,this); // ..more code.. } I can't redesign ShakeUtil so it is a fragment nor activity, unfortunately. Now to illustrate the problem consider: MainActivity is on its way to be destroyed/paused. I.e screen rotation ShakeUtil's onSensorChanged(SensorEvent event) gets called in the process.. One of the things that happen inside onSensorChanged is a dialog interaction, which gives the error: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState When the previous happens between MainActivity's onSaveInstanceState and onPause. I know this can be prevented if I successfully detect that MainActivity is being pause in ShakeUtil. How can I detect that MainActivity is being paused or onSaveInstanceState was called from ShakeUtil? Alternatively, how can I avoid this issue without making Shakeutil extend activity? So far I have tried with flag variables but that isn't good enough, I guess these are not atomic operations. I tried using Activity's isChangingConfigurations(), but I get an undocummented "NoSuchMethodFound" error.. I am unregistering the sensors by calling ShakeUtil when onPause in main ACtivity

  • overridePendingTransition doesn't work

    - by Ixx
    Have found already some people asking the same, but the solutions didn't work for me. I see no animation. Calling it this way: Intent intent = new Intent(this, MyActivity.class); startActivity(intent); overridePendingTransition(R.anim.fadein, R.anim.fadeout); fadein.xml and fadeout.xml are in the anim folder: fadein.xml: <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" > <alpha android:duration="1000" android:fromAlpha="0.0" android:interpolator="@android:anim/accelerate_interpolator" android:toAlpha="1.0" /> </set> fadeout.xml: <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <alpha android:duration="1000" android:fromAlpha="1.0" android:interpolator="@android:anim/accelerate_interpolator" android:toAlpha="0.0" /> </set> Using min. API 7: manifest: <uses-sdk android:minSdkVersion="7"/> API 7 is also in my project.properties file: target=android-7 What am I doing wrong? P.D. Removing the lines with the interpolator doesn't change anything.

  • metro style on windows and android

    - by MRM
    I want to develop a rather simple app using windows 8 metro style for GUI. But i need this app to have the same appearance, GUI, for both platforms, so that end users that uses it both on PC and a mobile device to have the same visual experience and a flawless navigation. So, does anyone have knowledge of a Java framework or library to satisfy these needs? Or maybe a method to create a web-based app using HTML, PHP, JScript etc. (maybe something using a local server, on the same machine, because a web server is out of discussion, at least for the moment)? Any idea, method, technology related to the subject is also helpful. And if what you are thinking at can be used for IOS too, the better.

  • Dark or light theme for Android apps?

    - by Philip Sheard
    My app allows the user to choose between a dark and a light theme, but which should it use as the default? It is a field sales app, a kind of glorified invoicing app for enterprise users. It is much larger than most apps in Google Play, and targets a vertical market. Originally I developed the app with a dark font, which was fairly standard at the time. That is still my personal preference, but most modern apps seem to have a light font.
